You can define routing codes and message levels to a specific console so that the console receives the appropriate messages indicated by the routing code or message level. For MCS or SMCS consoles, you define routing codes and message levels in CONSOLxx. Your security or TSO/E administrator defines routing codes for users of extended MCS consoles.
Sometimes a message is issued without any assigned routing information. You can define default routing codes for these messages in CONSOLxx.
You can also define a group of consoles eligible to receive and display synchronous messages that bypass normal message queuing. Display of synchronous messages describes how you can define console groups for synchronous messages.
Altering some console attributes might cause messages to no longer be displayed on consoles. Messages that are not displayed on a console will still be logged in SYSLOG and/or OPERLOG, and are viewable using facilities such as SDSF.
