Storage ROTs
Dear listers, reading Cheryl Watson's last Tuning letter one sentence about the Upgrade ROT caught my attention: Only add resources as needed. If you add more memory than you need, you'll simply cause CPU overhead. My first question is how could more memory cause CPU overhead ? Our production LPAR (z/OS.e 1.4 on a z890) has 5 GB storage assigned; RMF shows an average of 25% of the total frames as active, while the remaining 75% is available. Now and again we have jobs which do need more frames, so the percentage varies to show 60% or 70% active and 40% or 30% available, but that's sporadic. Should I consider the storage assigned to our LPAR as too much ? Any chance that the assigned storage would cause CPU overhead ? I'd like to read your opininion/ROT on this.

Re: V2X2 vs. Shark (SnapShot v. FlashCopy)
Pinnacle wrote: My current client has a V2X2 and is thinking about replacing it with a Shark. SnapShot is used to snap 600 volumes in about 5-10 minutes. The physical tape backups are done from the snaps and take about 8 hours. This DR process is fully tested and works great. My main concern if we replace the V2X2 with the Shark is the DR process. Has FlashCopy improved to the point that you can make a point in time backup and physically move it to tape later? And can you FlashCopy the entire box in a few minutes? If not, the DR process for this client is going to get much more complicated. It is feasible, however FlashCopy is worse than Snapshot. It takes more real disk space, it is slows down the dasd box. PPRC or XRC are not options due to cost. Let me know your thoughts. PPRC need not to be expensive.

The pay extra comes into play if you encounter a previously-unreported and undiagnosed problem in the out-of-support software, for which you unconditionally MUST have a fix (i.e., there is no alternative or work-around).

Re: Just another example of mainframe costs.
I don't want to get too far OT here but http://en.wikipedia.org/wiki/Microsoft_Bob has a good summary of what Bob was, and Melinda (French) Gates' role. My point was that it is easy for the advocates of some product (in this case mainframes) to dismiss the success of some other product (in this case squatty boxes) by saying they're not REALLY any good, they just dazzle the customers with marketing. However, if one looks at Microsoft's admitted failure with Bob, one realizes that even with considerable marketing expertise and budget, you can't sell people what they don't want. If people are buying squatty boxes, it must be because they offer some benefit. And my larger point was that we will not succeed with mainframes by denying the capabilities of other boxes, but rather by recognizing those capabilities and competing with them.

Mainframe vs grid
Slashdot had this article today: http://linux.slashdot.org/linux/07/01/05/0538224.shtml IBM touted 2006 as a resurgence year for the mainframe, but not so fast. At R.L. Polk and Co., one of the oldest automobile analytics firms in the U.S., an aging mainframe couldn't cut it, so the IT staff looked elsewhere. Their search led to a grid computing environment more specifically, a grid computing environment running Linux on more than 120 Dell servers. The mainframe's still there, apparently, but after an internal comparison showed the Linux grid outperforming the mainframe by 70% with a 65% reduction in hardware costs, Polk seemed content banishing the big box to a dark, lonely corner for more medial tasks.

Oh yeah, and D/R tests worked the first time, every time. Steve, Over what period of time were the volumes FlashCopy'd? My understanding is that DFDSS front-ends the FlashCopy function, so you only get the FlashCopy just before DFDSS can do the physical backup to tape. Can you batch all the FlashCopy's, then copy them to tape later? It's very important to keep the time window when the volumes are actually copied as small as possible.

Re: Storage ROTs
An unused unit of storage must be examined, determined that it is unused and actions (statistics) are taken for unused storage. If this storage is just not there, less activity is needed. But there should be less paging and hence reduced paging overhead. There's over allocating and then there is OVER ALLOCATING. This isn't your father's MVS. 64-bit is a big place and changes have been made to how storage is managed - some of which has caused overhead issues. In z/OS 1.8 you can have up to 4TB on a z/OS image - prior to that the maximum was 128GB. Will it matter if you allocate 10GB instead of 8GB... no, but just because your new z9 came with a bunch of extra storage doesn't mean you should give your non-paging 8GB LPAR 30GB.

Re: V2X2 vs. Shark (SnapShot v. FlashCopy)
What is a V2X2? V2X2 is StorageTek (now Sun-Storagetek) disk array. General reference name is SVA (Shared Virtual Array) and the various models over the years have been: IceBerg 9393 9500 V960 V2X V2X2 V2X4 (and V2X4f for FICON attached) We've gone through every model except the V960 at some point over the last seven years. I think STK calls it: Log Structured Array. To me, its description sounded like 'virtual DASD'. I believe they (the WinTel world folks) call it thin provisioning these days. Works great. I have only 2.8TB of physical raw disk in my V2X4f, yet I present 23.1 TB of usable space. Split three ways, I've got 7.7 TB presented to my production LPAR, another 7.7 TB for BCP snapshot copies, and another 7.7TB that is snapshot copied daily and used as a sandbox LPAR. If I was to go and buy disk from some other vendors and duplicate the functionality I have today, I would have to be asking for that 23.1 TB of actual physical disk. It's very important to keep the time window when the volumes are actually copied as small as possible. I snap 926 volumes (almost all 3390-9) in about 1.4 minutes. We dynamically create the snap JCL each morning right before our syncpoint with a rexx routine wrapped around a dcollect report. This way name and allocation changes are automatically picked up (one less possible human error potential). With the automated IMS/DB2/TSO/etc down and up processes, the whole syncpoint runs about 2.5 minutes. PPRC or XRC are not options due to cost PPRC need not to be expensive. Obviously it requires two dasd boxes and link, but gives you much better RTO and RPO. We just replaced our tape based backups (which were taking about 3.5-4.5 hours with 9840's, HSDM, and ExHPDM) with a PPRC solution. HUGE reduction in RTO as the 1-2 days it was going to take to ship the tapes to the hot site was simply eliminated. The 4-5 hour restore from tape time was also eliminated as the data is sitting on another V2X4f at the hotsite ready to go. Last DR test we were IPL'ed in under an hour after arriving at the local recovery center. The RPO only lost a few hours (the difference between the time it took to create the tapes verses push the data across the PPRC link) and is still about 24 hours since we only take one syncpoint a day (after batch), but we are looking at adding another in the pre-batch lull time. We'll probably take a hard look (I'm hoping) at a GDPS solution as well since it would be the next logical step.. but I fear the costs may simply be too high for management to bear - even with the promise of zero down time. Most expensive ongoing cost of the PPRC solution was the link cost. But we manage to do it with a tiny DS3 by snapping the BCP sets throughout the day and sending changes across the link. That way, when it comes to syncpoint time, the amount of change data is very small and the DR set at the remote site is set and stable and ready for recovery just 10-15 minutes after the snaps (keeping the RPO close to that 24 hours) Jeffrey Deaver, Engineer Systems Engineering [EMAIL PROTECTED] 651-665-4231(v) 651-610-7670(p) -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: Mainframe vs grid
I read the article and it did not contain any information concerning the size of the mainframe that is being compared to the grid. I have seen detailed analysis of grid computing versus the use of a parallel sysplex in z/OS and the z environment compared favorably when using its capabilities. This article talks about the mainframe using VSAM files and some IMS. It seems to me like they needed to be using less VSAM and more IMS, perhaps FP to get the throughput that was required. The mainframe has plenty of options for processing large amounts of data in parallel -- similar to what this customer achieved through the use of a grid -- that provide for faster response time. Also, this article mentioned that the application changes were difficult and time consuming and that the newly written application could handle changes more quickly. This too could be handled with good application design on the mainframe. So -- what is your point -- this appears to be a project where everyone was comfortable with the programming environment of a grid and developed an application that maximized it strengths to produce a good result for the client. That is great for the client. My caution is to take this article and imply that anyone else would achieve the same result by using the same technology and that the same result could not be achieved using a mainframe. How about some basic math on the numbers presented -- one mainframe versus the grid of more than 120 Dell servers to produce an application that finished in 65% less time. Did they compare the cost and performance of three mainframes loosely coupled as a sysplex to determine what the performance would be? Let's see, three versus 120 and the three could probably outperform the 120? Don't get me wrong, I know that it is easy to second guess a solution. However, this company spent a lot of money on the completed solution. The article even says that money was in third place on their priority list. So, cost of the solution did not rule out the mainframe. It appears from the article that a single mainframe does not scale as well as 120 Dell servers. I think I could have made that leap of faith without an elaborate test. I walked away from the article with the impression that good technicians on this project did not want to use the mainframe and developed a good solution without it. However, this does not tell me that the mainframe could not have done this job equally as well had the project been composed of mainframe technicians that knew how to make the environment scale and perform equally as well as a grid. Just my bucks worth. So many words could not be worth two cents, could they? Tom Moulder snip Slashdot had this article today: http://linux.slashdot.org/linux/07/01/05/0538224.shtml IBM touted 2006 as a resurgence year for the mainframe, but not so fast. At R.L. Polk and Co., one of the oldest automobile analytics firms in the U.S., an aging mainframe couldn't cut it, so the IT staff looked elsewhere. Their search led to a grid computing environment - more specifically, a grid computing environment running Linux on more than 120 Dell servers. The mainframe's still there, apparently, but after an internal comparison showed the Linux grid outperforming the mainframe by 70% with a 65% reduction in hardware costs, Polk seemed content banishing the big box to a dark, lonely corner for more medial tasks.

Hats off to prior R.L. Polk worker.
I can tell you that we got one of the best systems programmers that I have ever seen from R.L. Polk about 30 years ago. He has since retired. He did a number of amazing things such as front-end SVC 26 to keep a certain tape drive range from being used, SMS before there was such a thing, Mod on IEBCOPY to help with enqueues that IBM didn't attempt to address until PDSEs, wrote his own cpu tester to help verify CPU changes from model to model and how it would impact our shop, disk performance test that would expose companies that would pre-stage data to get better performance numbers. Wrote in house scheduling package that used a usercat to store all of the information (lasted for about 12 years). Just a small list of his giant contribution to keeping us running smoothly and efficiently. My entire view of what makes a good systems programmer was shaped by watching him do what he did.

Re: Special characters in passwords was Re: RACF - Password rules.
Characters like slash used in a password conflict with the parsing routines used for e.g. LOGON APPLID(...) DATA(...). Who knows where all there is parse-like hardcode of sessiondata. And then there is the security system password prompts where today slash after pwd means new pwd. I try to avoid working in snake pits. On the other hand there is way to have 10 character pwds.

Re: Just another example of mainframe costs.
Charles, That is exactly WHY the z9 can be cost effective in the right circumstances using Linux under z/VM. Heck, even z/OS competes well today against WebSphere/UDB under AIX with the advent of zAAPs and zIIPs. MOST UNIX software is licensed on a per processor basis. Those license costs add up quick on 16-, 32- and 64-ways. Even with micro-partitioning and sub-capacity pricing, the issue remains because of the prevailing one app per server mentality that is so widespread in how they provision their boxes.

Re: V2X2 vs. Shark (SnapShot v. FlashCopy)
My current client has a V2X2 and is thinking about replacing it with a Shark. SnapShot is used to snap 600 volumes in about 5-10 minutes. The physical tape backups are done from the snaps and take about 8 hours. This DR process is fully tested and works great. My main concern if we replace the V2X2 with the Shark is the DR process. Has FlashCopy improved to the point that you can make a point in time backup and physically move it to tape later? And can you FlashCopy the entire box in a few minutes? If not, the DR process for this client is going to get much more complicated. PPRC or XRC are not options due to cost. Let me know your thoughts. Tom, we have a lot of experience with all the various vendor's instant replication functions, since we support them all in our FDR INSTANT backup product. In our experience, the elapsed time to do the SNAPSHOTs and the time to establish the FLASHCOPYs is similar. In both cases it takes only a few seconds per volume (your milage may vary gr). The big difference is the architecture: The STK disks use a virtual architecture, so that the SNAPSHOT is just a matter of copying pointers in a table. The snapped copy takes up no more space on the back-end disks, except for tracks that are updated. The virtual disk data is compressed, so it takes up less back-end room than the actual data would require. The IBM and HDS disks copy the data in the background when a FLASHCOPY is done. The ESTABLISH may be quick but the background copy may take a while, especially if you FLASH many volumes. The FLASHCOPY architecture makes the flashed copy look like the original disk immediately so you don't need to wait for the copy to complete, however, your performance may suffer if you try to do the DUMP before the background copy is complete. EMC SNAP actually supports both options. TIMEFINDER/CLONE does SNAP to real volumes, similar to the IBM/HDS Flashcopy. TIMEFINDER/SNAP does SNAP to virtual volumes. These are not really like the STK virtual volumes, but they do only copy tracks which are updated on the original disks. In our experience, TIMEFINDER/SNAP can be slow, but TIMEFINDER/CLONE is better. | Has FlashCopy improved to the point that you can make a point in time backup and physically move it to tape later? FLASHCOPY has always supported this. FDR INSTANT has done this since IBM Flashcopy first came out. -- Bruce A.

Re: Just another example of mainframe costs.
Without knowing what your day-to-day role is, it's hard to say. First, simply by not being in denial. Mainframes are not better because the people who use them are older, the boxes are bigger, they were around in 1979, and all of your professional peers work on them. Mainframes are not better because we all know they're better, and that's that, and anyone who disagrees with me is obviously one of them. Second, many of the participants on this list, myself included, work for (directly or indirectly) IBM or a software vendor. We have a direct or potential influence on speed, cost, ease-of-use, reliability, and security. If you work for an end-user company, then you have some influence on, for example, the ease-of-use of your systems. I often hear on this list a defense of obscurity: why would you want to change how JCL works -- it was good enough in 1968, it's good enough now. That is not a productive attitude. Face it, the mainframe is in many ways user-hostile. We are the people who invented the cult of the unapproachable IT guru: authorized personnel only. Changing those attitudes would be a good step. And some things cannot be changed. Better to work to advocate intelligently for the use of mainframes for the tasks they are good at, than to operate in denial of the fact that it's not the best choice for every computing task, or every company.
