The control program can be restarted by performing a hardware IPL or by
issuing the ZRIPL command. Whenever you restart the control program, an
initial copy of the control program is loaded from file to main
storage. The keypoint records are then loaded from the IPLed file and
are used to initialize various fields and tables in main storage. All
working storage is initialized with all main storage blocks on the uncommitted
storage lists. During initialization, a check is performed to determine
whether a dump tape is mounted and ready. If one is not mounted, you
are notified and no more action occurs until the you mount a tape. When
initialization is completed, the following message is displayed on the system
console:
CVRN0004I hh.mm.ss RESTART COMPLETED- 1052 STATE
At this point, the system accepts input only from the system console or local 3270 terminals. You can perform functions such as modifying polling status, mounting tapes, setting time, and modifying file records.
