queuedefs(4)						     Kernel Interfaces Manual						      queuedefs(4)

NAME

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

SYNOPSIS

DESCRIPTION

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

	      [njob[nice[nwait

       The fields in this line are:

	      q 	The name of the queue, such that is the default queue for jobs started by (see at(1)), is the queue for  jobs  started	by
			(see  at(1)),  and  is	the  queue  for jobs run from a file (see crontab(1)).	Queue names through 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,  (see
			cron(1M))  by  default limits the number of jobs that can be run on all the queues to 100.  This limitation can be removed
			by setting the variable to 1 in the file.

	      nice	The 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 file:

       The file is interpreted as follows:

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

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

	      The	     queue, for jobs (see at(1)), can have up to 2 jobs running simultaneously.  Those jobs will be run with a value of 2.
			     If a job cannot be run because too many other jobs are running, 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 value of 2, and if a job cannot be run because
       too many other jobs are running, will wait 60 seconds before trying again to run it.
