Shutdown is normally issued from an online terminal. You can issue the command from a batch terminal, if necessary. Shutdown is not supported from a trailer terminal (SASSTRLR or U7SVC) or by the TSO/ISPF interface.
For online terminals, a verification process is required before shutdown can occur. After the /SHUTDOWN command is entered, CA WA CA 7 Edition is put in a shutdown status. The terminal that entered the shutdown receives a message indicating the options that are entered for the shutdown. If the displayed options are correct, press Enter for the shutdown to occur. If the options are not correct, the /SHUTDOWN command can be changed and reentered. When two /SHUTDOWN commands with the same options are entered consecutively, CA WA CA 7 Edition shuts down.
If you specified a default shutdown type in the initialization file, you can enter the /SHUTDOWN command without any parameters. The default option is selected for normal termination of CA WA CA 7 Edition.
If a batch terminal requested the shutdown, only one SHUTDOWN command is required to shut down the system.
If a console (DEVICE=CONSL) enters the /SHUTDOWN command, the operator must enter the command a second time for verification for the shutdown to occur.
While in the shutdown mode (and until Enter is pressed or two /SHUTDOWN commands with the same options are entered), other terminals entering commands receive the following message:
The terminal that entered the /SHUTDOWN command is allowed to enter certain slash (/) commands (/LOGOFF, /DISPLAY, and so on) between the "consecutive" /SHUTDOWN commands. If an invalid command is entered while CA WA CA 7 Edition is in shutdown mode, the terminal receives an error message stating that the command must be /SHUTDOWN. CA WA CA 7 Edition can be shut down without terminating ICOM when CA WA CA 7 Edition controlled jobs are still active in OS. However, if CA WA CA 7 Edition is to be down for a long time, we recommend that you stop ICOM.
