qmod1

Usage

Overview

Qmod enables users classified as owners (see queue_conf(5) for details) of a workstation to modify the state of Grid Engine queues for their machine as well as the state of their 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(5).

Options

-c

--clear

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

--clearjob

Clears the error state of the specified jobs(s).

-cq

--clearqueue

Clears the error state of the specified queue(s).

-d

--disable

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

--enable

Enables the queue(s).

-f

--force

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 on 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

--help

Prints a listing of all options.

-r

--reschedule

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

--reschedulejob

If applied to running jobs, reschedules the jobs. Requires root or manager privileges.

-rq

--reschedulequeue

Reschedules all jobs currently running in the specified queues. Requires root or manager privileges.

-s

--suspend

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 in them. If applied to running jobs, suspends the jobs.

-sj

--suspendjob

If applied to running jobs, suspends the jobs. If a job is both suspended explicitly and via suspension of its queue, a subsequent unsuspend of the queue will not release the suspension state on the job.

-sq

--suspendqueue

Suspends the specified queues and any jobs which might be active in them.

-us

--unsuspend

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 in them. If applied to jobs, unsuspends the jobs.

-usj

--unsuspendjob

Unsuspends the specified jobs. If a job is both suspended explicitly and via suspension of its queue, a subsequent unsuspend of the queue will not release the suspension state on the job.

-usq

--unsuspendqueue

Unsuspends the specified queues and any jobs which might be active in them.

Environment

SGE_ROOT

Specifies the location of the Grid Engine standard configuration files.

SGE_CELL

If set, specifies the default Grid Engine cell. To address a 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.
