Re: DLIB volume for SAD

In that case, you are taking a risk. We don't try to make SADMP upward or downward compatible across releases, so whether or not that happens to work depends mainly on what changes were made in the Real Storage Manager component. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM

Re: how to verify whether the volume is empty or not?

Hi Jason, Although it may not be exactly what you were looking for or thinking of, IBM added a parameter a few years back to the INIT command of ICKDSK called NODSEXIST via PTFs for APAR: PK83260 . Per the Comments in the APAR: The INIT command will terminate with message ICK32179I DATA SETS

Looking up the value of a symbol with ASASYMBM is a degenerate case: just give it an input pattern of: "" and the output buffer will contain the value. Kirk Wolf Dovetailed Technologies http://dovetail.com On Wed, Sep 27, 2017 at 5:28 PM, scott Ford wrote: > All: > > I

Invitation for early Friday war stories. When implementing (OS-moniker-du-jour) 1.6, we had several catastrophic failures that required back out to previous level. We took some SADs during that stormy period. When implementing z/OS 1.13, we had several instances of running clean out of real

Hmmm. It seems to me that you can check the STCBBFP flag both at save time and at restore time: * If off at save time, then don't save them, but remember that it was off. * At restore time, if STCBBFP had been off at save time, but now is on, then you know that the signal handler did,

I don't know of any SADMP PTFs that were not downward compatible within the same release of z/OS, and we would certainly try to avoid creating that scenario. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp. Poughkeepsie NY > In addition the SAD IPL volume should in principle

Re: DLIB volume for SAD

As a practical matter, the SAD IPL volume needs enough space to contain the SYS1.PAGEDUMP.Vxx data set, which seems to be 92 tracks at z/OS 2.1. Furthermore, the volume needs to be reachable--not necessarily online--from every MVS image that might conceivably need to take SAD. Depending on

The only restrictions on the SAD IPL device is that it must not contain a page data set for the system being dumped, and it must not be used as an output device for this dump. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp. Poughkeepsie NY > This is general question. > >

Re: DLIB volume for SAD

I don’t know what you mean by dlib volume. I'm assuming you mean SMP DLIB volume. It really doesn’t matter what volume you use to IPL SAD. In our shop, we write SAD ipl code to a few environment specific volumes, that direct SAD to write to a mod-54(s).
