During processing, your installation may want to test a new system or make modifications to an existing system without disrupting the other processors or their workloads. The $T MEMBER(memname),IND= command allows you to change the operational mode of the system on which the command is entered. Specifically, you may set a member within a MAS configuration to independent mode so that it may operate independently of the configuration.

A processor designated as operating in independent mode processes only jobs that are routed to it and designated to execute on a processor in independent mode. Non-independent mode jobs that try to execute on that processor can not do so until the processor is taken out of independent mode. The spool volumes are still shared with other processors in the MAS configuration.
