Re: Problem with stacked ddr tape and possible DYNAM
No apologies needed for me. You just responded very quickly with details that can actually help a customer in need. Would that all product support respond so quickly with helpful info -- and not even through a support call! Mike Walter A (ususally) satisfied CA customer. And yes, to those amazed at that from me, I still find it hard to believe such comes from my own fingers. CA must have improved overall customer satisfaction by large measures in one "swell foop" when buying Sterling Software's VM product line. - Original Message - From: "Imler, Steven J" [EMAIL PROTECTED] Sent: 05/02/2008 10:03 PM AST To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Problem with stacked ddr tape and possible DYNAM And yes ...

Re: Problem with stacked ddr tape and possible DYNAM
Mike, In this case it has nothing to do with ATTACH MULTIUSER ... it has to do with a timing issue relative to 3590s "spacing out" ... no interrupt for 2, 3, 4, 5, 20 minutes is just fine :-( Hence we have the IBM recommendation/default for MIH for a 3590 at 12.5 minutes (or is it 20.5 minutes) ... I can't remember any more.

Les, It's because in this case the play/interaction is intiment between the end user and the DYNAMCMS server ...

Re: Problem with stacked ddr tape and possible DYNAM
It is/was a timing issue where the tape is being passed back to the DYNAMCMS server at DYNCLOSE to write trailer labels for the dataset ... then back to the end user who subsequently issues a DYNOPEN for DSN 4 on the same tape causing the tape to be passed back to the DYNAMCMS server to validate the volume ... rewind to check VOL1 followed by subsequent FSF(s) to position to the end of DSN 3, then prepare the HDR1 labels for the new 4th DSN. In any case, the timing issue caused DYNAMCMS to incorrectly state there was only one file on the tape resulting in a automatic CANCEL ... so the tape was never reattached to the end user because the DYNOPEN was cancelled. This resulted in DDR failing because there actually was no tape attached to the end user at virtual device 181. I've been waiting for another report of a failure from the customer after providing them with some trace diagnostics ... but as far as I know there hasn't been another failure (because I haven't heard anything back for over a week).

Perhaps DYNAMVM is look for the "given" message instead of waiting for the interrupt that indicates a device has appeared? (I don't know how it works.) Alan Altmark z/VM Development IBM Endicott
