Diagnosing Unusual Problems
If you encounter other problems with your spooler subsystem, performing a memory
dump of the supervisor process’s memory could provide information for fixing these
kinds of problems:
•
Spooler response time is inexplicably slow.
•
The job command fails to take effect (jobs hang).
•
The supervisor sends error messages continuously.
Problems such as the above are unusual, but they might occur in large installations
where development is performed. You perform the dump operation while the spooler is
running; you need not drain the spooler or stop any spooler processes before performing
this operation.
To recover from unusual problems such as those listed above, you might need to dump
the memory of the supervisor process to a disk file for analysis. Check with your
operations management before performing a supervisor memory dump to make certain
that this is the appropriate action.
To perform a memory dump of the supervisor’s memory, enter:
> SPOOLCOM
) SPOOLER, DUMP filename
where filename is the name of a disk file the spooler creates for the purpose of this
operation.
