qhold - hold pbs batch jobs


qhold [-h hold_list] job_identifier ...


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: (also known as operator), and

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 or an 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 described 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 described in the general section.  


-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 -
o -
s -



The qhold command accepts one or more job_identifier operands of the form:



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


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.
