XCOMREST

Records the restart information for TYPE=EXECUTE file transfers. If a file transfer fails due to a restartable condition, the XCOMREST file holds the information to restart the file transfer request from the last checkpoint. If you enter the XCOMREST DD statement in the JCL, CA XCOM Data Transport supports the restart of the TYPE=EXECUTE request.

The XCOMREST DD statement is not used with TYPE=EXECUTE transfers that have specified CONTINUE=YES. In the PARM statement, with one or more NEWXFER statements in the SYSIN01 data set. Such requests cannot be restarted in a reliable manner.

This data set is one record, a sequential file, and must not be a member of a PDS. A unique XCOMREST data set is required for each transfer. See CAI.CBXGJCL(DEFQSAM) for the sample.
