NAME

       qhold - hold back Grid Engine jobs from execution

SYNTAX

       qhold [-h {u|o|s},...]  [-help] [job/task_id_list]

       qhold [-h {u|o|s},...]  [-help] -u user_list

DESCRIPTION

       Qhold provides a means for a user/operator/manager to place so called holds on one or more
       jobs pending scheduling for execution.  As long as any type of hold is assigned to a  job,
       the job is not eligible for scheduling.

       Holds can be removed with the qrls(1) or qalter(1) command.

       There are three different types of holds:

       user   User  holds can be assigned and removed by managers, operators and the owner of the
              jobs.

       operator
              Operator holds can be assigned and removed by managers and operators.

       system System holds can be assigned and removed by managers only.

       If no hold type is specified with the -h option (see below) the user hold  is  assumed  by
       default.

       An  alternate way to assign holds to jobs is the qsub(1) or the qalter(1) command (see the
       -h option).

OPTIONS

       -h {u|o|s},...
              Assign a u(ser), o(perator) or s(system) hold, or a combination thereof, to one  or
              more jobs.

       -help  Prints a listing of all options.

       -u username,...
              Changes  are only made on those jobs which were submitted by users specified in the
              list of usernames.  Managers are allowed to use the qhold -u "*" command to  set  a
              hold for all jobs of all users.

              If a user uses the -u switch, the user may specify an additional job/task_id_list.

       job/task_id_list
              Specified by the following form:

                  job_id[.task_range][,job_id[.task_range],...]

              If present, the task_range restricts the effect of the qhold operation to the array
              job task range specified as suffix to the job id (see the -t option to qsub(1)  for
              further details on array jobs).

              The  task range specifier has the form n[-m[:s]]. The range may be a single number,
              a  simple range  of the form n-m or a range with a step size s.

              Instead of job/task_id_list it is possible to use the keyword 'all' to  modify  the
              hold state for all jobs of the current user.

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 qhold 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.
