Restart

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

Note:
Time stamping is performed on most control program output messages. Where applicable, hh.mm.ss indicates time in hours, minutes, and seconds. However, you should realize that the software clocks are not running until the system is cycled above 1052 state. As a result, the time stamp of some messages is the same as the time that the software clocks were last active.

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.
