-------SNIP-------------------- Suggestion: 1. It depends on PS datasets, IMO. If you do MOD then do not release space. If mod is not used then sure why not release space (for ps). I was at a shop that was infamous for being tight with the $$ and we ran a release job everynight after production bacups were done. We did not allow MOD period. 2. During the mass release everynight we also released extents. We did this using DMS. It did a credible job for releasing space. We were in the middle of replacing DMS with DFHSM and we had decided to run DFDSS to release the space instead of keeping DMS around. We did have issues with how DFDSS worked. DMS just spit out an error message and continued on but DFDSS stopped and wait until it could get exclusive control of the dataset. I honestly do not remember the space we got back but it wasn't all that much IIRC. Maybe a half 3380-3 pack out of say 20 mod 3's . DMS did have a report mode that was fairly acurate as to numbers. We also had standards that all space requests had to specify rlse. We also had pretty tight control on our DASD (production wise), test was scrutinized by other criteria and was reasonably stable. VSAM was a ball of wax. We did not have a way on reporting VSAM (if memory serves me). At another shop I was at the DASD was a mess. I was called in and found 40 volumes that were there but not being used and I cleaned it up and I got yelled at by several managers. I welcomed the chance to go into the meeting to have the manager talk to my manager and she backed up everything I did. I just archived (with DFHSM) all the old datasets. The data was there for recall. Although I did find a VSAM data set that was empty and it spanned 5 volumes and haddn't been referenced in many many months. I archived it and clipped the volumes and out them in another pool. That was a scream fest as well. My boss loved these arguments as she liked to play the hard nose.
