The EXPIREBV command ends as planned when the key of the next record
is higher than the planned ending key. Because the planned ending
key was reached, a blank key value is saved in the backup control
record (BCR) as the last processed key and the planned ending key.
The key of the last MCB record processed is saved periodically
in the backup control record for this host when the host is processing
an EXPIREBV command. This saved last-processed key is used to enable
RESUME processing across system outages. If the EXPIREBV command ends
early, the key of the last MCB record processed is saved in the backup
control record for the host before processing ends. This allows processing
to begin at that key if RESUME is specified on the next EXPIREBV command
that is issued in that host. The EXPIREBV command can be caused to
end early by:
- A HOLD command with the ALL or EXPIREBV parameters. (A RELEASE
EXPIREBV or RELEASE ALL command must be issued before another EXPIREBV
command can be issued.)
- A SETSYS command with the NOBACKUP or EMERGENCY parameters.
- The STOP command.
