QMOD(1)
NAME
qmod - modify a Sun Grid Engine queue and running job
SYNTAX
qmod [ options ] [ wc_job_range_list | wc_queue_list ]
DESCRIPTION
Qmod enables users classified as owners (see queue_conf(5) for details) of a workstation to modify the state of Sun Grid Engine queues for his/her machine as well as the state of his/her own jobs. A manager/operator or root can execute qmod for any queue and job in a cluster but only from administrative hosts. Find additional information concerning wc_queue_list and wc_job_list in sge_types(1).
OPTIONS
- -c Note: Deprecated, may be removed in future release. Please use
- the -cj or -cq switch instead.
Clears the error state of the specified jobs(s)/queue(s). - -cj Clears the error state of the specified jobs(s).
- -cq Clears the error state of the specified queue(s).
- -d Disables the queue(s), i.e. no further jobs are dispatched to
- disabled queues while jobs already executing in these queues are allowed to finish.
- -e Enables the queue(s).
- -f Force the modification action for the queue despite the apparent
- current state of the queue. For example if a queue appears to be suspended but the job execution seems to be continuing the manager/operator can force a suspend operation which will send a SIGSTOP to the jobs. In any case, the queue or job status will be set even if the sge_execd(8) controlling the queues/jobs cannot be reached. Requires manager/operator privileges.
- -help Prints a listing of all options.
- -r Note: Deprecated, may be removed in future release. Please use
- the -rj or -rq switch instead.
If applied to queues, reschedules all jobs currently running in this queue. If applied to running jobs, reschedules the jobs. Requires root or manager privileges. In order for a job to be rescheduled, it or the queue in which it is executing must have the rerun flag activated. (See -r option in the qsub(1) man page and the rerun option in the queue_conf(5) man page for more information.) Additional restrictions apply for parallel and checkpointing jobs. (See the reschedule_unknown description in the sge_conf(5) man page for details). - -rj If applied to running jobs, reschedules the jobs. Requires root
- or manager privileges.
- -rq If applied to queues, reschedules all jobs currently running in
- this queue. Requires root or manager privileges.
- -s Note: Deprecated, may be removed in future release. Please use
- the -sj or -sq switch instead.
If applied to queues, suspends the queues and any jobs which might be active. If applied to running jobs, suspends the jobs. - -sj If applied to running jobs, suspends the jobs. If a job is both
- suspended explicitly and via suspension of its queue, a following unsuspend of the queue will not release the suspension state on the job.
- -sq If applied to queues, suspends the queues and any jobs which
- might be active.
- -us Note: Deprecated, may be removed in future release. Please use
- the -usj or -usq switch instead.
If applied to queues, unsuspends the queues and any jobs which might be active. If applied to jobs, unsuspends the jobs. - -usj If applied to jobs, unsuspends the jobs. If a job is both sus
- pended explicitly and via suspension of its queue, a following unsuspend of the queue will not release the suspension state on the job.
- -usq If applied to queues, unsuspends the queues and any jobs which
- might be active.
ENVIRONMENTAL VARIABLES
- SGE_ROOT Specifies the location of the Sun Grid Engine standard
- configuration files.
- SGE_CELL If set, specifies the default Sun Grid Engine cell. To
- address a Sun Grid Engine cell qmod uses (in the order
of precedence):
The name of the cell specified in the environment variable SGE_CELL, if it is set.The name of the default cell, i.e. default. - SGE_DEBUG_LEVEL
- If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug information is generated is defined.
- SGE_QMASTER_PORT
- If set, specifies the tcp port on which sge_qmaster(8) is expected to listen for communication requests. Most installations will use a services map entry for the service "sge_qmaster" instead to define that port.
FILES
- <sge_root>/<cell>/common/act_qmaster
