We don't know what the next year will bring us but I surely wish every one the best for 2012 : A Happy New Year and good health to you and your family.
Thanks to all my readers for stopping by so regularly, to all the people who linked to this blog and to every one who gave me great feedback during 2010.

So here's a nice, short history of Linux.
Want to see some more : check out the Mac vs PC vs Linux ads on youtube.

So, here we have again 5 predictions that might become reality within 5 years. Are they realistic ? Frankly, I don't think so. Can I prove it ? No, but . . . first take a look at this year's issue.
And now we move on to the first one I've found which dates from about 5 years ago. We can check which one of those have become true. And you'll see : mind reading should no longer be a prediction in 2011, it should already be reality.
If, just for fun, I should have to choose one prediction to become true I would pick the next one. And though it's presented with a woman, I think men would even love this more. I know I would. So for all the men who hate shopping or who think shopping with their wives takes too long. Here's the solution. Well, almost !

In February I found out how important social networking can be ànd how willing people still are to help each other. I got news from IBM Techline that you always have to have SSD in your DS8000 to use Easy Tier, even the manual mode. In just a couple of days Nick Clayton (IBM) and Antony Vandewerdt (IBM, Aussie Storage Blog) contradicted this. Thanks, guys. You could actually hear my sigh of relief that I hadn't been telling any lies to my customers. IBM also changed its statement of direction on ESCON telling us that after the z196 (and implicitely the, yet to be announced, z114) ESCON would be a thing of the past. No carry forward either. Period.
I still remember that in March I was really excited about the preview of z/OS 1.13. This had to do with changes to the Batch Runtime environment and lots of improvements/additions to z/OSMF with software deployment, Storage DASD management and Capacity Provisioning. And if I saw a positive thing about social media and such in February, the zPrime Saga gave us a downside of all this. Alan Radding aka DancingDinosaur wrote a very enthousiastic piece on zPrime mentioning really amazing savings for one company. But the same day the post had already dsiappeared. So beware, you can almost never delete all traces of anything you wrote. I had the post in my feed reader and you can't come and delete a feed on every computer that's out there.
In April I wrote an extensive piece on the DataPower appliance on zBX (XI50z). I still think these 'accelerators' are an added value to the hybrid zEnterprise and you can be sure there's more to come of these. The mantra of this year (whether you like it or not) : some more price 'changes', this time on the zSecure products and all FWLC products. Further, there's the announcement of CICS TS V4.2 and a clear statement of direction by IBM to deliver Linux on zBX in Q3 and Windows on zBX in Q4, which they did. There was also a preview of z/VSE V5.1 and we saw the first DB2night shows for z/OS.
May gave us the first wave of storage announcements of 2011 with innovations on nearly every mainframe related storage component. The DS8000, which by now definitely only means DS8700 and DS8800 gets Easy Tier V2, the priority manager ... We also had the new TS1140 tape drive.
In June we finally see 'The End' for zPrime and we can now put the link to our February story. zPrime has also become a thing of the past. And of course there was some great news for our own company. From now on, with the support of IBM, we're teaming together with Sogeti for mainframe opportunities where we both can mean an added value for each other.
Why IBM chooses July to announce a new zEnterprise system is totally unclear to me. Every one (at least in Europe) is on vacation in that period. Still, great announcement of the z114 which gives the Business Class customers also the opportunity to have a real zEnterprise System. I'm not going into too much detail (you can read everything over here) but, when we take a look at the really new stuff, it introduces the new PCIe I/O drawer and the Intel Blades for the zBX. There is no technology dividend for the z114 but there's a new and better pricing : AEWLC. But, better is a relative word because, here we go again, it sets off against a price raise of 5% for all EWLC customers starting January 2012. Next to that there's also the announcement of the new 3592 Model C07 tape controller which now includes library management functions. This makes the 3953-L05 Library Manager unnecessary for any mainframe customer.
After all these announcements August and September were really calm months. We saw the obvious thing happen : the 3953-L05 Library Manager was actually withdrawn from marketing. Just like last year, the Total Solution event for System z organized at the IBM forum was a success and there are already plans in place for a new edition in 2012.
October was also quite eventful this year. There were the software announcements of Enterprise PL/I for z/OS V4.2 and of (who said this was old and obsolete ?) IMS 12 Transaction and Database server. On with the storage announcements with XIV Gen3 with support of 3TB SAS drives and a mobile monitoring dashboard for iPad. We also see StorWize expanded to the StorWize Unified System supporting NFS/CIFS/FTP/HTTPS/SCP file protocols in addition to existing block protocols (iSCSI and FCP). DS8000 gets some new features supporting an additional frame on the DS8800, supporting three drive tiers for Easy Tier and I/O Priority support for System z volumes. And don't forget the new mainframe announcements with Windows on zBX, IDAA (IBM's DB2 Analytics Accelerator) and, last but not least, the Tivoli Storage Manager for z/OS Media making it possible to keep using z/OS FICON attached storage when migrating TSM to another environment.
As last year, November and December were rather quiet months. So I took the opportunity to write a bit more detailed on the Tivoli Storage Manager for z/OS Media and IBM's DB2 Analytics Accelerator (IDAA).
Software pricing is always a delicate story but it surely represents the larger amount of the mainframe cost. And I can tell you that most customers weren't really happy with all the price 'changes' that came their way in 2011. Especially the 5% price raise on the EWLC pricing was not very kindly received. Even if it's justifiable, you know how it goes : it's the perception that counts.
Here's a great role for hybrid computing. Now that zBX is also available on the Business Class Systems, I think that 2012 will be a crucial year for the breakthrough of it. We have more than a year of experience with it on the z196 and with that experience it's time to convince each and every manager that this could really be a valid alternative for lots of management problems. And I also think accelerators will play an important role in this. The more mainframe related workload we can run on the zBX, the easier it gets to justify this is a really cost effective platform.
That's why I still find it a wrong signal to the customers to put the IDAA on a separate Netezza box. I'd rather have seen IBM waited a bit longer and came up with a really integrated solution. How can you justify to your management you will run DataPower on a zBX and the successor of Smart Analytics Optimizer on a separate box ?
Well, that's it for 2011. Looking forward to 2012 and I hope you will join me in the coming year too.

Sor for those who first still want to have some serious reading material . . .
- I just received the Winter issue of zJournal. You can download it over here. I think it's a great issue this time. It has a comprehensive article on the IDAA (IBM's DB2 Analytics Accelerator). Some personal columns like e.g. from Marcel den Hartog (IT Management) and Mark Lillycrop (Recession Pushes Mainframe prices up). Too much to mention of course but, VSE people, do take a look at the column of Pete Clark who's already listing all 2012 events. And there are quite some articles on CICS like e.g. on the scalability enhancements of CICS TS 4.2.
- Which brings me to the next reading material : the CICS Portfolio eNewsletter that starts off with a 2011 overview. It also gives an overview of 2011 product deliverables, gives you a lot of links to documentation, redbooks, demos, webcasts ... And there's also a preview of 2012 events. You can subscribe to this eNewsletter over here.

Potential DS8700/DS8800 Loss of Access due to repeating device recovery with the PTFs for OA34661 installed on z/Os
In short, people running z/OS 1.11 or higher who are using zHPF and have Release Code 6.2 installed on their DS8700 or DS8800 should read on.
The content of the notification gives you a clear view of what's happening :
"With z/OS OA34661 support and Release 6.2 DS8700/DS8800 microcode, System z High Performance FICON (zHPF) supports additional workloads using QSAM, BPAM, and BSAM access methods as well as provide improvements for DB2 list prefetch processing. These changes expand the type of applications that can now use zHPF, including applications performing format writes. The zHPF support must be in both the host system and DS8000 in order for the new functions to be allowed. In general, the access methods exploiting the new zHPF support do not use format write/update write intermixed in the same channel program. However, Media Manager does have the ability to generate zHPF channel programs with format write/update write intermixes, and the new support for format writes allows it to be done using zHPF. When such an intermix is processed in the control unit using a zHPF channel program, repeating panics will occur leading to fenced host adapter cards and potentially a loss of access issue."
Have a look at the notification page on how to avoid or resolve this particular problem.

Let's move on to the real subject of this post : the IBM DB2 Analytics Accelerator (IDAA).
IDAA delivers even faster response times for your Data Warehouse queries with the Netezza technology. The DB2Night show of last Monday was a presentation by Namik Hrle on this very IDAA and the replay is available over here. If you're even only remotely interested in the technology, it's definitely worth an hour's time. Topics discussed are :
- Business and Technology drivers
- Key design and operational features
- DB2 integration explaining every DB2 parameter, Explain functionalities etc.
- Powered by Netezza
- Supported Workloads
- You can also use the Explain function when you don't have the IDAA yet as a kind of projection tool
- Loading takes about 0.87TB up to 1.5TB per hour depending on the data
- There's a nice slide summing up the conditions for routing queries to the IDAA
- There's a compression ratio of about 4x
- IBM is looking into refining the updating of the IDAA data based on inserts and/or updates rather than whole partitions or tables now.

The first one is IBM Smart Analytics Optimizer for DB2® for z/OS V1.1. This one will be WDFM on December 12, 2011. It will be replaced by the new Netezza solution : IBM DB2 Analytics Accelerator for z/OS V2.1, which was announced along with a lot of other products on October 12 of this year. This complements an earlier announcement with the hardware withdrawal of the IBM Smart Analytics Optimizer (ISAOPT) feature on the IBM zEnterprise BladeCenter Extension (zBX) (ZG11-0350). This also means that this Netezza Solution is running on Netezza hardware and no longer on the zBX. This strikes me as being completely against the entire argumentation IBM built up so carefully in favor of using the zBX as opposed to loosely coupled distributed solutions, no ?
A couple of other softwares being WDFM are :
- IBM z/VM 5.4 on March 12, 2012
- IBM z/VM 6.1 on November 28, 2012
- IBM z/VSE 4.3 on June 25, 2012
- IBM DB2 for z/OS 9.1 on December 10, 2012
- IBM PSF for z/OS 4.3 on September 30, 2012

Fix for APAR PM51655 is needed on DB2 10 for z/OS data sharing environments as a prevention of potential data loss
BM has become aware of potential data loss when running data sharing under any mode of DB2 10 for z/OS.
DB2 10 for z/OS takes advantage of a CFCC/XES performance enhancement by allowing repeated READ CASTOUT CLASS requests to the CF to utilize a restart token and retrieve from the queue where the previous read left off . A defect has been identified in this implementation of the enhanced READ CASTOUT CLASS in DB2 10 for z/OS.
APAR PM51655 will revert the DB2 10 behavior of the READ CASTOUT CLASS to the DB2 V9, and prior releases, behavior.Recommended Actions:
It is strongly encouraged that all DB2 10 for z/OS data sharing customers apply the fix for the APAR PM51655 as soon as possible. The corrective maintenance can be applied incrementally across the members of a data sharing group. A group wide restart is not required.
The ++APAR correction for PM51655 has been placed on the FTP server and will remain there until that time that the DB2 10 for z/OS PTF (UK73864) can be ordered via the normal service delivery channels. Access to the FTP server is as follows:
FTP Server: testcase.software.ibm.comAdding a comment : it's not a straightforward link because you first have to login to the ftp server. If you don't remember your userid : anonymous without password works as well.
Filename: PM51655.HDBAA10 Note:
The file is binary, not tersed.

But when you want some more content, there's the InfoCenter with a couple of entries ('What's New' and 'TSM for z/OS Media Overview'). And for those of you who prefer a .pdf there's the 'Installation and Configuration guide' which you can find over here. But if you want a good introduction, you can take a look at this presentation Bart Claeys (IBM Belgium) gave at the Total Solutions Event in September in Brussels. Mind you, it was still a preview at the time, but I haven't found any more recent, public presentations about this.
For the lazy ones, I mean, for those with limited time, let me summarize some of it. The deal was that TSM V6 was never announced for z/OS leaving many people with sometimes quite large investments in FICON attached material like Tape Libraries and Virtualisation Engines in the cold. So you had to convert to another platform that was not able to connect to your FICON attached equipment.
Well now, TSM for z/OS Media is the missing link between both. You can now migrate to V6 but you can still write your data via z/OS to your FICON attached equipment. The concept is also "designed to allow the tape volume and stored data that was previously inventoried by the Tivoli Storage Manager for z/OS V5.5 server remain accessible on the z/OS system by the Tivoli Storage Manager V6.3 server on AIX or Linux for System z without having to move the tape volume from the z/OS managed tape library" (quote from the announcement letter).
This is a representation of how TSM for z/OS 5.5 operates
TSM for z/OS V5 takes care of
- Database functions: nodes, administrators, policy, tracking of data
- Communication with clients, Admin Center, other TSM servers
- Performs the I/O to FICON (and other) tape and disk
And above is the new situation, with TSM V6 server on AIX or Linux on z taking over most or all of the functionalities of TSM for z/OS V5. But instead of attaching to storage devices, it can also communicate with the TSM for z/OS Media. So you can preserve your previous FICON investments. There are more details in the presentation, for those who are interested.
I'll just give you a quick overview of the migration path
- Install TSM 6.3 server on AIX or zSeries Linux
- Install z/OS media server
- TSM for z/OS 5.5 server move all storage to TAPE
- Extract and Load : TSM utility extracts records from TSM 5.5 z/OS database and loads into TSM v6 database on AIX or zLinux. There is no need to migrate data already written to tape by TSM on z/OS. So you can preserve stored archive (and backup) data avoiding time-consuming migration of data from existing storage pools.
- Begin backups with new distributed server
- Take TSM for z/OS 5.x server off line
Planned availability date : November 11, 2011.

- FAQ : Running Oracle Database 11gR2 on Linux® on IBM System z™ Servers
This is a nice addition to the FAQ I referred to last time focusing on theOracle support for Oracle Database 11g Release 2 running on IBM System z. It also talks about upgrade paths, new features and planning for future patch set updates.
- Flash : DS8000 HyperPAV - Why is there IOSQ time with HyperPAVs
Interesting flash on HyperPAV, why you can still have IOSQ time and how you can detect it from your RMF reports.
- Presentation : IBM z/OS + DS8800 Synergy
This is a very recent prezsentation on System z and DS8800 synergy focusing on three key areas : Performance (zHPF, zWLM and DS8000 I/O priority Manager ...), Business Continuity (HyperPAV, HyperSwap improvements ...) and Management&Growth (1 TB EAVs, Quick Init for CKD Volumes, Dynamic Volume Expansion ...). And ... it comes with the replay of the presentation.
- Workshop materials : zEnterprise zManager Workshop
This is the material from one of the Wildfire Workshops on System z Unified Resource Manager. It's mainly the presentations of course (with or without the speaker notes). Topics covered are : Introduction&Overview, Platform Performance Management and usage scenarios.
- FAQ : zHPF
I think anything you want to know about the High Performance FICON feature is in there : functions, features, prereqs, monitoring . . .
- Presentation : TS1140 Tape Drive and Control Unit DFSMSdss Performance results
This test shows performance results from a "DFSMSdss Full Volume Dump and Restore from disk, with the same amount of data per tape drive, to 3592 E06/C06 vs 3592 E07/C07". It also has a nice 1-page slide comparing the two controllers. The results ? Somewhat predictable ? Yes. The details ? Go and have have a look !

Fix for APAR OA37264 needed on z/OS 1.10 and higher for exploitation of greater than 64 subchannels to a Coupling Facility when running on z196 GA2 or z114 at Driver 93G
A dynamic activate to add a coupling facility control unit configured with greater than 64 subchannels using HCD z196 GA2 and z114 support (OA32576) may lead to system or sysplex outage when the z/OS images reside on z196 GA2 or z114.
z/OS images on a z196 or z114 at Driver 93G connected to a coupling facility on a z196 or z114 at Driver 93G using 3 or more infiniband links that are defined with 32 subchannels per CHPID will exceed 64 subchannels to the CF and may experience the problem described by XES APAR OA37264. The default for IFB links changed from 7 to 32 subchannels per CHPID with HCD APAR OA32576 installed for greater than 7 subchannel support.
When configured as noted above, any dynamic HCD activate which generates a new control unit accessing the coupling facility may lead to the problem. Please see APAR OA37264 which is applicable to z/OS 1.10, 1.11, 1.12 and 1.13 releases for more details.
For installations migrating to z196 GA2 (DR93) level machine or z114, please take one of the following actions:
- At I/O definition time, do not take the default in HCD of 32 subchannels for IFB links introduced in OA32576. Explicitly specify 7 subchannels per CHPID before proceeding with dynamic activation.
- Only define and configure online 2 CF links with 32 subchannels for each coupling facility control unit. Note: 32 subchannels per CHPID will be set by default.
- Apply ++APAR for OA37264 to all z/OS images before exploiting the use of 32 subchannels per CHPID when 3 or more CHPIDs are defined for a CF control unit.
For installations currently configured with greater than 64 subchannels to the CF, please consider all of the following actions:
- Do not perform a dynamic activate to add a CF control unit to z/OS images to use more than 64 coupling facility subchannels per CF control unit.
- If a dynamic activate was performed which created a new CF control unit, do not attempt to bring online more than 64 subchannels (2 CHPIDs). Note: If the z/OS image has been IPLd since the dynamic activate was done the system can successfully exploit the greater than 64 subchannel support.
- Roll ++APAR OA37264 ASAP if greater than 64 subchannel support is needed.
If 64 or fewer coupling facility subchannels are currently defined to each coupling facility control unit, no action is required.

The eye-catcher is of course Windows on zBX, but there's really much more. I'll start by giving you the titles of the announcements, the links and some brief information. Just to tease you for what's coming !
IBM DB2 Analytics Accelerator for z/OS , V2.1 enables a new class of business intelligence and data warehousing workloads for the IBM System z platform (ZP11-0546)
IDAA (yes, we needed another acronym) is the successor of ISAOpt (euh, IBM Smart Analytics Optimizer). It is based on Netezza technology and it should deliver an even far better performance. For the rest, it is implemented as transparantly as ISAOpt for DB2 for z/OS applications. What I find a bit annoying here is that it is not integrated into the zBX and therefore it is not managed by the Unified Resource Manager.
IBM z/VSE V5.1 - 64-bit virtual for future workloads (ZP11-0560)
z/VSE 5.1 is designed to
- "Provide 64-bit virtual addressing for workload growth or new applications.
- Introduce an architectural level set (ALS) that requires IBM System z9 or later.
- Exploit innovative IBM zEnterprise technology.
- Exploit enhanced IBM System Storage options.
- Offer new networking functions for more connectivity options.
- Provide Connector enhancements for high availability".
zEnterprise further extends hybrid computing with support for Microsoft Windows and other enhancements (ZG11-0275)
zHPF enhancements, APIs for the Unified Resource Manager, GDPS improvements and a lot more. But of course focus will mainly be on "Microsoft™ Windows™ on select IBM BladeCenter® HX5 (7873) blades installed in the zBX".
IBM z/VM V6.2 - Accelerate the journey to smarter computing with multi-system virtualization and virtual server mobility (ZP11-0499)
This had been a statement of direction for some time. Well, here it is now : "Multi-system virtualization clustering technology allowing up to four z/VM instances to be clustered in a Single System Image (SSI)". This also implies "Live Guest Relocation to move Linux™ virtual servers without disruption to the business, helping to avoid planned outages"
IBM Tivoli Storage Manager for z/OS Media V6.3 and IBM Tivoli Storage Manager Extended Edition for z/OS Media V6.3 enable FICON attached device access for IBM Tivoli Storage Manager V6.3 Server on AIX and Linux on System z (ZP11-0465)
I like this one as well. It took some time to deliver but it's finally there. Lots of customers were running TSM for z/OS and invested in FICON coupled tape or DASD solutions. But then it was announced that TSM V6 would no longer run on z/OS. So you had to convert to another platform that was not able to connect to your FICON attached equipment. So, this TSM for z/OS Media is the missing link between both. You can now migrate to V6 but you can still write your data via z/OS to your FICON attached equipment. The concept is also "designed to allow the tape volume and stored data that was previously inventoried by the Tivoli Storage Manager for z/OS V5.5 server remain accessible on the z/OS system by the Tivoli Storage Manager V6.3 server on AIX or Linux for System z without having to move the tape volume from the z/OS managed tape library".
I'll just give you an overview of some announcements and give some brief information on them.
IBM XIV Storage System Gen3 offers new 3 TB SAS drive feature (ZG11-0317) and
IBM XIV Storage System Software Version 11.0.1 (5639-YYB) supports 3 TB SAS drives (ZG11-0506)
IBM XIV now support 3TB SAS drives. This increases the maximum capacity from 161 TB to 243 TB. Some limitations : no intermix with 2 TB and no field upgrades from 2 TB to 3 TB. Drive encryption is not supported on these drives.
And, as I've already mentioned before, there's a new, free of charge, monitoring XIV Mobile Dashboard app for Apple iPad devices.
The datasheet on the XIV IBM page has also already been updated.
StorWize seems to have become IBMs showpiece for midsized clients in just one year. There are four announcements (ZG11-0291, ZG11-0516, ZG11-0525, ZG11,0276) covering all enhancements to the StorWize system.
We have additional drives : 3 TB 3.5-inch 7.2k rpm Nearline SAS HDD, 200 GB 2.5-inch E-MLC SSD and 400 GB 2.5-inch E-MLC SSD.
The most eye-catching however is of course the announcement of the StorWize Unified system. V7000 Unified supports NFS/CIFS/FTP/HTTPS/SCP file protocols in addition to existing block protocols (iSCSI and FCP) and is managed through a unified management GUI.
There are also some mirroring enhancements with Low Bandwidth and Storwize V7000-SVC Mirroring.
IBM System Storage SAN Volume Controller V6.3.0 offers enhanced data mobility for high availability and introduces IBM Tivoli Storage Productivity Center Select V4.2.2 (ZP11-0464).
The highlights :
- Lower-bandwidth option for Global Mirror
- Mirroring from SVC to Storwize V7000
- Stretch cluster enhanced from 10km to 300km maximum
Just to put the DS8700 customers at ease, the announcement says : "All features and functions in this announcement are supported on the IBM System Storage DS8700 and DS8800 series". Allthough there are of course some specific DS8800 features. Here's a short overview of what's new :
- DS8800 supports additional expansion frame and over 1,500 drives
- New DS8800 options for 3TB nearline drives, 300GB 15k rpm drives, 900GB 10k rpm drives, and 400GB SSD drives . Oh, by the way, SATA seems to be outdated, you should take about 'nearline' storage now !
- Easy Tier enhancements, including migration across 3 drive tiers and support for thin provisioned volumes . The announcement says : "Easy Tier monitors disk activity in real time and migrates data across tiers and within a tier to optimize performance automatically". I'm not really sure how to interpret this. Is this real time monitoring or is this also real time migrating data across tiers. I thought Easy Tier was constantly monitoring but that it changed its strategy only once every 24 hours. Has this changed now ? I think I'll have to take a closer look at this one.
- I/O Priority support for System z volumes : in fact this is a cooperation between the previously announced DS8000 I/O priority manager and z/OS Workload Manager. Up to now the priority manager was only available for open systems. It now also supports CKD volumes. This integration "is intended to improve disk I/O performance for important workloads and drive I/O prioritization to the disk system by allowing WLM to give priority to the system's resources automatically when higher priority workloads are not meeting their performance goals". Looks promising, no ?
- Larger System z volumes. Volumes can now scale up to approximately 1 TB (1,182,006 cylinders)
- Support for new High Performance FICON for System z (zHPF) enhancements. Amongst others "zHPF has been enhanced to support DB2 list prefetch. These enhancements include a new cache optimization algorithm that can greatly improve performance and hardware efficiency. When combined with the latest releases of z/OS and DB2, it can demonstrate up to 14x-60x increase in sequential or batch processing performance". Mind you, this is only in combination with the new FICON Express8S cards.
- GDPS enhancements for business continuity.

Doing more with less, that is what virtualization is all about. But is your storage following? Does it guarantee high availability, high performance and a quick disaster recovery? Increased user demand has led to unpredictable storage growth. Provisioning storage capacity for new users and applications and achieving optimal utilization has become a real challenge.
The agenda :
How did Kronos put an end to these problems with IBMs virtualization solution Storwize? How do they respond to their needs for disaster recovery? You will learn all about it during this practice session.
In order to optimize your storage, the technique of Real-time Compression will also be discussed.

And then I saw a tweet about this. You can already download this XIV Mobile Dashboard app for iPad from iTunes : IBM XIV Mobile Dashboard for iPad. Well it's such a nice pictures I just wanted to share them with you.
Reading the description, it looks like this is not the full management GUI but just an extra monitoring tool for iPad.
Oh well, more to come next week !

People need this kind of anniversaries to look back once in a while. So I just reread my first post from five years ago. I started out real quiet, not knowing where this would lead me. The first months I had about some 200 readers per month. And it motivated me to keep going. Of course I googled for my blog in the beginning (everyone does, I guess) and I was glad when it finally kept showing up on the first pages. Now, I'm having 200+ readers on a peak day and when people started googling for the last red alert I was mentioned before the IBM site.
Don't get me wrong. I don't want to brag about this. I'm realistic enough to realize only one group of people made this possible and that's you, my readers. So I'll try to keep giving you useful information and keeping you up te date on what goes around in the mainframe world.
So I'm just going to end this post with the same words I posted the last couple of years : thanks for stopping by from time to time and don't hesitate to leave some comments if you have any kind of remarks.
As Apu Nahasapeemapetilon (from The Simpsons) would say : "Thank you, Come again".

- Presentation : Why Websphere Application Server for z/OS
Starting point of this presentation is : "Websphere is Websphere" no matter what platform you run it on. But is that really so ? No, not at all. Websphere Application Server for z/OS is very aware and is using the underlying platform to a considerable extent. So, there might be a couple of reasons why you would specifically want to use WAS for z/OS . . . So, read on, here they are.
- Presentation : z114 Hardware Management Console 2.11.1
"The 2.11.1 Traditional Hardware Management Console (HMC) is new with the z114 Server. This presentation covers the enhanced features and functions of the 2.11.1 Traditional HMC which is available at Driver 93 for both the z196 and the new z114".
- Technical document : DS8000 EasyTier Implementation Guide
This is a DS8000 EasyTier Implementation Guide Using DSCLI with examples. Subjects discussed are Easy Tier Overview, Easy Tier implementation using DSCLI, DS8000 Logical configuration, Data Relocation with Easy Tier Automatic Mode and with Easy Tier Manual Mode.
- Flash : IBM zEnterprise BladeCenter Extension Top of Rack Switch (TOR)
New technology usually comes along with lots of new terminology as well. Well, it's not different with the zBX and here you'll find two documents explaining everything about the Top of Rack Switch and the connectivity with the mainframe.
- FAQ : Frequently asked questions from IBM and Oracle customers about Linux on IBM System z
Nice FAQ that "answers a few common questions about Oracle products running on IBM System z running Linux. This document was jointly written by IBM and Oracle". Subjects are Oracle product availability on the System z platform, Oracle Grid and IBM System z and Technical Support.
- Referral pages :
I'm concluding with some classics that keep getting updated every once in a while.
First there's 'Withdrawal of z/OS Function Beginning with z/OS Release 5 Through Current z/OS Release'. "This flash lists those items IBM has announced intention for removal in a specific z/OS release. These items have already been announced in previous IBM z/OS announcement letters. Consideration should be given to this list when planning your migration to a z/OS release".
The second is the 'IBM System z I/O Feature Reference Table'. This table provides information about System z I/O features and the specific machine types on which they are supported. It is grouped by card type / function: OSA, FICON, Parallel Sysplex, Cryptography, ESCON, and I/O Support.
The last one is the 'IBM Mainframe Life Cycle History' : System z mainframe hardware product marketing and service life cycle history since 1994.

- First of all you might have noticed that the IBM announcement page (Offering Information) has somehow undergone a facelift. Nothing that spectacular, but I also noticed that along with this, all my links in previous posts to IBM announcements are no longer valid. Apparently it's a 'ShowDoc.jsp' that has been replaced by 'ShowDoc.wss' in the link. Damn. Damn. Damn. So, any link to an announcement you click on will be invalid. Fortunately I always include the announcement number. But that's a small comfort. So I might be in for some massive updates. Furthermore, many links in the latest newsletter that was sent out last week will no longer work either.
- I'm proud to tell you that my colleague from RealDolmen Frederik Engelen will be presenting at the EMEA IDUG conference next November in Prague. Subject is 'A DBA's guide to using TSA' (Tivoli System Automation). He's presenting in room Stella on November 16 from 8.30 am to 9.30 am. Abstract of the presentation : "Tightly integrating DB2 with Tivoli System Automation software, IBM added automatic failover capabilities to the trusted HADR database clustering technology. After a quick refresh on HADR, this session will go more in-depth on the inner workings of TSA and its interaction with DB2 to provide you with what you need to know before introducing this in your environment" If you go and see him, give him my regards !
- I'm a bit too late with this one, but there was a Z/VSE Live Virtual Class today on 'z/VSE V4.3 Support of four-digit device addresses'. You can find all information about z/VSE Live Virtual Classes over here. And of course there will be a replay of this virutal class.
- Something completely different : check out this interesting blog post from The Storage Buddhist : '3 TB drives signal the end of RAID 5 / RAID 6'. This has everything to do with the growing size of drives, the growing time to rebuild disks and the conclusion is quite simple : " Either way, the days of RAID5 are just about over and the days of RAID6 are numbered also". Just take a look at it, it leaves me puzzled about this. It's really about making future choices.
- I've written about FAQs before and I think the zEnterprise FAQ is a very nice one. If some one's asking me a question about zEnterprise I always know the answer immediately. Hey, I'm a presales guy, it's my job. Just kidding. So, if you have a question about zEnterprise that's not directly up your alley, this FAQ is the place to go. Or you can ask me of course !

From the first announcement 'Hardware withdrawal: IBM System Storage Tape and Media models and selected features - Some replacements available (ZG11-0248)' I mainly retain the witdrawal from marketing of the mainframe related TS1120 Tape Controller Model C06. This becomes effective November 25, 2011 as it's replaced by the recently announced C07 Model.
There's a second announcement focusing on the 3494 Tape Library : 'Hardware withdrawal: Selected features for IBM TotalStorage 3494 Tape Library - No replacements available (ZG11-0264)'. These withdrawals become effective February 24, 2012. As you might expect, no replacements. And to be honest, I assumed most of these features were already withdrawn from marketing. So, they are now.
If you don't receive our system z e-zine yet, you can subscribe over here. If you have subscribed, but for some reason no longer receive it, please let me know.
The main topics of this issue are the z114, the latest storage annoucements and some words on the cooperation between RealDolmen and Sogeti.
As usual there are also some hints, tips, links, an overview of recent announcements, EOS dates of software and operating systems and an agenda for mainly Belgian events.
Enjoy the reading !

Time goes fast, so I'll try to reconstruct some of the history behind this. The IBM 3494 Tape Library had its built-in library managament functions. When the TS3500 (3584) was introduced for the mainframe at around 2005, it didn't have these library functions. So IBM introduced the 3953 Library Manager with its own frame in which also tape controllers could be built in. It was also used to connect to the TS7700 Virtualization engine. By 2009, the TS7700 could have its own library management functions and did no longer need the 3953. Now, a couple of weeks ago IBM introduced the new 3592 C07 Tape Controller that also has its own library management functionality. So . . . exit the 3953 Library Manager.
This became effective August 9, 2011.

You should really take a look at this list because one can better be prepared. They will of course also pop up on our System z Newsletter. By the way, the new System z newsletter is coming out next week.
Those that drew my attention were z/OS 1.11 and z/OSMF 1.11 (September 30, 2012), CICS VSE 2.3 (October 31, 2012), IMS 10.1 (November 12, 2012) and z/VSE 4.2.2 (October 31, 2012).
Thursday, August 18, 2011
I'll start with a DS8000 announcements with some withdrawals : 'Hardware withdrawal: IBM System Storage DS8000 series select processor memory and microcode features - No replacements available (ZG11-0209)'.
Summarizing all processor memory for the DS8100 and DS8300 models is withdrawn from marketing, effective November 18, 2011.
Next to that 'Microcode Bundle Family - Release 5.1 Bundle Family' is WDFM for the DS8700 and 'DS8000 Licensed Machine Code - DS8000 LMC R6.0' is WDFM for the DS8800. This is effective October 3, 2011.
Replacements : None.

As I always say, just check it out !

Have a nice holiday . . . and now it's time for me to press that very last button :
Thursday, July 14, 2011
Now the mainframe is catching up : 'New IBM System Storage Tape Controller 3592 Model C07 enhances performance and connectivity (ZG11-0211)'.
"Tape Controller Model C07 has up to four 4-Gbps FICON attachments. The Tape Controller Model C07 offers four 8-Gbps Fibre Channel adapters for attaching 3592 Tape Drives, and up to 16 of the IBM 3592 Tape Drives can be attached to a single Tape Controller Model C07. The controller can be installed in an IBM 3952 Tape Frame Model F05, IBM TS3500 (3584) Tape Library frames, and stand-alone racks".The 3952 Tape Drives that are mentioned are not only the TS1140 but also the TS1130 and TS1120 Tape Drives. "An available fibre channel switch feature is required to attach more than four 3592 Tape Drives to the Tape Controller Model C07 (...) The switch may be ordered as a feature on the controller or the customer may supply the switch". The controller also still requires a TS3000 System Console.
The new thing however about this controller is that it comes with library management fuctionality. This means that you no longer need a separate 3953-L05 Library Manager. "For high availability, the first two Model C07 controllers that are connected to a common TS3500 logical library will both have the library management feature. This will allow library activity to continue during code loads and outages on any single controller".
Planned Availability Date : September 9, 2011

We've seen the same with the z9 last year and we've also seen that (to my knowledge) for the first time 'withdrawn from marketing' really meant what it said. We haven't done any upgrades after June 30, 2010. This used to be somewhat different in the past.
Now, it happens in two phases. As of June 30, 2012 any upgrades towards a z10 EC or a z10 BC will no longer be possible. Nor will you be able to do any model conversions or hardware MES features. Roughly speaking this means that any upgrade which involves hardware changes will no longer be possible.
"Field install features and conversions that are delivered solely through a modification to the machine's Licensed Internal Code (LIC) will continue to be available until June 30, 2013" meaning that everything which is in the machine will be able to be activated during the next year. E.g. you will be able to add a zIIP to a z10 EC E12 if there are still engines available in that book, you will no longer be able to add a book. After June 30. 2013 nothing will pass any more.
One point of attention : Capacity on Demand offerings will be usable until their expiration date. Something to check when you're planning to use a z10 after June 2013.
