qhold(1B)			      PBS			     qhold(1B)

NAME
       qhold - hold pbs	batch jobs

SYNOPSIS
       qhold [-h hold_list] [-t	array_range] 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, OTHER (also known	as operator), and SYS-
       TEM.

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

       If no -h	option is given, the USER hold will be applied to the jobs de-
       scribed by the job_identifier operand list.

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

       If the job is in	running	state, then the	following additional 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 Hold Job batch	request	to the server  as  de-
       scribed in the general section.

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

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

		      u	- USER

		      o	- OTHER

		      s	- SYSTEM

       -t array_range The  array_range argument	is an integer id or a range of
		      integers.	Multiple ids or	id ranges can be combined in a
		      comma   delimted	 list.	 Examples:   -t	 1-100	or  -t
		      1,10,50-100

		      If an array range	isn't specified, the command tries  to
		      operate on the entire array. The command acts on the ar-
		      ray (or specified	range of the array) just as  it	 would
		      on an individual job.

OPERANDS
       The  qhold  command  accepts one	or more	job_identifier 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 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.
