Seinfeld's Contribution to the The Principles of Operation
There is only one place in z Architecture Principles of Operation where the word substantially is used. Even more surprising than its use is the fact that it appears immediately before the word "accurate". My interest in the reference bit, though passing, is sincere since I would like to hang my hat on the validity of that indicator. Substantially means " to a great extent or degree". In system z architecture, I am unfamiliar with this level of accuracy. For your reference (no pun intended) the paragraph in z POPS is: "The record provided by the reference bit is substantially accurate. The reference bit may be set to one by fetching data or instructions that are neither designated nor used by the program, and, under certain conditions, a reference may be made without the reference bit being set to one. Under certain unusual circumstances, a reference bit may be set to zero by other than explicit program action." Although Seinfeld had to have written the previous 67 words, it is possible (age 21 at the time) for him to have contributed the original paragraph from the 1975 POPS and simply updated the paragraph for System z. The 1975 paragraph follows. "The record of references provided by the reference bit is substantially accurate. The reference bit may be turned on by fetching data or instructions that are neither designated nor used by the program, and, under certain conditions, a reference may be made without the reference bit being turned on. Under certain unusual conditions, a reference bit that is on may be turned off by other than explicit program action. "Turned on" and "Turned off" apparently gave way to the more precise "set to one" and "set to zero" for those so technically challenged that on/off had lost all meaning. Think about it; the technical writers were striving for more precision in their description than the "thing" being described actually provided. Does anyone have a clue what sentences 2 and 3 (substantially) mean in either paragraph and would anyone venture a guess as to why, after 40 years of architectural excellence, the reference bit can't be more than "substantially accurate"? My curiosity is killing me. --. .- .-. -.-- Gary Dennis
Re: Question about DFSMS/VM - RMS
I have observed that when a tape is loaded into the I/O station, upon trying to close the door, it will not close easily. Of course this may not stop some determined operator/whomever from closing the I/O station door. I have heard stories from CE's that, with MUCH effort, the door can be closed.

As others have noted, the files coming from a medium or larger system with more than a few domains enabled can be quite large, but if your goal is to create a consolidated performance database in one place, it unarguably works. MXG is quite powerful if you are comfortable with it and SAS in general. I guess I'm not clear what the question would be. Can you do it? Yes. Does it work well? Yes, if you have sufficient disk and CPU. Would I do it again? Depends on what I was trying to accomplish.

Re: Migrating Backup/Restore and Tape Manager from 2nd level
I used the second level system to activate and configure DirMaint and RACF. My cut over into production is basically renaming the 2nd level volsers to production names and renaming the production volsers to an alternate naming convention via a 'lifeboat' system IPL'd in the interim. I have tested this successfully at our DR provider during an exercise. I've backed up EREP/DISKACNT/PERFSVM and I'm comfortable with how I'm restoring it to the new production system, but I'm second guessing myself on how I'm approaching Backup/Restore and Tape Manager. I wanted to backup the current production VM Backup & Restore Manager/VM Tape Manager environment and restore it to the migrated DirMaint/RACF environment once its been IPL'd 1st level/production. I had planned on using simple TAPE DUMP and wrote a REXX EXEC to automate the process, and backing up and restoring works _in theory_. Now that I've been working with Backup/Restore-Tape manager a bit more, I'm not so sure this is the right way to go. And, time is short. So, I was looking for some insight on how off the mark using TAPE DUMP to migrate the catalogs is. There is no sharing of the tape and backup catalogs. There is no communication defined between the 2 systems. Thanks again! -Tom Quay, Jonathan (IHG) Thu, 07 Oct 2010 05:06:36 -0700 I am not sure what you are trying to accomplish.

I am not sure what you are trying to accomplish. Doing maintenance on a solo VM system? Are you creating a second VM system? If so, are you trying to share the tape and backup catalogs between them? From: The IBM z/VM Operating System on behalf of Tom Duggan Sent: Tue 10/5/2010 9:17 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Migrating Backup/Restore and Tape Manager from 2nd level I have a 2nd level z/VM system that I've activated and configured DirMaint and RACF. The 2nd level system is a DDR copy of the first. 1st level production uses Backup & Restore Manager and Tape Manager. It sits inactive (not autologged, along with other service machines) 2nd level. Obviously, the 2nd level Backup/Restore/Tape is not in synch with first level. The initial plan was to backup _select_ 1st level minidisks and restore them when I cut the 2nd level system into production. By _select_, I mean only those minidisks that I saw current updates to. I'm now seeing that possibly might not be the best approach. Would it be better to backup and restore each and every minidisk for Backup/Restore/Tape? e.g. every minidisk for BKRBKUP, BKRCATLG, VMTAPCAT, TMTMM, TMRMM, et al? I did recently run across the procedure to enlarge/move the SFS tape catalog. Thanks in advance. Tom Duggan
Re: VM Monitor data processing
Derek, If you are in a position to, 'roll-your-own' then take a look at the PIPE STARMON stage. In a previous life I used this to good effect to do precisely what you are attempting - collect monitor data - roll it onto a transmittable form (NETDATA or whatever) and then ship via RSCS as a batch job to MICS running in z/OS. Given STARMON and some Rexx skills this is not a horribly difficult feat. Good luck! Jeff
Re: VM Monitor data processing
We ship all of the SMF data we collect and the monitor data I trying to get off the ground is only 2 or 3 domains. We have the capacity, and I am not concerned Linux etc. MXG can process it, and that is what I intend to use. And am trying to find others to do it this way.

Pretty costly to collect raw data, ship it to z/os and process it there. There are lots of installations that take the zVPS (Velocity Performance Suite) data and ship it to z/os from vm, and MXG supports it direct. Probably 1 percent in size. Other installations take our MICS file (probably less than 1 percent in size) and ship that to z/OS for processing there. Other vendors are in process to take the data as well for the same reasons (plus the get linux and other network data).

Re: [?? Probable Spam] Re: Strange performance problem
Since the high load is only on processor 0 the high supervisor state was to be expected: must be something CP decided it had to do on processor 0. Since you do have a performance monitor: does/did it show just a correspondingly higher load for CP on processor 0, in which case looking for a user with a high CP load percentage should tell you which guest caused the problem, or was it a case of the 'system' load peaking? Whichever it was: None of the processors were really highly loaded, so I'd expect the user who complained to have very probably been working with the guest causing the problem while the remainder was still ok. (You didn't say whether the whole system slowed down, but if it did then I'd put that down to a CP problem.)

Barton, As you know, we do have a good performance monitor. It is just that, unfortunately for you, it is not the one that you provide. Don't flame me for that one - it was a commercial rather than technical decision and I had no input into that. The fact remains that I can search the performance monitor we do have for information - if I have some clue what I am looking for. The system is peaking high supervisor state activity on processor 0 (we can also see this on the SAD display) for significant periods of time. I have exhausted all the likely causes that I know and I am now looking for new ideas on what to look for.

You learn > new stuff everyday. One also learns bad habits every day ;-) PIPE AHELP is what you want (and a recent PIPELINE HELPLIB for it). The help files shipped with CMS are normally less accurate and not always correct. You're right that the description of the CP stage does not state that you can't have an extra CP command as the argument when using the secondary output (the reason is probably that we'd lose the one-to-one correspondence between processing input records and producing something on the secondary output). | Rob
