Re: Z/OS Maintanance
I also have been working with MVS since before (just) 1980, and I can honestly tell you that the correct answer is It depends. The important part is to actually do the maintenance and not get (too) far behind. There are a lot of sites that tend to get several releases (years) behind and then they end up calling me (or someone else) to get them back up to date. The important thing is that you do some sort of maintenance on some sort of schedule. The IBM REDBOOK pointed to previously in this thread is actually very good about giving hints on how you should perform the maintenance aspect of our Systems Programming jobs. Maintenance used to take a REALLY long time, and now it's actually fairly simple. There are a lot of factors to consider and the more complex your site, the higher the difficulty level in keeping relatively current. You really have to plan your system for the method you choose. There are those that feel that they can apply maint on a fixed schedule, and if that works for them then that is fine. There are others that believe that you should install a new release once a year (or two) and only put on maintenance that you absolutely need in order to fix a problem that you are experiencing. That's fine as well. What ever you decide, it will be great for you and your site. Personally, I like the method of installing a new release periodically and applying the current maintenance (as needed), and then doing all (or most) of the hyper fixes in between. It's a little more work, but it tends to work out good for me. I don't have a fixed schedule, but I try to keep the sites that I maintain at about the same level. There are quite a few. My reasons are because if I run into a problem at one site, I can be proactive and fix it for the others as well. It's terrible to admit, but this way I look really good because the ones that reported the problem are happy that I fixed it for them, and the others are totally thrilled that I was looking out for them. It's sort of a win-win thing, but I have to admit that it is a little more work on my end to keep everyone relatively equal. Also, by equal, I don't necessarily meant hat they are even at the same release, I maintain sites from 1.4 (unfortunately, and until recently I still had several OS/390 sites) ) to 1.12, but (where I can) they are all at the same level of maintenance. Most fixes are applied back to the older releases (as long as they are supported) so it's not as hard or as complex as it might seem. I try to keep them all as current as possible, but not all of them want (or need) to be on z/OS 1.12 so I try to be as flexible as possible, while keeping them all current (as much as possible) with maintenance. I urge you to find a way that works for you and try to be flexible. If you find that you need to change to meet the needs of your site, don't say no just because it doesn't meet your schedule of maintenance. Try to be a service to your site and try to be as accessible as possible. The old days of the wall between systems and the rest of the site are long gone (or should be). I miss them sometimes, but not very much. :) -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: CFSIZER?
Barbara, not to escape your question about CFSIZER, but if you are migrating from one CF to the other, meaning there will be a timeframe when both of them are online, then moving the structures through rebuild (or better REALLOCATE) will manage this for you. During rebuild structures are allocated by count which means that the CFLEVEL17 structure will be allocated large enough to contain the same number of objects currently contained by the CLEVEL15 one. Checking the actual CFLEVEL17 size and updating the CFRM policy accordingly will complete the job. Also, when moving to CFLEVEL17 don't forget that the size of the CF Control Code itself increases significantly. From some 100 MB to some 500 MB if I remember correctly. The CFCC LPAR memory definition should be updated to accomodate this.

Re: Enclave help
AFAIK, there's nothing available within z/OS itself to cancel an individual enclave, although I certainly have wanted that capability sometimes. This makes sense when you think about what enclaves are: they're really sub-tasks from an address space more so than being their own address space. So the correct answer is that to get rid of an enclave, you have to cancel the unit of work from the task that owns the enclave, in this case, apparently DB2. You can change the service class of an active enclave, maybe to keep it from consuming resources. But a couple of caveats: 1) Beware dependent enclaves as changing the service class of those will effect the owning address space. I've seen CICS create dependent enclaves and you don't want to touch those. 2) For DDF work that's running on the zIIP, if you're thinking to change the service class to one with a Resource Group cap to keep it from consuming zIIP resources, that probably won't work well as work on specialty engines don't accumulate SUs towards RG caps. At least that what I've been told, and that's what I've generally seen. Finally, since this is DB2, we recently ran into a problem where QMF DDF threads wouldn't go away: they couldn't be cancelled from DB2 and seemed to be stuck looping. Turns out there was a bug in one of our DB2 monitoring products (from IBM, no less) that was keeping them from going away. This was somewhat problematic because of point #2 above: they thread was consuming zIIP resources that other threads could use. To try to resolve this (at least partially) I put it in my SC with a RG cap of 1 SU, varied the zIIP off line to get it on the GCP, then put the zIIP back online. This seemed to slow it down, although I'm still not sure why it worked as well as it did: I expected it to bounce back to the zIIP and run away again in short order. While it did bounce back to the zIIP, it consumed at a much lower rate than before. Again, I don't have an explanation, I only relate the experience in case you're stuck in a similar situation, maybe it might be something to try. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
How many CPU seconds can I consume per 10minutes?
Background: Traditionally, we have been reporting cpu usage for our box normalized to 100% using the TYPE70PR SMF records. Unfortunately, when the model of the box changes via CoD (or whatever it is called), you cannot even *see* that the capacity has become bigger. Using the total cpu seconds consumed, what you can see is that more cpu seconds were used in the same length interval, either because the number of processors increased or because the processor speed increased. So I have been thinking of doing the 'cpu usage per box' graphic using total cpu consumed in each interval. Which raises the question what is the limit of cpu seconds per interval? Because that is what I need to show management to show how much more we would have needed. We are running on a sub-capacity machine (and our new one will also be sub-capacity, meaning slower processors). So obviously I cannot use 60s*10*no.of.cps to determine the limit, since we will not achieve 600s cpu on one cp per 10minutes for general cps. I think. In addition, I wanted to avoid conversion to MSUs or MIPS (since I am always telling my management that those are meaningless). But for the new machine zPCR was done for our workload by IBM. In the comparison the actual MIPS of several z196 models were downgraded in their number of MIPS (to account for lpar overhead and workload mix, IBM calls it zPCR MIPS). Which seems to confirm my thinking above. So my question is a) if my thinking above is correct or flawed (and please set me straight if it is flawed). And b) how do I determine the maximum number of cpu seconds I can have in any 10-minute-interval at 100% load on the general cps? (I did search the archives, but did not really find anything that might be relevant.)

Re: PROBLEM COPYING PDS MEMBER TO A PANVALET LIBRARY
My guess is that a previous IEBGENER/COPY or FileAid attempt changed the file attributes, or overwrote a control block at the beginning of the Panlib. The other posters are correct in that there are special Pan* programs to add members (or even whole PDS files) to Panlibs. If you have the Panvalet subsystem installed, you can treat Panlibs sort of like a PDS, and that may be useful for some people. *don* On Mon, Jul 4, 2011 at 7:55 AM, esmie moo esmie_...@yahoo.ca wrote: Lizette, I tried using the ISPF Panvalet utility and encountered the problem as well.

Re: PROBLEM COPYING PDS MEMBER TO A PANVALET LIBRARY
Panvalet does not use a PDS to store the data. I have extensive experience w/Librarian. Librarian had a SUBSYS feature which allowed the Librarian file to be accessed as thought it were a PDS. The general rule was to refer to the Librarian dataset with SUBSYS=xxx (usually LAM...

Re: Trapping the LPAR Deactivate signal on z/OS?
From the z/OS 1.11 annnouncement (209-242. Dated Aug 18, 2009). The sysplex failure management (SFM) component of XCF used in a Parallel Sysplex to manage failures and reconfiguration has been enhanced in z/OS V1.11. It is now designed to use new Base Control Program internal interface (BCPii) services to determine whether an unresponsive system has failed, expedite sysplex recovery by bypassing delay intervals when possible, and automatically reset failed systems without manual intervention. This new function is expected to allow SFM to avoid waiting for a period of time before assuming that systems have failed, improve the responsiveness of failure management, avoid operator intervention, and help limit or avoid sysplex-wide slowdowns that can result from single-system failures. Just to clarify, BCP/II is a mixture of HW/SW that allows communication with the HMC. I think the plumbing you need is already in place. Just needs to be accessed. HTH, snip I've been discussing the idea of whether it would be possible/useful to write something to trap the hardware LPAR deactivation signal and use that to trigger an controlled emergency shutdown of z/OS. On VM and VSE, there is a trap present in the base OS that grabs that signal and starts a controlled shutdown of the OS (you can simulate it using the SIGNAL SHUTDOWN command on VM). z/OS doesn't seem to have any knowledge of this and proceeds to die horribly when the timer specified on the deactivate fires and the hardware goes away. /snip -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: Real return address for link and attach
Donald, You seem to be asking about what happens to the real R14, is that correct? How do you define real, If you are asking where the contents of R14 at the point the LINK(X) or ATTACH(X) macro is issued in the calling program are stored, the answer is simple, they aren't. Both of these macros (along with most other IBM defined macros) clearly document the contents of the registers when control returns to the caller. For ATTACH(X), R14 is used a work register by the system. For LINK(X), if the LINK(X) is successful, when the target program gets invoked, R14 will contain the return address, which will be the address of the SVC 3 instruction in the CVT. If the link fails, and an ERRET routine was coded, on entry to the ERRET, R14 was used as a work register by the system. Since the system uses R14 (most system macros use without saving Registers 14, 15, 0 and 1) if you care about the contents, it is the coder's responsibility to save them before issuing the macro, and restoring them after the macro expansion (and at any error points that the macro could pass control to). === Wayne Driscoll OMEGAMON DB2 L3 Support/Development wdrisco(AT)us.ibm.com === From: Donald Likens dlik...@infosecinc.com To: IBM-MAIN@bama.ua.edu Date: 07/05/2011 08:30 AM Subject: Re: Real return address for link and attach Sent by: IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu This has all been interesting but I don't think my question has been answered (sorry if I missed it).

I never wrote to this forum how to specify MFNetDisk statements and if I wrote one time or two that was a mistake. Maybe mention my product name a lot, is a little improper, but because it is a free product and the number of new users and the feedback I received, make me feel very welcome in this forum so I mention the name without any limitation. Beside this forum and sometime Hercules forum I did not try to publish my product and the true is that I do not know how to do it. Developing advance technical issue make me proud and happy and it makes me feel that I like to share with this forum my pogress with the product and the way I implement it. I know that I am not aware to what is acceptable in forum and what is not. I am spontaneous man. Example is telling about living in Ashdod which this forum is not the right place to write about.

Re: How many CPU seconds can I consume per 10minutes?
Hi Barbara , For normalization method, the one that I learned from Gary King from IBM several years ago and the one that I am using since then, is to use ITR/CP ratio difference between models.Which CPC models are you upgrading from/to and what is your workload type according to your zPCR study?. SU/sec was used many years ago for normalization process and it had much accurate meaning in those days,but with machine architecture changes and especially with using IRD or Hiperdispatch funtions where number of LCPs online and available to system changes from one interval to another, it is been recommended to use ITR/CP ratio differences.( When you check SU/sec value differences between two different CPC models and ITR/CP value ratio of CPC models you will see a difference between two values ratio as well.) Using SU itself is not correct approach also because of the fact that starting with IRD, SU/sec value is not changed even in RMF records itself. In order to use ITR/CP method: From IBM LSPR table you can find out your CPCs ITR value based on your workload type and divide that value to the number of CPs in model. You may do the same process for your older model.These two values will be your ratio that you may use while normalizing your consumed cputimes related to different CPC models. According to what you have explained, I guess,your ITR/CP ratio for new model will be less than your older model.

Background: Traditionally, we have been reporting cpu usage for our box normalized to 100% using the TYPE70PR SMF records. Unfortunately, when the model of the box changes via CoD (or whatever it is called), you cannot even *see* that the capacity has become bigger. Using the total cpu seconds consumed, what you can see is that more cpu seconds were used in the same length interval, either because the number of processors increased or because the processor speed increased. So I have been thinking of doing the 'cpu usage per box' graphic using total cpu consumed in each interval. Which raises the question what is the limit of cpu seconds per interval? Because that is what I need to show management to show how much more we would have needed. We are running on a sub-capacity machine (and our new one will also be sub-capacity, meaning slower processors). So obviously I cannot use 60s*10*no.of.cps to determine the limit, since we will not achieve 600s cpu on one cp per 10minutes for general cps. I think. In addition, I wanted to avoid conversion to MSUs or MIPS (since I am always telling my management that those are meaningless). But for the new machine zPCR was done for our workload by IBM. In the comparison the actual MIPS of several z196 models were downgraded in their number of MIPS (to account for lpar overhead and workload mix, IBM calls it zPCR MIPS).

Re: Z/OS Newbie question
Hilary, Check out CBT file 391, COBANALZ, which can process a whole load library and give you a summary report showing not only compile and link dates but also the language and compiler version used for the compile and other information. It's not perfect (some old compilers didn't put wnough info into the load member), but it's good enough for many purposes. The summary report is in library member order, but you can post-process the report to sort it as you will, or convert the columns to CSV fields and download it to a spreadsheet program, or just download the text of the report and import it into a spreadsheet program as a fixed width file. I don't believe there is any base z/OS facility like the FAQS/ASO feature you described, but you might check with the FAQS company to see if they have a z/OS equivalent.

Re: How many CPU seconds can I consume per 10minutes?
A couple of things: A CPU second is a constant. It has nothing to do with the hardware. It is the approximate number of seconds where a given CPU was observed to be doing work as opposed to being in a wait state. How much work is done -is- a variable that does depend on the hardware. You increase your service delivery by faster CPU's, more of them, reduced workload, or some combination thereof. 'Sub capacity' is a billing/pricing strategy and does not mean slower processors. Indeed, it is often a business justification for faster processors. With the 'sub capacity' strategy comes tools such that management can set some pretty firm limits on software costs. It is not and should not be confused with CoD. You may choose whichever is a best fit for your specific business situation. You can even choose combinations if you run more than one box. For example, 'sub capacity' allows for brief spikes in utilization without penalty. You are right in that the 'capacity' of modern boxes is no longer a constant. Indeed, depending on your strategies, it can and will vary moment to moment. With this variability, 'normalization' is difficult at best. I might propose that a meaningful measurement might be to calculate an average of the ratio of capacity used vs capacity available for each measurement interval. Again, a CPU second may not a good measurement of CPU capacity. IMHO, the best measure of latency is when service level objectives are missed. Perhaps the second best is counting the number of intervals when the box is running full out. You just can't push the utilization to 100% without latency. Interestingly enough, CPU seconds just might be a useful metric for this specific case. That is, if a CPU did not enter a wait state for x clock seconds, then it is safe to assume that there was latency for each of those x clock seconds. Latency would increase exponentially as x increases. Or so queuing theory would suggest.

Re: Real return address for link and attach
On 5 July 2011 09:30, Donald Likens dlik...@infosecinc.com wrote: This has all been interesting but I don't think my question has been answered (sorry if I missed it). It's not so much that it hasn't been answered, but that the premises of your question have been denied. What you said originally was this: I have a situation where my subtask terminates and it seems it returns to somewhere in my program and starts executing my primary task (hard to believe isn't it). I want to check out my theory by determining in a dump where the attachx is going to return to after I execute the BR 14 (and return to attachx). Really this makes no sense, as others have pointed out at some length. Your subtask executes in parallel with your main task, except to the extent that you provide means for ensuring that only one runs at a time - something you have not mentioned doing. The subtask's register contents, other than perhaps R1 at entry, are unrelated to those of the main task. You also said: I would also like to know where LINK(LINKX) is returning to when I execute the BR 14 (and return to link). It has been pointed out to you that the BR 14 does not return to link, but to the operating system. LINK behaves on the surface very much as ATTACH does, except that execution of the program issuing the LINK stops, and does not resume until the LINKed to program returns to the operating system. Some said I could get the real return address in the save area trace but I do not think that is correct since the calling program saves the registers and R14 points to LINK(x) or ATTACH(x) when the calling program is called. I really don't know what you are trying to say, even if I try to parse it assuming there are minor typos of the sort we can all make. At entry to your subtask, R14 contains an OS-provided return address that is quite unrelated to the value in R14 at the time your main task issued the ATTACH. (We know that it normally points to an SVC 3 instruction in the CVT, but that is not a documented interface, though it has been that way since 1964 or so, so let's just stick with the idea that the OS provides the address of some code that will do all the right stuff to end your subtask.) You talk of the real return address, but it's not clear what you mean by this. It is utterly implausible that the OS is providing a wrong address in R14 when your subtask gets control. Either your subtask is returning to the address in R14 or it isn't. If it is, then the subtask will end, and various things will happen depending on some of the options on your ATTACH. If it isn't, because it lost or mangled the address, then it is going somewhere else, and executing some unknown code with unknown results, which could include - if things are really messed up - executing code that should be part of your main task. It was my understanding that attach returned to the OS but in my case I am seeing some pretty wierd things going on if the attached task ends immediately. Perhaps you could be specific about these weird things that are going on, and how your attached task ends immediately. As to the reference to LINK/Attach manuals it simply states that the registers are changed (I had already looked there). It didn't say what it did with the real R14. We're back to your notion of a real R14, and I don't think anyone here understands what you mean by that. I don't know if you are merely having trouble putting your question, or if you have some fundamental misconception about how the machine and the operating system work.

Hi Bruno, It seems useful to me to have a distinct shorthand way to refer to the 2G line vs. the 4G line. Since bar already refers to the 4G line, using mini-bar to refer to the 2G line appeals to me.

Re: Z/OS Maintenance
I left Brian's text intact because it contains advice worth seeing again. Some additional points. Besides RSU there are other good mechanisms as well: --- ASAP and AST tracking with email notification in IBM ServiceLink. I feed my current FMID inventory into ASAP--I wish that were easier to accomplish--and then track those APARs that look pertinent. I don't generally bother tracking PE or HIPER fixes because those will show up in a 'critical fix' order. The ATTENTION fixes may not show up, however, so I track them in AST. --- Periodic ERROR SYSMOD reports (already mentioned). --- FIXCAT reports. Fix Category is a relatively new mechanism similar to PSP buckets but way easier to use. A FIXCAT report will show a wide variety of available fixes that various component groups have identified as very important to install. Caution: in order to get FIXCAT HOLD records, you must request the entire inventory of enhanced hold data each time you pull it. In other words, FTP 'get full.txt' from service.boulder.ibm.com . There's that old saw about not fixing something that ain't broke. My response is that it's *always* broke. You may or may not personally encounter the problem, but every corrective APAR tells a tale of woe for some poor soul somewhere. Software installation these days comes pretty close to a science, but software maintenance is still an art. You have to balance conflicting interests and goals and adopt a practice that works for you in your shop. At the end of the day, if a big problem befalls you, and you have to tell the story to your boss, would you rather have to explain why you... 1. installed a HIPER PTF that went south, or 2. refrained from installing a HIPER PTF because (insert tailored excuse here) I like #1 because it shifts blame to the fix provider. It's also less taxing on the imagination than #2. . .

The important part is to actually do the maintenance and not get (too) far behind. There are a lot of sites that tend to get several releases (years) behind and then they end up calling me (or someone else) to get them back up to date. The important thing is that you do some sort of maintenance on some sort of schedule. The IBM REDBOOK pointed to previously in this thread is actually very good about giving hints on how you should perform the maintenance aspect of our Systems Programming jobs. Maintenance used to take a REALLY long time, and now it's actually fairly simple. There are a lot of factors to consider and the more complex your site, the higher the difficulty level in keeping relatively current. You really have to plan your system for the method you choose. There are those that feel that they can apply maint on a fixed schedule, and if that works for them then that is fine. There are others that believe that you should install a new release once a year (or two) and only put on maintenance that you absolutely need in order to fix a problem that you are experiencing. That's fine as well. What ever you decide, it will be great for you and your site. Personally, I like the method of installing a new release periodically and applying the current maintenance (as needed), and then doing all (or most) of the hyper fixes in between. It's a little more work, but it tends to work out good for me. I don't have a fixed schedule, but I try to keep the sites that I maintain at about the same level. There are quite a few. My reasons are because if I run into a problem at one site, I can be proactive and fix it for the others as well. It's terrible to admit, but this way I look really good because the ones that reported the problem are happy that I fixed it for them, and the others are totally thrilled that I was looking out for them. It's sort of a win-win thing, but I have to admit that it is a little more work on my end to keep everyone relatively equal. Also, by equal, I don't necessarily meant hat they are even at the same release, I maintain sites from 1.4 (unfortunately, and until recently I still had several OS/390 sites) ) to 1.12, but (where I can) they are all at the same level of maintenance. Most fixes are applied back to the older releases (as long as they are supported) so it's not as hard or as complex as it might seem. I try to keep them all as current as possible, but not all of them want (or need) to be on z/OS 1.12 so I try to be as flexible as possible, while keeping them all current (as much

I'm delighted that unassigned bits are required to be zero, else a specification exception is recognized, and it won't dispatch to an instruction address inconsistent with the AMODE.

It must be 0 for LPSWE and 1 for LPSW, but in either case a 0 is loaded into the PSW.

Other OSes routinely permit use of storage within that range, and routinely support execution above 2GiB and above 4 GiB. The need for the bar has a number of reasons. One of the major ones is that in 32Bit Addressing the high bit of the 32bit addresses was used as a flag to signal end-of-parm-list. Thus the maximum address that could be passed was 2GiB-1. While a non-zero high word in the 64Bit addresses says that an address was over 4GiB, a zero high word with the high bit on in the low word could be mean with an address between 2GiB and 4 GiB-1 OR a flagged address under 2GiB so that 2GiB range is banned for addresses so that only the flag meaning is valid. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
