QMOD

NAME

qmod − modify a Sun Grid Engine queue

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. 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 suspended 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.
