Re: [EXTERNAL] Seeking help with DFSMSrmm
Erika, Simon Thank you for coming back on this. Up until the time of raising this thread, I was working with RETENTIONMETHOD(EXPDT) specified, and getting the results I described. Having sent my email, I moved on to RETENTIONMETHOD(VRSEL), but that didn't help a lot - the EXPDT specified on the DD statements I was using had no effect. So I moved back to using EXPDT and UNCATALOG(N). My RETENTIONMETHOD parameter is now: RETENTIONMETHOD(EXPDT(CATLGDAYS(0) GDG(RETPD(0) WHILECATALOG(ON)) LASTREF(0) NOGDG(RETPD(0) WHILECATALOG(ON)) NOLASTREF RETAINBY(VOLUME))) which gave results that were close to what I think should happen. With this parameter in control, If I create a tape file with EXPDT=99000 specified then delete or uncatalog the file, and run the scratch housekeeping job (EXPROC), then the tape that is used should be released, to my way of thinking. What actually happens is that the tape is tagged with an expiry date of 'today', sure, but it turns out there is also an expiry *time* to take in to account. I don't know the exact method used to calculate this time value, but it appears to be something like: 'current time plus 90 minutes, rounded to the nearest hour'. So if I create a file at 9:00 and then delete it, no amount of scratch processing will release the tape before 10:00. A file created and deleted at 9:31 means that the associated tape volume doesn't get released until 11:00. *sigh* there's got to be a way around this. (going back to the manuals...)

Re: [EXTERNAL] Seeking help with DFSMSrmm
A good source of information on the different retention method options in RMM is the DFSMSrmm Primer: http://www.redbooks.ibm.com/abstracts/sg245983.html?Open ... this IBM Redbook provides a highlight of the different functions within RMM including the different retention methods that can be used ... retention through VRS policies RETENTIONMETHOD(VRSEL) and retention through expiration RETENTIONMETHOD(EXPDT). After that you can look at Chapter 3 Retention Methods in the following RMM manual ... https://www-01.ibm.com/servers/resourcelink/svc00100.nsf/pages/zOSV2R3sc236873/$file/idarm00_v2r3.pdf for an overview of each. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: [EXTERNAL] Seeking help with DFSMSrmm
Hi Sean, Have you created VRS definitions? These are used to control retention, based on a variety of factors, such as whether the dataset is catalogued. EDGRMMxx is more to do with system options and VLPOOL defs where I guess you'd set EXPDTCHECK(N) to rely on RMM volume status to govern scratch eligibility etc. thanks, Simon. -Original Message- From: IBM Mainframe Discussion List On Behalf Of Sean Gleann Sent: 29 July 2019 08:46 To: IBM-MAIN@LISTSERV.UA.EDU Subject: [EXTERNAL] Seeking help with DFSMSrmm WARNING: this email has originated from outside of the SSE Group.
