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 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

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 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 man page and the rerun option in the man page for more information.) Additional restrictions apply for parallel and checkpointing jobs. (See the reschedule_unknown description in the 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 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
	Sun Grid Engine master host file
