The Arcati Mainframe Yearbook has been the de facto reference work for IT professionals working with z/OS (and its forerunner) systems since 2005. The Yearbook includes an annual user survey, an up-to-date directory of vendors and consultants, a media guide, a strategy section with papers on mainframe trends and directions, a glossary of terminology, and a technical specification section. Each year, the Yearbook is downloaded by around 20,000 mainframe professionals. The current issue is still available at www.arcati.com/newyearbook13.
Very shortly, many mainframe professionals will receive an e-mail telling them that Mark Lillycrop and I have started work on the 2014 edition of the Arcati Mainframe Yearbook. If you don’t hear from us, then e-mail arcati@itech-ed.com and I will add you to our mailing list.
As in previous years, we’re inviting mainframe professionals to complete the annual user survey, which will shortly be up and running at www.arcati.com/usersurvey14. The more users who complete the survey, the more accurate and therefore useful the survey report will be. All respondents before Friday 6 December will receive a free PDF copy of the survey results on publication. The identity and company information of all respondents is treated in confidence and will never be divulged to third parties. And any comments made by respondents will be anonymized before publication. If you go to user group meetings, IOD, GSE Europe, etc, or just hang out with mainframers from other sites, please pass on the word about this survey. We’re hoping that this year’s user survey will be the most comprehensive survey ever. Current estimates suggest that there are somewhere between 3,000 and 4,000 mainframes in use worldwide.
Anyone reading this who works for a vendor, consultant, or service provider, can ensure their company gets a free entry in the vendor directory section by completing the form, which will be at www.arcati.com/vendorentry. This form can also be used to amend last year’s entry.
Also, as in previous years, there is an opportunity for organizations to sponsor the Yearbook or take out a half-page advertisement. Half-page adverts (5.5in x 8.5in max landscape) cost $810 (UK£500). Sponsors get a full-page advert (11in x 8.5in) in the Yearbook; inclusion of a corporate paper in the Mainframe Strategy section of the Yearbook; a logo/link on the Yearbook download page on the Arcati Web site; and a brief text ad in the Yearbook publicity e-mails sent to users. All this for just $2300 (UK£1400).
To put that cost into perspective: for every dollar you spend on an advert, you reach around 25 mainframe professionals.
The Arcati Mainframe Yearbook 2014 will be freely available for download early in January next year.

New Business Class baby
Anyone who’s been on holiday this week would probably have been holidaying on Mars to have missed Tuesday’s excited announcement from IBM of its new zBC12 mainframe computer! The zBC12 follows last year’s announcement of the zEC12 (Enterprise Class), 2011 saw the z114, and 2010 gave us the z196. So what’s special about the new baby?
Well, the zEnterprise BC12 (zBC12) features a 4.2GHz processor, and, for cloud computing, it can consolidate up to 40 virtual servers per core or up to 520 in a single footprint. It offers similar capabilities to the IBM zEC12, including specialty processors. There’s the Integrated Facility for Linux (IFL) engine for running Linux applications, and the System z Application Assist Processor (zAAP) and System z Integrated Information Process (zIIP) for off-core workload processing. The big difference is that the zBC12 has a maximum memory of 496GB compared to the zEC12’s maximum of 3TB, and it has more limited connectivity options.
If you need to ask the price, as they say, you can’t afford it, but a new zBC12 starts at $75,000, which is a very good price tag. IBM also claims that it can help customers save up to 55% over their x86 distributed environments.
One big difference with this year’s announcement is that IBM is also launching a Linux-only based version of the zBC12, which it’s calling the Enterprise Linux Server (ELS). This is aimed at first-time zEnterprise users. The deal is that the product includes hardware, hypervisor, and three-years of maintenance service, plus, it can be upgraded to analytics and cloud mainframe products. I think that’s called upselling!
IBM also released Version 6.3 of z/VM, which supports up to 1TB of real memory, enabling support for more virtual servers than any other platform in a single footprint. It’s also enabled for OpenStack for advanced enterprise-wide service management. In addition, there’s z/OS Version 2.1, which, among all its other features, is very good at securing private cloud workloads.
IBM claims that when integrated with DB2 Analytics Accelerator, the zBC12 can perform business analytics workloads with response times up to nine times faster, with 10 times better price performance, and 14 percent lower total cost of acquisition than the closest competitor. I wonder who they mean by that??
For cloud computing, IBM has enhanced its OMEGAMON for z/OS family to better detect performance problems in the cloud and minimize impact to the business and increase analytics visibility.
The new z/OS 2.1 operating system (mentioned earlier) enables the latest zEnterprise hardware features, including zEDC (Enterprise Data Compression) and SMC-R (Shared Memory Communications over RDMA – and that one stands for Remote Direct Memory Access). The so-called ‘Crypto as a Service’ enables Linux on System z applications to use z/OS services to encrypt data, thereby providing more secure encryption. Additionally, enhancements to z/OS Management Facility improve start up times and provides services for automating workflow, further reducing costs.
Of course, you may have missed IBM’s baby announcement because the news was swamped with Kate and William’s baby prince!

The Arcati Mainframe Yearbook 2013
The Arcati Mainframe Yearbook has been the de facto reference work for IT professionals working with z/OS (and its forerunner) systems since 2005. It includes an annual user survey, an up-to-date directory of vendors and consultants, a media guide, a strategy section with papers on mainframe trends and directions, a glossary of terminology, and a technical specification section. Each year, the Yearbook is downloaded by around 15,000 mainframe professionals. The current issue is still available at www.arcati.com/newyearbook12.
Very shortly, many mainframe professionals will receive an e-mail telling them that Mark Lillycrop and I have started work on the 2013 edition of the Arcati Mainframe Yearbook. If you don’t hear from us, then e-mail trevor@itech-ed.com and I will add you to our mailing list.
As in previous years, we’re inviting mainframe professionals to complete the annual user survey, which will shortly be up and running at www.arcati.com/usersurvey13. The more users who complete the survey, the more accurate and therefore useful the survey report will be. All respondents before Friday 7 December will receive a free PDF copy of the survey results on publication. The identity and company information of all respondents is treated in confidence and will never be divulged to third parties. And any comments made by respondents will be anonymized before publication. If you go to user group meetings, IOD, GCE Europe, etc, or just hang out with mainframers from other sites, please pass on the word about this survey. We’re hoping that this year’s user survey will be the most comprehensive survey ever. Current estimates suggest that there are somewhere between 6,000 and 8,000 companies using mainframes spread over 10,000 sites worldwide.
Anyone reading this who works for a vendor, consultant, or service provider, can ensure their company gets a free entry in the vendor directory section by completing the form, which will be at www.arcati.com/vendorentry. This form can also be used to amend last year’s entry.
Also, as in previous years, there is an opportunity for organizations to sponsor the Yearbook or take out a half-page advertisement. Half-page adverts (5.5in x 8.5in max landscape) cost $750 (UK£460). Sponsors get a full-page advert (11in x 8.5in) in the Yearbook; inclusion of a corporate paper in the Mainframe Strategy section of the Yearbook; a logo/link on the Yearbook download page on the Arcati Web site; and a brief text ad in the Yearbook publicity e-mails sent to users. All this for just $2200 (UK£1300).
To put that cost into perspective: for every dollar you spend on an advert, you reach around 20 mainframe professionals.

Making it look nice for CICS users
Let’s look at an archetypal MVS site. Kenny wrote most of the original Assembler and quite a bit of the COBOL code that drove the business all those years ago. He was a big man and a real hippie. He even came to work in his sandals and decorated his office with album covers. He thought that writing comments in code was just a waste of time. Doug, who took over from Kenny was an absolute troglodyte. Whereas Kenny was fun to go for a drink with – and boy could he drink – Doug was forever under the floor connecting high speed back-up technology that no-one else really understood. He was great because he’d help everyone with code problems, but he seldom turned up to meetings or understood the concept of budgets. But everything worked like a dream and the company made money.
Nowadays we’ve got Ross heading up software on our z/OS CICS system. He does attend meetings – lots of them. He’s on the committee at a local user group and he’s given presentations at SHARE. He’s even got a wife and children! The problem is that much of the code that Ross looks after is quite old and doesn’t have many comments. There was an effort in 1999 to document everything, but it’s now out-of-date since the SOA (Services-Oriented Architecture) project.
The trouble at many sites is that their Ross is kept very busy at the mainframe end of his CICS system and thinks that the bit of AJAX on the Web browser front-end is enough to keep the end users happy. The truth is, end users are never happy! So what if someone at a conference told Ross there was an easy way (well, perhaps not easy, but fairly straightforward certainly) to make the end user experience of his CICS applications look like it was written in 2012 and not 1912!?!? Do you think Ross would be interested?
Before we look at what this amazing solution might be, let’s briefly look at Web design. Back in 1999, a Web site was pretty much made up of static pages. Someone wrote the pages in HTML and, over time, people updated the information on those pages. Then we had PHP and MySQL. This provided a database that users could update as necessary, and the PHP pages pulled out the latest information. They still looked like static pages, but they were easier to update. Then, we had JavaScript that gave us programming capabilities and all the flexibility that goes with that. Then we had JQuery, which was JavaScript with all the hard work already done for us. You’ve seen Web sites with JQuery-like effects – the ability to click on a thumbnail image and see it large in the middle of the page while much of the rest of the screen is covered with a semi-transparent layer. An example would be clicking on a photo in Facebook.
So let’s tell Ross about the Dojo Toolkit from the Dojo Foundation. Now at Version 1.7, the Web site at http://dojotoolkit.org/ says: “Dojo saves you time and scales with your development process, using web standards as its platform. It’s the toolkit experienced developers turn to for building high quality desktop and mobile web applications.” Now, suppose there was some way to plug that into CICS. So while Ross was looking after the CICS applications, Dojo was making sure that the end users had a good experience.
The Virtual CICS user group (www.fundi.com/virtualcics/) heard from Stephen Mitchell, Managing Director of Matter of Fact Software Limited, earlier this month. He gave a talk entitled: “Utilizing the Dojo Toolkit for Web browser-driven applications from CICS”, which really got to grips with how CICS and the Dojo Toolkit could be integrated. The base functionality of the Dojo Toolkit is made available to a Web page by including a link to dojo.js. This includes plenty of features like CSS-based queries, event handling, animations, AJAX, class-based programming, and a package system that makes getting access to the rest of Dojo very easy.
There are additional stable (but optional) components for advanced animations, I/O, data, drag-and-drop, and much more with Dojo Core. Dijit is Dojo’s theme-able, accessible, easy-to-customize UI library. Dijit requires Dojo Base and various Dojo Core modules to use. It allows for the creation of widgets. For the more adventurous, there’s DojoX, which contains a number of sub-projects based on the Dojo Base. Each project has a varying states of maturity – from very stable and robust to alpha.
Stephen’s company recognized a need to control the Dojo Toolkit that was being used by their PlexSpy application status monitor product. And they decided that if it was an issue for them, it was most likely an issue for others. So they created a generic server solution that could be used by anyone with CICS on z/OS. As a consequence, the Dojo Toolkit has been taken into the mainframe environment and is served from CICS out of PDSs. This brings the strengths of the mainframe to sites using the Dojo Toolkit – providing the control over it that those sites needed.
Ross can now put his feet up at home with his family knowing that his end users are happy with their working environment. And the code Kenny and Doug wrote is still doing its job for another generation.

Linux divisions
Linus Torvalds released Linux on 5 October 1991, and by 1998 IBM was experimenting with it. In 2000 it was properly available on mainframes – along with the specialty processor IFL (Integrated Facility for Linux). The rest, as they say, is history.
As well as mainframes, Linux, of course, runs on desktops and servers. The Mac OS is based on Unix, but Android – found on millions of smartphones and tablets – is based on Linux.
So what divisions am I talking about? The division between big iron and little? Well not really. In fact, interestingly, the people at William Data Systems have come out with a way of monitoring Linux whether it’s on a mainframe or server somewhere else in the world. As long as it has an IP address, they have a way of monitoring it (using z/OS as the hub).
No, the first division I want to look at is the division between the USA (or North America, I should say) and Europe. The recent Arcati Mainframe Yearbook user survey (still freely available at www.arcati.com/newyearbook12) came up with some interesting results. The survey found that 70% of European sites surveyed didn't have Linux, whereas only 28% of North American sites in the surveyed didn’t. That’s a huge difference. And if you were IBM, you might well be wondering why Linux isn’t selling into Europe so well as North America.
Let’s speculate. Is it that North America is well ahead of the curve in terms of take up of mainframe Linux? Is it that mainframe Linux is priced differently either side of the pond so it encourages the take up in the USA but not Europe? Or could it be that IFLs are marked up or down depending on whether the customer is EMEA-based or not? Are IFLs being bundled in with upgrades or not depending on where in the world you’re based? I have recently had some nudges and winks over prices, and it could well be that European mainframe users are being charged double what their US-based counterpart might expect to pay. I’d be interested to hear what figure people, who’ve recently negotiated with IBM, have haggled them down to. You might also wonder whether now is a good time to buy shares in SuSE, who have about an 80% share of the mainframe Linux market. Will we see it suddenly explode in Europe? Or not?
The other division that’s recently cropped up with Linux is how users navigate. I guess we’re all pretty much familiar with using drop-down menus to access what we want – and we can probably use them to find our way around familiar applications without even thinking about it. Even very young childen take to that way of navigating like it was second nature. But just recently we’ve seen the introduction of Heads Up Displays (HUDs) for Ubuntu’s Linux.
What you get is a sort of semi-transparent area at the top of the screen, which acts in some ways like the ribbon with Office. HUD provides a search style interface that uses a Vocabulary UI (VUI). Users start to type or say a command, and the HUD starts a smart look-ahead search through the application and system (indicator) menus. By combining fuzzy matching with a learning function, the HUD begins to ‘recognize’ the actions of each individual user.
If you want to give it a go, HUD will be available in Ubuntu 12.04 towards the end of April.
Now I’m guessing that, like Microsoft’s ribbon, and Marmite, users will either love it or hate it. The idea that it will use voice indicates to me that we’re back to the original Star Trek computer idea – a computer that you can talk to. This was an idea that went away for a while because, to be honest, voice reconition software just wasn’t up to the job. But now we’ve had Siri on iPhones for a while, and people are coming back to the idea that talking to a computer isn’t such a silly idea after all.
I’ve only spoken to one person who’s used the HUD and he was singing its praises. But he is very familiar with Linux and the Ubuntu distro, so maybe he had a clearer idea of what to ask the HUD to do for him – in terms of getting any work done – than, for example, I might have.
Perhaps one day we’ll see a HUD on mainframe Linux. And perhaps we’ll see more mainframe Linux sites in Europe, Middle East, and Africa. Or will the divisions continue?

Sunk without trace
There was a time when using the trace facility was really the final strategy. You’d perhaps have tried everything else to find what was going wrong first. And when nothing seemed to have worked, you’d equip yourself with all the necessary manuals – and that could be quite a few – and run the trace and start the hard job of interpreting the results. And then try to fix the problem. Those days are long gone thanks to more modern software tools, but, to many people, the memories linger on!
I recently bumped into William Data Systems’ Tony Amies, who took the time to show me some of the things he was working on. And one of those things was making trace much, much, more user friendly.
Tony showed me WDS’s ZEN product, which, as you may know, allows lots of network monitoring information to be collated and viewed from anywhere using a browser. Information can appear as coloured boxes, which once you clicked on them display more-and-more information in a clever drill-down manner. Fairly quickly, you can identify the component that has exceeded some predetermined threshold.
WDS has a number of products in the ZEN family and you can use buttons on the browser to switch between them – giving you information about different aspects of performance. ZIM the ZEN IP MONITOR can detect error conditions, then ZEN TRACE and SOLVE (ZTS – which used to be called EXIGENCE) can be used to start, stop, and view traces. Now that has got to be so much easier than in the Old Days!
Tony showed how a TCP trace could be carried out in seconds, explaining that there were lots of commands embedded in it. Tony explained how network tracing can be so difficult. For example, using Enterprise Extender, which allows SNA applications to run over TCP networks, results in encapsulated messages. Tony demonstrated software that was able to look inside the message to see what was there – in terms of different types of header. He then explained how this works with FMH5, UDP, IP, APPN, HPR, and more. He explained that sites using the Cisco load balancing GRE tunnelling protocol can also be opened to see the true header for the message. All very clever stuff – and no manuals in sight.
In fact, on a number of occasions a right mouse click on some information in the display would produce a pop-up box explaining exactly what some term or other actually meant. So there was no need for any manuals. The display could show delays, highlight response time problems, and the TCP window size.
Tony also showed me a piece of software that drew a diagram of a Sysplex Distributor – which shows the IP addresses and links on a mainframe system. The software also highlighted where there were issues. And, like the rest of the software we looked at, you could drill down to find exactly where any problem were. In fact, Tony was sure that this would allow customers to identify potential issues before their users did. Behind the scenes, information from netstat and other commands were being used to drive the display.
We talked about customers being able to build business service views of what was going on their system and how useful that would be for each of their customers. That kind of bespoke requirement wasn’t something that Tony could necessarily build into the software, but all it requires is a knowledge of REXX to make it happen. And most z/OS sites have at least one person who code in REXX.
Lastly, we talked about problem resolution when you have two or more systems that don’t seem to be talking to each other. Currently, you need to log into each system and run traces to find out which of the systems has the problem. Tony plans to implement a ‘grouptrace’ feature that allows the user to tell the software to run a trace on these two (or more) systems. The results will come back from both systems and be visible from the browser. The results will be displayed in timestamp order and it will be possible to see on which of the systems the problem is. As easy that.
Too often we’d be sunk without a trace facility. Now we have an example of a way to be able to use trace across multiple systems and simply click to drill down to identify the problem.
I recently bumped into William Data Systems’ Tony Amies, who took the time to show me some of the things he was working on. And one of those things was making trace much, much, more user friendly.
Tony showed me WDS’s ZEN product, which, as you may know, allows lots of network monitoring information to be collated and viewed from anywhere using a browser. Information can appear as coloured boxes, which once you clicked on them display more-and-more information in a clever drill-down manner. Fairly quickly, you can identify the component that has exceeded some predetermined threshold.
WDS has a number of products in the ZEN family and you can use buttons on the browser to switch between them – giving you information about different aspects of performance. ZIM the ZEN IP MONITOR can detect error conditions, then ZEN TRACE and SOLVE (ZTS – which used to be called EXIGENCE) can be used to start, stop, and view traces. Now that has got to be so much easier than in the Old Days!
Tony showed how a TCP trace could be carried out in seconds, explaining that there were lots of commands embedded in it. Tony explained how network tracing can be so difficult. For example, using Enterprise Extender, which allows SNA applications to run over TCP networks, results in encapsulated messages. Tony demonstrated software that was able to look inside the message to see what was there – in terms of different types of header. He then explained how this works with FMH5, UDP, IP, APPN, HPR, and more. He explained that sites using the Cisco load balancing GRE tunnelling protocol can also be opened to see the true header for the message. All very clever stuff – and no manuals in sight.

What’s a mainframe, Daddy?
After years of sliding my security card in the lock and entering the machine room/data centre and seeing the mainframes in there change from Sci-Fi-style boxes with flashing lights to more mundane-looking boxes. From seeing simple DASD with less capacity than the memory stick in this laptop be replaced with cache controllers and more sophisticated data storage devices. It always seemed that there were plenty of mainframes around and any normal person (me) was constantly being offered tours round installations. So it comes as a bit of a shock when a youngster clearly has no idea what a mainframe looks like or what it does!
OK, no-one may have actually said those words as such, but that was the message. Plus, I was with some friends on Saturday when the conversation turned to discussing what use a mainframe was in this day and age! As Arcati Director, Mark Lillycrop, so eloquently put it recently, mainframes are thought of as ‘your dad’s technology’. Most of the people I was chatting to felt that mainframes were relics of the past and anything they can do, a few servers could do just as well!
So for many of us mainframe verterans, our job is to get out there and spread the word. We need to tell people exactly what a mainframe is, what it can do, and how people are interacting with them all the time, but don’t realise it. That way, the new generation of youngsters that are beginning to get access to mainframe technology at universities and elsewhere will arrive with a knowledge of what mainframes can do, and why working with them can be so enjoyable.
So let’s just start with the absolute beginner’s guide to mainframes. They are computers – just like your laptop – except that over the years they faced and solved all the problems about back-ups and restores, security, and high-speed data access. They have been around for a long time – which is a good thing because lots of people have moved the technology forward. They allow millions of users controlled access to information – allowing them to create, modify, and save data from almost any data entry device you can think of, including browsers.
Mainframes have been virtualized since the 1980s, and some of the software first saw the light of day in the 1960s. Most Windows data centres have only been virtualizing for the past five years! It’s true that laptops etc are everywhere – in your home, at work, etc – but mainframes are working away in the background. Everytime you take money from an ATM (cash machine) your bank is running a transaction on a mainframe. And it is banks and large financial institutions that use mainframes. And they do it because of the reliability. They do it because, should there be an outage, they can recover back to almost the last second before they went down. Almost no transactions are lost. And as a bank customer, I like that. Lots of non-mainframe-using sites think they are doing quite well if they can recover data back to last night! You see the difference in scale here.
Mainframes run an operating system (z/OS, but could be z/VM or z/VSE) and on top of that are a number of subsystems – you might think of them as apps (but big ones!). These subsystems include CICS and IMS. Now, both of these have been being developed since the 1960s and provide ways of accessing data very quickly and securely. They allow users to fill in virtual forms. And they store data in a way that means it can be accessed very quickly.
Another ‘app’ you may have heard of is DB2. DB2 is a comparative youngster, having arrived in the 1980s. It stores data in a ‘relational’ way rather than the more traditional ‘hierarchical’ way. DB2 is a database that can exist on Windows machines as well as mainframes (and many devices in between).
Mainframes can also run Linux (z/Linux) and all the Linux applications. That makes them very cost-effective replacements for sites with numerous ageing Linux servers. Linux has been available on mainframes for just over 10 years.
And there’s plenty of software available to control all aspects of this mainframe behemoth. And you can link them together at different sites in different countries round the globe.
So if anyone asks you what’s a mainframe, you can tell them that it’s the most successful server architecture ever devised and it’s all around them doing important work.

Blending mainframe technology with Apple, Blackberry, and Android – makes you think!
I don’t know whether you’re going to be at the SHARE conference in Anaheim (California) from 27 February to 4 March, but one of the interesting things to see is the William Data Systems stand (booth 211).
They are showing how their ZEN z/OS network management suite of product integrates with popular smart phone technology – Apple, Blackberry, and Android. What you’ll see is ZEN monitoring z/OS networks and then reporting the results to a mobile device. The user can then evaluate what’s happening on the mainframe and take appropriate action immediately. As a consequence, z/OS support staff can get on with their lives and be out and about, but still be able to monitor their mainframes and react to alerts.
The company say that this mobile technology extends ZEN’s whistle-blower ability to monitor SyslogD, filter the results by many criteria, launch automation commands or REXX procedures, and transmit the important alerts to mobile devices, all in real-time. I think this sounds pretty impressive and I was lucky enough to have a demonstration of the technology a few ago.
Originally the technology was restricted to iPhone and iPad users, but now it’s extended to the other ‘smart’ technologies that organizations use.
Their press release mentions SyslogD. In fact, this is probably the most useful resource that many IT departments ignore or only refer to long after they should. Having this kind of information on your phone seems almost futuristic.
Anyway, if you are at Anaheim, take a look.
On a completely different topic… I was pleased to receive the following e-mail during the week:
“On behalf of IBM, it is with great pleasure to recognize you as a 2011 IBM Information Champion. We would like to thank you for your leadership and contributions to the Data Management community. You continue to be among a very small group to be chosen for this recognition. Congratulations.”
This makes three years in a row.

IBM’s Transactional Analysis Workbench
Now I’m not here to tell you what software to buy and what to ignore, but if you haven’t had a look at IBM’s Transactional Analysis Workbench software yet, I think you should. It’s one of those pieces of software that kind of joins up the dots and allows you to see the bigger picture when you thought there was a performance problem. It can help identify performance issues in one subsystem – CICS, IMS, DB2, MQ, or even z/OS itself – when the symptoms of the problem are appearing in a completely different subsystem.
20 years ago, the world was a much simpler place. You’d be running IMS or CICS, and you’d be picking up data from your IMS database or DB2. But what was so simple, was the fact that the users of the data would be company employees. So, if there was a problem, you could use a fairly specific monitor to identify the location of the problem and fix it. Nowadays, you still run CICS and/or IMS as your transaction manager, but it can be linked to WebSphere MQ, and data can be coming from non-Z servers as well as IMS DB and DB2. But what makes life even more complicated is that the users are not just your staff, but also customers and potential customers, as well as automated systems that could be using your data in some mash-up appearing somewhere else entirely. Which means that it’s even more important to fix a slow-running system. And that means it’s vitally important to be able to quickly and easily identify where the problem actually is.
From a business perspective, there may be a single transaction that goes away, gets some data, and displays it. From a technical perspective, that single, say, CICS transaction may involve an IMS transaction running, and a DB2 intervention, and something involving MQ, before the results get back to the user’s screen. Now, if you think the problem lies with CICS, you can use CICS Performance Analyser to identify the problem. Or with IMS problems you can use IMS Performance Analyzer. Or for DB2 you can use DB2 Performance Manager, etc. But, what if the symptom appears to be IMS, but is really MQ? How can you combine this analysis to get to see the big picture of what’s happening on your system? This is where Transactional Analysis Workbench comes in.
You can check out the Web site to get all the specific details of why it’s a wonderful product, but I’d like to highlight just a couple of points. Transactional Analysis Workbench automated the collection of the data needed for problem analysis, and it provides a session manager to manage problem analysis through its life-cycle.
Rather cleverly, it allows slightly less-experienced or less highly-trained staff to identify the source of the problem. And then, when the ‘experts’ are available, it allows them to look in great detail to determine the problem. This is because the product links closely with other tools.
Transaction Analysis Workbench can provide a window into other subsystems that impact CICS and IMS performance. And by using information from SMF, OPERLOG, and other data sources such as CICS-DBCTL transaction performance, IMS address space resource consumption, WebSphere address space performance, MQ and DB2 external subsystem (ESAF) performance, APPC transaction performance, and IRLM long-lock activity, it can give an insight into what’s changed and where the problem might be originating.
Joined up software has got to be a good thing. And a product that can link closely with more specific monitoring or analysis tools has got to be a great help in finding out what’s different today compared to yesterday that’s causing a sudden drop in performance. But take a look yourselves.

The importance of mainframe performance
It’s so easy to forget, or just take it as read, that mainframes have been able to successfully run with five nines availability for well over a decade. What that means is achieving 99.999% of scheduled uptime. In other words, it means that unscheduled downtime is less than five and half minutes in a year! Now that kind of amazing performance is something that boxes running other operating systems can only dream of. Some are working towards that level of availability, but others (you know who I’m thinking of here) aren’t even close.
But I wasn’t thinking about performance in that sense. We just take it for granted the operating system is going to be always working. What I was thinking about was the performance of the major subsystems running under z/OS. It’s very important to take steps to ensure that CICS or IMS are performing optimally. Monitoring software can be installed that will identify when preset thresholds are reached. They help identify bottlenecks and then the appropriate action can be taken to resolve them. This is the kind of stuff systems programmers have been working away at for years. They’ve been using faster processors, faster I/O, more efficiently-coded transactions, until every component is working as well as it can.
In previous blogs, we’ve talked about monitoring software that can arrange for alerts to be sent to designated staff as text messages or e-mails – allowing them to access the nearest iPad or laptop and take steps to resolve the new problem.
As well as CICS and IMS, there are monitors for DB2, WebSphere, and z/OS itself. These can all be integrated and produce wonderful moving graphs or other displays that allow users to tell at a glance whether everything is OK or whether a slight tweak to the subsystem is required. In addition, we’ve had software that learns how to maintain high performance and make appropriate changes on-the-fly, without any human intervention.
But the problem that many sites now face is what they can do if, for example, IMS users are reporting slow response times, but the problem appears to be coming from outside the IMS subsystem rather than from inside it. For example, what appears to be an IMS performance problem could be a CICS, DB2, WebSphere, or z/OS performance problem. The challenge facing systems programmers in this situation is to correlate performance data in IMS with activities in these other systems in order to discover the cause of the slow response time.
One new solution is Transaction Analysis Workbench, which is an IMS tool. If you’re interested in how to approach this type of situation, how to gather the necessary information from multiple subsystems, and then analyse, diagnose, and resolve the problem, you’ll be interested in the webinar from the Virtual IMS user group this week.
The Virtual IMS user group runs free webinars every other month. During the webinar, a technical expert shares their hard-won knowledge with the rest of the group. The webinars use Citrix GoToMeeting, which means you don’t have to face the hard task of convincing your company to fund your user group experience – you just sit down at your laptop and log in.
Anyone wishing to join the webinar needs to join the user group – which is also free. The next meeting is at 10:30 Central Standard Time on Tuesday 8 February. The user group’s Web site (where you can join) is at www.fundi.com/virtualims.

2010 mainframe review
As this will probably be my last blog of 2010, I thought it would be traditional to review what’s happened in the mainframe world over the past year.
2010 will probably be remembered as the year of the cloud because it was the year when cloud computing started to be taken seriously across the industry. Microsoft opened its ‘mega data centre’ in Dublin and promoted its Windows Azure environment for development, service hosting, and service management based on the cloud. Google worked with VMware to develop a new operating system for the cloud, and launched a version of the Google App Engine for enterprise users. Amazon promoted its Elastic Compute Cloud (Amazon EC2) service. And many people suggested that mainframes have offered cloud computing all along – we just called it something else!
IBM’s acquisitions this year include: National Interest Security Company, Initiate Systems, Intelliden, Cast Iron Systems, Sterling Commerce, Coremetrics, BigFix, Storwize, Datacap, Unica, OpenPages, Netezza , PSS Systems, and Clarity Systems.
The big story of 2010, of course, was the launch of a new mainframe range in July. The zEnterprise 196 brings together the latest mainframe technology with POWER7 and x86 IBM blade systems, giving potential users z/OS, AIX, and Linux all on the one box. And all this is controlled from the mainframe console by the new Unified Resource Manager. This new mainframe can be thought of as a virtualization hub that manages other workloads in the data centre.
For people who like to stay current with the latest version numbers and dates of major products, CICS 2.1 has been available since the middle of 2009, DB2 10 was announced earlier this year, as was z/OS 1.12, and IMS 12 should be generally available early in the New Year.
The battle between IBM and NEON Enterprise Software (provider of the zPrime product, which allows users to run traditional workloads on specialty processors) has rumbled on in the courts for a year without any sign of an outcome. The European Union regulators have taken IBM to task for not allowing its operating system to run on other hardware, and for not being fair to so-called ‘spare-part’ vendors. The first complaint came from T3 and TurboHercules, saying that IBM ties its mainframe operating system to its mainframe hardware – and thereby destroys the emulation market.
For me and iTech-Ed Ltd it was a good year. I was given the accolade of IBM Information Champion again this year. My blog at Mainframe Update (mainframeupdate.blogspot.com) was again a finalist in the Computer Weekly annual blog awards. I was interviewed by CIPS (the Canadian Information technology Professionals). You can download a podcast of the interview from the CIPS Connections site at stephenibaraki.com/cips/v610/trevor_eddolls_2010.html. I was invited by CA to be on their expert panel for a webinar called “From Here to Eternity: The Mainframe as a Mainstay of the Enterprise” discussing cloud computing. Other panellists were Jon Toigo, CEO, Toigo Partners International; Keith Winnard, IT technical services, JD Williams; and Dayton Semerjian, general manager, mainframe, CA Technologies; and control of the session was maintained by Michael Krieger. iTech-Ed helped produce the Arcati Mainframe Yearbook 2010, which is still available for download from www.arcati.com/newyearbook10. The 2011 edition will be available in January. IBM Systems Magazine's Mainframe Extra eNewsletter was quite taken by one of my regular blogs and they included it in their "Links We Love" section. My articles on cloud computing and IMS was published in the October/November issue of zJournal. The links for the articles are www.mainframezone.com/it-management/ims-and-cloud-computing and www.mainframezone.com/it-management/sidebar-cloud-computing-origins-and-evolution. Exciting things are happening with the Virtual IMS user group that iTech-Ed runs. After a short hiatus, a new sponsor for the user group has been found and webinars and newsletters will continue for members and guests in the New Year. Look out for more details.

Amazon promoted its Elastic Compute Cloud (Amazon EC2) service. And many people suggested that mainframes have offered cloud computing all along – we just called it something else!
IBM’s acquisitions this year include: National Interest Security Company, Initiate Systems, Intelliden, Cast Iron Systems, Sterling Commerce, Coremetrics, BigFix, Storwize, Datacap, Unica, OpenPages, Netezza , PSS Systems, and Clarity Systems.
The big story of 2010, of course, was the launch of a new mainframe range in July. The zEnterprise 196 brings together the latest mainframe technology with POWER7 and x86 IBM blade systems, giving potential users z/OS, AIX, and Linux all on the one box. And all this is controlled from the mainframe console by the new Unified Resource Manager. This new mainframe can be thought of as a virtualization hub that manages other workloads in the data centre.
For people who like to stay current with the latest version numbers and dates of major products, CICS 2.1 has been available since the middle of 2009, DB2 10 was announced earlier this year, as was z/OS 1.12, and IMS 12 should be generally available early in the New Year.
The battle between IBM and NEON Enterprise Software (provider of the zPrime product, which allows users to run traditional workloads on specialty processors) has rumbled on in the courts for a year without any sign of an outcome. The European Union regulators have taken IBM to task for not allowing its operating system to run on other hardware, and for not being fair to so-called ‘spare-part’ vendors. The first complaint came from T3 and TurboHercules, saying that IBM ties its mainframe operating system to its mainframe hardware – and thereby destroys the emulation market.
For me and iTech-Ed Ltd it was a good year. I was given the accolade of IBM Information Champion again this year. My blog at Mainframe Update (mainframeupdate.blogspot.com) was again a finalist in the Computer Weekly annual blog awards. I was interviewed by CIPS (the Canadian Information technology Professionals). You can download a podcast of the interview from the CIPS Connections site at stephenibaraki.com/cips/v610/trevor_eddolls_2010.html. I was invited by CA to be on their expert panel for a webinar called “From Here to Eternity: The Mainframe as a Mainstay of the Enterprise” discussing cloud computing. Other panellists were Jon Toigo, CEO, Toigo Partners International; Keith Winnard, IT technical services, JD Williams; and Dayton Semerjian, general manager, mainframe, CA Technologies; and control of the session was maintained by Michael Krieger. iTech-Ed helped produce the Arcati Mainframe Yearbook 2010, which is still available for download from www.arcati.com/newyearbook10. The 2011 edition will be available in January. IBM Systems Magazine's Mainframe Extra eNewsletter was quite taken by one of my regular blogs and they included it in their "Links We Love" section. My articles on cloud computing and IMS was published in the October/November issue of zJournal. The links for the articles are www.mainframezone.com/it-management/ims-and-cloud-computing and www.mainframezone.com/it-management/sidebar-cloud-computing-origins-and-evolution. Exciting things are happening with the Virtual IMS user group that iTech-Ed runs. After a short hiatus, a new sponsor for the user group has been found and webinars and newsletters will continue for members and guests in the New Year. Look out for more details.
Merry Christmas and a happy New Year.

Who cares about SyslogD on a mainframe?
Unix System Services (USS) on a mainframe basically allows Unix applications to run and communicate. Running under USS is Syslog Daemon or SyslogD. This is an important system component because it’s part of z/OS’s Intrusion Detection and prevention Services (IDS). SyslogD receives detailed event messages, such as security violations, as well as messages from many other communications services such as FTP and AT-TLS, plus messages from routers, switches, and other network-based devices.
So, in the event of a hacker trying to log-on to your mainframe, how would you know? And when would you know? Surprisingly, many sites appear to ignore the information written to SyslogD completely! While other sites look at what has happened, perhaps a minute ago, perhaps an hour ago, perhaps yesterday!
What you probably need is some way to be alerted about what’s happening now. And, as this is 2010, you probably want the alert to come through to your mobile phone. And you then want to be able to jump on any browser, see where the trouble lies, and fix it. What are the chances of there being software that does that?
Well, let me confirm that it does exist and I’ve seen it.
WDS (www.willdata.com) has rather nice mainframe-based HTTP server software that front-ends their mainframe monitoring products. It’s called ZEN and it allows users of their products to access information through a browser – almost any browser. Their products are called ZEN EE Security, ZEN IP Monitor, or similar, but are perhaps better known by their old names of Ferret, Implex, etc. The products can monitor APPN, EE, FTP, IP, SNA, OSA, and USS. Each of these programs effectively has a DLL that allows them to plug in to the HTTP server. This can then respond to messages by ignoring them, sending a command, running a REXX EXEC, or sending an e-mail. It’s completely automated and configurable to what the users want. ZEN can also run utilities such as PING, TRACEROUTE, and NSLOOKUP commands. And, in addition to input from WDS’s programs and SyslogD, it also receives network messages and ECMS console contents.
For the end user, working from a browser, windows can be opened and closed, resized, refreshed, whatever. The windows can show number data and regularly-updated graphical displays. In fact, a variety of different graphs can be monitored in different windows at the same time, allowing end-users to monitor what’s going on in real-time. The drawing of the graphs is all handled in JavaScript (JSON, in fact), and AJAX is used so only the parts of the display that change are sent from the server to the browser, which speeds up communication considerably. It’s possible to drill-down through the alert information on screen, for example, to one particular type of alert, on a particular day, during a particular time range.
Now, the type of display I want on, say, a 17 inch laptop screen is not the same as on a 3 inch smart phone screen. You might think this would be a bit of a fly in the ointment. The truth is that WDS has a solution to even this problem.
Looking to the future, what else could we ask them to do with their excellent end-user interface? Might it not make sense to automate the monitoring of other things and use the browser-based interface to see what’s going on? Is there a way this could be done for, say, other Linux boxes? We’ll have to wait and see.
But whatever software monitor you choose, and however you choose to display it, it makes sense to ensure that SyslogD is not being ignored.

Managing mainframes from your phone
William Data Systems has come up with a clever way of managing your mainframe network from an iPhone. Now as soon as you see the word iPhone, you probably think it’s an app and you’re going to have to get all your users synchronizing with iTunes before they can use it or update it. The truth is, it’s a much cleverer idea than that!
Let’s start at the beginning, WDS (William Data Systems) has a z/OS network management suite called ZEN, which has a number of really useful components that you can find out more about from their Web site (www.willdata.com). Their customers wanted an easy way to keep up-to-date with what was happening with their networks. And one thing everyone has these days is a mobile (cell) phone – so why not come up with a way of monitoring the network from your phone?
What WDS did, was to utilize the browser on iPhones – Safari, the same one that comes as standard on Macs – and allow users to monitor and manage their mainframe networks from there.
Now because Safari is an integral part of the iPhone, the technology works for all iPhone users. As I said at the beginning, there’s no problem of resynchronizing every user by getting them to plug their phones into iTunes. There’s no fuss about accessing the App Store. It’s all there on the browser.
As more-and-more companies are asking for z/OS network monitoring and management to be done remotely when needed using a single mobile device that support people would be carrying with them, this solution seems to tick all the boxes. If a problem is found, then the techie can find a laptop and fix it, or use the phone to call the service centre and get someone there to fix it. Either way, the problem is solved, perhaps before users have begun to notice. Interestingly, the solution can be used from an iPad. In that case, the screen is big enough for a techie to actually use instead of a laptop – and solve the problem immediately.
What if your organization doesn’t use iPhones? What if you’ve rolled out Blackberrys? Well in that case, WDS has a solution available. If your organization uses Symbian or Android (or anything else), then WDS are developing a solution for your smart phone right now.
It may all seems like something from a 1990s sci fi film, but monitoring your z/OS network from your mobile phone is a solution that’s available now.
And finally, as a mainframe professional, I am hoping that you will be willing to complete the annual user survey at www.arcati.com/usersurvey11. If the company you work for is a vendor, consultant, or service provider, then please ensure their information is included in the vendor information form at www.arcati.com/vendorentry.

The Arcati Mainframe Yearbook 2011
The Arcati Mainframe Yearbook has been the de facto reference work for IT professionals working with z/OS (and its forerunner) systems since 2005. It includes an annual user survey, an up-to-date directory of vendors and consultants, a media guide, a strategy section with papers on mainframe trends and directions, a glossary of terminology, and a technical specification section. Each year, the Yearbook is downloaded by around 15,000 mainframe professionals. The current issue is still available at www.arcati.com/newyearbook10.
Very shortly, many of you will receive an e-mail informing you that Mark Lillycrop and I have started work on the 2011 edition of the Arcati Mainframe Yearbook. If you don’t get an e-mail from me about it, then e-mail trevor@itech-ed.com and I will add you to our mailing list.
We’re hoping that mainframe professionals will be willing to complete the annual user survey, which will shortly be up and running at www.arcati.com/usersurvey11. The more users who fill it in, the more accurate and therefore useful the survey report will be. All respondents before Friday 3 December will receive a PDF copy of the survey results on publication. The identity and company information of all respondents is treated in confidence and will never be divulged to third parties. If you go to user group meetings, or just hang out with mainframers from other sites, please pass on the word about this survey. We’re hoping that this year’s user survey will be the most comprehensive survey ever. Current estimates suggest that there are somewhere between 6,000 and 8,000 companies using mainframes spread over 10,000 sites.
Anyone reading this who works for a vendor, consultant, or service provider, can ensure their company gets a free entry in the vendor directory section by completing the form at www.arcati.com/vendorentry. This form can also be used to amend last year’s entry.
As in previous years, there is the opportunity for organizations to sponsor the Yearbook or take out a half page advertisement. Half-page adverts (5.5in x 8in max landscape) cost $650 (UK£390). Sponsors get a full-page advert (11in x 8in) in the Yearbook; inclusion of a corporate paper in the Mainframe Strategy section of the Yearbook; a logo/link on the Yearbook download page on the Arcati Web site; and a brief text ad in the Yearbook publicity e-mails sent to users. Price $1900 (UK£990).
To put that cost into perspective, for every dollar you spend on an advert you reach around 25 mainframe professionals.
The Arcati Mainframe Yearbook 2011 will be freely available for download early in January next year.

z11, zNext, zEnterprise System, zWOW!
Even though everyone’s signed non-disclosure agreements, there’s lots of buzz about IBM’s latest mainframe announcement. We thought it would be called the z11, but now we think it will be zNext or zEnterprise System, but whatever it’s called, when it’s announced on the 22 July (the date everyone’s guessing), people are going to say, “Wow!”
Why wow? Well the rumours suggest that this new “mainframe” is going to be a giant step into the future. Not only will the box run z/OS on its 5.2GHz quad-core z processor, but also AIX on Power 7 blades and Linux on x86 blades – all in the same box, and all sharing memory and disk space. Have you said “wow” yet? Well how about this? The multiple OSes will, allegedly, function as one single, logical, virtualized system!
So, although everything is more secretive than a new iPhone launch (although no-one has left a mainframe behind them in a public toilet!), we’ll publish more information as it becomes available.

Change is the only constant!
“Any change, even a change for the better, is always accompanied by drawbacks and discomforts.” So said Arnold Bennett the novelist, playwright, critic, and essayist, who lived from 1867 to 1931. Winston Churchill’s take on the subject was: “There is nothing wrong with change, if it is in the right direction”. And Harold Wilson, who was also a British Prime Minister said: “He who rejects change is the architect of decay.”
This week I want to talk a little bit about change – or, more particularly, change management. We’re all so use to change these days we perhaps forget that there are ways of carrying out change in an organization that work – and, of course, ways of performing change that lead simply to chaos! There’s hardly a new leader, whether in government or within an organization that doesn’t feel making a few changes will stamp his or her mark on that organization (or country or whatever).
So what is change management? Well, Wikipedia informs us that: “change management is a structured approach to transitioning individuals, teams, and organizations from a current state to a desired future state. Change management (or change control) is the process during which the changes to a system are implemented in a controlled manner by following a pre-defined framework/model with, to some extent, reasonable modifications.”
In terms of mainframes, you might be looking at products such as the CA Endevor or ChangeMan. The CA Web site tells us: “CA Endevor Software Change Manager automates your entire development process, adapting to specific business requirements while ensuring consistency and complete control, protecting your software assets, and maintaining application integrity”. Integration with IBM Rational Developer for System z improves productivity, accelerates time-to-delivery, and ensures the auditability of all programmer activities. Serena’s Web site says: “Serena ChangeMan ZMF, Change Management for Mainframe Systems, protects your corporate assets – and in the process, lets your programmers get more done in less time. Serena ChangeMan ZMF controls every code change in your mainframe environment. It guarantees source-to-load integrity and ensures that only successfully tested programs make it into production. ChangeMan ZMF reduces maintenance costs and regression errors by moving code through an automated mainframe life-cycle with strict accountability and quality assurance at every step. It can support developer communication and perform regression analyses as part of the most thorough concurrent development available. With ChangeMan ZMF, application code is easier to find, modify, and deploy.”
Many of the change management products that Google can find claim to adopt ITIL (Information Technology Infrastructure Library) models. ITIL, as I’m sure you know, provides a source of best practice for a range of IT tasks. It claims on its Web site to be: “the only consistent and comprehensive documentation of best practice for IT Service Management. Used by thousands of organizations around the world, a whole ITIL philosophy has grown up around the guidance contained within the ITIL books and the supporting professional qualification scheme.”
But suppose you’re looking for a Software Change Management (SCM) product, a version and release management tool for the enterprise, and an application deployment tool not just for the mainframe but also for your distributed platforms. The choice is usually to buy three pieces of software. Interestingly, ISPW – the organization, www.ispw.com – has a product called ISPW that does just that.
On their Web site, they inform us that: “ISPW is a DB2-based all-in-one SCM solution that manages z/OS and distributed applications in one seamless solution. It has a z/OS based server and three thin-client interfaces:

- A traditional 3270 interface for mainframe developers
- A browser for supervisors and approvers
- An Eclipse-based client for mainframe and distributed users.
User friendliness and productivity are ISPW strengths, along with a unique tools integration capability.”
I also discovered at the beginning of the month that ISPW has partnered with RSM to market and support the product in the UK. The press release also says about ISPW (the product that is): “ISPW allows programmers to work from their platform of choice and eliminate many common sources of error in the process. Advantages for complex IT installations include:

- Automatic inclusion in corporate disaster recovery processes
- Improved project management through early conflict resolution and comprehensive visibility

Which all seems to make ISPW an interesting product, and well worth a second look.

If you have to ask the price, you can’t afford it!
So how much does a z10 processor cost? If I want to install IMS in two z/OS partitions, how much is that? How much do most people pay for MIPS usage? How long is a piece of string?
Going to the supermarket is easy, everything has a price marked on it. Purchasing off the Internet is straightforward, you find the item with the lowest price and with the lowest delivery charge. But buying a mainframe is perhaps more than bit like buying a used car from some of the slickest salespeople in the world. What can you do to tip the balance? How can you, as a potential software or hardware purchaser, put yourself in a stronger bargaining position.
One solution for people in the UK and Europe is to attend Arcati’s annual seminar on mainframe pricing and contract negotiation, which takes place on 28th June 2010 at the Premier Inn Touchbase Centre, London Heathrow. As always, the principal speaker is Barry Graham, an internationally-recognized authority on mainframe pricing issues. Working with Barry, users with as few as 600MIPS and as much as 100,000MIPS have, they claim, signed contracts saving up to 30% of their expected spend.
In addition, David Wilson, an independent consultant and former IBM senior executive for System z software in North East Europe, will be looking at what users should do to maximize the benefits of their current mainframe installations.
Sessions at the seminar include:

- Putting software costs in context
- New pricing models and future costs
- Negotiating an IBM ESSO or ELA contract
- Maximising the benefit of mainframes
- Hardware pricing update.
The programme covers pricing for all z10 Enterprise and Business Class systems, and also includes a discussion of Passport Advantage, Processor Value Units, and their effect on software price/performance.
If this is something that interests you, then you can get full details on the Arcati Web site at http://www.arcati.com/mmevent10. They also offer an on-going Mainframe Market Information Service, covering similar issues. You can find out more details about that from http://www.arcati.com/mmis.
Anything that helps bring down the cost of mainframe computing – from a user’s perspective – has got to be a good thing.

What's going on - on my Open Systems Adapter?
An Open Systems Adapter (OSA) is a network controller between mainframes and other computing platforms. An OSA supports Ethernet, Token Ring, and FDDI (Fibre Distributed Data Interface) connectivity, and can offer data throughput speeds of up to 10 gigabits per second. An OSA provides a way of attaching a LAN (Local Area Network) to a mainframe, or looking at it the other way round, it provides a way of connecting a mainframe to a LAN! Either way, it makes it a very crucial piece of kit.
At most installations, life isn't quite so simplistic. For example, a single OSA can be shared across several LPARs and/or IP stacks. It can handle multiple channels and multiple types and instances of ports. And the consequence of this is its ability to support a very large number of users.
You'd think this kind of complexity would make the OSA a device that is monitored by every site that's got one. After all, what would happen were it to suddenly stop working? But the complexity doesn't stop there. An OSA exists as a z/OS device, a VTAM device, an IP interface, and an SNMP device. And it's this level of complexity that makes the collection of data so tricky. There's not even some low-level tool providing a single query that will reveal how an OSA is performing.
In truth, OSAs are resilient, managing to recover and log any non-fatal errors encountered in an internal Management Information Base (MIB). The MIB is a database containing information about the current OSA set-up and state information. Getting information out of the MIB is only possible with low-level tools and a good knowledge of the associated MIB structures. An OSA MIB may well contain many thousands of separate fields identified by Object Id and an Index relating them to a specific LPAR, channel, or port. Additional information about an OSA can be found in z/OS device tables, IP stacks, and VTAM control blocks.
Perhaps surprisingly, many sites feel that an IP monitor is probably all that's needed to keep an eye on their OSA. However, a new alternative is ZEN OSA Monitor (ZOM) from William Data Systems (www.willdata.com). ZOM provides users with the ability to get a health check of their OSA, and it also provides a soft reset feature. According to the WDS Web site: "ZOM dynamically detects any status changes or increases in error counts, with all such changes summarized in easy-to-read panels in ZEN, with full alerting and reporting capabilities. A simple but effective system of traffic lights highlight any changes to reference values, ensuring these critical devices are maintained at optimal performance levels."
Some readers may be familiar William Data Systems ZEN EE (Enterprise Extender) Monitor, codenamed Ferret.
With ZOM, the OSA dashboard provides an at-a-glance list of a user's monitored OSAs with an indication of current usage and status. Several fields contain drill-down links to further, more detailed displays.
With OSA devices playing such a critical role in the communication between mainframes and the rest of the computing environment, it would make sense to utilize a product that's able to access important performance data and display it in an easily digestible format. Anyway, they're not paying me to sell their product for them, but I thought readers of this blog would find the existence of this software well worth knowing about.

DB2 V10 for z/OS beta
IBM has recently announced a beta of DB2 Version 10. It's claimed to provide savings through operational efficiencies, resiliency for business critical information, rapid application and warehouse deployment for growth, and enhanced query and reporting facilities.
IBM claims that compared to previous DB2 versions, some customers can achieve a 5% to 10% out-of-the-box CPU savings for traditional workloads and up to 20% out-of-the-box CPU savings for non-traditional workloads. IBM also suggests that productivity improvements in DB2 10 for database and system administrators can drive additional operational efficiencies and cost savings. Synergy with other System z platform components reduces CPU use by leveraging the latest processor improvements, larger amounts of memory, solid-state disk and z/OS enhancements.
In terms of scalability, DB2 10 delivers the ability to handle up to 20,000 concurrent active users on a single DB2 subsystem, many more than in previous versions. SQL and pureXML enhancements in DB2 10 help extend usability, improve performance, and ease application portability to DB2 for z/OS.
IBM goes on to say that built-in data visualizations and graphical page-based reports extend Query Management Facility (QMF) 10's usage from the traditional technical user to a broader community of business end users. QMF's new metadata layer, they say, simplifies the underlying data model, empowering non-technical users with self-service reporting and extends access to DB2 for z/OS across the enterprise.

2009 – a review
2009 was quite an interesting year considering that we entered it in the middle of the worst financial crisis for x number of years – I’ll leave you to fill in a value for ‘x’, but whatever number you put, things were bad.
So, what exciting things did happen? Well, IBM continued with the inexorable progress of its mainframe software. We saw IMS V11 actually being GAed – it had been available as a beta for a while. The new version boasted even better SOA (Service-Oriented Architecture) and Java features and a host of other useful enhancements for IMS users.
The people at Hursley gave us CICS/TS Version 4.1. This again had robust all-round improvements plus featured enhancements in the areas of Web 2.0, dashboards, and business event publishing.
DB2 didn’t exactly manage a new release proper, but did beta Version 10. Again, this is designed to improve performance and save MIPS – which being chargeable is a good thing to have. Obviously someone at IBM owns a Mac rather than a PC because they are calling it DB2 X (like Mac OS X).
Perhaps the most important release is the new version of the operating system. The cool kids are now using z/OS V1.11. Like all good operating system upgrades it is backwards compatible and improves performance. There were also some enhancements to autonomic computing – the software answer to the ageing IT population – which means the software will identify potential faults before they occur and take steps to prevent them. Or if it’s too late for that, they will recover from them – and all without human intervention.
Away from the mainframe, perhaps the biggest news was Oracle buying Sun Microsystems. Reports are coming in of potential massive job cuts at Sun. Interestingly, Michael ‘Monty’ Widenius, co-creator of MySQL (which Sun owns), ran a Web campaign called “Save MySQL” to convince European regulators to prevent Oracle’s buyout.
The other big news for mainframers was NEON Enterprise Software’s announcement of zPrime. Why the excitement? Well, IBM and many independent software vendors (ISVs) generally charge users for software by the amount of General Purpose Processor (GPP) capacity they use. IBM also sells specialty processors, which are available for workloads like Linux, Java (think WebSphere), and DB2. For a typical mainframe site, processing work in a specialty processor saves money because it is not using the chargeable GPPs – and there’s an added benefit that it can save an organization money by putting off the need for an expensive processor upgrade. The controversial zPrime software, according to NEON, allows users to run up to 50% of their workload on specialty processors. So in effect a zIIP doesn’t just run DB2 work, it can also run IMS, CICS, TSO/ISPF, batch, etc, etc. On the plus side this offers the strong possibility of bringing down the total cost of ownership of the mainframe, which is always good for users (though there is some debate about the achievable level of savings). On the negative side, IBM and ISVs may opt to limit the use of zPrime through licence changes (particularly for those users who are tied into Enterprise Licence Agreements) if specialty processors are used for workloads other than those intended. IBM has already issued letters about customers violating agreements if they use zPrime, and NEON has sued IBM. It will be interesting to see what happens in 2010.
Personally, 2009 was an interesting year. I became an IBM Data Champion in an IBM-sponsored initiative that was rebadged as IBM Information Champions. I was also a finalist in the Computer Weekly blog awards in the category of Individual IT professional male. In addition, I qualified as a clinical hypnotherapist and psychotherapist and added loads of letters after my name. (If you want to know, look at http://www.itech-ed.com/hypno/us.htmhttp://www.itech-ed.com/hypno/us.htm.)
Looking forward to 2010, the Arcati Mainframe Yearbook will be available shortly with its annual mainframe user survey; the Virtual IMS Connection user group has a full calendar of events for IMS users; you can now follow my IT-related tweets on Twitter (twitter.com/t_eddolls), and become a fan of iTech-Ed on Facebook. It will be interesting to see what else happens.
