Syntax

EOJ

Usage notes

The EOJ command signals an end-of-job condition and begins the process of Model 204 termination. It should be used in conjunction with the BUMP command. Any users, who are still active when EOJ is issued, are forced off Model 204. If files are being updated at this time, their integrity might be damaged. You can issue an EOJ command from the terminal or include it at the end of User 0's input stream. If EOJ is omitted from this stream, a user restart is invoked and the return code is set to 6.

If you enter an EOJ command from a terminal, you must confirm the command before it is executed. In response to the EOJ command, Model 204 queries:

*** M204.1076: DO YOU REALLY WANT TO END THE RUN?

If the system manager's response is Y, Model 204 is terminated. If the system manager's response is N, the EOJ command is ignored. The default response is Y if the system manager's PROMPT parameter includes the 16 option. If the RESTART command (ROLL BACK or ROLL FORWARD) is executing when the EOJ command is entered, the following message is displayed prior to the request for confirmation:

*** M204.1453: RESTART RECOVERY IS RUNNING

No confirmation is requested when the EOJ command is supplied by User 0, either in the CCAIN input stream or from the console in a single-user z/VM run.

If checkpoint logging is enabled in the Model 204 run, the EOJ command requests that a checkpoint be performed before Model 204 termination processing begins. This checkpoint request waits until the values of the CPTO and CPTQ parameters are exceeded. If updating users are finished, their work is captured by the checkpoint, otherwise it might be lost. After the checkpoint is taken or times out, termination processing proceeds.

When Model 204 processes EOJ, it abruptly ends all update units in progress and does not invoke transaction backout.
