Re: RACF, setropts inactive() and long running guests
The way we handle this goes back a long way before the latest facilities to set NOPASSWORD were available. What we do is connect all users who are likely to be affected by this (long running servers etc.) to a specific RACF group. We then run a daily procedure in VMUTIL, that is authorised to list that group and issue an ALTUSER RESUME for each user in it. That is all that is needed. The user does not have to be revoked at the time and knowledge of the password is not needed. As we always use LOGONBY for any non-personal userid's, we should probably update our process to use NOPASSWORD, but this method may be useful for userids where you may, occasionally, need to know the password.

CPFMTXA VOLUME FORMATTING QUESTION
Hello all, I have a new DASD address which has to be added to z/VM 5.3 which was previously formatted with a z/OS format. I didn't do a CPFMTXA format. I attached the volume to system and DDR'ed a few minidisks over to the new volume. So, cylinder 0 of the new volume is not in CP format. The copied minidisks are O.K and I would hate to do the copies again. Is there anyway to CPFMTXA just cylinder 0 and then allocate the entire volume as PERM without loosing the copied minidisks? Thanks. _ LEGAL NOTICE Unless expressly stated otherwise, this message is confidential and may be privileged. It is intended for the addressee(s) only.

Performance question
If your VM system is at 101% memory usage, and you are overcommitted by about 14%, is it worthwhile to add a vdisk to a linux for swap space, or better just to add main memory to the linux? MA (Looking for opinions, thoughts, rationalizations, whatever. :)
Re: CPFMTXA VOLUME FORMATTING QUESTION
When you use CPFMTXA command, you can specify the from/to cylinder for your format command. Specify cyl 0 and then properly allocate the device as PERM. As a general procedure, I do not attach any new device to my system before I CPFMTXA the complete volume.
Re: CPFMTXA VOLUME FORMATTING QUESTION
Look at HELP ICKDFS, CKD COMMANDS, CPVOL. You'll use the command CPVOL FORMAT UNIT(cuu) VERIFY(serial) RANGE(0,0) VOLID(serial) It will default to PERM from cyl 0 to end of volume. CPFMTXA is just ICKDSF dummied down. Wish they had never introduced the command. Jim Howard Rifkind wrote: This is a MIME message.

OPERATOR insists on VM READ ?
Ok - this is an extremely basic question and I'm slightly embarrassed to ask it - but here goes: OPERATOR is not running PROP at this installation -- There was also no IPL statement in OPERATOR directory until I started futzing around -- creating a PROFILE EXEC to make sure OPERATOR console was spooled to the logs collector - and putting an IPL 190 PARM AUTOCR in the directory entry. However - once the PROFILE EXEC is executed -- OPERATOR goes into a VM READ (I'm watching via SECUSER) and eventually gets forced off by the system. I just realized that OPERATOR was not SYSOPER as I was doing this -- but it still doesn't seem normal that it would end up in VM READ .. Can anyone tell me if this is normal behaviour - or if I really need to execute something (do forever;CP SLEEP 1 MIN;end) to get it to stay out of VM READ? Thanks for any assistance.. Scott Rohling
Re: CPFMTXA VOLUME FORMATTING QUESTION
A CPFMTXA LABEL should do it for you.. Just label the volume appropriately -- And - Issue a CPFMTXA ALLOCATE to see what the current allocation is - and then get out of there if it's allocated as PERM (as I'd expect)..

Re: CPFMTXA VOLUME FORMATTING QUESTION
I haven't tried it, but I would expect that CPFMTXA LABEL or ALLOCATE would fail if the volume or at least cyl 0 had not been formatted with CPFMTXA. One important reason to use ICKDSF CPVOL or CPFMTXA on a volume in a mixed, i.e. OS and VM environment is that CPFMTXA or CPVOL will leave the OS space available label (can't remember what the number of it is) showing that there is NO available space on the volume. You don't want an OS system looking around for dasd space and finding an entire volume that's available.

After it came up I loaded the dump and just had a chance to see the registers - which looked very strange, when it crashed again. After it came up, checked the dump again and registers 1 and 2 contained: C3C8C5C5 E2C54B40. A rather unusual set of addresses in pre-XA days, and pretty unlikely even now. It took only moments for the light to come on; R1 and R2 contained EBCDIC for 'CHEESE. '! I loaded up the second dump and just had time to see another set of registers (not sure if it was R1-R2 or R11-R12) which contained D9C5D7D6 D9E34040. That translated to 'REPORT '. For some reason something clicked and I ran down to the data center to check. Sure enough, one of our just-added page volumes was mounted as 'PUBLIC' on one of the MVS systems. Another group was responsible for running CPFMT and adding new DASD to the system. We usually double-checked their work, but this case missed checking the new page volume. It had been INITed, but they had neglected to run CPFMT to place the dummy VTOC on it. So to MVS it looked empty, while VM paged out to that volume, MVS wrote temporary datasets on it, which VM paged in and tried to load as executable instructions. I still refer to this as the time the system crashed because there was CHEESE in the registers (sounds like a hardware problem)! ---snip--- I think we were the only VM customer to ever crash a VM system because we had cheese in our registers. It gummed up the works pretty well! ;-0 We were fortunate that the data loaded back from DASD was fairly obvious. It could have been much more difficult to resolve.

Re: Performance question
Best practices is to use Vdisk for swap, and reduce linux virtual machine sizes - not to buy more REAL z/VM memory unless you really need it. 101% memory useage means almost nothing.

Re: OPERATOR insists on VM READ ?
On Monday, 09/29/2008 at 12:46 EDT, Hughes, Jim [EMAIL PROTECTED] wrote: Does your IPL statement have parm autocr specified? From Scott's post, yes. However, CMS users that are XAUTOLOGed should NOT have PARM AUTOCR on the IPL statement. The reason is that XAUTOLOG will stack an ENTER to the virtual console on the assumption that CMS is going to issue a VM READ. The intent was for CP to automatically press ENTER. If CMS doesn't issue the read because of the PARM AUTOCR, however, the enter remains pending and the console is stuck with console input waiting or NOT ACCEPTED. At #CP ATTN will cause CMS to issue a VM READ, satisfying the pending console data and allowing additional console traffic. Unlike XAUTOLOG, LOGON does not stack the ENTER, so PARM AUTOCR is needed to avoid the VM READ at IPL. The PROFILE EXEC for OPERATOR would typically have - CP TERM MODE VM (system operator defaults to MODE CP) - SET AUTOREAD OFF The queued() and externals() functions provide the means necessary to build a PROFILE EXEC that can deal with PARM AUTOCR without regard to XAUTOLOG or LOGON.

It will use less if mem is constrained. Linux kernel for running on VM could be designed a little different from Linux kernel for PC in order to behave better with VM.

Re: CPFMTXA VOLUME FORMATTING QUESTION
Only if the volume label points to somewhere that used to be a VTOC that has not been overwritten. Unless things have changed in the last few years, the VTOC written when formatting the disk as a CPVOL does not go far enough. If the MVS DASD Storage Allocation Routine is interrupted while the checking for free space on the volume, a bit (formerly known as the DADSM Interruption Bit or DOS VTOC bit, currently known as the VSE bit, name DS4DOSBT in the F4 DSCB DSECT) is left on. The next time MVS attempts to allocate space on the volume, it will try to create proper free space records. It does this buy starting with an F5 DSCB that shows all space available on the disk. It then runs the F1 and F3 chains, allocating each described extent. Since there are no allocated extents on a CPVOL formatted disk, it shows the entire volume as being available for space allocation. There needs to be at least 1 F1 DSCB allocating the entire volume to a space-holder dataset to prevent this highly unlikely occurrence.

Re: SLES10 Client
While implementing the SLES exec for the SLES10 full-service server, it asks for a MAC address. (I thought the MAC address was automatically assigned. Why is it asking for a static address?) We are using OSA GB-EXP. You should respond no to the layer 2 prompt here. Nothing in the setup process needs layer 2 access. In general, it's asking so that it correctly identifies the interface you want to use. CP generates a random MAC for the last 3 bytes of any virtual interface (the first 3 bytes are set by MACPREFIX in SYSTEM CONFIG), so if you are going to use the layer 2 function, it matches the virtual MAC to identify which interface to use.

well service removal is never easy or automated. If this was a bunch of COR service it is easier to remove but never fun.

Question
Hi Over the last month or so we have had CHECK SUM ERRORS on 3 of our z/Linux hosts. This error stops the Linux host from coming back up after a re-boot or log off. After working with REDHAT they found that there was 2 bit over lay of what amounts to the VTOC which points to the UUIDs. Each time this has happened it has been the same over lay. The common thing on these hosts are that they all run Oracle 10g, REDHAT REL4, and FDR/UPSTREAM. When this happens we must boot in RESCUE mode and re-build the UUIDs (not sure of this process by Linux guy does this). I was just wondering if anyone has seen this type of issue. This is our POC but if this does not get resolved we will be hard pressed to move forward.

Re: Backing Off an RSU
Alan makes a good point - call IBM support if you are unsure how to proceed. There are documented ways to back off service with VMSES/E and they work well. This assumes you have not deviated from the standard Install and Service of course. Check out VMFREM. This handy utility will allow you to back-off full service levels. Fortunately if you did the RSU install using SERVICE, then it did good hygiene and did a merge of the apply disks which makes VMFREM work well. You will have to do VMFREM for each component, but that should not be too difficult. Do a HELP VMSES VMFREM or look in the VMSES manual for help/details about that command. Once you are done removing service with VMFREM, you will need to run the VMFBLD process (again) to built the new parts (ones w/o service applied to them). I hope that helps get you started.

Re: Backing Off an RSU
Thanks for the suggestions guys (I'll have to re-read VMFREM in case I can use it in the future). I was able to restore the system exactly the way I wanted it by selectively restoring extents from my DDR backup tapes, worked great. I'll do a level set backup after checking a few things before embarking on the work that caused this bit of a mess so worst case I can always fall back to the level set. :) I think I'll start taking daily backups on this system in development too just in case. :) -Mike -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of James Vincent Sent: Monday, September 29, 2008 6:20 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Backing Off an RSU Alan makes a good point - call IBM support if you are unsure how to proceed.

Re: CPFMTXA VOLUME FORMATTING QUESTION
That last makes for a good question. I do not have any guests other than CMS, GCS and TPF varieties, so I have no way to trace to see if it is still a problem. The only time I encountered it was in a non-VM shop. Fortunately, we were able to wrest the disk away from the system before there was any real harm. I had the onerous task of restoring the dummy VTOC using the then state of the art IEHDASDR and SuperZap. I cannot reproduce the situation here. The DASD Storage Management folks are adamant about not having VM volumes accessible to z/OS and vice-versa, which suits me just fine. That eliminates the only system I know of that has the potential to cause the problem. Regards, Richard Schuh -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Alan Altmark Sent: Monday, September 29, 2008 1:33 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: CPFMTXA VOLUME FORMATTING QUESTION On Monday, 09/29/2008 at 02:06 EDT, Schuh, Richard [EMAIL PROTECTED] wrote: Unless things have changed in the last few years, the VTOC written when formatting the disk as a CPVOL does not go far enough. If the MVS DASD Storage Allocation Routine is interrupted while the checking for free space on the volume, a bit (formerly known as the DADSM Interruption Bit or DOS VTOC bit, currently known as the VSE bit, name DS4DOSBT in the F4 DSCB DSECT) is left on. The next time MVS attempts to allocate space on the volume, it will try to create proper free space records. It does this buy starting with an F5 DSCB that shows all space available on the disk. It then runs the F1 and F3 chains, allocating each described extent. Since there are no allocated extents on a CPVOL formatted disk, it shows the entire volume as being available for space allocation. There needs to be at least 1 F1 DSCB allocating the entire volume to a space-holder dataset to prevent this highly unlikely occurrence. You need to open a PMR with the ICKDSF team on this if you're interested in getting it fixed (assuming it is still a problem). Alan Altmark z/VM Development IBM Endicott
VMARC download date
When one downloads a VMARC'ed package, the downloaded file (let's call it FUBAR VMARC in honor of the ongoing US financial crisis) ends up with the date and time the FUBAR VMARC file was created on your VM system. That makes it more difficult at a later date to download the same package and easily see if there are differences between the two files. It wouldn't be too hard write a new EXEC to compare the VMARC LIST output from the two VMARC files, but it would be a tool required to check another tool (VMARC). Would it make sense to add new function to VMARC to provide capture of the date and time the FUBAR VMARC file was created (or last updated), and imbed that date and time within the VMARC file itself? With such a feature (perhaps via a new trailer record such as :TLR to complement the existing file :CFF header records), a new VMARC command (maybe called RESTDATE?) could be used to both confirm that the whole file had been downloaded (since the :TLR record would always be the last record) and be able to use DMSPLU to RESTore the DATE and time to that which had been saved in the :TLR record. RESTDATE is just an example operand keyword - better suggestions would be most welcome. Obviously, RESTDATE (or whatever) would have to be backward compatible -- just reporting something like: No :TLR record present; the file was created before mmdd, or the file was truncated during download. (Where mmdd was the date and time that the new support was added).

Re: Backing Off an RSU
Sure. Easy for you to say. Just not to say it in one breath. :-) Mike Walter Hewitt Associates - Original Message - From: Alan Altmark [EMAIL PROTECTED] Sent: 09/29/2008 09:23 PM AST To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Backing Off an RSU On Monday, 09/29/2008 at 07:32 EDT, Rich Smrcina [EMAIL PROTECTED] wrote: That begs the question, doesn't this qualify as a usage; not defect? Hello? Support Center? Yes, I'd like to report that there is nothing in the Guide to Automated Installation and Service on the subject of removing service that I've applied using the procedures described therein. No references to remove or uninstall in the index. Yes. No. No. Yes. No, nothing. Yes, the word remove appears in the book, but not in this context. I think the book that tells you the preferred way to apply service should include a reference to the book (and section of said book) that DOES describe how to remove service. Since that information isn't there, what book should I look in to find out? Or if it's actually in this book, where is it hiding? Sounds like a documentation defect to me.

Re: VMARC download date
Maybe the :TLR record could optionally include a checksum of the entire file. I might not want to do that for every transaction I do to build a VMARC file, but when I am finished and it is ready to transfer to someplace else, I could see doing one last transaction to checksum the file, put the data in the :TLR record and display the checksum for my paper records. /Tom Kern Mike Walter wrote: When one downloads a VMARC'ed package, the downloaded file (let's call it FUBAR VMARC in honor of the ongoing US financial crisis) ends up with the date and time the FUBAR VMARC file was created on your VM system. That makes it more difficult at a later date to download the same package and easily see if there are differences between the two files. It wouldn't be too hard write a new EXEC to compare the VMARC LIST output from the two VMARC files, but it would be a tool required to check another tool (VMARC). Would it make sense to add new function to VMARC to provide capture of the date and time the FUBAR VMARC file was created (or last updated), and imbed that date and time within the VMARC file itself? With such a feature (perhaps via a new trailer record such as :TLR to complement the existing file :CFF header records), a new VMARC command (maybe called RESTDATE?) could be used to both confirm that the whole file had been downloaded (since the :TLR record would always be the last record) and be able to use DMSPLU to RESTore the DATE and time to that which had been saved in the :TLR record. RESTDATE is just an example operand keyword - better suggestions would be most welcome. Obviously, RESTDATE (or whatever) would have to be backward compatible -- just reporting something like: No :TLR record present; the file was created before mmdd, or the file was truncated during download. (Where mmdd was the date and time that the new support was added).
