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
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.
