To accommodate archival to disk, the following options are available within the following functions:
Parameter SCRATCH=YES/NO is available on the DSNDELETE, VOLDELETE, and PURGE commands. DSNDELETE and VOLDELETE default to SCRATCH=YES, which means to scratch and uncatalog the disk archive data set when the archvols record is being deleted. PURGE defaults to SCRATCH=NO, because it is frequently used just prior to running REBUILD. If a disk archive data set is scratched, there is nothing from which to rebuild. If you do not intend to follow PURGE with a REBUILD command, specify SCRATCH=YES. Otherwise, you are creating disconnected archive data sets on disk that are never used or deleted by any other means.
The following parameters have been added.
TYPE=(DISK,TAPE,3480)—specify any of the three types listed to restrict the merge to archvols of those types.
CREDT=date—only those archvols created on or before the specified date are merged forward.
DAYSOLD=dddd—an "alternative form" of the CREDT parameter that limits the merge to those archvols that were created dddd or more days ago.
Rebuild accepts the archive data set to be read as input from either tape or disk. The supplied JCL procedure requires that you provide the correct //ARCHIVES DD statement pointing at the tape or disk data set to be rebuilt. No input cards are required. If they are provided, only the expiration date parameter is used.
