Graceful Shutdown

IXMAINT jobs can be shutdown gracefully by using sysparm IXMREPLY. A graceful shutdown will allow the jobs to complete all work in progress and produce the normal reports for error conditions encountered and work successfully completed before the jobs terminate. With IXMREPLY active, a message is issued to the operator at the beginning of the job and remains on the console for the duration of the job. If the operator replies, END to this message, it indicates processing is to be stopped early. When using an FDB, an inquiry is made to validate the ARCHVOL record is empty (has no DSNINDEX records) so it can be deleted even when the IXMAINT is shut down. However when using an Files Data Set, all the DSNINDEX records must be processed before being able to delete an ARCHVOL record. So, when using the shut down option for an FDS, no ARCHVOLs will be deleted.
