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...)
