z/OS V2R1 introduces the following enhancements for DFSMSdss:
- A RESET keyword has been added to the RESTORE FULL
and RESTORE TRACKS commands. It specifies whether the data-set-changed
indicator is reset for the data sets on the volume being restored.
You can protect the use of RESET with the RESTORE command. In addition,
you can now protect the use of RESET with the DUMP command.
- A DEBUG(SMSMSG) option has been added to the CONVERTV
command, the COPY command for logical and physical data sets and the
RESTORE command for logical and physical data sets. It instructs DFSMSdss
to include ACS WRITE statements in the job output.
- The FCCGVERIFY keyword on the CGCREATED command now accepts multiple
volume serials.
- The REPLACEUNCONDITIONAL keyword on the RESTORE
command now works for physical data sets.
- The RENAMEUNCONDITIONAL keyword on the RESTORE
command, which previously worked only on non-VSAM physical data sets,
will now work on VSAM physical data sets, as well.
- The ZCOMPRESS keyword on the DUMP command specifies
that DFSMSdss writes the dumped data in compressed format to the output
medium using zEDC Services.
The following table lists the types of tasks and associated procedures
that you must complete to fully use these enhancements.
