DCB=(RECFM=F,BLKSIZE=1024,LRECL=1024)

Space Requirements

The amount of space that is required depends on the number of jobs that CA WA CA 7 Edition controls. The communications data set requires a minimum of 50 contiguous tracks.

DASD Restrictions

The data set must reside on a shared DASD device in multi-CPU environments.
