qterm(8)
NAME
qterm - terminate processing by a PBS batch server
SYNOPSIS
qterm [-t type] [server...]
DESCRIPTION
The qterm command terminates a PBS batch server. When a server
receives a terminate command, the server will go into a terminating
state. While in this state, the server will not allow new jobs to be
started or enqueued. By default, qterm will request a "quick" shutdown
of the PBS server. Other ways of shutting down the server (specified
with the -t argument), and their impact on running jobs, are described
below. The qterm command will not exit until the server has completed
its shutdown procedure.
In order to execute qterm, the user must have PBS Operation or Manager
privilege.
OPTIONS
- -t type Specifies the type of shut down. The types are:
- immediate
All running jobs are to immediately stop execution.If checkpoint is supported, running jobs that were submitted with "-c shutdown" are checkpointed, terminated, and requeued. If checkpoint is not supported or the job cannot be checkpointed, running jobs are requeued if the rerunable attribute is true. Otherwise, jobs are killed.Normally the server will not shutdown until there are no jobs in the running state. If the server is unable to contact the MOM of running job, the job is still listed as running. The server may be forced down by a second qterm -t immediate command.
- delay If checkpoint is supported, running jobs that were
submitted with "-c shutdown" are checkpointed, terminated, and requeued. If a job cannot be checkpointed, but can be rerun, the job is terminated and requeued. Otherwise, running jobs are allowed to continue to run. Note, the operator or administrator may use the qrerun and qdel commands to remove running jobs.
- quick This option is used when you wish that running jobs be
left running when the server shuts down. The server will cleanly shutdown and can be restarted when desired. Upon restart of the server, jobs that continue to run are shown as running; jobs that terminated during the server's absence will be placed into the exiting state.
OPERANDS
The server operand specifies which servers are to shutdown. If no
servers are given, then the default server will be terminated.
STANDARD ERROR
The qterm 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 qterm
command, the exit status will be a value of zero.
If the qterm command fails to process any operand, the command exits
with a value greater than zero.
