The DSNDELETE command causes all expired data sets in the archives to be deleted from the DSNINDEX. If you have specified sysparm UNCATDEL with a value of Y, it also deletes all data sets in the archives that were archived to an expiration date of Julian date 1999.000 and which are no longer cataloged.
Note: If the catalog status of a data set cannot be determined because a catalog is either damaged or offline, no action will be taken.
The entire index is scanned for expired data sets. If all data sets for an archive volume are deleted through processing, the ARCHVOLS record will also be deleted and the volume will be released from the archives.
In addition, CA 1 Tape Management, EPIC, RMM, or Control-T (CTT) customers should read the section Method 1 - Controlling Tapes through the EDM in the Installation Guide.
If it is determined that no DSNINDEX records exist for a given ARCHVOLS record, a flag bit is checked to ensure that the volume has been closed. If the volume is still flagged as OPEN, it will not be deleted unless the creation date is less than today's date minus one (that is, CREDT TODAY-1). This check maintains integrity even if ARCHIVE and IXMAINT are running concurrently over midnight.
For more information, see the sysparm description for IXMCLEANy in the Systems Guide. This sysparm is used as a general cleanup tool to correct pointer errors that exist in the FILES.
