 NAME
      queuedefs - queue description file for at, batch, and crontab

 SYNOPSIS
      /var/adm/cron/queuedefs

 DESCRIPTION
      The queuedefs file describes the characteristics of the queues managed
      by cron (see cron(1M)).  Each non-comment line in this file describes
      one queue.  The format of the lines are as follows:

	   q.[njobj][nicen][nwaitw]

      The fields in this line are:

	   q	     The name of the queue, such that a is the default queue
		     for jobs started by at (see at(1)), b is the queue for
		     jobs started by batch (see at(1)), and c is the queue
		     for jobs run from a crontab file (see crontab(1)).
		     Queue names d through y designate user-defined queues.

	   njob	     The maximum number of jobs that can be run
		     simultaneously in that queue.  Although any number can
		     be specified here, the total number of jobs that can be
		     run on all the queues is limited to 100.

	   nice	     The nice value to give to all jobs in that queue that
		     are not run with a user ID of super-user (see nice(1)).
		     The default value is 2.

	   nwait     The number of seconds to wait before rescheduling a job
		     that was deferred because more than njob jobs were
		     running in that job's queue, or because more than 100
		     jobs were running in all the queues (see njob above).

 EXAMPLES
      Consider the following queuedefs file:

	   a.4j1n
	   b.2j2n90w

      The file is interpreted as follows:

	   a.4j1n	  The a queue, for at jobs (see at(1)), can have up
			  to 4 jobs running simultaneously, and those jobs
			  will be run with a nice value of 1.

			  Since no nwait value is given, if a job cannot be
			  run because too many other jobs are running, cron
			  will wait 60 seconds before trying again to run it
			  (see cron(1M)).

	   b.2j2n90w	  The b queue, for batch jobs (see at(1)), can have
			  up to 2 jobs running simultaneously.	Those jobs
			  will be run with a nice value of 2.  If a job
			  cannot be run because too many other jobs are
			  running, cron will wait 90 seconds before trying
			  again to run it.

      All other queues can have up to 100 jobs running simultaneously.	They
      will be run with a nice value of 2, and if a job cannot be run because
      too many other jobs are running, cron will wait 60 seconds before
      trying again to run it.
