ncmgr stop

Shut down an Accelerator queue.


vncmgr: Usage Message

        DESCRIPTION:
        Shut down a Accelerator queue.

        Acts on the queue named 'vnc', unless -queue is used
        Automatic failover is disabled, unless the -failover option is used.

        If you wish to just stop the vovserver to change the binary,
        use the -freeze option.  This keeps the vovtaskers running
        and preserves the running jobs.

        If -freeze is not used the vovtaskers are stopped, and running jobs
        will be lost.

        -writeprdir <dirname> Writes the pr file to the specified directory
        (e.g., /tmp/abc123). The directory is created if it doesn't exist.

        USAGE:
        % ncmgr [-q queue] stop [options]

        OPTIONS:
        -queue        Specify name of queue to stop; default is $NC_QUEUE if
                      set, and otherwise vnc.
        -force        Do not prompt for confirmation.
        -failover     Test the failover.
        -freeze       Freeze existing running jobs.
        -freeze_nocpr Freeze existing running jobs, no pr file compression
        -verbose      Increase verbosity.
        -writeprdir   Writes the pr file to the specified directory

        EXAMPLES:
        % ncmgr stop
        % ncmgr stop -freeze
        % ncmgr stop -freeze_nocpr
