Re: Problem fetching a program object (CSV031I)
what does AMBLIST tells you about patched module. Nothing one should care about I've also compared the listings of AMBLIST (patched and unpatched module) and they just differ in the hex-listing (only at the expected locations). Why don't you use AMASPZAP for such kind of patches? Well, now as I fight with this stuff for some days, I really think I should try to argue our management that we should use AMASZAP. The problem is, that the bytes we have to patch are on different byte offsets with every release - so we also have to create new control cards for AMASZAP for every release. Currently I wonder if it is possible to 1. build our application, 2. analyze all needed program objects 3. find the offsets to patch 4. write control cards for AMSZAP I guess this would be fewest pain for all ;) Bye, Michael -- 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

Surely, it's not track capacity. Where can I find further information (some RTFM) ? The maximum number of physical blocks (CKD) on any given device has always been the number of blocks with key length 0 and data length 0. For many years now, even if you specify data length 0 the control unit would write one byte on the track in the data field. But originally, if you asked for X bytes in the data field, you would get X bytes on the track at that location. Some time in the 1980s (I think), IBM began recording data on the track not in bytes but rather in units of some larger size, possibly called chunks (at least by me). The size of the chunk has varied from device type to device type. Using units of chunks allowed for greater levels of error detection and correction. The 3390's chunk size is around 34 bytes, I think. No matter how many bytes you want in your data field, 12 more bytes are added by the controller for a 3390 track (I think it's 12). So the smallest amount of data, a data length of 0, requires the controller to add 12 bytes, which requires one full chunk. Any data length between 0 and 22 will result in one chunk on the track. Any data length between 23 and 56 uses up two chunks on the track. And so on. Besides recording data in chunks, inter-record gaps have also been required on real CKD devices since day 1. There are plenty of other gaps on the track also, such as immediately after the home address and after each count field. All this overhead reduces the amount of space effectively available for user records. All this overhead is now unnecessary, since real devices are FBA and not CKD, and the control unit maps virtual to real when writing and real to virtual when reading. The internal real device's characteristics can literally be anything, and some day they may even be replaced by bunches of atoms instead of magnetized areas on rapidly spinning platters. The controller just has to know how to do the mapping. Our software back in the mainframe has to conform to what the access methods require, and they still require adherence to the ancient physical CKD limitations. Now if you want to know why the gaps were required since day one, that's another story, and equally fascinating (at least to me). :-) Bill Fairchild Franklin, TN **See AOL's top rated recipes (http://food.aol.com/top-rated-recipes?NCID=aoltop000304) -- 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

ATS STAR question
Hello list, We are planning to use ATS STAR to share our TS7700 tape units among our systems. The main reason is a problem specific to the TS7700 (and probably other VTSs) that did not exist in our STK physical tape environment: when a system goes down (for whatever reason) and it had tapes mounted, these tapes remain mounted on the TS7700 units and are therefore not available to other systems. The only way to get the tape available again is to dismount it and that can only be done from a system that has the unit online. We started our initial TS7700 configuration with tapeunits dedicated per system, because the TS7700 provided more than enough of them and we could drop our MIA tapesharing software. But soon we found the problem that tapes could only be dismounted by the owning system and if that system was down for a longer period (software problems, hardware maintenance, scheduled unavailability of testsystems), the mounted tapes were unavailable for that period. The obvious solution was ATS START tapesharing. In this situation, a tape mounted by a disappeared system can be dismounted by another sharing system. Chapter 16 of Setting up a Sysplex describes sharing tapeunits in a sysplex and explains how sharing in a sysplex works most optimal. This does not cover the situation that a tape mounted by a testsystem can be dismounted when the entire test-sysplex is down. The last paragraph of chapter 16 suggests that tapeunits can be shared by systems outside the sysplex, either supporting ATS STAR or not. This sounds reasonable, since the ASSIGN is done when a unit is allocated for AS units or at vary online for non-AS units and so serialization is guaranteed. See ATS STAR APAR OW50900 for details. My question is: Does anybody share ATS units over sysplexes and does this work? What happens when a system allocates a unit and that unit is assigned to a foreign host (AFH)? Does allocation go through allocation recovery and select another unit, or does it wait for the device to become available?

Re: WLM question.
Ted, I'm with you on SU, mostly. I like percentage, it's what you see in SDSF and is easier to describe back to the user (and their demanding managers). I find SU useful, but constricting, particularly because our sysplexes invariably consist of different models of machines and trying to limit application X to 1% of the CPU becomes an exercise in frustration when the application is required to run on at least one image on nearly every CEC at the same time. I think SU would be more useful if you could specify it by system/image, for a single application with the same name. Say you have an application named HOG on 6 systems, and you want to limit it to 1% of the system at max on a per-system basis, and you know that it is the only workload running in the SYSHOG started task service class. It would be nice if I could limit it then, on SYSA to 100 MSU, on SYSB to 300 MSU, on SYSC to 180 MSU, SYSD to 40 MSU, SYSE to 65 MSU, and SYSF to 420 MSU. But instead, I have to either make six service classes and six resource groups (what a waste of CPU to have to traverse all that), or simply allow that any one of them might get as much as 6% of the largest box it runs on (unacceptable). SU is also painful in Batch and TSO periods. I want first period TSO to last a quarter second. Real time. Not SUs. And I want my WLM policy to apply equally to all systems (across more than 12 CECs) and all images. And I want my low batch to sit in first period for 30 minutes before dropping lower. The same way on all systems. SU doesn't seem to allow that either. It becomes an approximation, that we constantly have to review and update to keep it accurate. Percentages are better, in disparate sysplexes, if you ask me, but SU still has it's (very limited) uses in an overarching standardized policy (which is much easier to maintain than having multiple policies for each plex). Still, I wish the new percentage system could allow different percentages for different images in the same resource group. Ah well. At least having percentages is a step forward, and a welcome one at that. Do you know if there has been some update to WLM to address image-level resource groups that I haven't seen in the books?

Re: GPL and z/OS (was: Java Problem Analysis)
Timothy, I agree, except: 1) Its not simple :-) 2) The ported tools and toys are not released by IBM as a product. I still don't believe that IBM has released any GPL-licensed z/OS tools as products.Probably my fault... it would have been more clear if I would have said supported products. IMO, this is one of the big problems with z/OS Unix other *nix implementations include a much better set of tools, such as the GNU tools. Take for example bash. This is the most popular *nix shell, licensed under GPL, but it is not included with z/OS.Other *nix vendors ship their systems with a nice set of tools, and either fully support them, or in some cases have a managed support clause which is something less than full support. See for example: http://www.sun.com/software/solaris/freeware/ Where, you will notice that many of the open source GPL tools are listed as managed support: m = managed: Sun provides existing patches and escalates new bugs to the developer community. Compare this to the z/OS Unix tools and toys... they are woefully incomplete and out of date.

And I never have to change them again based on a machine upgrade. I guess that's were I disagree. I use resource classes based on a min/max of service, rather than processor capacity. I set it up, now and never change it. Regardless of the processor capacity, my TEST workload will never get anymore than it had. With my choice the test workload will never get any more resource. With yours, it will grow with each upgrade. Plus, it doesn't work with multiple CEC's (differing capacities) in the same SYSPLEX. Plus, I have a question. Why do you want to give more resource to the unimportant workloads, just because you've done an upgrade? My service classes are loosely structured around a Development - Test/QA - Production scenario. It's loose because I allow things to cross the line. Really important Test/QA stuff can run in a low production class. We aren't SYSPLEX (yet), so I don't have those concerns (yet). I'd expect there to be challenges in making this work in a differing capacity multi-CEC environment. But I'd also expect the move towards minimums and maximums based on percentages of capacity would work better in those environments. When our business grows, it's generally the whole business. We don't see localized pain points. Not that it can't happen. I set up resource groups around the Development and Test/QA service classes to ensure a minimum service of around 1% of the box capacity. When things are busy, these JOBs creep along, but they keep moving. And as resources free up, they can be devoted to these JOBs. But these JOBs can't interfere with production work beyond a certain point. The lower Development classes have a maximum service of about 3% of the box and the next two bottom classes step up to 5% and 7%. Production classes have no minimums and are not capped. We have a couple high performance development classes for short programmer JOBs too, but those have CPU time limits associated with them. This isn't a hard and fast rule either. When we upgraded to the z9, I didn't just carry over a straight percentage. I gave the minimums a little more, but not a full measure of the capacity increase. I gave the maximums the full percentage increase. We're running sub-capacity too, so the MSU floors and ceilings I've defined aren't truly those percentages. But it seems to be a good guideline. Not perfect, but workable. Our business changes over time too. As needs change, the WLM policy has to change to meet those needs. I have only made minimal adjustments for some new JOBs since the z9 upgrade. WLM gives you a lot of options. No two sites are the same. Work out a structure that works for you and adjust it as you see fit to address your needs. Then adjust it again as your needs change. I doubt you'll be able to find a policy that works now and forever.

Looking at performance / reliability /encryption facilities ... so on... any decent write-ups out there ?? Here is a little summary from Fred Moore. Just one of Fred's claims to fame is that he was the first systems engineer at StorageTek. The Sun (was STK) drive is faster at 120MB/sec than the 3592 at 100 MB/sec. and customers like the speed. Both offer RFID for Iron Mountain like services and have a 30 year media life, far too much since the technology will obsolete well before then. Capacities are equal at 500 GB and both compress to over 1TB/cart. The 3592 has a max. rating of 20,000 loads and unloads versus 15,000 for the T1 making it 33% more durable in an automated library. To get encryption, IBM and Sun require existing Escon/Ficon tape products to be replaced. This could be expensive and causes encryption appliances and CA's mainframe ZiiP host software encryption product to be considered. These are tape drive agnostic and a few still affect the ability to compress. Bottomline: the products are close with performance the biggest differentiator and the price you pay is based on your sales rep and negotiation skills. Conversion costs need to be carefully evaluated. Other key factors to consider are Sun's ongoing committment to tape. Sun is not 100% focused on tape (or storage) as STK was. Sun has taken STK from years in 1st place and innovative tape leadership to 3rd place in the tape industry in just 1.5 years. They have laid off considerable of storage talent, key tape and virtual tape architects in the past year to save money. Sun spends less than STK on storage marketing.This raises concerns about future developments, schedules and roadmaps.

Re: Max. number of physical blocks on 3390 track
Bill: Another excellent explanation and addition to all of your previous posts. I know I gasped when I first looked at the formula calculations from RDC but a little time spent in understanding it proved to be worthwhile. Thanks Bill Date: Thu, 20 Dec 2007 13:22:47 -0500 From: [EMAIL PROTECTED] Subject: Re: Max. number of physical blocks on 3390 track To: IBM-MAIN@BAMA.UA.EDU In a message dated 12/20/2007 12:06:21 P.M. Central Standard Time, [EMAIL PROTECTED] writes: You can also get the formula calculations retruned from a Read Device Characteristics command to the storage controller. What is returned are the various constants that must be plugged into the formula and some flag bits that tell what to do with some of the constants. And I forget who said it, but the vendor hardware manuals will describe whats in the gap. One item is repeated skip displacement information, if a track was assigned a skip due to a faulty area of the track. The skip displacement information is always in the gap. If no skips have been assigned, then the skip displacements stored there reflect that no skip has been assigned. This is another aspect of error detection and reliability that has evolved over the decades. The first device with skip displacements had only one, and the 3390 now has seven. What is recorded in each 2-byte-long skip displacement is the relative number of the chunk on the track, beginning with index point, where chunk number of bytes are skipped over in reading and writing.

zFS Recovery via APAR OA22351
Apar OA22351 introduces an option to allow zFS to temporarily remount a R/O file as R/W so that it can rerun the zFS log. Normally a R/O file does not change, but if it is mounted R/W for maintenance, for example, and is not properly closed down, it may not be able to be mounted R/O and has to be remounted R/W to do the recovery. OA22351 allows this remount to be dynamic and automatic so saving an IPL to fix the problem.

Re: Tape/Cart drives
Mike Baldwin wrote: [...] Here is a little summary from Fred Moore. Just one of Fred's claims to fame is that he was the first systems engineer at StorageTek. The Sun (was STK) drive is faster at 120MB/sec than the 3592 at 100 MB/sec. and customers like the speed. Speed can be misleading. The benchmark show maximum possible speed - that requires environment optimized for the test. For example data cannot compress to poor or to well (!). Been there, done that. However real-life speed is never optimal. In such case it is important that both drives can slow down. However, AFAIK both use different approach for that. Size of buffer can be also a factor. Both offer RFID for Iron Mountain like services and have a 30 year media life, far too much since the technology will obsolete well before then. As now, very few applications/components of z/OS utilize RFID. AFAIK DFSMShsm uses it for WORM carts *only*. What's important, RFID on STK is not visible to z/OS !!! At least HSM-RMM-z/OS. Capacities are equal at 500 GB and both compress to over 1TB/cart. New 3592E05 aka TS1120 with new EEETC cart has 700/2100 GB per cart. That's more than STK has. The 3592 has a max. rating of 20,000 loads and unloads versus 15,000 for the T1 making it 33% more durable in an automated library. To get encryption, IBM and Sun require existing Escon/Ficon tape products to be replaced. In both cases encryption is fee-based feature. In both cases only the newest models support it. However the implementation is completely different. What's better ? I can't jugde, but if one is interested, he should learn deeply about it. This could be expensive and causes encryption appliances and CA's mainframe ZiiP host software encryption product to be considered. ...and IBM has product (Encryption Facility, AFAIK) which uses crypto hardware. I believe it's even faster and doesn't consume neither MVS CP, nor ZIIP cycles. Caution: encryption at host level means compression at drive level is almost completely ineffective. Encrypted data tend not to compress. This is a cost - media usage, speed. [...] My $0.02 Regards -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.

Re: zFS Recovery via APAR OA22351
My question is why the default for this option if NO and not YES, and, for that matter why would you ever not want the recovery to happen automatically? Just yesterday I was reading a forenics paper on analysing a journalling filesystem (ext3 as it phappens). In my case the interest is in data recovery rather than investigation, but the data carving techniques are largely common. There is a lot of useful info in the journal meta-data - running the journal causes most of it to be lost; even a (non read-only) mount. I expect similar issues apply to zFS.

Flushing SMF Records from Buffer
Is there a way to flush SMF records from buffer to immediately write to DASD? Currently, we have to wait for 15-30 mins before we can access the SMF records. I knew that we can access SMF type 70-79 using RMF JCL and produce reports from the bufferspace, however for CICS and DB2, we can't do that. We need this requirement to immediately access the SMF records for problem determination. Btw, can we use REXX to access the bufferspace? TIA.

PR: New Videos on IBM TV about IT Costs
There is a new series of videos posted to IBM TV that I found interesting. First, start here: http://www.ibm.com/software/info/television/index.jsp Click on the Select a topic button, then choose either Systems Storage (or Software) and navigate to the System z - All media types section. You'll then get a list of videos. Several are interesting, but look for the Scorpion series and start with part 1 if you want to view the cost-related ones. One thing I actually disagree with slightly in Part 1 is the speaker's statement, Everybody knows the cost of their mainframe software, as if it's a fixed given. That may be a U.S.-oriented perspective perhaps, or perhaps it was an oversimplification for a short video. But I've met a lot of customers that have many misperceptions in this area, and many do not manage their software portfolios optimally. That's regardless of platform. Software mismanagement includes not optimizing what you've got for cost, and not keeping the portfolio in line with current needs. In simple terms you buy software to avoid labor. Theoretically you could buy a machine and hire your own army to write an operating system, middleware, tools and utilities, etc. When computing first started, that's what you had to do. It's expensive, so almost no one writes all their own software. Even big software companies like IBM, Microsoft, and Oracle with seemingly endless programmer resources still buy lots of software. But where you draw that line (between buy and build) varies and will likely change over time as labor costs change. Typically that line should move up over time, because typically labor costs are increasing, and the ability of software vendors to spread those costs is increasing, especially due to international software market expansion. That's a universal pair of trends, not platform-specific. Balanced against that is the fact that your own software code is your business because it's just for you, so you don't have to modify your business to match more general-purpose software. Which is yet another reason why Service-Oriented Architecture (SOA), to meld your own software bits seamlessly with the commercial stuff, is so important, but that's a topic for another day. The correct answer may be, given these trends, Buy more software, but optimize well. On the buy more side, I generally favor looking first at application developer productivity, because that's where you'll find significant IT cost. That's also where business benefits result, if developers can deliver quicker and with higher quality. I get very concerned with organizations where this software line in the developer productivity area hasn't moved in 20+ years: that's often a big warning sign that there's mismanagment. Anyway, I found the videos interesting and pass them along. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- 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

Unless you specifically code an AFH unit in JCL, the system will look at all possible devices that can service the DD. AFH devices are weighted lower than unallocated devices. The system will choose one of those first. If there are no devices available, allocation recovery gets control.
