Stopping local processors

Before you remove a local main for maintenance or other reasons, allow processing jobs to complete normally. Use the following steps:

1. Enter a *F, V,main,OFF command for the local main to prevent JES3 from scheduling any further jobs on the processor.
2. Enter the *RETURN command to end JES3 after all jobs on the local main have completed processing.
3. Enter the HALT EOD command on the local main to ensure that important statistics and data records in storage are not permanently lost.

Your installation may not want to wait for all jobs to complete normally. For example:

• Jobs will not end because of system problems (hardware and software)
• An IPL or JES3 restart is scheduled to take place at a predetermined time and jobs will not be able to complete. In this case, you must make the decision to delay the IPL or to cancel the jobs. (Your installation procedures should tell you whether to cancel jobs or delay an IPL.)
