Re: How to eliminate the igd17223i message from the syslog under sdsf.
This doesn't help on the SYSLOG panel, unfortunately, but on the OPERLOG panel, you can use SDSF's filter functionality. From the LOG panel, select FILTER. Choose option 1, FILTER. Then, in the columns, set COLUMN equal to MSGID, OPER to NE, and VALUE to igd17223. If you want to emulate syslog functionality on the operlog panel, you can also use the filter functionality to limit the messages to a single system. --- Kevin McKenzie External Phone: 845-435-8282, Tie-line: 8-295-8282 z/OS BCP SVT, Dept FXKA, Bldg 706/2D38 From: Klein, Kenneth kenneth.kl...@kyfb.com To: IBM-MAIN@bama.ua.edu Date: 08/05/2009 11:55 AM Subject: Re: How to eliminate the igd17223i message from the syslog under sdsf.

Re: Enforcing CPU Time
Just as a note, on V1R9, and rolled back to V1R7 and V1R8, there is now Blocked Workload/trickle support, which, if configured, will make sure all work, even discretionary, gets some access to the CPU. You can configure how much of the CPU you want to give discretionary work, assuming your CPU is 100% utilized. This might forestall screams. And if you're willing to enable WLM-managed initiators, this can ameliorate the problem of a job tying up an initiator, since WLM will start more if it decides there is capacity available.

A cap is better than cancelling. I'd rather have a test job hang than blow it away and come back and use more resources later. That's what 'Discretionary' is for. Ted: I am mixed on your answer. The problem as I see it if you cap it it ties up the initiator for a potentially long time. It also could mean that you do not meet service levels and your management gets dinged (and the politics that follows). Yet if youcancel the job (322 or 222 or whatever) you can free up the initiator for other test jobs to execute. Now days the operator does NOT sit around and monitor jobs so there is no easy way for him/her to know that the job is essentially sitting there.

On the overall scheme of things people can live with 322 or 122 or whatever a lot easier than no job thruput.

The answer is NOT to fire off another initiator as we had it finely tuned and (IIRC) only one job could be running against IDMS at the time. Hey I didn't design it we just implemented what the IDMS person wanted. There were also other issues of resource availability (tape drives and the like). This was a real world situation. We even went to the programmers management and explained the situation and the agreed that a 322 or 522 or what ever was acceptable rather than delaying other people.

Supposedly yes. But I didn't see anything on Amazon's site about that feature. I read in a blog that Amazon can, at its discretion, enable and disable features via the wireless. That's why I have wireless turned off most of the time. Well, that also increases battery life as well. So, if such is possible, there it is likely pushed whenever Amazon wants to. I don't much like that either, but I don't know for sure that they actually have that ability. Assuming the Kindle DX functions similarly to the Kindle, which I have, yes, Amazon can push updates down over wireless.

Re: PDSE Anomaly?
Read/write sharing of PDSEs between z/OS images not in the same sysplex is incredibly dangerous, and very much not supported. What happens when you do share read/write between PDSEs is undefined; if you're lucky, you can recover, if you aren't, you have to restore the dataset from backup. Read-only sharing between images works, but is also not supported. I don't think IBM has done enough to get this message out, because questions like this seem to pop up on a regular basis, but, very simply, do not make updates of any sort to a PDSE that is being shared beyond the boundaries of a sysplex. SMS and other things cache data about the structure and contents of PDSEs, and they trust that the cached data matches reality, and if you make an update from outside the sysplex, the cached data does not match the contents of the PDSE, and at the least weird, and at the worst bad, things are pretty much guaranteed to happen. If possible, I'd suggest restoring your DB2PROD.SDSNLOAD from backup, and if you're going to make changes to it, only do so when all the images accessing it outside the bounds of the sysplex of the image making the update are down. If that's not possible, you need to create multiple instances of DB2PROD.SDSNLOAD, one for each sysplex accessing it. --- Kevin McKenzie External Phone: 845-435-8282, Tie-line: 8-295-8282 z/OS BCP SVT, Dept FXKA, Bldg 706/2D38 From: Longnecker, Dennis dennis.longnec...@courts.wa.gov To: IBM-MAIN@bama.ua.edu Date: 05/19/2009 07:01 PM Subject: Re: PDSE Anomaly?

Even with a consistent single cap value, one would normally expect the online activity to hit this cap at sometime in the month, so even a looping batch application on one night would likely not impact monthly billing. What an unusually hot batch night could do in the worst case, if running with a single cap value, is cause you to start the daily online load with the LPAR already in a capped state restricted to the cap MSUs, instead of being able to use the total machine MSUs for several hours until the 4-hr average reaches the limit. This is the beauty of capping from the user's point of view - it constrains your software cost to the MSU cap, yet allows your instantaneous critical load to exceed the cap MSUs up to max MSU capacity of the box even for an extended time of several hours until the 4-hr average reaches the cap; and even allows the 4-hr average to exceed the cap as long as the delivered MSUs is restricted to the cap MSUs while capping is in effect. WLM manages current workload. It is not designed to restrict batch resources at a time when the system is not constrained just because that usage might have a negative impact by forcing earlier than usual capping several hours in the future. What the user wants to do is put a lower cap on batch, so that if it goes berserk and caps out the processor, that at least when online starts he can raise the cap and hopefully get the system far enough from a capped state that the online applications may have a few hours of unconstrained usage. My understanding is that IBM will grant an exception if the high 4-hr average interval for billing is the result of some exceptional looping program; but in the case described it is more likely that removing any problem batch periods would not reduce the monthly max under the cap. The interaction of the batch problems with capping would have just effectively stolen resources that could have been used more effectively by online applications several hours later in the day. Following such an incident, the only way to relieve any subsequent CPU-constrained, online performance problem would be to raise the cap above the normal value, and I would be surprised if IBM would grant an exception to the rule that the max cap specified during the month is the one that determines the upper bound on billing. Being a relatively recent user of capping ourselves, I would like to think that our monitoring of our system would catch such batch problems before they could contribute to later capping issues, and I also dislike the idea have trying to micromanage a system in this way; but I have also given some thought to the implications of dynamically changing the cap and can understand what prompts the query.

Re: MaxSpace and Real Memory
Yes, with only 8GB real, setting MAXSPACE to 8GB could cause problems, or a system outage. This is not an IBM recommendation, but in Poughkeepsie System Test, we've settled on 50% of real for small images (6 GB or less), 40% for 6 - 10 GB, and 30% for images greater than 10 GB. I'm not sure offhand if there's a way to determine how much space you need. You could alternate between taking dumps and raising the MAXSPACE until you get a full dump, or you hit some limit. Again, this is not an IBM recommendation, but I'd be reluctant to go above 6GB at most for MAXSPACE. I wouldn't leave it so large after you have the dump. We have taken systems down in the past by having MAXSPACE set too high. --- Kevin McKenzie External Phone: 845-435-8282, Tie-line: 8-295-8282 z/OS BCP SVT, Dept FXKA, Bldg 706/2D38 Lizette Koehler stars...@mindspring.com Sent by: IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu 04/07/2009 03:10 PM Please respond to IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu To IBM-MAIN@bama.ua.edu cc Subject MaxSpace and Real Memory I am currently working with our DB2 group on a problem that requires an SVC dump.

Re: Soft capping advice sought
I apologize, since I may be wrong here, which would be somewhat embarrassing given that I work for IBM, but I don't think that's entirely right. Assuming all the LPARs are on the same CEC, in such a circumstance, the number of MSUs guaranteed to any LPAR is going to depend on the weights of that LPAR versus the weights of all the other LPARs on the CEC, if they're all busy at the same time. The set of LPARs will be capped at 100 MSUs, and LPAR B will be capped at 10 MSUs, but you're not going to guarantee all capacity available to LPAR A whenever it wants it. If, in addition to these recommendations, you gave LPAR A a weight of 999 and all the other LPARs a weight of 1, you'd be guaranteeing A could always have basically all the MSUs available to the LPAR group. I'm not sure how to make LPAR B the second favored LPAR, though; if you were to give it a weight of 100, say, with LPAR A having a weight of 999, you'd be giving LPAR B an entitlement 9% of the CEC, if it wanted it. Now, if all of these LPARs were in the same sysplex, I think you could do what you wanted to do with a fairly stringent WLM setup and LPAR weight management. If the LPARs are on separate CECs, I have no idea how to do what you want to do. --- Kevin McKenzie External Phone: 845-435-8282, Tie-line: 8-295-8282 z/OS BCP SVT, Dept FXKA, Bldg 706/2D38 Al Sherkow a...@sherkow.com Sent by: IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu 04/02/2009 03:31 PM Please respond to IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu To IBM-MAIN@bama.ua.edu cc Subject Re: Soft capping advice sought Put them all in one group, set the group cap to 100 Set LPAR A's defined capacity to 100, and give A the most weight in these 5 LPARs.

Re: zIIP queue vs CP dispatch when zIIP is fully utilized
As someone else said, it depends. By default, if you have a zIIP configured and online, non-zIIP processors will do zIIP work if the zIIP processor asks for help, which it will do when it thinks it is necessary (which happens before it is 100% utilized). Work will then be processed by normal CPs based on dispatching priority of all work units, zIIP and non-zIIP, as determined by WLM. However, if you set the IEAOPTxx IIPHONORPRIORITY to NO, and have zIIPs online to your LPAR, zIIP work will not run on normal processors unless there's a unit of zIIP work holding a resource that a non-zIIP unit of work needs access to. In general, IBM recommends you accept the default IIPHONORPRIORITY setting, and allow zIIP work to run on normal CPs. Did you use PROJECTCPU to determine how much work you could offload to zIIP?

Also consider the Capacity Planning part. When you add Specialty processors to the mix with CPs in an LPAR, that LPAR will now have an increased n-way MP effect. Example, if you have a 4-way LPAR and add 1 zIIP and 1 zAAP, that LPAR now behaves almost like a 6-way. And only the CPs can run general work. Remember- Specialty Processors are not for Performance reasons or increasing capacity. They are for keeping your license costs from going up when you need to add more processors. According our understanding not only , you could free up the general CP's if you could dispatch something to zIIP I just di a presentation on this at CAWorld, and will repeat it at Share in Austin. There will be a webcast for CA customers in mid-January. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Scott Barry Sent: Thursday, December 04, 2008 SYSN 02:56 PM To: IBM-MAIN@bama.ua.edu Subject: Re: zIIP queue vs CP dispatch when zIIP is fully utilized On Thu, 4 Dec 2008 14:15:04 -0800, Mursel Tasgin [EMAIL PROTECTED] wrote: Hi, Planning to use zIIP processor and try to figure out what performance issues we may experience.

Re: Add Storage To Lpar - z/800
Did you define any storage as reserved in the activation profile? If so, yes, you can. If not, I don't know of any way. Note that it's not just a re-IPL you would need to do; you would need to redefine the activation profile with more storage and then reactivate the LPAR.

We have 4 Lpars defined, only two of them running now. Both Lpars have 3G of memory. I think the 2 Lpars that aren't running have .5G each. I know we have a little less than 1G that is free and unassigned, so I'm wondering if I can add that to our production DB2 lpar without having to IPL? We just installed DB2 V8 in compatiblity mode. Response time went from .5 seconds average to 1.2 seconds. No one has been complaining, but this is a week that many people have taken off, so volume is down. We have to get a handle on this by the end of tomorrow, as we are closed Thursday and Friday. We have a DB2 guy who is going to ask on the DB2 list about the DB2 portion of this question, but if anyone here has anything to contribute, I would appreciate it. We primarily run some Peoplesoft applications on this Lpar. We are running at 100% CPU busy on the DB2 lpar most of the time this week, whereas before the install of DB2 1.8 in compatibility mode, most of the time the CPU was not at 100%. Thanks in advance.

Re: What's current CPU utilization at ANOTHER system?
It's indirect, but in the DA panel, look at the SCPU% column of an address space running on System-B. Similarly you can get zAAP CPU utilization from the szAAPcolumn, and zIIP utilization from the szIIP column. Note that the systems don't need to be in the same MAS for this; it's RMF that provides this data, not JES.

Re: PDSE Help!
You could try this (haven't tested it, but I think it should work, assuming you haven't made any changes to the PDSE on the plex that has it in linklist): remove PDSE from LLA and linklist. On the system you made the change from, copy the contents of the PDSE into a new PDSE, accessible from both systems. Add the new PDSE to LLA and linklist on the original plex. If you've made changes from both plexes, I don't think there's any good way to recover.

Re: PDSE Help!
The proper way of handling a PDSE anywhere is after interacting with it on a given plex, not to make changes to it from another plex. You can share PDSE's read-only, but never read-write. We've been burned by that on many occasions within System Test.

Re: Cleanup a unconnected Coupling Facility
There are probably outstanding failed persistent connections to the CF that you need to delete. Use the command d xcf,cf,cfname=CF2 to get a list of structures that XCF thinks is allocated on that CF. Then you can use the command d xcf,str,strname=strname to get a list of connections to that structure. There will probably be some that are marked failed persistent. These are what are preventing the change. Optionally, depending on what release of z/OS you're running, you can issue the command d xcf,str,status=polchg assuming you've tried activating a new policy that doesn't contain the CF. You can use the command setxcf force,connection,strname=strname,conname=connectionname Obviously, be very careful you're forcing the correct connections. Once all the structures have been deallocated to the CF from an XCF point of view, you should be able to remove that CF via a CFRM policy update. That should work; we have to go through that process on the test floor once or twice a month.

Can I think this way, it is enough that just a *TSO* as you snapped, then WLM will know TSO users's transactions...? When new work is submitted to the system, it has to go through WLM to be classified. One of the characteristics that new work is judged on is the subsystem name the work is coming from. In the case of TSO, the subsystem is TSO. So if you have an entry for TSO, and no rules in there, things from the TSO subsystem will be classified to the default service class for TSO. In the case where there's no subsystem defined, it will be classified to SYSOTHER, which is essentially discretionary.

Re: How to find uncatalog datasets.
I would like to know information how to list the uncatalog datasets. I would like to know whether we can use IDCAMS utility or any other utility. Thanks. I've written REXX execs in the past to do this. Give it a list of volumes, use TSO utilities to get a list of datasets on the pack, and then do an IDCAMS lookup of each dataset name. If the dataset is not found, or is found on a different pack, it is uncataloged, and can potentially be deleted. Depending on how your catalogs, systems, and DASD are connected, you have to be really careful about this sort of job.

Re: Delete DS Held by LLA and XCFAS
I can't comment specifically on what CSF.SCSFMOD0 is being used for, and what security implications there are; other people have done that. But in order to free it up from LLA/XCFAS, you need to issue the console command 'F LLA,REFRESH'; you may also need to issue the console command 'SETPROG LNKLIST,UPDATE,JOB=(*)'. The first command will tell LLA to update what it's caching based on the current linklist; the second command tells address spaces that are currently running to update their linklist based on the current active linklist. Note, however, that the second command can be *dangerous*, if the linklist gets updated at the same time as the address space is searching for a loadlib; you can get various sorts of ABENDs. A much safer way to do things would be to rename CSF.SCSFMOD0 to, say, CSF.SCSFMOD0.OLD, refresh LLA, and then allocate the new dataset, if that's what you're trying to do here. Delete CSF.SCSFMOD0.OLD after you've IPLed all the systems that might have it allocated.
