Re: Ten Questions to ask a Prospective z/VM Systems Programmer
At the risk of beating the horse recursively... Looking at the thread, I think it would be an interesting approach to ask the applicant what the top-10 questions would be he or she would ask someone applying for a VM systems programmer job. It might reveal whether they follow the mailing list, whether they pick easy or hard questions, and whether they start something even when they are not fully sure about the details... -Rob

You don't. Virtual Reserve/Release emulates the real reserve and release CCWs when you have two guests in the same LPAR sharing an O/S or VSE disk.

Re: Ten Questions to ask a Prospective z/VM Systems Programmer
At a time my customer had some softwares that all required a shared minidisk with Reserve/Release (MIM, STK, ...), these softwares required two disks for safety; STK required 4 as we had 2 silos. With VM's restriction that real R/R works for a fullpack only,, it would have costed us 6 (or was it 8?) fullpacks with only a couple of cylinders used. So, I wrote a small CP mod to remove that fullpack requirement. A new restriction arose: no more than 1 minidisk with R/R on a single pack, restriction not enforced by my mod, we had to keep that in mind. Mod still in place on our z/VM 5.2 - till end june when my customer shuts down the last VM partition and I will be without z/VM work. Every virtual thing I built up since 20 years ago will stop living and be mummified on some DDR tapes either for a while or until z/VM resurrects to support Linux.

The other gotcha is that your mini disk must start at cylinder 0 to make the real reserve/release work. The other interesting thing is that for example RACF does not use reserve/release, but does try it to see whether the disk is shared.

Hmmm. It seems we are in agreement on that. My point was countering the statement that MWV was necessary and sufficient for sharing with other LPARs. It is neither necessary nor sufficient for that purpose. Making the disk SHARED through the config file or by command fills the role for that purpose; the V suffix in the MDISK statement fills it for virtual machines running in the same LPAR (assuming all other requirements are also met).

Virtual Reserve/Release emulates the real reserve and release CCWs when you have two guests in the same LPAR sharing an O/S or VSE disk. Real R/R would be of no help in that instance because it applies at the control unit level and reserves the device to an LPAR or, if running in basic mode on a pre z9 system, a physical machine. Any access from that same LPAR or machine is allowed. That is why Virtual R/R is needed when there are multiple guests sharing the same disk. Virtual Reserve/Release is needed when you have virtual machines that share a R/W disk with proper protocol. Real reserve/release is necessary when you share between LPARs. The combination of virtual and real reserve release is when you have multiple virtual machines as well as different LPARs (or systems). There is no shortcut for this. The other gotcha is that your mini disk must start at cylinder 0 to make the real reserve/release work. The other interesting thing is that for example RACF does not use reserve/release, but does try it to see whether the disk is shared. Careless configuration may cause it to take a long route where it should not, or may corrupt your database. Rob -- Rob van der Heij Velocity Software GmbH http://velocitysoftware.com/
Re: Ten Questions to ask a Prospective z/VM Systems Programmer
That works; however, it precludes the sharing of a disk among multiple MVS or VSE guests running under the same CP. If only one user needs access to the disk, then dedicate or attach are sufficient. You do need to insure that the devices shared this way are shared in the RDEV, either through the SYSTEM CONFIG file or via command. Would making the devices unsupported prevent the command rejects on reserve and release CCWs? Of course, doing that opens another can of worms.

If the MDISK is a fullpack minidisk (DEVNO or 0-END) then the minidisk is ELIGIBLE for real RESERVE/RELEASE. Isn't the check for start at 0 rather than full pack? I recall our RACF database sitting at cyl 0 and we had some other mini disks behind it. That works because RACF does not really do reserve/release. It is full pack, not start at 0. And, yes, RACF really does RESERVEs on ECKD volumes. He does not on FBA volumes and this is why database sharing is not permitted. When RACF comes up you can see the messages on his console telling you if reserve/release is available. Alan Altmark z/VM Development IBM Endicott

But you might use them as dedicated devices that are shared with outside (of VM) agents.

Re: Ten Questions to ask a Prospective z/VM Systems Programmer
I suppose it would differ based on whether you were looking for someone to train or was experienced, and what type of shop you have. For example, I might want someone with TPF support experience who could install the VSSI products and, if a dump is taken, determine whether IBM or VSSI code is most likely to be at fault. Another helpful factor would be whether the applicant had a good working knowledge of the hardware. Someone else may who has a VSE or Linux shop would have an entirely different set of criteria. Then, there is the operations support side. How heavily will the operators lean on the sysprog? Will this person be required to build and support tools that the users need and rely upon. Is REXX and/or Pipelines needed? This seems almost like a Bit type of answer - YMMV.
