The number of spooled files in your server should be limited. When a job is completed, spooled files and internal job control information are kept until the spooled files are printed or canceled. The number of jobs on the server and the number of spooled files known to the server increase the amount of time needed to perform IPL and internal searches, and increases the amount of temporary storage required.
Periodically identify spooled files that are no longer needed and delete them. For more information on how to display a list of spooled files, see Display a list of spooled files.
You can control the number of job logs that are generated by using the LOG parameter on the Create Job Description (CRTJOBD) or Change Job (CHGJOB) commands.
You can control the number of spooled files generated by jobs with the QLOGOUTPUT system value and LOGOUTPUT job attribute. For more information, see Work with job log pending in the Work management topic collection.
