Understanding message routing

CONSOLxx defines console attributes to control the types of commands operators can issue and routing information for messages. The recommendations in this topic apply when specifying the CONSOLxx parmlib member in a sysplex environment.

The CONSOLE statement of CONSOLxx contains the following:

CMDSYS(*) — To direct commands issued on the console to the system on which the console is attached. Specifying CMDSYS(*) defines command association between a console and a system in the sysplex.
MSCOPE(*ALL) — To indicate that messages issued by all systems in the sysplex can be received by the console.
DEVNUM(SYSCONS) — To define the system console. The system console is used as a backup for recovery purposes and can also be used to IPL a system or, if necessary, to run the sysplex.
