Terminate processing by a PBS batch server.

Synopsis

qterm [-t type] [server...]

Description

The qterm command terminates a batch server. When a server receives a terminate command, the server will go into the "Terminating" state. No new jobs will be allowed to be started into execution nor enqueued into the server. The impact on jobs currently being run by the server depends

In order to execute qterm, the user must have PBS Operation or Manager privileges.

Options

Option	Name	Decription
-t	type	Specifies the type of shut down. The types are: immediate – All running jobs are to immediately stop execution. If checkpointing is supported, running jobs that can be checkpointed 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. delay – If checkpointing is supported, running jobs that can be checkpointed 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 is the default action if the -t option is not specified. 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.
