New initiative : Mainframe Linux Wiki


I think this is an initiative worth mentioning and I hope it'll be a successfull one. It was cross-posted by Mark Post on the Linux-390, IBMVM, and IBM-Main Discussion lists : "With the assistance of Marist College (and Velocity Software who owns the domain name), I've put up a Wiki at http://wiki.linuxvm.org/wiki/ for people to contribute content". This should become a wiki for mainframe Linux an z/VM and it's now up to people like you and me who want to share their knowledge and experience with the rest of us.

Suggested topics so far include :
For the moment only the 'Technical Presentations' has content with already a nice collection of presentations from previous Share, WAVV, System z Expo ... meetings.

As I said, I hope this becomes a success story !

Wikipedia

A couple of weeks ago, my son had to make a presentation for school on a French city of his choice. He chose Le Havre as we've been there before and it's not as obvious as Paris. I helped him a bit finding the right information and Wikipedia turned out to be his best source of information. I wasn't really all that suprised because I find myself more and more often consulting Wikipedia, also on mainframe topics. I used to be a little sceptic about it as anyone can contribute to Wikipedia and you're never sure whether it's trustworthy. Still, Wikipedia has proven to be a good starting point when you're looking for decent information. Some examples ?

There's an entry on CICS. And we can immediately indicate why the information is usually quite to the point. I use this CICS page as example : there are always three additional tabs : if you want to check whether the information is up to date, you can check the history page. If you do not agree with some of the statements or if you think some of them need clarification, you can turn to the discussion page. And if you are a real expert on the subject, you can always edit the article yourself. And I think this auto-correcting character of Wikipedia (in most cases) just works fine.

You can also find spin-offs of some subjects with a wiki entirely dedicated to one subject. Again I can take CICS as an example. as there's a separate CICS Wiki. This "wiki is dedicated to act as a living knowledge base for CICS and CICS related products".

And of course there's also a System z9 page. But there's more. Here you can see that Wikipedia is really kept up to date. There's already a topic on a Future Machine. A couple of months ago there was quite a lot of talk about a new mainframe processor, called z6, that was announced by IBM. Well, this article already has a link to the presentation of this 4+Ghz processor. No, this is not a christmas gift by IBM. As the article states "As of November, 2007, IBM had not yet shipped a machine using this new design". And, for the time being, this hasn't changed yet.

Is COBOL killing CICS ?

How's that for a starter ? I must immediately admit, it's not my quote, it comes from Corneel's Blog at the CICS Community Forums page. I recently came across this blog of Corneel Booysen, also the driving force behind the CICS Wiki, I discussed earlier. He writes a great article on how COBOL is a threat for CICS as CICS is put in the same bad daylight as COBOL. I hope Corneel won't mind me quoting a couple of extracts. But be sure to read the entire article. And there'll be coming an 'Uncertain Future of CICS Part 2'.
The very same thing that has been the bread-and-butter of the mainframe for so long and has helped IBM build their mainframe empire – is the thing that threatens to kill it but more specifically in this case – CICS. The monstrous monolithic mass that is the 500 billion lines of COBOL code that companies still maintain has become a dingy little secret that is kept in the basement of many a fortune 500 company. That missing code, the retiring programmer community has become the “Unmovable Object”.

Companies actively develop themselves out of trouble. They have given up on converting or migrating COBOL code or COBOL people to anything else. They replace the functionality with newer systems, in modern programming languages developed by enthusiastic people that enjoy working with computers. In fact I dare to say that the users of modern programming languages and technologies has a much firmer grasp on information management and computer science theory than the typical COBOL programmer.

A couple of posts earlier Corneel is also discussing 'The Aging Mainframe Workforce' : "I believe that IBM is dedicated to the future of the mainframe. The question is - are we? I suppose (or hope) the initial response to the question would be “Yes”. But the unavoidable follow-up to that is - what are we doing about it? Are we creating an environment that promotes and nurtures new talent?" For the answer, you'll have to read his post.

Corneel also points to another CICS blog that has just started : 'The Master Terminal'. Its intentions : "This unofficial blog is written by a hopefully expanding group of people in IBM Hursley and beyond who work on CICS. Expect to see posts on conferences, code samples, helpful hints and anything else that we can think of". It does look interesting but I'll hold my 'judgement' as they only started out March 31, 2008.

But I think I found two interesting blogs on CICS worth checking out regularly.

Looking back on 2009 - Year Review

Cloud, Dynamic Infrastructure, economical crisis, Smarter Planet, energy savings, zPrime, Solution Editions, SaaS (Software as a Service). Ok, I admit, I'm just trying to get as many hits from Google putting all the (excuse me) buzzwords of the year 2009 together. Perhaps I should add Twitter as well, no ? Just kidding, nevertheless, I think these terms pretty well sum up any IBM Mainframe Review for 2009. Let's get into some more detail looking month by month what happened on the mainframe front.

January. After IBM took over PSI in July 2008 and withdrew the FLEX-ES license for ISVs, no wonder voices were raised that IBM now really had a mainframe monopoly. T3 files an antitrust complaint against IBM, which will later in fall be dismissed by a federal judge. But at the same time however, the Department of Justice will start an investigation whether IBM really holds a mainframe monopoly.

In February IBM introduces Dynamic Infrastructure as the successor to New Enterprise Data Center as this was a bit too focused on (mainly) a green Data Center only. And throughout 2009 Dynamic Infrastructure turns out to be the underlying vision for most announcements with its three cornerstones : Improve Service, Reduce Cost and Manage Risk.
In February we also see a first of a series of announcements for the DS8000 with full disk encryption, Solid State drives, Remote Pair FlashCopy ...
We also proved that mainframe definitely isn't dead, not even for traditional workload as we won the 'STG Winback of 2008' for a customer who migrated its IDMS applications from a Siemens platform to the z10.

IBM announced GDPS V3.6 in March with improved coordinated disaster recovery across heterogeneous platforms, increased availability and simplified management.
We also hear the first buzz about Windows on mainframe from a company called Mantissa with its z/VOS application. This should run as a sort of emulation on top of z/VM, but hasn't been brought to market as far as I know.
Softek LDMF or zDMF as it's called now goes to V3.2 eliminating some of the disruptive actions like e.g. for DB2 datasets.

In April, CA introduces its "Mainframe 2.0 strategy and how it will transform mainframe management at your organization". This will be followed by CA's May Mainframe Madness (which, by the way, will recur this year) and CA's Mainframe Software Manager product, simplifying software installation and management for both experienced and new mainframe system engineers.
We also see the next round of Dynamic Infrastructure announcements on April 28, 2009. Talking about the three cornerstones to mainframe customers, we all came pretty much to the same conclusion as IBM : "System z’s core competencies align with a Dynamic Infrastructure Today". IBM also explained what this meant for the future of System z : we will not only see it as a central data repository but also as the central management platform for the entire IT-environment. It talks about Application Serving Blades and Accelerators, which can both be seen as non-z extensions of the well-known specialty engines. One example is the Smart Analytics Optimizer which is expected to be announced in 2010.
What were the actual announcements also made on April 28, 2009 : z/VSE 4.2, TSPC (Tivoli Storage Proeductivity Center) 4.1, CICS Transaction Server for z/OS 4.1 and some enhancements for z10 EC and z10 BC.

May was a bit calmer so I took the opportunity to have a look at some of the 'new' networking tools like LinkedIn, Facebook and Twitter. Let's say I'm no Facebook fan, but although I had my doubts about Twitter, I'm still tweeting though I mainly do so to automatically announce my new blog posts. Still, I've found it useful to pick up some first hand information on events and new announcements from the people I follow.

I know, CA's May Mainframe Madness was the month before but the tour only hit Belgium in June. It also was a good occasion to bring a CA survey back under the attention stating "that while on average 50% of all corporate critical data are on the mainframe, the cost on average is only 19% of the total IT-budget". CA also announces support for the zIIP for Datacom. Talking about specialty engines, June brings us the first mention of zPrime, some month before it's actually announced.

In July Neon Software introduces zPrime. zPrime enables mainframe customers to offload more traditional workload to the specialty engines than IBM finds eligible. Let's say it has been a bit of the talk of the town since eventually leading up to Neon suing IBM. We'll surely see some next episodes of this story in 2010.
We also get a preview of z/VM 6.1. It's particularly the statements of direction that are of interest : z/VM Single System Image and z/VM Live Guest Relocation. We're definitely looking forward to this.
More storage announcements as well with the next generation of XIV, R4.3 of DS8000 and V2.3 of the Data Deduplication TS7650 ProtecTIER Gateway & Appliance. And the announcement of FICON Express8 for System z10.

August brings us the announcement of Enterprise Cobol for z/OS 4.2, z/OS 1.11 and perhaps even more interesting z/OSMF (z/OS Management Facility). IBM seems to be finally delivering on its promises about its 'Five Year March to Mainframe Simplification' it made a couple of years ago. Talking about this to our customers also brought some sarcastic smiles to their faces : "Yeah, right, another Msys for Setup. What, even better ?" All in all, I think this is a fresh start and z/OSMF definitely deserves a chance.

In September we organize a joint IBM - Red Hat - RealDolmen meeting for customers who are interested in consolidating to Linux on System z. Linux on System z is definitely drawing more and more attention. I also see this when I'm attending an 'Introduction to zLinux & z/VM' Proof of Technology a couple of weeks later. So we're not suprised to also see a new Wiki on mainframe Linux and z/VM come to live.

We have lots of announcements in October starting with IMS Version 11. Next we have z10 EC GA3 and z10 BC GA2, the new DS8700 announcement, new functions of the TS7700 and TS3500, the actual z/VM 6.1 announcement and a preview of z/VSE 4.3. Sometimes to my confusion, it's all linked to Dynamic Infrastructure.

After that November and December are rather quiet months. One particular incident shows me to be careful with Twitter and with people who are (to my opinion sometimes) using it incorrectly. I wrote about a presentation on zPrime in November saying "Apparantly customers are going into production with it and they actually seem to pay less". This turned up on the zPrime Twitter account as "Mainframe Watch Belgium: Customers are in production with NEON zPrime and they really are paying less". Not my words.

Now you will say, what about cloud ? Well, I've looked it up and so far I only used the word sideways in two of my posts. The first time I heard about it, I just thought that we've been doing this already for centuries. But now it seems to have a name, or should I say, a new name. As you see, I'm still in doubt whether this is more than just another buzzword which will be replaced by another one next year.

Looking forward to 2010, it's possible that I will also broaden my horizon a bit, as I obtained my technical certification on XIV a couple of weeks ago. But then again, didn't Moshe Yanai mention at a customer event in November that connecting XIV to the mainframe was on the roadmap of XIV. I guess only the future can tell and we'll see more of this and other subjects I just mentioned in 2010 !
