DUMPCLASS(RECOVERRESET): Specifying whether to reset the data-set-changed indicator in the VTOC entry
Explanation: RECOVERRESET is an optional parameter specifying whether or not the data-set-changed indicator in the VTOC entry should be reset for all data sets that are restored during full volume recover processing.
| Subparameter | Explanation |
|---|---|
| RECOVERRESET(YES) | DUMPCLASS(RECOVERRESET(YES)) When YES is specified, the data-set-changed indicator in the VTOC (DS1DSCHA) is reset (set to OFF) for all data sets on the volume being recovered. |
| RECOVERRESET(NO) | DUMPCLASS(RECOVERRESET(NO)) When NO is specified, the data-set-changed indicator in the VTOC is not reset for any of the data sets on the volume being recovered. This action indicates that the data-set-changed setting retains the value the data sets had the dump was created. |
| RECOVERRESET(DUMP) | DUMPCLASS(RECOVERRESET(DUMP)) When DUMP is specified, and the RESET keyword was specified in the dump class at the time the dump was created, the data-set-changed indicator in the VTOC is reset for all data on the volume being recovered. If RESET was not specified, or NORESET was specified, or the dump copy was created prior to z/OS V2R1 DFSMShsm, then the data-set-changed indicator is not reset and retains the value it had when the dump copy was created. Note that this parameter is not applicable for FRRECOV (fast replication recovery) because RESET cannot be specified in dump classes associated with the FRBACKUP function. For dump classes used during FRRECOV processing, specify either YES or NO. |
Defaults: When RECOVERRESET is not specified and was not previously set in the existing dump class definition, YES is used by default.
