Defining message levels for a console

Assigning routing codes is one way to limit message traffic to a console. You can further reduce the number of messages that appear on a console by directing certain messages to consoles by message levels. The system differentiates among these kinds of message levels:
  • Write-to-operator with reply (WTOR) messages, which demand an immediate reply.
  • System failure and immediate action messages (descriptor codes 1 and 2), which indicate that a task is awaiting your action.
  • Critical eventual action messages (descriptor code 11), which indicate a potential system problem.
  • Eventual action messages (descriptor code 3), which do not require immediate attention.
  • Broadcast messages, which are normally sent to every active console regardless of the routing code you assigned to the console.
  • Informational messages, which generally indicate system status. (Most messages are informational.)
Assignment by message level means that a console can accept combinations of action, broadcast, and informational messages that the system sends to a console. You can choose among the following message level options:
R
Write to operator (WTOR) messages are to appear
I
Immediate action messages (descriptor codes 1 and 2) are to appear
CE
Critical eventual action messages (descriptor code 11) are to appear
E
Eventual action messages (descriptor code 3) are to appear
IN
Informational messages are to appear
NB
Broadcast messages are not to appear
ALL
All messages, including broadcast messages, are to appear.

If the LEVEL parameter in the CONSOLxx member is not coded, the system sends all messages, including broadcast messages, to the console.

To display the routing codes and message levels for a console, issue the DISPLAY CONSOLES command. Figure 1 shows the display that appears in response to this command.

To display the routing codes and message levels that appear only on the system log and not on any console, issue the DISPLAY CONSOLES,HC command.

You define the level of messages for a console by:
  • Using the CONTROL Command:

    Use the LEVEL operand on the CONTROL V command to assign message levels to a console.

    Example 1:

    To direct only WTOR messages and immediate action messages to the console with console name CON06, enter:
    CONTROL V,LEVEL=(R,I),L=CON06

    Example 2:

    To assign to the console with console name CON12 (and device number 81D) the informational messages directed to the tape libraries (routing code 5) and disk libraries (routing code 6), enter:
    VARY 81D,CONSOLE,ROUT=(5,6)
    CONTROL V,LEVEL=IN,L=CON12
