Using MCS consoles to control your JES3 installation

You can use MCS consoles to control your entire JES3 installation. If your installation requires you to log on to an MCS console before you can enter commands, you will receive a message prompting you to do so. The CONSOLxx parmlib member specifies whether a logon is required or optional. See z/OS MVS Initialization and Tuning Reference for information about CONSOLxx.

JES3 may be operated from any console that is attached to any system in the sysplex. From any console, an operator can direct a command to any system and receive the response to that command. In addition, any console can be set up to receive messages from all systems, or a subset of the systems in the sysplex. Thus, there is no need to station operators at consoles attached to each processor in the sysplex.
