NAME

       qmod - modify a 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 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 VARIABLES

       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.

FILES
