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 run-
ning 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 simultane-
ously. 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.
