Spooled file subsystem

The spooled file subsystem, QSPL, is used for processing the printer writer programs and must be active when printer writer programs are active. The spooled file subsystem and the individual printer writer programs can be controlled from jobs that run in other subsystems.

The Start Printer Writer (STRPRTWTR) command submits writer jobs to the job queue of the spooled file subsystem.

Requests for writer jobs are placed on the QSPL job queue, and the next entry on the QSPL job queue is selected to run if:

  • The number of active jobs is less than the QSPL subsystem attribute of MAXJOBS.
  • The number of active jobs from the QSPL job queue is less than the MAXACT attribute for the job queue.
