Master Controller Command Syntax |
Scroll |
Commands can be issued to the z/OS Master Controller from one or more of the following sources:
•The Operator’s console - Commands entered from the operator’s console adhere to normal z/OS conventions such as ‘P’ for STOP and ‘F’ for MODIFY. Execution of commands from the operator’s console is immediate.
•Replying to an outstanding WTOR message - In order to issue commands from an outstanding WTOR message, WTOR=Y must be specified in the startup parameter file. Execution of commands from an outstanding WTOR is immediate.
•From a IBM MQ command queue - In order to issue commands from the IBM MQ command queue, the CMDQUE keyword must contain a valid IBM MQ queue name. The SQDCOPYQ utility is used to insert commands in the command queue. A sample JCL member (MASTCMD) is supplied in the SQDATA.V4nn.CNTL library.
Note: when issuing commands through the command queue, there may be a delay of up to 30 seconds before the command is received by the z/OS Master Controller.
The following table summarizes the commands that can be issued to the Master Controller:
