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.

Arcati Mainframe Yearbook 2011 user survey

The Arcati Mainframe Yearbook 2011 has been available for download free from www.arcati.com/newyearbook11 for nearly a month now. Each new Yearbook is always greeted with enthusiasm by mainframers everywhere because it is such a unique source of information. And each year, many people find the results of the user survey especially interesting.

The 100 respondents who completed the survey on the Arcati site did so between 1 November and 3 December 2010. 32% were from Europe and 52% from North America, with 16% from the rest of the world.

44% of the respondents worked in companies with upwards of 10,000 employees worldwide, while 14% of respondents had 0-200 staff, 10% had 201-1000, 14% had 1001 to 5000, and 14% had 5001-10,000 staff. In terms of MIPS, 50% of respondents had fewer than 1000 MIPS installed, 24% fell into the mid-sized category between 1000 and 10,000 MIPS, and 22% were at the high end.

Looking at MIPS growth produced some interesting results. Larger, more mature businesses (above 10,000 MIPS) were almost all experiencing some growth, but predominantly in 0 to 10% per year category. Sites in the 1000-10,000 MIPS range were showing a range of results with some sites suggesting a decline while others predicted growth in excess of 50%. Sites below 1000 MIPS were most likely to be experiencing growth of less than 10%, with the largest percentage (of these three groups) predicting a decline. The mainframe market does appear to be quite fragmented with competitive pressures at the lower end of the mainframe market, and some respondents commented about lack of understanding amongst management about the value of mainframe computing.

With the environment and environmental issues getting so much coverage in the media these days, the survey asked whether IBM’s recent green initiatives on things like power consumption and cooling had made the mainframe more or less attractive. Nearly three-quarters (72% – the same as the previous year) said that IBM’s green initiatives made no difference at all. 17% felt it made the mainframe a little more attractive, and 11% felt it made the mainframe a lot more attractive. Clearly “greenness” isn’t much of a selling point for mainframes.

With so much talk about Cloud Computing, for the first time the survey asked the mainframe population for their opinion. It asked whether respondents currently used their mainframe for cloud computing. Only 2% of respondents said they did. 34% said they didn’t, and the rest weren’t sure. Bearing in mind that it is still early days for a cloud computing initiative, the survey asked whether respondents were planning to adopt cloud computing as a strategy. 22% said they weren’t at present. 8% thought some mainframe applications would be cloud-enabled in the future, and a similar number thought most would be cloud-enabled in the future. However, 4% didn’t see a use for cloud computing. It will be interesting to follow these figures in future surveys.

The survey asked respondents which specialty processors (IFL, zIIP, and zAAP) they had. 6% of sites had all three (down from last year’s value of 12%) and a further 28% of sites had two of the three specialty processors (up from last year’s 12%). More sites had zIIP processors (44%) than any other. 36% had IFL processors, and 24% had zAAP specialty processors. 36% of sites don’t have a specialty processor installed.

It seems that at many sites, mainframes are losing out due to management ignorance. The survey quotes one respondent who said: “We do not expect to have a mainframe within 2-3 years. The CIO sees the mainframe as obsolete and expensive, whether or not either of those is true”. Another respondent complained: “Our architects do not understand mainframes and seem to be mostly knowledgeable about Windows. Project funding is project based and not enterprise based, hence a tendency to prefer perceived cheaper solutions, eg Windows.”

The appearance of the z196 processor had a big impact within the industry. High-profile TV appearances of Watson on Jeopardy keep people familiar with the name IBM. However, there is still a lack of understanding of what a mainframe does and what it can do amongst far too many IT managers and other corporate executives.

Anyway, full details of the responses to many other questions can be found in the user survey section of the Yearbook. It’s well worth a read.

The Yearbook can only be free to mainframers because of the support given by sponsors. This year’s sponsors were CA Technologies, Canam Software, DataKinetics, and Type80 Security Software.

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.

The Arcati Mainframe Yearbook 2011 - now available

Every year, about this time, we welcome a new edition of the Arcati Mainframe Yearbook. It really is the standard reference work for all IBM mainframe professionals – whether they’re grizzled old-timers nearing retirement or that new batch of recently graduated enthusiasts, and everyone in between.

Why is it such an important publication each year? The simple answer is that it provides a one-stop shop for everything you need to know. For newcomers (and people moving to an area slightly outside their comfort zone) there’s a technical specification section that includes model numbers, MIPS, and MSUs for z196 and z10 processors. There’s a hardware timeline, and a display of mainframe operating system evolution. In addition, there’s the glossary of terminology section explaining simply what those acronyms mean.

One section provides a media guide for IBM mainframers. This includes information on newsletters, magazines, user groups, and social networking information resources for the z/OS environment. Amongst the things it highlights are zJournal, INSIGHT-SPECTRA, IBM Listservs, SHARE’s Five Minute Briefing on the Data Center, blogs, Facebook fan pages, and LinkedIn discussions. As well as user groups such as SHARE and IDUG.

The vendor directory section contains an up-to-date list of vendors, consultants, and service providers working in the z/OS environment. There’s a summary of the products they supply and contact information. There are a number of new organizations in the list this year, and a few have ceased trading.

The mainframe strategy section contains articles by industry gurus and vendors on topics such as: XML and SOAP data binding for enterprise applications; DataKinetics solutions for mergers and acquisitions; Thinking outside the box – monitoring DB2 security on z/OS; and CA Mainframe Chorus.

For many people the highlight each year is the mainframe user survey. This illustrates just what's been happening at users’ sites. It’s a good way for mainframers to compare what they are planning to do with what other sites have done. I will be looking at some of the survey highlights in my next blog.

The other good thing – as far as many of the 15,000 people who download it are concerned – is that it is completely FREE.

It can only be free because some organizations have been prepared to sponsor it or advertise in it. This year’s sponsors were CA Technologies, Canam Software, DataKinetics, and Type80 Security Software.

To see this year’s Arcati Mainframe Yearbook, click on www.arcati.com/newyearbook11. If you don’t want to download a large PDF, again this year, each section is available as a separate PDF file.
Don’t miss out on this excellent publication.

Virtual IMS user group

With so much of IBM’s software now in its 40s, it’s no wonder that using it requires quite a lot of knowledge. And many people have developed a whole range of nifty tips and tricks that they can use when things go wrong or to help make things work better. That’s where user groups come in. A user group provides an opportunity for people to share their hints and tips with others, and, in return, learn some tried-and-tested new ones.

One problem that managers sometimes have with staff going to user group meetings is that they are unavailable at work should there be a problem. In addition, there is often a cost associated with going to meetings – travel costs, meals, parking, subsistence, etc. That’s where the Virtual IMS user group scores. Not only do members get all the benefits of user group membership, but there’s no need for them to leave the office – they just join the meeting through their computer (hence the ‘virtual’ part of the name).

And the Virtual IMS user group is going to be busy in 2011. If you’re not already a member and you’d like to be, then go to www.fundi.com/virtualims and sign up. User group membership is FREE. This year there is an exciting programme of presentations at the virtual meetings – using GoToMeeting – starting on 8 February at 10:30 CDT with a presentation by Fundi Software’s Jim Martin entitled, “Solving the problem when IMS isn’t the cause”.

Jim describes the presentation like this: “Users might report slow response times from IMS, but you suspect that other systems are responsible. For example, what appears to be an IMS performance problem could be a CICS, DB2, WebSphere, or z/OS performance problem. Your challenge is to correlate performance data in IMS with activity in these other systems in order to discover the cause of the slow response time. In this session, we discuss how to approach this type of situation, how to gather the necessary information from multiple subsystems, and then analyse, diagnose, and resolve the problem.

On 12 April the user group meeting includes a presentation from Ron Haupert, a Senior Technologist with Rocket Software. His presentation is entitled: “Simplify and improving database administration by leveraging your storage system”. Ron is a database professional with over 30 years of related experience. He has developed relational database software, implemented large database systems, conducted database design reviews, and consulted with companies around the world on various aspects of relational database technology, database management tools, and integrated data management solutions.

On 14 June Ronnie Parker from Logic Online talks about: “The ripple effect of making changes”. The session describes storage-aware data management tools. These tools integrate storage-based fast-replication facilities with database management systems to provide fast and non-disruptive IMS and DB2 backup and cloning solutions. Storage-aware data management tools improve database backup, recovery, and cloning solutions by using storage-based fast-replication facilities to copy data; saving time and host CPU and I/O resources. The session explores how storage-based fast-replication facilities offered by IBM, EMC, and Hitachi storage systems can be used to backup, recover, clone, and refresh IMS and DB2 systems.

And there will be more great sessions in the second half of the year.

The user group is very grateful to Fundi Software for stepping in to sponsor the group (in much the same way that BMC sponsors the IMS Listserv at http://imslistserv.bmc.com/scripts/wa-BMC.exe?LOGON). Fundi Software is an Australian software product development company. Established in 1982, Fundi is today one of the leading providers of tools for IMS and CICS systems. Taken from the Zulu language, Fundi means “expert”.

The Virtual IMS user group is an independently-operated vendor-neutral group run by and for the IMS user community. The Web site contains an up-to-date list of IMS-related software that can be used with IMS; IMS news (information about new IMS products and new versions of existing products); a list of IMS consultant (let me know if your company needs to be added to the list); links to recent IMS articles that are available on the Internet; and links to IMS resources – in fact, it’s a one-stop shop for IMS professionals and other people interested in IBM’s Information Management System.

Mainframe computing 2011

This is the time of year when people make predictions for what we can expect to see in the coming year, so here are my predictions...

I predict that the Arcati Mainframe Yearbook will appear in early January and be downloaded by around 15 000 mainframe professionals. The Yearbook includes an annual mainframe 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.

I also predict the Virtual IMS user group will restart its virtual meetings and newsletters early in the New Year. Virtual IMS is a user group established as a way for individuals using IBM's IMS hierarchical database and transaction processing systems to exchange information, learn new techniques, and advance their skills with the product. The first virtual meeting takes place on Tuesday 8 February at 10:30 CDT. The presentation is by Fundi Software’s Jim Martin and is entitled, “Solving the problem when IMS isn't the cause”. Users might report slow response time from IMS, but you suspect that other systems are responsible. For example, what appears to be an IMS performance problem could be a CICS, DB2, WebSphere, or z/OS performance problem. Your challenge is to correlate performance data in IMS with activity in these other systems in order to discover the cause of the slow response time. This talk will explain how to do it.

With all the hype about cloud computing, 2011 is the year cloud computing will become commonplace. In many ways, this is a major technology change that is being driven by users. They like the simple life (or should I say, we like the simple life). It’s very easy to turn on your browser and have all the applications you want just there waiting for you – like the apps on your phone. You then use the applications as you want them. Users are looking for the same simplicity in their working environment and organizations are going to have to provide this paradigm-shift way of working.

And talking of smart phones, I predict that the device of choice is not going to be a small laptop or netbook, but a large smart phone (or small tablet). Something that you can fit in your pocket, but has everything you need to do a day’s work on it. And, of course, cloud computing makes this easier too.

I predict there will be more GUI-looking software on mainframes so that youngsters will feel right at home using the technology. And I predict there will be much more mainframe automation going on – which will allow the few experts available within an organization to do more work with fewer resources.

Social media will have embraced all sizes of businesses, so if you want to find out what IBM or any other major (or less major!) vendor is up to, you’ll be able to do it in the Twitter, Facebook, whatever, environment you are currently familiar with.

In the consumer market, I predict more people watching TV programmes through laptops and smart phones. It’s so easy and convenient to catch the latest news on a smart phone.

I predict that mainframes will NOT disappear in 2011.

I predict the arrival of more mainframe monitoring apps on smart phones – so you know straightaway if there is an issue with the network etc. You’ll then pull out your tablet or laptop and solve the problem using the nice GUI on the software.

I’d also like to predict world peace and harmony – maybe next year!
