Temporarily Suspending Jobs
Temporarily Suspending Jobs
It is advisable to suspend the execution of all jobs while a STORE is being performed. (If a
job step attempts to open a file for write access which is being stored, the open fails, with
possible negative consequences for the job.)
NOTE
Advise users not to schedule jobs during the time schedule for backups.
STORE does not copy files opened by suspended jobs. Therefore, a backup
undertaken with suspended jobs may be incomplete.
To check whether there are any jobs running on the system, enter:
:SHOWJOB JOB=@J
If you see a message stating NO SUCH JOBS, or if the list contains no executing jobs (check
the STATE column for EXEC), skip to the "Send Another Warning" step below. If any jobs
are in the EXEC state, you should temporarily stop them. To do so, use the job numbers
that appear in the first column on your screen with the BREAKJOB command, as follows:
:BREAKJOB #Jnnn
Repeat the BREAKJOB command for each executing job in the list. When you have
suspended all executing jobs, check their status by entering:
:SHOWJOB JOB=@J
Each job should now be listed as SUSP, or suspended. However, jobs that have resources
allocated to them do not suspend immediately; you may have to wait for them to suspend.
NOTE
For an online backup, suspend all active jobs until you receive the message on
the console telling you that files can now be modified. At that point, you can
resume any jobs that you suspended before the backup starts.
For a 7x24 true-online backup, you do not need to suspend any active jobs
before starting the backup. They can continue to run throughout the backup.
