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!

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.

Merry Christmas and a happy New Year.

Should you refrain from using Chorus?

On 6 December, CA announced that CA Mainframe Chorus and CA Mainframe Chorus for DB2 Database Management were available. As it’s so close to the Christmas festivities, I thought I’d introduce this blog with a Christmas-cracker-style pun – well, it is that time of year!

Originally announced in May, CA Mainframe Chorus is designed to simplify mainframe management, and it does this, the CA press release tells us, through integration, automation, and modernization. Looking at this in more detail, the product helps:
  • Reduce the time and effort required to securely manage the mainframe environment.
  • Enable faster problem resolution and improved service levels.
  • Increase productivity for current expert mainframe staff and more rapid on-ramping of new staff.
“On-ramping”? That’s what we call a nominalization – a word referring to something you can’t put in a wheelbarrow! It sounds very dynamic, and each of us thinks we know what it means, but, of course, no-one actually does because you can’t see it or touch it etc. But let’s not pick holes in press releases or we could be here all day. And, as they say, let he who is without sin cast the first stone. And, as I said at the start, it’s coming up to Christmas.

Mainframe Chorus is designed to display information using a graphical user interface making the experience more familiar to younger mainframers’ previous experience of IT. This is all part of CA’s strategy to encourage younger people to work on mainframes and deal with the challenge of what’s been described as an ageing workforce. Of course, it’s not just youngsters who benefit from the new-look presentation of information, other mainframe experts can easily derive information from the screen displays.

The seven underlying products that support CA Mainframe Chorus for Database Management include CA Detector for DB2 for z/OS; CA Insight Performance Monitor for DB2 for z/OS, and CA Subsystem Analyzer for DB2 for z/OS. CA apparently plans to add additional roles such as security, storage, and workload automation in the future.

Mainframe Chorus for DB2 also allows users to optimize DB2 for z/OS performance by pro-actively monitoring thresholds and alerts that help to identify and resolve bottlenecks promptly. The data visualization capabilities allow administrators to display historical data to predict trends.

So, is Chorus a product you should refrain from using? Obviously not. It makes the mainframe easier to manage, it speeds up the identification and resolution of problems, and it extends the range of people who can use mainframe management software. If this is the sort of thing you need at your site, then it’s definitely worth a look.

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.

Cloud and the future of mainframes

CA Technologies released a survey on Wednesday entitled “Mainframe as a Mainstay”. The survey was conducted on 200 senior level US-based mainframe executives by Decipher Research. Amongst the results was the information that 73% of respondents confirmed that the mainframe is – or will be – part of their organization’s cloud computing strategy. The question posed at CA’s recent webinar was whether that result came as a surprise.

Now, as you may know, I’m a big fan of cloud computing. In fact, I’ve an article about cloud computing and IMS in the current issue of zJournal. It struck me that these results were very much in line with the recent results, also published by CA, from a survey carried out by Vanson Bourne, a market research company based in the UK. They conducted more than 300 interviews during August with European IT decision makers. Their report was called “Mainframe - The Ultimate Cloud Platform?”. They found a slightly higher figure of 79% of organisations believing the mainframe is an essential component of their cloud computing strategy. The also found 70% of respondents agreeing that cloud computing will sustain or extend the mainframe environment.

On the other hand, only 10 per cent of mainframe sites in BMC’s survey in October said that using their System z machines to run cloud computing or SaaS applications was an important priority for them in the coming year. Quite a difference! Similarly, my own straw poll at the Guide Share Europe conference at the beginning of November, in an IMS session, found that no-one seemed interested in cloud computing. I think that reflects real-life economics in that they were very much focused on what was available now that would make the business run better and their lives easier – how they could do more with less.

I think what we’re seeing is a difference between the attitude of mainframe staff, who want to get the job done with the tools available now and the pressure of fewer staff etc, and senior managers who are looking more strategically towards the next step.

The Arcati Mainframe Yearbook 2011 user survey has a couple of questions about cloud computing. It will be interesting to see the results from that. And, by-the-way, if you haven’t completed a survey yet, you can do so by going to www.arcati.com/usersurvey11.

Among the survey’s other findings we see:
  • A majority (80%) responded they will be maintaining or increasing spend on mainframe staff in the next 12-18 months.
  • More than three-quarters (76%) will maintain or increase their investment in mainframe software during the next 12-18 months.
  • Nearly half of respondents (46%) are looking for industry leadership from vendors on the evolving role of the mainframe in the enterprise.
  • 61% of respondents don’t believe the IT industry does enough to promote mainframe career opportunities to recent graduates.
  • 35% believe that recent graduates are not as proficient in mainframe technology as their counterparts that entered the workforce 10-years ago.
  • 61% said that hiring either took much longer than expected, took long enough to negatively impact their IT operation or are still looking for talent after more than six months.

Picking up on the 35% of respondents who believe recent graduates are not as technology proficient as their counterparts that entered the workforce 10-years ago, webinar panellists were asked whether this was something they were seeing in the workforce.

I think the truth is that even the ancient Greeks felt that youngsters weren’t as good as they used to be! Certainly when I started working on mainframes, we were a mixed bag of youngsters, and many of those less capable or that-way-inclined left – leaving the enthusiasts and the highly technically-capable. I assume the criticism can always be applied. New people at any job just aren’t very good. And once they are quite good, they’re promoted to a different one.

We hear the mainframe referred to as a dinosaur – even though we know signs point in the opposite direction – in addition, the mainframe has a reputation as older technology with a middle-aged workforce, so the panellists were asked whether the fact that 52% of those surveyed cited Facebook and LinkedIn as the most effective recruiting tools came as a surprise.

My first response whenever a sentence includes the words mainframe and dinosaur is to point out that dinosaurs ruled the Earth for 160 million years. Humans have existed for say 200,000 years. Draw your own conclusions!

I’m not at all surprised that middle-aged people are using Facebook and LinkedIn and many other examples of social media. At the end of 2008, the answer may have been surprising, at the end of 2009 it may have surprised some people, but not at the end of 2010. These are IT people we’re talking about – of course they’re going to know what’s going on in the cyber world. I also imagine, next year, that figure will be much higher than 52%. Mainframers know about social networking. Look how many of them blog and are on Twitter.

You can find more information about the survey at www.ca.com/us/news/Press-Releases/na/2010/CA-Technologies-Survey-Reveals-Mainframes-Role-as-Anchor-in-Cloud.aspx.
