Re: Duplicate CP Monitor records TCPIP
I guess some more testing is required. At least i'm not the only one to be supprised. Indeed, a pmr sounds about right at this point. I guess a test would be pretty easy, restart (logoff/logon) one of the TCPIP stacks and see if it produces one record. Next fiddle with NETSTAT OBEY and see if the second record appears. Your remark on DIAG 0xDC does point in this direction. I also discussed with a collegue and he confirmed the NETSTAT OBEY at least once after the last IPL. Thank you all for the help. Regards, Berry.

Duplicate CP Monitor records TCPIP
Hi listers, I am looking at processing the userrecords in the CP MONITOR for the TCPI P stacks. These are in CP MONITOR domain 0A record 02. The data is collecte d though a STARMON stage, basically PIPE STARMON | locate selection | fielid. Most LPARs have records like I'd expect them but I have found that in one LPAR we have duplicate records for subrecordtype 05 for each of the the O SA devices. The CTC's for VSE systems have one record per minute for each VSE system. The OSA links have 2 identical records (apart from a slight difference in timestamp, a few miliseconds apart). A second IP stack even writes 3 reco rds for every minute. So basically we see: 00:01 VSE1 00:01 VSE2 00:01 OSA1 00:01 OSA2 00:01 OSA1 00:01 OSA2 00:02 ... What can cause the CP monitor to have these duplicate records? TIA, Berry.
Re: Duplicate CP Monitor records TCPIP
Hi Scott, Yes, the records are identical. After a SORT UNIQUE the duplicate records are discarded. The only thing that is not identical is the TOD field. The second (and third) record are produced a few miliseconds after the first. When I discard the miliseconds the records themselves are truly identical. That leads me to believe that these are seperatly created records. The record produced by the TCPIP stack contains data from the OSA device, we are interested in the number of bytes in and out for the device during the minute interval. As I understand it there is a buffer for each device. So the OSA devices each have a record and the CTC devices also have a record. And indeed that is what we get on other LPARs. Only on this particular LPAR we have more than one record. And only for the OSA's, not for the CTC's. Regards, Berry.

Re: Duplicate CP Monitor records TCPIP
Hi Scott, Yes they are the same, same VM levels, same basic setup for all VM's and IP stacks. In one case, our local IP stack, even uses the same osa device. In one LPAR it produces just one record per minute, in the second LPAR it produces three records. And only one virtual CPU. But for these records CPU is not an issue. Regards, Berry.

(though I would think it would show as a different OSA shrug) - Could a different ports be being used on the same OSA? You've likely thought of this stuff already - just thinking of stuff I would check. Can't think of any reason offhand. Well - maybe one: does TCPIP on this LPAR have 2 virtual CPU's defined?

Re: Duplicate CP Monitor records TCPIP
Multiple links? You mean on the OSA or within the IP stack? Yes, multiple links on an OSA. In LPAR1 we have one IP stack (EE00-EE02) and a VSWITCH (EE04-EE06) on the OSA. In LPAR2 we have two IP stacks on the same OSA (EE00--EE06). The customer stack also has a backup on a second OSA (EF00-EF02). Within the IP stack there is one link defined for a device.

Re: z/VM shutdown
Hi Tom, I have seen it happen, both planned and unplanned. IIRC I did post a question on this here or in the linux-390 list, some years ago. We have shutdown guests through a signal, and sometime still do. And we have had an unplanned outage because someone at our HMC stopped the LPAR (don't know in detail what they've done). After starting the LPAR again we noticed a SIGNAL had forced VM down. SFS was shutdown through a signal, all others obviously were forced during VM shutdown. O, this was back at zVM 4.4 so it's there for some while now. We have tried to setup a good solution for shutting down VM and it's 2nd level systems (linux, VM, VSE) but there are some risks. You should ensure the guest will indeed correctly shutdown within the set time. Either have a good automatic shutdown procedure triggered by the signal or set the timeout to a high number. At VM you should trap the signal to run a shutdown procedure for services that do not trap a signal, on VSE you have to trap the signal and script a shutdown, a linux guest traps the signal as an CTRL-ALT-DEL. Regards, Berry.

Re: DIRMAINT
You need to issue DIRM NEEDPASS NO again. I guess the file is without the DVHOPT statement. They get rebuild during rebuilding of the directory. Part of this is the needpass no option that gets changed. (I guess the CRC is different.)

Re: Capacity Monitoring question
Hi Nick, We monitor VM on page usage and page IO, our guest on VM for Queue and storage usage (main, xstor and swap). Also we monitor guest CPU usage and metrics like the limit list. Linux memory is always at 100% so no sense in monitoring over there but we do monitor swap usage. Linux CPU gives bad numbers to start with (yes even on current kernel levels they are still wrong) so don't monitor CPU on the guests. Actually, 100% CPU is not a bad thing at all. Where most OS-ses become less responsive above 90% z/VM will still give you good response even at high numbers. We like to have it above 90%. Obviously you would need some capacity for new guests. So when you are running 100% CPU all the time there can be a case for an additional IFL. But also look at the guests, determine if they are running processes you don't need or that hurt overal performance. Watch your linux guests on responsetimes and batch runtimes. Set a good relative share and if that doesn't help you could consider adding IFL's. Keep VM paging below 50%, add paging DASD when needed. We have a VM that is overcommitted to 9:1. Our production Linux VM is at 2:1 with room to spare. Expect even high page IO rates, 1000's IO/sec don't have to be bad. Keep an eye on guests that are competing for storage. Especially loading users and E-lists can point to a resource problem. Try to fix it on the guest first (eliminate processes, reduce memory sizes etc). Make sure the guests don't stay in Q3. It will hurt other servers. So eliminate unused processes, don't use pings or other keep alive tooling. Be aware that most regular linux tooling keeps the guest active. Obviously when you are running batch the guest will stay in Q3 but then it's in there for a reason. Some of these issues are also covered in the linux-390 list (http://www2.marist.edu/htbin/wlvindex?LINUX-390). Take a look over there also. Regards, Berry.

Performance on the linux guests is acceptable at this time. Aside from waiting for the linux users to start complaining - what metrics and thresholds should I be tracking as early predictors of capacity problems? Obviously if CPU usage is constantly 100% that's probably not good. I'm currently watching CPU, IOWait and Stolen time but wonder if those are sufficient. Any suggestion as what a good maximum number is? Memory is a larger concern - In a previous life as a mvs sysprog I would watch paging/swapping and delay times among others. Are there any rules of thumb regarding paging or swapping in z/VM? Is there something better that paging/swapping for capacity prediction?

Re: Need advice on moving a Linux guest from one z/VM LPAR to another
We do this quite often. We have 4 VM's and guests can be moved freely to any of these LPARs. It depends if you need other DASD as well. If you can share DASD then make sure the DASD is available on both VM's. Shutdown (logoff) the guest in one LPAR and start it in the other LPAR. The directory entries in both VM's must be the same, except for the password (the guests have only one VM where they can logon, all others have NOLOG). That is how we move guests between LPARs. If you want to move to other DASD as well you need to copy the DASD using DDR. The easiest would be to create an identical guest entry with the new extents, such as guest1 and guest2, where guest1 is the guest to be moved and guest2 is the guest on different DASD extents. Next 'clone' the guest to the new DASD extents. Then start the new guest in your other LPAR. The cloning process is described in several redbooks, but it is basically a DDR of all minidisks.

Re: z/VM Monitor Records
Hi Billy, First you can look at MONWRITE within VM itself. It writes all records to disk. Process it wth MONVIEW (on the VM download pages). We have an own process. Main reason is we want to enable all MONITOR in VM so we can monitor all parameters online. But we only want to write selected records to disk, just the ones we need. Also a 3390-3 is to small to store all within one day. It is based on the MONITOR processes descibed in redbook REDP3818 (http://www.redbooks.ibm.com/abstracts/redp3818.html?Open). The process has the STARMON stage in a pipeline. It retrieves the records and writes selected records to disk. As Jeff said, search for STARMON, it will show up. A similar process is in use for monitoring and ticketing. Just to start, take a look at this thread in the linux-390 list: http://www.mail-archive.com/linux-390@vm.marist.edu/msg58022.html Regards, Berry.

But linux load differs from the way CMS and VSE loads run. To what extent is this applicable for VSE and/or CMS loads?

With that said, we’ve asked ourselves is ABSOLUTE 20% enough? The manual says once you have defined the minimum target ABSOLUTE SHARE to total 100%, the scheduler reserves 1% for the RELATIVE SHARE users. It goes on to say that once an ABSOLUTE SHARE user has reached its minimum target share it only gets more if system resources are available.

I suspect it's trying to keep heavy CPU users from hogging the processors. To get back to the original question, Jim, I think you need to describe what the z/VSE guests are doing. If they're supporting interactive users (e.g., CICS), you'd want one answer from the assembled masses. If they're true batch workloads, the answer should be quite different. Since your system's perceived responsiveness likely depends on how quickly TCPIP (and VTAM) gets serviced, a high share is called for. In your situation, is the same true for RSCS?

Re: Time out an SFS command
Would PIPSTOP cancel the SFS command (or any CP/CMS command for that matter)? If so then you could use PIPSTOP to end the pipeline. Just a theory, not tested in any way... 'PIPE (end \) command LISTDIR ...', /* execute command */ '| stem',/* store */ '\ literal +60', /* 60 seconds */ '| delay', /* wait for it */ '| pipstop' /* cancel command */ Regards, Berry.

Anyway, the best approach for the rest of us to this problem would be to use 2 userids, as was already suggested. I doubt it would have any affect on SFS. If this happened to my own id, I just enter #CP IPL CMS to cancel the APPC wait and recover and there was never a problem in SFS after the communication was fixed or reset.

MPROUTE close console
Hi listers, Is there a way to close the console for MPROUTE? We use NETSTAT CP CLOSE CONS for TCPIP, SMSG FTPSERVE CLOSECON for FTPSERVE but I can't find a wa y to do the same for the MPROUTE user. I also tried a CP SEND MPROUTE CP CLOSE CONS. It didn't give me an erro r but still the console is not closed. TIA, Berry.
Re: MPROUTE close console
OK, so that was my mistake. Thanks. CP SEND CP... does indeed give me the close I was looking for. Since I am on zVM 5.4 I could also use the FOR command.

OSA port1 affects port0
Hi Listers, We have two VM's on one z10. Both VM's have identical configurations. - vswitch1, connected to port0 on OSA EB (primary) and EC (backup) - vswitch2, connected to port1 on OSA EB (primary) and EC (backup) - vswitch3, connected to port1 on OSA EB (backup) and EB (primary) Some months ago we noticed that almost no traffic was running on vswitch1 . Several database connections timed out and sshterminals had very poor res ponse. As it turned out a large load on vswitch2 (backup of a 20G file) prevente d OSA port0 to run it's normal load. It looks like that port1 has priority over port0. When connecting to the second LPAR, there is no problem. So it looks like a problem with running load in one LPAR (VM) on the two ports on the one OS A at the same time. At this moment we have moved vswitch2 and vswitch3 to OSA EC and vswitch1 is still connected to EB. But in the current setup we don't have the regular failover we used to have. What can we do, other than buy some additional OSA's? (Yes, there is a PM R for both IBM software and IBM hardware but that's taking quite some time now.) TIA, Berry.

Re: Suppressing messages
AH, OK, I understand. We run a monwrite that gets never stopped. Within MONWRITE we run a custom pipeline, it retrieves data with the STARMON stage and a second stage waits for the cleanup command with STARMSG. The cleanup command forces the monwrite machine to cleanup the disks. Before that we ran the basic MONWRITE and then we stopped the monitor every day. But we also have PERFKIT running so there was always at least one user connected to MONITOR. So that's a way for this, just add a user that connects to the MONITOR and does nothing with the data (PIPE STARMON | HOLE).

Re: 'Approved' Change Techniques - Where Documented?
Hi Jeff, As for the 'official' documentation, i'd suggest the service guide. When applying service updating the CF1 or 190 (490) is one of the steps. But perhaps that's overkill for trivial changes. IMHO, the best thing is to write some workinstructions for these kind of changes. If required one can still point at the manuals, such as the service guide, within this instruction. Also it depends on how your system has been configured. As long as you use the IBM deleved installer system then you can use the sevrice guide as reference. If your system has been tailored to your needs then it might be the service guide doesn't provide the correct instructions. As for our systems, these are not quite build the way IBM would expect so the service guide, with its instructions, is only applicable on our installation system. We have created our own instructions for updating files on the production systems. Regards, Berry.

Re: z/VM 5.4 or 6.1 on new z10
Hi Mike, We run 5.4 on z10. And since we also have some VM's on z890 we have decided that 6.1 didn't give us the advantage we would need to justify maintaining two VM levels. As for your case, you can't run 6.1 on your current machine so look at it the other way. Can 5.2 run on z10? Or perhaps, would you require service (latest RSU) to be applied before you move to the z10? In that case you require some work on the current system as it is now. I'd say move your 5.4 into production, including the lastest RSU, before you move to z10. That would make the move easier because you then only have to move to the other CPU instead of all kinds of migration activities on to of the move. And it would make your current system supported again. You can decide on zVM 6.x after you are on the z10. Regards, Berry.

Re: pipe question?
We run such a process but not within one pipeline. The rexx exec runs in a PROP user that monitors the linux guests. I do like PIPE so there are some pipelines inside the exec. 1. When our CMS scheduler sends command KICK_LINUX the exec will build a list of commands. Basically your step 1. 2. When a Linuxguest issues KICK_LINUX the command for that user is removed from the list. Basically your step 3. 3. Everytime KICK_LINUX is called the first line of the list is send to the linuxuser in that line. This way the exec doesn't have to wait for a script to end. And during that time PROP has control so any message, either related to KICK_LINUX or not, will still be processed by PROP. The only problem is that we can't tell if the sequence has stalled. If guest3 doesn't return the KICK_LINUX message guest4 will never be triggered. I guess your step 4 will tell you if it has stalled (or rather when it doesn't tell you...). Since we run automatically I would prefer the other way: 'Your sequence has stalled. Please call System support.' but I haven't figured out how to detect a stall. Regards, Berry.

Re: Justifications to migrate to z/VM 6.1
Hi Jose, We have a few LPAR's running on z990 so even if we could justify we can't move those to zVM 6. That would leave us with two installation systems and we prefer to have only one. We do see some improvements but not enough to justify the two installation/test systems. So we remain on zVM 5.4 for now. And since the EOS is now in 2013 we have no need to migrate quickly. We usually plan to install either a new version or an RSU once a year. Both will give us the same effort so for us it doesn't matter what option we use. At the end of this year we will install the latest RSU instead of the most recent zVM version. We would like to be on the most recent version if possible but since we have z990 we have a compelling reason *not* to move to zVM 6.1. If we had no systems on z990 I guess we would migrate to zVM 6.1 at the end of this year. Perhaps zVM 6.2 would give us the justification... Regards, Berry.

REXX variables
Hello listers, We have a rexx exec called by PROP when an event occurs. But it didn't gi ve us the result we were expecting. I have changed the exec now, hopefully i t will be good. But still, why didn't the exec work the way I expected? I h ave tried to replicate the result but was not able to. Exec PR_VSRVD looks like: Address Command 'PIPE (end \) stack | stem data.' If data.00 Then Do cmdtrap = strip(data.1) parse var cmdtrap w1 w2 w3 w4 w5 w6 w7 w8 w9 w10 w11 . If w1 = 'DMSFRO159E' w2 = 'INSUFFICIENT' w10 = 'FROM' Then DO do some stuff here End End Now I would expect the IF statement to trigger if w1, w2 and w10 are li ke above. But looking at the trace: *-* IF W1 = 'DMSFRO159E' W2 = 'INSUFFICIENT' W10 = ' FROM' DMSFRO159E DMSFRO159E 1 INSUFFICIENT INSUFFICIENT 0 0 FROM FROM 0 0 When testing the same thing manually all compares are 1 and the do-end is triggered. What could be the cause of this? Could PROP or something else in OPERATOR cause the exec to behave differently? Note, this is on VM 2.2, CMS level 13. (And before anyone notices, Yes I know, there is no point in comparing w2 and w10 since w1 is actually that message so the new exec only triggers on w1.) TIA, Berry.
Re: REXX variables
Looking closer at the trace, all records appear to be in upper case, even the records that are in lower case. Does (or perhaps i should say did?) OPERATOR in VM 2.2 translate everythi ng to upper case? In zVM 5.4 we also see lowercase in the OPERATOR log. Regards, Berry.
Re: Copying spool without SPXTAPE
Terry, We build our VM's in an installation system. The DCSS entries are saved on minidisk with DCSSBKUP, including the DEFSEG definitions. During GCS building we receive the file onto a minidisk before we IPL the RDR to build GCS. Next the minidisk containing the DCSS and GCS images is transferred to the target VM image, just like other CMS minidisks. In our case usually with PIPEDDR. On the target, we restore with DCSSRSAV. The GCS IPL is punched to the MAINT RDR and then IPLed to resave GCS. CMS is build with an IPL 190 SAVESYS. Regards, Berry. Op 27-05-10 21:04, Martin, Terry R.

Re: Migration questions
After install we rename a DASD volume as soon as possible to fit our names. Next we build our production VM's based on the install system. The RES and SPOOL get a new volume name. So for instance VML1R0 (VM-linux 1, res pack 0) becomes VML1R1 (... res pack 1) and the same for SPOOL (VML1S0 becomes VML1S1). Our page volumes are reused in every VM so they never change names. Note that our RES contains software and essential minidisks only so it can fit within one 3390-3. If it doesn't need to be on RES it has been moved off to other volumes. If we don't need it in production (VMSES for instance) we don't copy it to production dasd in the first place. Regards, Berry. Op 10-05-10 19:23, Karl Kingston schreef: We're running z/VM 5.3.

Copy files changed by RSU
Hello listers, We are upgrading the zVM 5.4 to RSU 0903. I am looking at enrolling this upgrade from the install system to our production VM's. Our install VM contains the full VMSES environment, our production VM's only contain the productsdisks that are required for running VM. For instance, only MAINT 193 is available in production, the MAINT 493 is only in the install VM. Basically we would like to transfer only those files that have been chang ed by the RSU and/or PTF's. I compare the LISTFILE (ISO for all minidisks fr om the old and new install VM to find files that have been changed. Either a change in date/time, records or blocksize will be noticed, as well as new files. Next I only select the minidisks that are in the production VM's a nd the files on that minidisks that have been changed. Obviously, some disks can't be tranferred this way, the MAINT 190 is transferred using DDR so that we transfer the entire disk instead of only the S-disk. Now I do see files that have been changed but do not have the filedate se t to the date of applying the RSU. That makes me wonder, could there be a f ile that is changed but is not found this way? For instance, a file where a b yte has been changed but that is not reflected in a change in filesizes or timestamp? Also, would copying files have impact on other functions? When the 190 or 19E is changed CMS has to be rebuild. Could the same be true for segments such as HELPSEG or CMSFILES (to name a few)? Segments are copied/transfer red using the DCSSBKUP but are these still valid when individual CMS members are copied too? TIA, Berry.
Re: Copy files changed by RSU
Hello Franz Josef, normally not change. So I can copy the zvm system (res spl pag) to other previously reserved dasds and start zVM from there in second level. Then You don't even need the page dasd. Just page to a temp disk attached to t he VM guest. Of course the major prereq is that you don't have any user data on the zvmres. The same thing I do in principle with zVSE DOSRES and SYSWK1 too. This way I have always a fall back when there are problems after system changes. In fact we do, even DISKACNT and EREP are not on RES. When we migrate a V M, ie zvm520 to 540, we build new res and spl DASD. Then these DASDs are cop ied to the production VM DASD ranges and we can IPL from the new DASD. The sa me we also use for VSE. And indeed, fallback just requires to IPL from the o ld DASD. But I also want a process that can be used when only a few members are changed. Then I only have to distribute a few members instead of a full V M system. This update is somewhat easier since only a few disks are to be updated. It all depends on the amount of changes. Even more so when CP is not touched. For instance, a PTF on PTK could only require the coding (5VMPTK40 201) and perhaps the helpdisk (MAINT 19D) to be updated. No IPL required in that case. In this case, there are 8 minidisks that need to be changed, not counting OSASF and HCD. On most of them only a few CMS members are changed. So her e we update the members (a few minutes) and SHUTDOWN REIPL (one minute). A lot quicker than rebuild the VM and IPL from a different DASD. Regards, Berry.
Force user into dispach
Hello listers, We have received a fixtest from IBM for testing but we need to recreate t he problem on our test environment. So far we did not succeed in recreating the problem. As it turns out we need to get one or more users into the dispac h queue without using CPU cycles. The problem on our production systems looks like to be caused by linux guests that are a bit misbehaving on VM. Even while they hardly use CPU t hey remain in the dispatch queue. My guess would be because some tools keep t he machine busy with query requests. Our test environment doesn't have any guests that remain dispatched at al l time. So I need to get a user, either CMS or VSE, to wakeup as often as t o force the guest to remain in the dispatch queue. But the catch is that th e guest should not use CPU, so a looping user won't work here. Any idea's h ow to do this? Regards, Berry.

Re: Postscript printing with RSCS and TCPIP
Hello David, 1) remove the PORT=9100. Port 9100 is the HP socket printing protocol, not LPR/LPD. The two are not interoperable, and RSCS doesn't know squat about the HP protocol (it'd sure be nice if RSCS got IPP support -- hint, hint) I tried without PORT (therefore with the default 515) and now at least I get the output. Maybe a bit of tuning is required to get the correct forms et c. 4) Seriously think about using a Linux guest to front end the printers. CUPS gives you enormously more control over the printers than RSCS does, and any printer you buy will be tested with it, because that's what the Mac support is -- Apple owns CUPS now. In that case we still need to print to some printserver. And that was jus t the problem. But I agree that a linuxguest could help us in some way. We do have linuxguests so we could setup one of them (an Samba server) to also serve as printserver. Thanks, Berry.

Third level VSE
Hello listers, Before I begin, yes I know third level will cost us. Since SIE doesn't ge t down to the VSE we do not benefit from that and all CPU has to be emulate d. We have moved an old VM/ESA 2.2 with VSE 2.3 to a new z890 machine. Obviously this level of VM can't run on zseries so we have put the VM int o an zVM 5.4 LPAR. It does run and since they came from an old (ESCON) mach ine the batch (mostly IO) runs very good. We did expect to see some performance penalties and we already sized the machine to twice the MIPS they used to have. And for the most part the gu est VM has a TV ratio between 1.9 and 2.5. Usually during batch the TV is jus t above 2 but during online hours we also see a TV above 3. There are a few transactions that have a very bad performance. (from 2 seconds to 2.5 minutes) The time also depends on the other load in the VSE (or perhaps e ven in the CICS). We have been playing with lots of settings. Such as, two virtual CPU's in the guest, two virtual CPU's in VSE with TurboDispatcher, one dedicated C PU to the guest VM. Any ideas on how to speed up the guests? Other than migrating the guest V M to the zVM 5.4 host? TIA, Berry.
Re: Third level VSE
Hello Kris, The guest runs with attached DASD so MDC is not applicable in this case. It doesn't look like IO is the problem here. But obviously any command processed in the guest will cause double the load in the host VM. So I do agree to avoid as much as possible. I don't know if MDC in the guest is possible or acceptable. Paging is not an issue. The host has 1G, the guest has 512M. The VSE runs NOPDS and the guest VM doesn't page. Yes, we run PTK. Running in the current config the guest VM can run up to 100%, and it does. When we assign 2 virtual CPU's to both VM and VSE (and start TD) we have seen the guest running up to about 190%. Also VSE does show processing at 100% CPU. But even an increase to 2 CPU's doesn't lowe r the transaction times for the transactions in question to an acceptable l evel. Regards, Berry.
Re: Third level VSE
Geert, Do you mean: attached to the VSE-guest or to the VM/ESA-guest? If attached to the VSE-guest: is there still a real performance benefit in attaching dasd to a 3rd level VSE-guest? Attached to the guest VM. I don't know if there would be any advantage in attaching to third level, other than an as-is move to a new location. Anyway, MDC has the potential of giving your VSE-throughput a real boost (it did in our case), so in order for the VSE-guest to benefit from MDC in the VM/ESA system, I would: - in the first level z/VM: attach the dasd to the 2nd level VM/ESA guest. - in the 2nd level VM/ESA: attach the dasd to SYSTEM, and define fullpack MDISKs for the 3rd level VSE guest. But would that also boost non-IO load? I expect the problem is CPU load i n some stupid program. In that case any MDC wouldn't help me for that. The only advantage would be an improvement of the batch processing. Also, if enough storage is available in VSE, add more buffers to your CICS LSR-pools and/or database system. Storage enough. We have 512M spare in the host VM that isn't used. And th e VSE runs NOPDS so we can increase it just by adding virtual storage in th e VSE guest directory. If VM runs out of storage (or starts paging at any serious level) we can add virual storage to the guest VM. Regards, Berry.
Re: Third level VSE
It looks like we were a bit fooled by the customer. After a lot of discussion it looks like it is not only CPU constrained. And also, at least in part, they already had problems in the old machine (and they forgot to mention that little detail). It used to be just acceptable but with the current overhead the performance dropped too much. As for your questions, the LPAR is the only one in use on the hardware. The VM guest is the only machine running any actual load. Others are DIRMAINT and a CMS servicemachine, things like that. The VSE in the guest VM is the top user. We did find that when the guest had been given two CPU's. Most of the time the LPAR ran at just over 100%. Sometimes it spiked to 120%. Once the VSE got it's second CPU and TD the load went up to close to 200%. So we can conclude the VSE is the top user here. Tomorrow we move the guest into an LPAR on a z9. Perhaps that would give us a faster CP. We have to look into the caching, like you and Kris suggested. Perhaps that could also give us some additional speed. And we also look into other configurations that would normally not do that much but it could be just enough to get an acceptable performance. Thanks, Berry. Dieltiens Geert schreef: Well, if the problem is caused by a CPU-intensive CICS-program, then I would expect that you would have seen that problem on your old system as well (when we put a really CPU-intensive CICS-program into production, we get calls from frustrated users immediately). But you'll need a CICS monitor to look into the resource usage of your CICS-transactions... A couple of other things to consider regarding CPU-resources: - is the VM/ESA guest the only (heavy) guest in the z/VM system or is competing with others? - was CP SET SHARE set appropriately for this guest in the z/VM system? - did you provide QUICKDSP for the VM/ESA guest in the z/VM system? - does the LPAR get all the resources you think its getting (check the Change Logical Partition Controls task or the activity display on the HMC)?

Re: Third level VSE
Ed (and Tom), Well, to be honest, about a year ago I already suggested to try to migrate into an zVM 5.x. And just before we moved the VM 2.2 I did repeat that suggestion. But according to some it would be too much of a risk. I guess it's a political risk, not a technical risk. And besides that, we were given too little time to plan a test on zVM before the move. But that's just my opinion. If it was up to me we would be on 5.4 next week. Anyway, as far as I can see it (I don have access to the detailed internals of the VM system) the only two risks would be ACF2 and VTUBES. And there is some external package I can't determine what risk it would have on zVM 5.4, I don't know if it is just CMS or that it does have some interaction that would require some VM/ESA level instead of zVM. ACF2 would require a new release and I don't know for sure what it would mean for VM 5.4 and VSE 2.3, if anything. But in all cases, we could just move the USER DIRECT into our host zVM 5.4 and try it.

Re: install z/vm 5.4
We have a dedicated install environment. So a new zvm gets it's own guest system. A distribution system that contains directories and local configuration members is used for building new VM images. When we build a new VM, or rather build a new respack, we copy (DDR and/or CMS COPY) only those minidisks from the installation image we actually need in our production VM's. Some minidisks are rebuild with our own code. Such as a PROFILE EXEC on the AUTOLOG1 191 or a dedicated configdisk for CMS services. That will leave us with 1) a respack with only IBM code we need for production images and 2) a dedicated spool pack for this zvm version. The respack doesn't hold any data we want to keep (for instance EREP, MONWRITE, DISKACNT etc) and other DASD do not contain any minidisks that are part of the IBM code. The directory gets loaded with the current production directory but obviously with the new IBM minidisks (the minidisk extents usually do not change in a new version so we take the old directory and change the volumelabel for the respack). Because the code is separated from the data we never have to copy datadisks from a live production image. The only thing we have to move during a migration are the spoolfiles from the old SPOOL pack. Obviously it will take some time to sort out the minidisks but it will save a lot of time when building or migrating a (new) VM. Regards, Berry. Crabtree, Anne D schreef: When I installed and customized z/vm 5.3, the only things I changed on the respack were MAINT, TCPMAINT, and AUTOLOG1 stuff. Everything else, like linux instances 191 disks, DISKACNT and ACCSRV 191s, ESAMON’s stuff, etc, I put on the 530W01 pack.

Re: VMSERVS and RMSMASTR
VSE does, to some extent. When you SIGNAL a VSE it will show the message in the hardcopy. But VSE itself doesn't react to the message. It is up to the VSE (FAQS for instance) to trap the message and issue the commands to shutdown VSE. Actually just like linux. The SIGNAL compares to the CTRL-ALT-DEL but it is up to linux to trap that key sequence and switch to init.0. Berry.

Re: Support of z/VM and zLinux environments
Hi Nick, And how is that working for you? At our shop we also provide the guest and the 'dark side' does the install and support for the guests. But they reguraly tend to work just like in the PC world. Meaning, ask for lots of memory (cache a lot, minimize IO, never swap) and install resource consuming apps (cron every minute or an app that has an keep-alive every milisecond).

Setup XLINK
Hello Listers, I am looking into XLINK. The main goal is to be able to determine if a minidiskextent on DASD is already in R/W use on a different VM. This way we could provide for an easy switch for linux guests from one VM to another. We do not setup the full CSE here. SPOOL and DIRMAINT are just for their own VM image. Now I have found that I need: - XLINK_SYSTEM_INCLUDE for every VM system. - XLINK_VOLUME_INCLUDE for every DASD volume. - XLINK FORMAT the DASD to enable the volume for XLINK usage. Do I need more? For instance, it could be that there are multiple minidis ks on one volume and that the linuxguests in question are spread across the 4 VM images. Should the DASD be set to SHARED for this? As I understand it linux doesn't require the disks to be SHARED but I'd like to be sure. Are there any other issues I should prepare for? TIA, Berry.

Re: z/VM 5.2.0 on z10
Hello Dennis, Is there a reason not to install 5.3 over there, other than management? It has been around for some time, even the new 5.4 is available now and 5.2 is going out of support next year. So I would think you would be better off with 5.3 for several reasons. If anything just because you already have 5.3 running. But also remember you'd have to upgrade in a few months to stay on a supported level. If management is concerned about the 'safety' of their system that would be of a bigger concern to management if you ask me. We have decided to install 5.4 in the next few months to replace our 5.2 systems. Even when we normally would install a release that has been around for some time, I think 5.4 would give us some improvements we won't get with 5.3. And it will at least be supported longer than 5.3.

Re: VM HiDRO
Hello Alain, It does take more time but not too much more space on tape. Well, if you use compression that is. We have set compression on the backup's and they do not take that much more space. But be aware that compression does take some more time and CPU. Our DR backup's created with VMIMAGE do contain the free space and that is what I want. I'd like the DR backup to be a perfect copy of the current situation. And also the CMS daily/weekly backup will dump a minidisk if it is not an CMS formatted volume. In that case the minidisk will be compressed and dumped. Formatted free space will compress very good but if the free space is not formatted then the old data will be dumped as if it was active data. But, as is already mentioned, if you do not want the free space to be dumped then you have to use the utilities for VSE itself. Regards, Berry. Alain Benveniste schreef: I would like to know if we are some to use the CA HiDRO product to backup VSE and/or VSE DASD.

Hello August, Why should you also use DDR? Hidro has the VMIMAGE backup and this is a lot easier than the DDR's. When we installed Hidro it was to replace Dynam/B for CMS daily and weekly backups.

And the VMIMAGE is in use for a full VM/VSE DR backup so also our VSE is included in the dumps. In the end we still do LIBR and fastcopy, just to be sure, but our DR relies on the VMIMAGE.

Re: Need some help with REXX EXEC
Are you sure? In that case I must reopen my issue with IBM because it doesn't work like that for me. And even IBM told me works as designed. When I issue a CP SIGNAL I must specify the time with the within option. The linux machine will be logged off, either by itself within the specified time or it is forced by CP when the specified time has passed. If for any reason the linux guest will not shutdown, for instance because some user is still logged on to the database, the machine might as well be forced by the operator with the same result. And the same is true for a VSE guest. And even for VM itself. If you signal a VM, either CP SIGNAL for a guest or a signal from the hardware, VM will shutdown without any concern for the guests running in that VM. In the case of a shutdown exec, I tried to set it up some time ago. I noticed that a linux guest or a guest VM would be forced whenever it took too long. And I even didn't try it for my VSE guests. So yes, using SIGNAL will help to shutdown your VM but do not expect your linuxguests to survive the proces. If they are forced you could end up with filesystem errors that will prevent an IPL the next time. And what about a batch job that is forced and will leave you with a database corruption? So I removed the idea of SIGNAL, both from the exec and from my mind. Now we issue a shutdown -h on the guest and wait for the guest to log off. If it didn't before a set time the VM shutdown is stopped and the operator must investigate why the guest isn't logged off yet. Regards, Berry.

Re: WAIT STATE
Hello Terry, Have a look at the CP message HCP1010W and you will find that you do not have a console. Either the correct console has not been definied in the SYSTEM CONFIG or it is not available. It happens to me quite often when I IPL an LPAR in a guest VM and forget that I need to set the console to my virtual 0009. Most of my systems have also 0009 into the system config but some don't (sigh). So either include your console in the system config or specify CONS= in the SALIPL screen. BTW. Often a disabled wait will show the CP code. So if you get a 1010 or a 961 (the latter means SYSTEM shutdown complete) then try HELP HCPxxxE, -W or -I on a different VM to see if that code is explained. Or take the CP Messages and Codes to look for the number in the CP messages chapter. Regards, Berry. Martin, Terry R.

SWAPGEN EXEC
Hello List, The past day I have tried to get the new version of SWAPGEN into my VM bu t no success so far. I have tried every way I can do a filetransfer but every time I end up in a file I can't use on VM. Can anyone send me the VMARC-ed version of the current SWAPGEN so I can continue? I do have the old version here but there seemds to be a problem with my VDISK swap so I'd like to try the newer version. (TIA) BTW, when I look at the mailable I see the filelist of the included files . The RXDASD MODULE in mailable archive looks like to be from 3/15/04. I to o have a RXDASD but that one is dated 18/11/95 and that is also the one fro m the IBM VM downloads. Is this RXDASD a different version or are they the same? I've looked into the comments made here in June, and I have to agree with the comments Adam made (to go back to the VMARC format). IIRC, VMARC was recommended to use because of the fact that ASCII to EBCDIC translations vary among the various file tranfer methods. (Either FTP or IND$.) So by replacing VMARC with MAILABLE to avoid the need for some extra tool and/o r to overcome less than default record formats, the transfer now relies on the fact of how your method of transferring files will handle ASCII to EBCDIC translation. IMHO this is much harder to solve than a faulty recordformat because the file itself will be altered by the transfer. At least with VMARC or CMS packed I know what recordformat it should be (either Fixed 80 or 1024) and can FBLOCK it after transfer. And because these files must be transferred in binary the file itself should not change by the transferprocess. Regards, Berry.
Re: SWAPGEN EXEC
Hi Dave, The SWAPGEN creates the VDISK and the zLinux does accept the disk. But swap is not activated on the disk. To activate the swap I have to issue a mkswap before swapon. And after booting the guest it must be done again. I don't know if it is a problem with swapgen, with linux or some fstab issue. So before troubleshouting, I want to replace the current swapgen with the newest one and then test to see if it helps. I noticed that the vdisk in linux is reported by /dev/dasdk and a partition on /dev/dask1. But from the docs I understand that the disk in FBA should be used as /dev/dasdk and not dasdk1. Quite strange, we already have some linux images with a vdisk swap and nobody has complained about the swapdisk. Thanks for the swapgen file. Tomorrow I'll test it with this one. Regards, Berry.

Error handeling (Was: How to stop PIPE STARMON)
Hello Rob, Are you sure this will work in all cases? The SIGNAL ON ERROR will react to any non-zero returncode. STREAMSTATE ca n have returncodes 0, 4 and 8, and it looks to me that all three are acceptable, at least in my case. Only rc=12, stream not connected, is indeed the returncode I will trigger upon. But the SIGNAL ON ERROR will exit the stage in all returncodes other than zero. But more in general, there are more commands that will exit a returncode based on their function. WAKEUP for instance. Just a small test confirms this: signal on error 'wakeup +00:30 (cons' say rc error: exit rc The result is that wakeup will return rc=2 when the timer expires and 6 when the console interrupt is received. In both cases valid returncodes, or perhaps required returncodes, but in both cases the SIGNAL traps the 'error' and skips the SAY rc command. In such cases it looks like errorhandeling should be coded for every individual event instead of a general error handeling trap. Regards, Berry.

Re: How to stop PIPE STARMON
Hello Kris, You are right. I had just changed an existing rexx that was constructed this way. Or rather, I had put a READTO into the rexx just to be able to be able to process the input before it enters a pipeline in the rexx. And indeed it would be better to PEEKTO/READTO or even more so, to check returncodes. I don't mind to delay records here, the stage writes records to disk and doesn't output them to an output stream. But the original, as well as my new one use 'CALLPIPE *:' rather than 'READTO input ; CALLPIPE VAR input,'. So in this case the input is not checked. The jeremy stage did note that inside the rexx stage a callpipe specs was in wait.locate and a lookup wa s in wait.locate but nothing about the returncode of the READTO command. An d I didn't trace the rexx itself in that detail so I didn't notice the rc 1 2 of READTO. I did now and indeed the return code is 12. Just a test with CALLPIPE *: reveals that the CALLPIPE do not end in a returncode so even when the input stream has severed the callpipe *: doesn't notice it and doesn't set the pipeline returncode. Instead it continues processing. So now, with the connector in the callpipe I do need to check my input stream before the callpipe connects to it. Regards, Berry. On Mon, 9 Jun 2008 15:08:05 +0200, Kris Buelens [EMAIL PROTECTED] wrote: 'STREAMSTATE INPUT' should not be required here... My guess is that process has set the returncode to 0, so your do-loop condition check is not testing the return code of READTO. The pseudocode also suggests your stage does delay the record. You should code it like this: 'PEEKTO INPUT' /* Get first record, without consuming it */ Do while rc=0 process 'READTO' /* consume the handled record */ 'PEEKTO INPUT' /* get next record or stop */ end
How to stop PIPE STARMON
Hello list, I'd like to replace the MONWRITE service we use now with a way to only save selected monitor records to disk. So I use 'PIPE STARMON MONDCSS SHARED | COLLECT' to collect and write selected records to disk. But in order to stop I must issue #CP EXT. I have been testing with other ways to stop STARMON in some way, such as GATE or PIPMOD but so far I am not able to stop the PIPE other than with #CP EXT. I would like to have some way to stop the machine in a more controlled manner with some command like MSG userid STOP or with a secondary console command. Currently we use SECUSER to MONWRITE and then issue MONWSTOP to stop the monwrite machine. According to the doc's I could use GATE or PIPMOD in some way to stop the pipeline and therefore to stop STARMON. And the PIPELINE package also states HMONITOR to stop the STARMON stage. Based on the GATE stage description I coded a pipeline but it still doesn't end. PIPE literal +10 | delay | a: gate strict \ starmon mondcss shared | a: | collect So how would I adjust this to be able to end the STARMON stage? TIA. Berry.
Re: Linux shutdown and DoD restrictions
Hi Charles, Also note that SIGNAL can potentialy be dangerous. If for whatever reason the linux machine doesn't shutdown within it's timeout it will be forced when the timeout expires. When you use SECUSER and SEND you still are able to issue commands to the linux image, for instance to react on some errors before you finaly shutdown/logoff the guest. Regards, Berry.

Re: RSCS question
Yet it also states: Remote Spooling Communications Subsystem (RSCS) V3.2.0 (5684-096) has bee n repackaged and is now available for licensing under International Program License Agreement (IPLA) terms and conditions.

Re: MONWRITE files
Hello Alyce, As Mike said, looks like a upload error. I guess these are from the IBM VM packages, in that case upload to VM in binary mode, Recfm fixed and lrecl 80. If you can't upload with specifing recordlayout you also can upload in binary and use the PIPE FBLOCK to restore the correct layout. (Upload binary and next issue 'PIPE MONVIEW VMARC A | FBLOCK 80 00 | NEWFILE VMARC A') I use this because my ftp client doesn't provide the recordlayout so I end up with 8K blocks instead of fixed 80 byte records. BTW, perhaps you can use this also on the files you now already have on your mindisk. These files usually hold more than one file. I assume, based on the console messages, that only a part of the files (monview script and cp2kvmxt exec) is now on disk. At some point, either at the end of a record or at the end of a file invalid data is found. So delete the files that were unpacked, upload the VMARC files again and unpack again. Regards, Berry.

Re: Performance problem Linux under Zvm
Hello Dave, In either case, if a linux (zlinux or intel) gets 768M it will eventually allocate all storage it can get. If not for applications it will use the 'free' memory for datacache. So in that repect, yes, the linux will use the storage you assign to the guest. But as for if the image really needs the storage, that will depend on the application you are running in the guest. In some cases you really need the storage but some applications offer the requirements to be set. Oracle for example can set buffersizes. I always try to convince the linux and/or application owners to request less storage for their linux image. Try, but not always successfull. Our zLinux machines run from 200M up to about 6000M. The first are small machines such as installation and SSL, the latter are large oracle machines. We run the linux images in two VM's of 10G each. At least you're not the only one who has seen this. We also have found the situation where we over allocated the VM image. That's not bad, in fact it is our unique selling point, but if SRM is not set accordingly you'll find guests in the E-list and start to wonder why a guest will stop processing. Evaluate your LDUBUF and STORBUF and also make sure you will have enough page space to hold all of your (vitual) storage needs. Regards, Berry. O'Brien, David W.

Re: Using WakeUp to cycle a zLinux instance
Hello Rob, I agree that FORCE would not be an option. In case of the linux machine IBM advised (see below) to setup a secondary console user to shutdown a linuxmachine and still have the option of communicating with the guest in case of problems during shutdown. This could also be used in a wakeup where some wakeup machine issues a shutdown -r on a linux console. But for the restart triggered by signal, are you sure you could do that? A SIGNAL SHUTDOWN LINUX01 WITHIN 300 will log off LINUX01 after 300 seconds or before that if the user reports a successfull shutdown. So a SIGNAL SHUTDOWN will eventually force the user anyway. When the user is rebooting, is the signal then canceled somehow? I had a discussion with IBM on that some time ago. I'd liked to see an option in signal to prevent the shutdown of guests when they do not shutdown within the timeout period. But IBM did not follow me on that. When a forced user in not acceptable (databases or jobs cancelled while processing) they advised not to use SIGNAL. This is true for zLinux but also for guest VM, VSE and SFS (all of them can trap the signal.) We had this issue for linuxguests that did not shutdown within the timeoutperiod due to running processes on the database. Also, A guest VM will signal users within VM (usually only the VMSYS* filepools) and then shutdown regardless of the successfull logoff of other services in VM. A VSE issues only a message in the hardcopy and some eventprocessing (FAQS-ASO comes to mind) has to ensure the correct shutdown of services and jobs within VSE. In all of these cases the guest user could still be shutting down when the timeoutperiod passes and that would be much the same as using FORCE in the first place. Regards, Berry.

Re: Webshare CGI will not run using SFS
Richard, Recollection is fuzzy, but I believe you can have CGIs and SFS hierarchy handled by the same HTTPD v-machine, you just cannot have CGIs living in an SFS-defined-only kind of space. For CGIs to be executed instead of serv ed out (like plain files), they must reside on an ACCESSed disk or in an ACCESSed SFS directory and be listed in a hand-crafted FILELIST. So the key here is the accessed directory. In both cases the server is SF S only. The first try had all files dumped into the root and accessed it as A. The second uses the full directorystructure and indeed doesnot access the htbin directory unless it needs to. Perhaps if I access the htbin directory before starting the server. Ah, I guess I'll be playing a lot today. :-) If you can think of a way around this, you should code it and contribute it. :-) Kris did have a way around it without any change in coding. The fact that the CGI is called in a slightly different way doesn't matter too much. Just update the links and run it. Perhaps it would be nice to have the server react the same in either case and for that to happen I'd need to dive into the coding. If only I had 30 hours in a single day... Thanks for your comments and for your great webshare coding. Regards, Berry.
Re: Webshare CGI will not run using SFS
Kris, Ah, that's it. For the CGI to process from an accessed disk you can request the page http://xx/somedirectory/somecgiFN. But when in SFS you need the path as you mention it. It looks like this could be working. But i'll have to look into it some more. Running CMSHELP would get me the CMS HELP MENU in the single directory install but it produces an error on the SFS installed server. CMSHELP: TASK HELP FPLDSR146E File HELP HELPTASK * does not exist FPLMSG002I ... Processing ADDPIPE HELP HELPTASK * | *.INPUT: FPLMSG003I ... Issued from stage 2 of pipeline 1 FPLMSG001I ... Running REXX CGI#TEMP CMSHELP?CP does give me the help page on the CP command. So in any case, error or no error, the CGI gets to be processed. Anyway, like Richard mentioned, i'll have some coding to do I guess. Thanks, Berry.

Webshare CGI will not run using SFS
Hello list, I have been playing a bit with the Webshare package from Rick Troth. It has been succesfull so far but now I ran into a problem running CGI scripts. My webserver machine, HTTPD, is an SFS only machine. (IPL CMS PARM FILEPOOL VMSBSFS) I started with all files in the root of the HTTPD machine. This works as it should, filelists are ok and also the CGI processing is working fine. HTBIN FILELIST is available, the CGI files in there are listed as *CGI to enable execution of the script, and cgi-bin points to HTBIN so I can run CGI like /cgi-bin/CMSHELP. I can get the CMSHELP in my webbrowser. No problem there. Now I have setup the server to use the .webshare directory and moved the webfiles into .webshare and subdirectories (like .webshare.vminfo and .webshare.htbin). This way we do not have to use the FILELIST files anymore. It makes adding files and directories much easier. I can access the regular webpages (home.html, vminfo.html etc). But a CGI is not executed. I've tried several ways but so far I was not able to get the CG I to run. I guess some configuration has to be set to be able to run CGI in an SFS based structure the same way as it does in a single disk configuration. How can I get the webserver to run an CGI exec instead of sending me the file itself? TIA. Kind regards, Berry.

Basically, list all spoolfiles (RDR, PRT, PUN) and select all files you want to delete. At the end we specify users and select how many of the files are to be kept. You can code some kind of selection inside the locate/sort/drop sequence. I did not have the time yet to make something fancy to replace sfpurger functions. (Like a real select based on date or some config file like SFPURGER has). As for SBM or OPERATOR we want to keep 2 weeks of consolelogs. The consolelog is closed daily at 00:00 for these users.

Define NIC and COUPLE
Hello list, When I define a NIC for the linuxmachine I use something like: DEFINE NIC F00 TYPE QDIO COUPLE F00 SYSTEM OSNLINUX In the directory the NIC is specified as special. In one machine we have defined three NIC's. F00 coupled to AOSN, F10 coupled to AOSNBU and F20 coupled to OSNLINUX. The F20 was created to mov e the linuxmachine to vswitch. F00 was the old connection to guest LAN. Today we had to disconnect F00 from the guest LAN and then redefine F00 t o connect to the Vswitch. Then the F00 would replace the F20 device and the machine would be moved to the vswitch. I have found something I can't explain. The NIC F00 was coupled to AOSN just after the DEFINE command, no couple was needed. But we wanted the NI C to be coupled to OSNLINUX so the couple to AOSN was not correct. I did no t expect the define to automatically connect to the guest LAN. What could b e the logic? Did I have to UNCOUPLE first? Thanks, Berry.

Re: OS/390 as zVM 5.2 Guest on z9 ??
Rick, I don't think it matters what OS/390 release is running. But the OS/390 V2R10 is the first to be able to run and exploit the 64bit mode. In this case the OS/390 is V2R9, that would qualify the machine as ESA/390. So it can't run 64 bit but it can benefit from the 64bit functions of z/VM 4 64bit that will increase performance of the Host VM, such as increased storage. Regards, Berry.
Re: TCP/IP Message
Hello Alan, That would get me to a question, are buffers that are dynamically extende d automatically reduced once they're no longer needed? As you state, more buffers could have impact for other users. So suppose we would have a sud den need for larger buffers to perform some action. If the action is finished and the larger buffer still remains it too would have an impact on the available storage. Regards, Berry.
Re: DASD second level
Hello Anne, Just some things that popped into my mind. VMTEST 191 and looks like this: USER WVLNX30 WVLNX30 512M 1024M G ..snip.. DEDICATE 0A81 163C DEDICATE 067E 165F VMTEST's USER DIRECT on first level: ..snip.. MDISK 163C 3390 000 10017 LX163C MR MDISK 165F 3390 000 3338 LX165F MR The guest VM has a minidisk of 3338 cylinders. Shouldn't that be 3339 cylinders? A 3390-3 has 3339 cylinders. I would guess to have either 001 3338 as a minidisk or 000 3339 for a full pack disk. Secondly, in this case you dedicate the 165F to the linux machine, so fro m cylinder 0 through 3338. Wouldn't that overwrite cylinder 0, thus replaci ng the CP volume information with whatever linux would like to see? Our zLin ux guests format the volume with a label something like 0x0200. Should that label be placed on cylinder 0 the hosting VM (either host or second level VM) we wouldn't be able to find LX165F afterwards. And the last point, perhaps not applicable, beware of running 3rd-level guests. They don't perform as well as second level guests. The CPU overhe ad in 3rd level is very large due to the fact that SIE assist doesn't work a t that level. (Assuming you run in LPAR mode, which is the only way on z-series today) We had an issue when we ran VSE guests on a guest VM. It turned out the VSE had on overhead ratio 1:2 or worse because all CPU had to be emulated by the host. The VSE couldn't use SIE assist in this configuration. SIE assist works only two levels deep, LPAR mode being one of them. Regards, Berry.
IPL without OPERATOR on console
Hello List, Last week we have seen an IPL that did not go the way I'd expected. It went OK, so VM is running, but it doesn't feel right. In the past our IPL procedures were: - Connect a terminal session to a console (let's say device 820) - load the LPAR on HMC with loadparm 820. - On the console the SA-IPL appears. - Change parameters if required and press PF10. - On the console user OPERATOR is logged on and some information on IPL i s displayed on the console. - User OPERATOR runs PROP and disconnects. Our new VM runs on a z9 machine. (actually 6 VM's on two machines) The IP L now looks like this: - Connect terminal - load LPAR - console turns to the VM logon screen. No SA-IPL, so also no way to specify a PROMPT or a different PARM disk. N o user OPERATOR to ask for start parameters (WARM, NOAUTOLOG) or to display the IPL steps, such as SPOOL init, and things like that. When closing the console log for operator I can see the lines I would expect to see on the console so it did all those things but it didn't show us that. It only happens on a z9 machine. Our VM's on z890 and z990 machines do show the SA-IPL during IPL. All VM's are z/VM 5.2 and use basically the same system config. So it looks like it has something to do with the machine or its configuration. Has anyone ever seen this? Any ideas as to what the cause would be? TIA, Berry van Sleeuwen.
Re: IPL without OPERATOR on console
Kris, The VM is z/VM 5.2 RSU 601. I can test it with one LPAR that still needs to be IPLled. We have cloned some VM's so apart from some small local tailoring (like nodeID and TCPIP configs) the VM's are identical. Let's play around a little bit. Either a s guest or native. You mention drag 'n' drop in the HMC. Does that indeed mean that the SA-I PL in that case is bypassed and VM is IPLled using defaults (CPLOAD MODULE, MAINT CF1 etc)? I must say, I haven't seen an HMC up close in 4 years now because that is completely separate from our department and even located in a different building. My last HMC was the one on a 9672. It is a real pleasure I must be able to help our operators during IPL but to have no recent knowledge of the newer HMC and it's procedures and capabilities :- (. Regards, Berry.
Re: PERFSVM
Hello Alyce, You might want to look at your MONDCSS segment. According to the message it is to small: FCXxxx446E Incomplete monitor data: DCSS too small. We have defined a segment like CP DEFSEG MONDCSS 9000-9FFF SC RSTD but the size could be different depending on your needs. Also make sure you enable the monitor, as it is done in the default profile exec in perfsvm. For more information, look at HELP CP MONITOR. Enable or disable events and samples to your need. Regards, Berry.
Re: How are you handling z/Linux
Hello Frank, I am wondering how everyone handles maintenance in your VM environment with your zLinux instances. We have a seperate install environment where we install and maintain our z/VM environment. If service has been applied (using VMSES, if possible not with put2prod) we copy only the changed items to our production VM's, about 15 VM systems. So we only need to restart those users that use the new coding. If CMS is serviced we need to restart users that use CMS (ie restart all users with a link to the MAINT 190). But a zLinux machine doe s not require CMS after the IPL of the guest (Nor does VSE for that matter) . So change of CMS does not require linux to reboot. We do not IPL unless C P has been serviced or a POR is required. A POR usually is only required fo r microcodeupgrades from IBM. If a change can be done without disrupting availability we will do that. So dynamic IO, set timezone, TCPIP OBEY, et c. Also to note we just implemented z/VM on two CEC's and plan to allow failover between the two machines. Our z/Linux environment is located on 2 VM's on two different machines. I n future all z/Linux images will use vswitch. The DASD can be shared. The idea is that we can start a z/Linux guest on either one of the two VM images. The linux customer will never know the difference other than perhaps a short outage during reboot of the guest. We did some tests but we havn't implemented this full scale yet. Note that this does only help you in a planned (or unplanned) outage of VM. If a z/Linux guest fails it will still fail on the other node. And keep in mind when the guests from the one VM are started in the second VM it will result in some performance degradation. Remember to have enough storage, paging DASD, reserved CPU etc on the failover VM to handle the added load. Regards, Berry.
Re: System Config : suggestion (corrected)
Hello Alain, We use an input file to select what DASD addresses should be online after an IPL. The file is basically a Q DASD. The file is read and attaches the DASD to system, dedicated DASD is left free and DASD that is not used is set offline. The only thing we have to do is (re)build the DASD file when a volume has been added or deleted. (PIPE CP Q DASD | DASD FILE D) It saves us from changing the system config every time we change the DASD configuration. If the files are located on shared DASD the DASD FILE can be named something like VMLXHW1 DASD for the VMLXHW1 node. This doesn't work when we have duplicate DASD volumes that are required during IPL. We have some VM's that still use the default zVM440 DASD volume ID's. When a default 440W01 or something like that has not been relabeled the 'wrong' addresses must be set offline in the system config: FBVM03: Devices , Online_at_IPL -, OFFLINE_AT_IPL 2100-21DF, OFFLINE_AT_IPL 21EA-21FF, OFFLINE_AT_IPL 2200-239F, OFFLINE_AT_IPL 23A4-23FF, Sensed - Regards, Berry.
Re: VM education
Hello Bob, You can also check out the redbooks section at www.redbooks.ibm.com. Ther e are some nice books (both redbooks and redpapers) that can be a nice handson for starters. Especialy the books related to zLinux are usualy written with the VM novice in mind. (http://www.redbooks.ibm.com/cgi- bin/searchsite.cgi?query=linux+and+VM) Regards, Berry.
Re: VM and CA-Top Secret
Hello James, You can download documentation at supportconnect.ca.com. In download - documentation you can find (almost) all manuals for CA products. But I guess you need a supportconnect account for this. I would advise to sign up for supportconnect anyway. We have two different systems using Topsecret. The first is a VSE installation. This topsecret spans 11 VSE's in 4 VM's. The topsecret file s are shared in these environments. User maintainance is performed on any o f the CICS systems online or in batch on any of these VSE's. It depends on my needs at the time. Online using CICS is easier. In batch I can use batch jobs to perform lots of commands in one go. The second system is a single VM with 4 VSE systems. The Topsecret files are shared between VM and the VSE's. We manage users from VM but we also could do this from VSE. From VM it has the advantage that I can use EXEC' s to perform commands. Just like a batch job in VSE. So how you want to manage users is a matter of opinion. I like VM but the CICS online interface has it's advantages too. As for sharing, I like that because we only have to maintain one security file. But if that is a possibility in your shop also depends on the requirements from the security department. We could convince our security officer quite easily and our user setup would also require a shared environment but some other shops are much tighter in such security rules. Regards, Berry.
Logoff force pending
Hello list, The past week my userid was in a logoff force pending state. Yesterday this status has changed. So I can use my userid again. But I can't figure out why my user was waiting to logoff like this. The system is our z/Linux production VM that is running z/VM 4.4.0 on a z990 machine. It all started when I tried to vary online two DASD devices. A query revealed that DASD 21EC and 21ED were offline. We have other DASD in the same ranges and on the same paths that were online. So I issued VARY ON 21EC 21ED. But I did not get a ready in return. But I could vary on these devices in a different VM. After some ten minutes I forced the user. Yes, I know, it was a risk. The logoff force pending was expected. I guess the IO associated with the VARY operation was still pending and therefore the user could not be logged off by CP. Nothing strange so far, other than th e question why the VARY did not appear to be processed on this VM. I looked for a way to solve this issue. But no advices I'd found were successfull. The devices I tried to work with were still offline so I could not VARY them offline. I could not query or tinker with CP Storage for my user (not even if I wanted to) because the VMDBK block was not available anymore. (A LOCATE returned with User not logged on) And beeing a 24x7 production system an IPL is out of the question. Yesterday an OSA device was removed from the configuration. At the same second my user is finaly logged off and ready for use again. (And yes, th e DASD is still offline so the command has not been processed at all.) Now, what I can't understand is why my user suddenly freed itself when a totaly unrelated device is beeing changed. Or why it turns out to be pending on an other device in the first place. As far as I know nothing has been changed on the DASD devices. And the OSA was not in use, at leas t not by my user. So a pending console IO is not the case here. Can anyone think of a reason why this has happened? Thanks, Berry.
