JES2 provides commands you can use to control your multi-access spool configuration. You can place a member in independent mode to process jobs separately from other members. Displaying the status and settings of members in the MAS configuration enables you to change specifications to modify job execution.

You can specify the processing characteristics of MAS members and control the JES2 checkpointing mechanism, which enables you to restart or duplicate processing. JES2 allows you to reset the checkpoint lock if a member in the MAS configuration should fail while holding the lock. Additionally, you can make the failed member's jobs eligible for restart on other members.

This describes the commands you use to perform these functions to control your MAS environment.
