queuedefs - Queue description file for at, batch, and cron commands
DESCRIPTION
The queuedefs file describes the characteristics of the queues managed by cron or specifies other characteristics for cron. Each noncom-
ment line in this file describes either one queue or a cron characteristic. Each uncommented line should be in one of the following for-
mats.
q.[njobj][nicen][nwaitw] max_jobs=mjobs log=lcode
The fields in these lines are as follows: The name of the queue. Defined queues are as follows: The default queue for jobs started by at
The default queue for jobs started by batch The default queue for jobs run from a crontab file
Queues d to z are also available for local use. The maximum number of jobs that can be run simultaneously in the queue; if more
than njob jobs are ready to run, only the first njob jobs will be run. The others will be initiated as currently running jobs ter-
minate. The nice(1) value to give to all jobs in the queue that are not run with a user ID of superuser. The number of seconds to
wait before rescheduling a job that was deferred because more than njob jobs were running in that queue, or because the system-wide
limit of jobs executing (max_jobs) has been reached. The maximum number of active jobs from all queues that may run at any one
time. The default is 25 jobs. Logging level of messages sent to a log file. The default is 4. Defined levels are as follows:
level-code level
0 None
1 Low
2 Medium
3 High
4 Full
Lines beginning with # are comments, and are ignored.
EXAMPLES
The following file specifies that the b queue, for batch jobs, can have up to 50 jobs running simultaneously; that those jobs will be run
with a nice value of 20. If a job cannot be run because too many other jobs are running, cron will wait 60 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. If a job cannot be run
because too many other jobs are running cron will wait 60 seconds before trying again to run it. b.50j20n60w
The following file specifies that a total of 25 active jobs will be allowed by cron over all the queues at any one time, and cron will log
all messages to the log file. The last two lines are comments that are ignored. max_jobs=25 log=4 # This is a comment # And so is this
