2011 at iTech-Ed Ltd

Well, as another year comes partying to an end, and everyone stops checking their e-mails on their smartphones or tablets and finally starts to let their hair down and enjoy a glass of something alcoholic, I thought I’d review the year through the lens of my company – iTech-Ed Ltd (www.itech-ed.com).

January started the year, as most Januaries do, with the publication of the Arcati Mainframe Yearbook. The 2011 edition is still available for download from www.arcati.com/newyearbook11. The 2012 edition will be available in a couple of weeks. As always the Arcati Mainframe Yearbook  includes its 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. And each year, it gets downloaded by around 15,000 mainframe professionals.

February saw the launch of the new series of Virtual IMS user group meetings. The user group is now sponsored by Fundi Software and hosted at www.fundi.com/virtualims. The first speaker was Jim Martin from Fundi Software, whose presentation was called, “Solving the problem when IMS isn't the cause”.

In March, everyone seemed to be talking about cloud computing.

April’s meeting of the Virtual IMS user group included a presentation from Ron Haupert, a Senior Technologist with Rocket Software. His talk was called, “Simplify and improve database administration by leveraging your storage system”.

In May, Mark Lillycrop, Director of Arcati Ltd and I took part in a ‘Scheduled Chat’ in the ‘House of Mainframe’ section of CA’s May Mainframe Madness month. May also witnessed the launch of the new Virtual CICS user group – again sponsored by Fundi – with its Web site at www.fundi.com/virtualcics. Our opening presentation was from Fundi’s Jim Martin talking about, “Solving the problem when CICS isn't the cause”.

In June, I was asked by ITToolbox to lead a discussion in the Data Center Infrastructure section of their Web site. At the Virtual IMS user group meeting, Gary Weinhold a Systems Engineer and Verna Bartlett Head of Marketing with Data Kinetics talked about, “MSU reduction due to in-memory table management with (any) IMS applications”.

In July, I was selected for the Destination z (www.destinationz.org/) member spotlight. The Virtual CICS user group saw a presentation from Jeff Geminder, Principal Consultant with CA, called, “Cross-enterprise application performance monitoring and CICS-specific drill-down: approaches to finding the performance problem needle in the heterogeneous haystack”. I was also a guest blogger on the Destination z Web site.

In August, my article CICS Top Performance and Tuning Issues was published in z/Journal. I had a guest blog published on Destination z. The Virtual IMS user group had a presentation from Scott Quillicy, CEO and Founder of SQData. His talk was called, “IMS replication for high-availability”.

For the September meeting, Charles Jones, from the Product Management group at Rocket Software, gave a talk to the Virtual CICS user group called, “CICS TS 4.2: Leveraging event processing and high-performance Java”. I wrote a guest blog for the Destination z Web site.

October saw a presentation from Rosemary Galvan, Principal Software Consultant – IMS, with BMC. Her talk to the Virtual IMS user group was called, “Database Performance – Could Have, Should Have, Would Have”. I had a guest blog on the Destination z Web site.

In November, my Mainframe Update blog at mainframeupdate.blogspot.com was a finalist in the Computer Weekly Social Media Awards 2011. Also in November the Arcati Mainframe Yearbook user survey was launched. And Eugene S Hudders, president of C\TREK Corp, gave a presentation to the Virtual CICS user group called, “CICS TS Performance – Tuning LSR Pools”. I also had a guest blog on the Destination z Web site.

And finally, in December, I had an article entitled, Ways to Save Money and Improve IT Services published in z/Journal. The final speaker for the year at the Virtual IMS user group was Suzie Wendler, a Consulting IT Specialist in the IBM IMS Advanced Technical Skills organization, who talked about, “IMS V12”. I chaired a webinar for SQData entitled, “How Important is Continous Availability of Critical Applications to Your Company?”And there was a guest blog on the Destination z Web site.

What else, well apart from a full year of writing and consultancy work,  I was made an IBM Champion for the third year running.

Looking forward to 2012, we have the launch of the Arcati Mainframe Yearbook in January, and a presentation from Andrew Smithson of IBM Hursley on CICS Transaction Gateway V8.1 for the Virtual CICS user group.

If you do celebrate it, Merry Christmas and a happy New Year. I’ll be back blogging in January.

Mainframes, cloud, and trans-derivational searches

Communication is a bit of a hit-and-miss business at the best of times. Suppose I was sitting in a large comfortable leather armchair and I wrote the word ‘chair’. I would be thinking about my armchair. You might be sitting at your computer on an office chair with wheels and no arms. When you read the word ‘chair’, you might think that your office chair was what I had in mind. Perhaps a trivial example, but you get the idea.

What happens if I write a complicated sentence and it’s not immediately clear what I’m saying. You would read it and perform a trans-derivational search in your mind to try to find meaning. What is a trans-derivational search? Well, it’s a bit like going to Amazon and typing the word ‘cloud’ into the search box. Amazon will search in ‘Books’, ‘Film, Music & Games’, ‘Kindle’, ‘Electronics’, etc and display all the answers. You can then make a choice. When it happens in your mind, you do a similar search and select the search result that seems to be the best fit for the unclear sentence.

The reason I mention this is because when one person says the words ‘cloud’ and ‘mainframe’, the image in their mind may be quite different to the image in anyone else’s mind. I like to think of mainframes as interesting and powerful bits of kit that keep the business world turning. Someone else may picture rusting hardware that should have disappeared in the 1990s! It’s much the same with the word ‘cloud’. One person may envisage an outsourcing opportunity, while another may view cloud as a security nightmare – a disaster waiting to happen. You can see now just how tricky this communication stuff really is!

There are people who argue that the mainframe is a cloud already. Suggesting that both are resource that can be dynamically allocated and de-allocated on demand, and can be made available within a company with the necessary security and management controls.

Typically the users of cloud computing have x86 platforms and need to be able to get what they want when they want it – ie on demand. They use primarily Amazon, Google, or Microsoft services. And, of course, everyone is now talking about cloud with announcement of Apple’s iCloud.

Going back to the mainframe, recent surveys have shown mixed interest in cloud computing from mainframers. It seems that the closer to the coal face (or whatever the mainframe metaphor for systems people might be) people are, the less interested they are in cloud. Whereas more high-level thinkers are interested to see what advantages cloud computing offers their organization.

Same words, different mental picture. It’s that communication conundrum again.

If you do have any experience of using cloud and mainframes, I’d be interested to hear about your experience over on IT Toolbox (http://datacenter.ittoolbox.com/groups/strategy-planning/data-center-infrastructure-sp/featured-cloud-computing-in-a-mainframe-environment-4234328).

And for those of you who are IMS professionals, don’t forget the Virtual IMS user group meeting on Tuesday. Gary Weinhold and Verna Bartlett from Data Kinetics will be talking about MSU reduction due to in-memory table management with (any) IMS applications. Full details including how to register are on the Web site at www.fundi.com/meetings.htm.
