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.
