Troubleshooting the AIX spooler can be done by tracking a spooler job through the spooler.
A job submitted to the AIX spooler moves from one spooler component to another in a
predictable fashion. The movement is entirely dependent upon the spooler queue
configuration, especially the spooler queue backend.
Note: To perform serious spooler troubleshooting, root authority is required. Users
running without root authority are limited to:
• Submitting jobs to the spooler
• Sending data directly to the device driver entry point in the /dev directory
• Querying the status of spooler queues
• Changing the status (including cancelling) of spooler jobs owned by the user
Note: This troubleshooting information assumes that you have access to a shell prompt.
There are a number of front–ends to the AIX spooler itself on the market; troubleshooting
in this environment is still very possible, but if the problem lies in the command or
method used to actually submit a job to the spooler, the application must provide a
method for precisely determining the command or method used to submit the job to the
spooler.
