The CANCEL command options
You can use the CANCEL command to request an automatic restart.
Specify the following parameter:
- RESTART={NO∨YES}
- Terminate the server immediately, specifying whether or not automatic
restart should be requested. The default is RESTART=NO.
If the server encounters an unrecoverable problem with the coupling facility connection, consisting either of lost connectivity or a structure failure, it cancels itself using the CANCEL RESTART=YES command. This terminates the existing connection and shuts down the server. A new instance of the server job is then started.
A server can also be restarted explicitly using either the server command CANCEL RESTART=YES or the MVS command CANCEL jobname,ARMRESTART.
You can also enter RESTART on its own for RESTART=YES, NORESTART for RESTART=NO.
