     NAME
           qhold  -  hold pbs batch jobs

     SYNOPSIS
           qhold [-h hold_list] job_identifier ...  

     DESCRIPTION
       The qhold command requests that a server place one or more
       holds on a job.  A job that has a hold is not eligible for
       execution. There are three supported holds:  user,  admin,
       (also known as operator), and system.

       A  user  may  place a hold upon any job the user owns.  An
       "operator", who is a user with "operator  privilege,"  may
       place  ether an user  or an  operator hold on any job. The
       batch administrator may place any hold on any job.

       If no option is given, the USER hold will  be  applied  to
       the jobs described by the operand list.

       If  the job identified by is in the queued, held, or wait-
       ing states, then all that occurs is that the hold type  is
       added  to the job.  The job is then placed into heldstate
       if it resides in an execution queue.

       If the job is in running state, then the  following  addi-
       tional  action  is taken to interrupt the execution of the
       job.  If checkpoint / restart is  supported  by  the  host
       system,  requesting a hold on a running job will (1) cause
       the job to be checkpointed, (2) the resources assigned  to
       the job will be released, and (3) the job is placed in the
       held state in the execution queue.

       If checkpoint / restart is not supported, qhold will  only
       set  the  the requested hold attribute.  This will have no
       effect unless the job is rerun with the qrerun command.

       The qhold command sends a HoldJob batch  request  to  the
       server as described in the general section.

     OPTIONS

       -h hold_list  Defines  the types of holds to be placed on
                     the job.

                     The  argument is a string consisting of  one
                     or  more  of the letters "u", "o", or "s" in
                     any  combination or the character "n".   The
                     hold  type associated with each letter is:

                      u - user

                      o - operator

                      s - system

                      n - none

     OPERANDS 

       The  qhold  command  accepts  one  or more operands of the
       form:
                sequence_number[.server_name][@server]

     STANDARD ERROR 

       The qhold command  will  write  a  diagnostic  message  to
       standard error for each error occurrence. 

     EXIT STATUS 

       Upon successful processing of all the operands presented to
       the the  qhold command, the exit status will be  a value of
       zero.  If the qhold  command  fails to process any operand,
       the command exits with a value greater than  zero.
