Someone had asked about making VMTAPE and ADSM live in peace and harmony.
 I've defined a separate scratch pool in VMTAPE and assigned the server
 userid to that pool in SCRPOOL ASSIGN.

 This is the DSMMOUNT exit I use:

 /***********************************************************************
 * ADSTAR Distributed Storage Manager                                   *
 * User tape mount exit                                                 *
 * 09/13/93 DEB Derived from IBM example and Chris Martin's WDSF mount  *
 *              exit code. Kudos to chrism AT rice DOT edu.                    *

 Push 'CP LOGOFF'
 Exit 0


 You'll also need to grant DSMEXIT* (or whatever you call your mount workers)
 MOUNTFOR and SAVEFOR authority in the VMTAPE config file. I'm still tinkering
 with the DSMDELETE exit -- I'm not quite satisfied with how the semantics work
 when it's called, but I'll post it when I think it's house-trained enough to
 go visiting.
