Define Data to the DLF Record

You can allow a specific data set to be brought into hyperspace that is accessed by one of the jobs in the JOBNAME list.

To define a data set to the DLF record, enter the command:

TSS ADDTO(DLF) DSNAME(data‑set‑name)
               JOBNAME(job‑name1,job‑name2,...)

            RETAIN

DSNAME

Identifies a prefix for a data‑set‑name brought into hyperspace.

Range: 2 to 26 characters

JOBNAME

Identifies an job‑name that accesses a data set brought into hyperspace.

Range: Up to eight‑characters

RETAIN

Leaves a data set in hyperspace when the job that brought it into hyperspace ends.

Example: defining DLF record data

This example adds data set CICS.MASTER.FILE to the DLF Record and allows it to be brought into hyperspace when it is accessed by JOB1, and to remain in hyperspace after the job ends:

TSS ADDTO(DLF) DSNAME(‘CICS.MASTER.FILE’) 
               JOBNAME(JOB1)
               RETAIN
