Using Work Data Sets
The CA Dynam/T work data set lets you use tape as intermediate storage for a
file while processing a job, then return the tape to the scratch pool when
processing is completed.
Establish the work data set with the DYNCAT DEFINE command. Include the
WORK=YES parameter. For example, this DEFINE statement establishes a
work data set named BGWORK:
DEFINE 'BGWORK' WORK=YES TAPE
Altering Retention Characteristics
You cannot specify retention characteristics for a work data set (such as
cycles, days, or AS-OF-DATE), because a work data set is, by definition,
temporary. You can modify its retention criteria, however, with the DYNCAT
ALTER command.
