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 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.

Files

<sge_root>/<cell>/common/act_qmaster
