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: (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 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
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.
