17.9 Checkpointing a trigger
Context
Checkpointing is the process of saving state information when Moab is shut down. In general, triggers defined in the moab.cfg file are not checkpointed but are recreated when Moab starts. The exception is the JOBCFG parameter, which attaches triggers to jobs as they are created. There are two cases in which you may want to tell Moab to checkpoint a trigger:
- If a trigger is defined in the moab.cfg file but was created at the command line
- When creating a trigger using the mschedctl command
To checkpoint a trigger
- Locate the trigger to be checkpointed in the moab.cfg file, create one on the command line, or modify a trigger dynamically (See Modifying a trigger for more information). Attach the checkpoint flag using the FLAGS attribute. For more information about flags, see Flags.
- If you are working in the configuration file, save the changes. Moab will now checkpoint your trigger.
