- Displays the status of the most recent checkpoint
The CHKMSG command determines the status of the most recent checkpoint and displays a message on the terminal informing the user of the date and time that the checkpoint was completed. It also provides checkpoint information such as specifying the user whose procedure caused the checkpoint to timeout or is locking a required resource.
Also, any outstanding transaction is ended and the
USE=IGNORE attribute applies to the command.
Returning the checkpoint status
Output from the CHKMSG command can include status information about an extended quiesce; for example:
CHECKPOINT COMPLETED ON 01.297 13:18:44.15 SYSTEM ENTERED EXTENDED QUIESCE AT: 10/24/01 13:18:44, SYSTEM EXITED EXTENDED QUIESCE AT: 10/24/01 13:18:55, REASON = END COMMAND ISSUED BY USER NUMBER: 3
