I wrote about Second Life a couple of weeks ago and this might be a nice occasion to pick up the thread again - or to step in. This is the second 'Meet the Authors' event in a couple of weeks. What's it about ? IBM brings out a new Redbook, in this case still a draft : 'WebSphere Portal for z/OS Version 6'. Up to now the Redbooks were announced in the Redbook Newsletter, you could read a short description at the page of the book itself and decide whether or not to read the book. With this particular redbook IBM is presenting "IBM WebSphere Portal Enable for z/OS Version 6.0.0.1 , which is a combination of all the rich functionality provided by IBM WebSphere Portal for Multi Platforms and the Qualities of Service provided by the z/OS platform. The information in this book is based on experiences gained during an ITSO Proof of Concept in which we installed and configured WebSphere Portal on z/OS in a high available and secure environment".
What's new : you can now have a chat with the authors of the redbook in Second Life : "At this informal, online event in the Second Life virtual world, you can ask questions and discuss WebSphere Portal and Redbooks topics with subject matter experts while experiencing the unique atmosphere of the new virtual IBM Support Library in Second Life. You’ll also receive a free special edition T-shirt for your avatar and other freebies". Unfortunately you can't wear the T-shirt IRL (in real life). Still, I'm looking forward to attend one of these events, even if it's only out of shere curiosity. What's attractive is that the threshold to get into contact with the authors is lower than it would normally be. So I guess this might turn out te be a nice initiative.
The details : it takes place June 28, from 10:00 to 11:00 EDT (4PM-5PM in Belgium) in the IBM Support Library in Second Life. Check out all the details over here.

Five Year March to Simplification ?
Last october IBM announced its Five Year March to Simplification with an investment of $100 million "to enable technology administrators and computer programmers to more easily program, manage and administer a mainframe system (...)".
Yesterday there was a press release that you might very well call the first visible result of this initiative : 'IBM Simplifies the Mainframe With New Consolidation and Security Software'. The subtitle indicates that this is an initiative that's intended to go beyond the scope of current mainframe shops. IBM "Launches "IBM Destination z" to Speed Migration to the Mainframe".
The announcement is twofold. Firstly, there's the 'software simplification' part, mainly focusing on enterprise management and security. It's e.g. the Consul suite announced as the Tivoli zSecure V1.8.1 suite. There's 'IT Value Based Analytics (ITVBA)' which is some kind of charge-back management ("relating IT costs to business services") software. And there's once again the positioning of z/VM as THE virtualization platform. I must admit, at first sight I'm not immediately seeing the benefit of these in terms of simplification towards "managing and administering a mainframe system".
Secondly, there's IBM Destination z. IBM calls it "an online meeting place (available at www.ibm.com/systems/destinationz) for customers, systems integrators, IBM Business Partners, software vendors and academic institutions to connect with each other and with mainframe experts, access development tools and the latest mainframe solutions. IBM Destination z provides links to platform economics -- such as total cost of ownership tools -- and case histories that reveal financial and business benefits (...)".
Again the focus is much more on 'simplifying' your 'IT environment' in terms of consolidating distributed systems to the mainframe platform and offering information to the SMB companies about the assets of using the mainframe platform. It's a valuable initiative, that's for sure. But I personally expected the simplification initiative to cover other grounds. I expected to see some real simplification in terms of mainframe system administration like e.g. the promised new versions of 'msys for setup' and 'msys for operations' - as was announced at first. You can read some quotes of that first announcement over here. I have the impression IBM is starting off with the second step of the process, which would've been lots easier and more attractive if they had first implemented their initial promises. Correct me if I'm wrong !

Webcasts and Teleconferences
I would like to draw your attention to some Webcasts and Teleconferences - especially because there are a couple of them about IMS and IMS is not that often in the spotlights. IBM actually has a page listing upcoming webcasts and upcoming teleconferences. About the timing, most mention EDT, which has a six hour time difference with Belgium and its neighbouring countries. Most of the time they are organized in the morning so that it's late afternoon over here. Here they are :
So it might be interesting to check out previous webcasts and teleconferences.
- June 19, 2007 11.00AM EDT : 'An IMS overview: The Business value of IMS and SOA'. "This presentation will give you an overview of IMS and how IMS enables you to reuse your existing investment and enhance the SOA journey".
- June 26, 2007 9.30AM EDT : 'The IMS Tools Knowledge Base: The foundation of IBM's autonomic direction for IMS Tools'. The teleconference discusses how the IMS Tool Knowledge Base "improves problem determination and resolution, consolidates islands of IMS tools data into one repository and builds a foundation for better decision-making".
- June 27, 2007 11.00AM EDT : 'Accelerate and simplify adoption and deployment of SOA with Rational Business Developer extension'. "This teleconference will show how the use of Enterprise Generation Language (EGL), the language within Rational Business Developer extension (RBDe), can help significantly reduce costs and deliver innovative SOA solutions to the business faster. It lets you quickly and simply develop business applications and services, while shielding developers from the technical complexities of different platforms and middleware".
So it might be interesting to check out previous webcasts and teleconferences.

Redbook : DB2 9 for z/OS Technical Overview
I don't know if all readers of this blog are familiar with the work of Frank Zappa. No, he's not a system engineer or a mainframe guru, but a musician. Every time I start a topic on DB2, one particular song of his comes to my mind : "You are what you is". That's exactly the reason why I'm paying more attention to DB2 than e.g. to Websphere. I've been into DB2 programming and DB2 adminstration for almost 20 years now. So, allthough most of my time goes to System z presales, I'm still 'dba-ing' from time to time and following the scene closely.
So here's 'DB2 9 for z/OS Technical Overview' a redbook (draft) giving you an overview of the new DB2 version for z/OS. "Its scope is to help DB2 for z/OS users understand the functions offered by DB2 9, justify their investment in installing or migrating, and start planning for prerequisites in exploiting the key new capabilities". As I was writing this post, I saw Willie Favero had already covered it too in his blog, and according to him it's not a draft anymore, as it's nowhere mentioned in the book itself.
Well it's nearly 600 pages but it looks quite thorough. I've just browsed through the XML section and it gives lots of useful information and examples going through every detail. I think, this will become a valuable work of reference.

Redbook : Implementing Rexx Support in SDSF
Dolmen is hosting the three-monthly meeting of the Belgian GSE (Guide Share Europe) zOS working group. The latest was last week and we also had a 'z/OS 1.9 Preview' presentation. If you're interested you can find it (amongst some other presentations) on the download page of the Belgian GSE z/OS Working group site. One of the things that was mentioned was the new System REXX. You can now run REXX outside of TSO via programming interface or operator command. One of the uses of System REXX is that the Health Checker now support checks written in System REXX.
The redbook 'Implementing REXX support in SDSF' (still a draft) how REXX support has been added to SDSF in z/OS 1.9. "This function provides the ability to access SDSF panel data through REXX variables. In addition, the data can be modified in a manner similar to SDSF action characters and overtypes. SYSOUT data sets can be browsed using EXECIO or printed using SDSF functions. This book describes the new support and provides sample REXX execs that exploit the new function." The Redbook provides lots of samples so that you can immediately (well, not before september) try out lots of "real-world tasks related to operations, systems programming, system administration, and automation".

Software withdrawal IBM System z Products
Yesterday IBM announced a list of products that will be withdrawn from marketing (WDFM).
Regarding the operating systems z/VSE 3.1 will be WDFM on May 31, 2008. But perhaps more important : z/OS.e 1.8 - as you know this is the last version of z/OS.e - will be WDFM October 22, 2007. If I'm not mistaken, that's about a month later than z/OS 1.8 itself. So what's the planning for z/OS.e ?

IBM and Second Life
A couple of weeks ago IBM published a press announcement about opening a Business Center in Second Life, where you would be able to go through the whole purchasing process up to the point where the contracts are signed. Are mainframers supposed to know what Second Life is ? Well, I’ve got two adolescent sons walking around the house and it’d been in the news a couple of times. So, until now, I was at least aware of its existence.
In short Second Life is a completely virtual world, which, as I came to find out, is really huge. People are leading – as the name suggests – a ‘second’ completely virtual ‘life’. And leading such a virtual life seems to be very attractive as about 6 million people are signed up in Second Life and there are usually some 30.000 people online. So, why not put up a virtual Branch Office of IBM.
But why did IBM put up a Business Center in a world I mainly associated with free time and gaming ? My mistake, I found out that lots of companies are having locations in Second Life and that IBM really has a vast representation over there. Name a lab, it’s there : Hursley, Boeblingen . . . Name a country : IBM Italy, IBM Benelux . . . it’s all there. So, IBM must have a solid belief that Second Life is really adding value to their business. And more than 200 IBMers are active in Second Life.
Of course I had to go and see for myself and perhaps meet with the IBM staff of this Center in person. So I made an account (MarcW Writer – you have to pick your lastname from a list) and I set off for my first virtual journey. Actually that wasn’t so difficult. The announcement gives the SLURL (Second Life URL) for this Business Center. You’re immediately teleported (hey, it’s a virtual world) to the entrance of the Business Center. I had some trouble finding my way at first, but after a while I arrived at the heart of the center. Indeed, some IBM people were present. I had a little chat with Takeshi Sautereau, who showed me around a bit and whose task it is to help clients, answer their questions, give them the necessary information . . . So say hello from me to Takeshi when you get over there. He complimented me on my blog, by the way. So even in virtual life, my reputation was already running ahead of me ;).
I went back a couple of times wandering through the Redbook library, a virtual museum, the meeting rooms and even some large conference rooms, but you cannot say it was very crowded at those places. I didn’t meet any Benelux people in the Benelux area. So, though I can see the potential of it all, I’m still puzzled at where this will lead to. I also talked to Maximiliano Ducatillon (IBM) and he pictured the center as an alternative means to meet customers. He will invite me to the next conferences because I really would like to see some more people over there. I’ll keep you informed.
What can I say, I’ll have another go at it, but for the moment I’m mostly confused and wondering whether ‘real’ clients with ‘real’ IBM contacts, will really find it a benefit to go and do business or even find information in this ‘virtual world’ ? But then again, it also took quite some time for the internet to get incorporated into business life.
I’m sure I will get back to this subject, when I’m virtually grown up – no pun intended ;), I think.
So, if you didn't get the message :
just register and go and take a look for yourself !
Any comments about experiences are welcome !

Mainframe emulation : a sequel
'Gaming and mainframing on a PS3' might've been a bit of a provocative title, but this mainframe emulation problem is something that really concerns all mainframe developers ànd users. Even if you, as a user, have no intention to use a FLEX-ES system, the problem might still come back and haunt you.
Just as I had published my post last Wednesday, I received Cheryll Watson's free 'Cheryll's List'. If you don't receive it, you can subscribe to it over here. Cheryll gives a comprehensive insight view to the matter. When IBM doesn't offer a solution soon, then I'm afraid that one of her conclusions will be more than correct : "So you might ask, "What does this have to do with me?" If IBM continues on this path, small software vendors will either have to raise their prices considerably or will leave the software business. That will provide less competition and fewer choices for all z/OS users. These negative consequences will be bad for the entire platform, no matter how large or small your operation".

Gaming and Mainframing on a Playstation 3 ?
I guess it was a little stream of consciousness that made me cough up this title.
What's it about ? I was just reading the main article of zJournal : 'The State of IBM Mainframe Emulation' by Philip Smith III. You should really read it to get a comprehensive view on this matter. There has been much ado (I must be in a literary mood) about mainframe emulation lately. Also Pete Clarke is voicing his concern on this issue in his comment on z/VSE in the same zJournal issue.
What's the problem : IBM has not prolongued its agreement with Fundamental Software that delivers FLEX-ES, the main (Linux based) software platform for mainframe emulation. What are the consequences ? Since IBM did not continue the agreement, no FLEX-ES systems can be sold since November 2006. "Simultaneously, IBM stopped licensing software on FLEX-based systems, so existing Fundamental customers can’t add IBM products to their systems. While commercial FLEX-ES customer machines will continue to run indefinitely, many small mainframe development shops have embraced FLEX solutions through IBM’s PartnerWorld for Developers (PWD) program—and these machines are controlled by a time-limited hardware dongle. When the dongle expires, FLEX-ES will no longer operate. For these sites, the clock is running, and finding an alternative is critical !"
Are there any alternatives ? Not really, the only 'safe' solution for the moment is buying a z9 BC, but that's actually quite expensive as you also have to buy external storage. Not really a choice for small developers. The not so safe and perhaps not so legal alternatives either are PSI and Hercules. Firstly IBM filed suit against PSI and the end of this doesn't seem to be in sight. You can find more information on this in Phil Payne's report on the case. Secondly, Hercules is a well known mainframe emulator (mainly on Linux) but IBM has never wanted to licence its operating systems on Hercules.
Another alternative, just a rumor for the moment, is that IBM might offer a low-end machine "perhaps using the IBM’s new Cell Broadband Engine (CBE) processor (...) It’s easy to imagine (if not easily implement) an emulator running under Linux or AIX on CBE-based hardware". What's the CBE processor ? It's IBM's 'game' processor that is used in Sony's Playstation 3 and that's also announced to be used in the mainframe (the 'IBM Gameframe'). And what do you know : you cannot only play games on a PS3, it can also run a complete Linux machine.
Hence the little twist of the mind that produced the title of this topic.

Sampling Techdocs
I hadn't found the time recently to see if there was anything worthwile in Techdocs. So I finally got to browse through last month's content and came up with some interesting documents. I'll just sum them up, so you can pick up what you like.
It might not be such a bad idea to keep doing this on a monthly basis.
It might not be such a bad idea to keep doing this on a monthly basis.
- Presentation : 'SNA Basics for the new SNA System Programmer on z/OS'. This one's a very nice, no nonsense, introduction to SNA : "The expected audience is people new to SNA or those who are coming back to SNA after an absence and need a refresher on some of the basic elements".
- White Paper : '3745 Migration Paths: IBM Communication Controller for Linux on System z9 and zSeries (CCL) or Enterprise Extender (EE)?'. Though IBM has no plans to end support for the 3745 before 2010, it might not be such a bad idea to have a look at its successors and the differences between the two solutions.
- Presentation : 'Overview of Communication Controller for Linux (CCL)'. This one rounds up the first three documents about SNA, 3745 and how to replace them.
- Presentation : 'DB2 for z/OS – What’s tape got to do with it?'. I find this an intriguing title and so is the contents of this document : "Should I be sending my DB2 archive logs and/or image copies to tape? Do you have or have heard of tape virtualization, maybe VTS, or own a new spiffy IBM TS7700? How large are tapes these days and how can I control my allocations? What happens if I lose a tape or the tape controller? Have you heard that tape is really disk, but tape also? What does this all mean? By the way, how does DB2 deal with the new tape technology and what are best practices when dealing with this new tape technology?"
- White paper : 'Capacity Planning for zIIP-Assisted IPSec'. The z9 EC GA3 and z9 BC GA2 announcement previewed moving IPSec processing from general-purpose processors to the zIIP. This document elaborates on this preview with a functional description, software requirements, capacity planning and some performance results from the IBM research labs.
- FAQ : 'Which TS7700 Virtualization Engine functions became available in which Code Releases and which LM code is co-reqed?'. Not much more than a list, but you never know it might come in handy !

Announcements : ESS and DS8100
Yesterday, most, if not all, features of the Shark (ESS800) and the Baby Shark (ESS750) were announced to be withdrawn from marketing as from November 30, 2007 onwards : expansion racks, disk eight-packs, host adapters, cache ... So anyone still planning an upgrade on their Sharks ...
On the other hand the DS800 now has third and fourth expansion unit support providing "up to 307.2 TB of physical capacity with 300 GB Fibre Channel disk drives, and up to 512 TB of physical capacity with 500 GB Fibre ATA (FATA) disk drives". Another addition is Single Phase Power Support. Since IBM introduced the choice of the guarantee period, there's every time two announcements : one for the original 2107 Machine Type and one for the 2121-2124 machine Type series.

Hot Flashes and Tool Bags
I'm referring to two presentations I stumble across from time to time and when it happens I always take the opportunity to have a look. Both are regularly updated and each time contain some goodies and pieces of information that make them worth checking out.
The first one is "Cheryl's Hot Flashes". You can find it in the presentation section of Cheryl Watsons site. She is regularly presenting it at user meetings like e.g. the Share meeting at Tampa in February. There's e.g. always some interesting survey results : who's on z/OS 1.8, how many people are using the zAAP/zIIP or are planning to. But the last one also discusses user experiences on zIIP and there are always some quite technical topics too like e.g. 'interesting APARs' ...
By the way, all Tampa Share presentations are available on the Share site.
The second is "A System Programmer Productivity Tool Bag" by Bette Brody. you find the latest two versions over here with a list of topics covered. This one really contains a wealth of information for every system programmer focusing on recent announcements, Statements of Direction, interesting new publications, redbooks and white papers, downloads like e.g. the Health Checker and the free Omegamon z/OS management Console, some info on using ShopzSeries, tips on installing Server Pacs, the use of all kinds of tools like zPCR, some interesting z/OS links and many other topics.

She is regularly presenting it at user meetings like e.g. the Share meeting at Tampa in February. There's e.g. always some interesting survey results : who's on z/OS 1.8, how many people are using the zAAP/zIIP or are planning to. But the last one also discusses user experiences on zIIP and there are always some quite technical topics too like e.g. 'interesting APARs' ...
By the way, all Tampa Share presentations are available on the Share site.
The second is "A System Programmer Productivity Tool Bag" by Bette Brody. you find the latest two versions over here with a list of topics covered.

ISPF or Xedit : ISPF !?
The first editor I got to work with on the mainframe (or on any platform for that matter) was ISPF. After half a year I switched from MVS to VM and from ISPF to Xedit. I was - to say the least - overwhelmed by the many commands and settings in Xedit. Afterwards, when I got to work with ISPF again, I realized that lots of it can also be done in ISPF. And if it can't, you can always try and write a macro for it. If I had to make a choice . . . let's skip that one for the time being. To be honest, the ideal editor would be a mixture of both. In each editor, there are some features that are missing or that are for better covered in the other.
In this topic I'd like to focus on the ISPF aspects which are not that good or not at all covered in Xedit. I must say, however, this is entirely my personal opinion as this seems to be a sensitive topic : there have been more than one discussion on this topic in the IBM-Main discussion list
First of all I find the 'find-replace' commands to be far more intuitive in ISPF. Locating a target in Xedit only gives one occurence per line. That's not what I want : I just want to find every occurence in my file. So I have to use clocate. And you always have to be very aware of your position in the file in Xedit, more than in ISPF. Furthermore there's no RFIND. You have to re-issue the command. Some other things missing : FIND FIRST, FIND LAST, FIND PREV, FIND NEXT, FIND PREFIX, SUFFIX, WORD and FIND ALL. The last one can more or less be replaced by COUNT. No FIND P' ' (picture string) either. I use that a lot in ISPF.
The same goes for changing data : only one occurence per line, unless you indicate otherwise. And I find it so annoying, that afterwards, you're positioned at the bottom of the file as first line on your screen. There's no RCHANGE either.
What I'm really missing in Xedit is the UNDO command. It's just not there. The only thing you can do is recover deleted lines. If anyone has a solution for this, comments are welcome !
Line commands 'UC' and 'LC' do not exist in Xedit. There's only UPPER and LOWER issued from the command line. But then you really have to pay attention if you only want to transform a couple of lines. Just as with PUT-GET, the equivalent of CUT-PASTE you have to indicate the number of lines from the command line instead of indicating the range in the prefix area. Another line command that's replaced in that way by a primary command is the copy-overlay function (COVERLAY command in Xedit).
The tabbing is more elaborate in ISPF. There's only an equivalent of software tabbing in Xedit.
And it's sometimes very little things which you happen to use that you're missing : the FLIP command e.g. OK, you can also write a macro for it of course. As I also did for scrolling up or down the screen so that the cursor position becomes the first or last line of the screen (Scroll Amount=Cursor). PF7 and PF8 always scroll entire pages in Xedit.
Don't worry if I make Xedit look like a poor editor. It surely is NOT.
I'll come back on this topic with a sequel : 'Xedit or ISPF : Xedit !?'.

Project Big Green
Yesterday, I mentioned that IBM definitely had more up its sleeve concerning 'energy efficiency' in the data center.
So here's the press release from IBM now officially announcing their 'Project Big Green' : 'IBM Unveils Plan to Combat Data Center Energy Crisis; Allocates $1 Billion to Advance "Green" Technology and Services"; This has of course a larger scope than just the mainframe. The summary :
