- Usage notes
- The REGTIMESTMP keyword is effective when FASTIC=(,FDUMP) is specified. When FASTIC=(,FDUMP) is not specified, this keyword is ignored.
- Advantage of REGTIMESTMP=SAME is that you can have the same recovery point for all target databases. Disadvantage of REGTIMESTMP=SAME is that elapsed time of the job is longer than when run with REGTIMESTMP=DIFFER. This is because (shadow) image copy creation processes start after obtaining all authorizations for the target databases, and because the databases are released after each (shadow) image copy process is complete. However, for FASTIC=(,FDUMP) process, the difference is not significant because the shadow image copies are created by FlashCopy®.
- If you specify this keyword with the Checkpoint Restart function, which is activated by the RESTART=Y keyword, only the restarted image copies will have the same time stamp values. If you want all the target databases to have the same time stamp values, you must not use the Checkpoint Restart function.
