Defining routing codes for a console

Most messages have one or more routing codes. The system uses these codes, decimal numbers from 1 to 128, to determine which console or consoles should receive a message. The system programmer assigns routing codes to the consoles attached to your system so that a specific message type is routed to the proper console. Table 1 lists the routing codes.

Routing codes do not appear with a message at a console; routing codes 1 through 28 do, however, appear on the system log. To determine the routing codes each console receives, use the DISPLAY CONSOLES,A command. Figure 1 shows the display that appears in response to this command.

Table 1. Message Routing Codes
Code	Definition
1	Primary operator action
2	Primary operator information
3	Tape pool
4	Direct access pool
5	Tape library
6	Disk library
7	Unit record pool
8	Teleprocessing control
9	System security
10	System error/maintenance/system programmer information
11	Programmer information
12	Emulators
13-20	Reserved for customer use
21-28	Reserved for subsystem use
29	Disaster Recovery
30-40	Reserved for IBM®
41	Information about JES3 job status
42	General information about JES2 or JES3
43-64	Reserved for JES2 or JES3
65-96	Messages associated with particular processors
97-128	Messages associated with particular devices

One way to limit the messages that arrive at a console is to assign a routing code or codes to a console. The console then receives only the messages that are appropriate.

To learn what the routing codes for a console are, enter the DISPLAY CONSOLES command. Figure 1 shows the display that appears in response to this command.

You define routing codes for a console by:

Using the VARY command:
Use operands on the VARY command to add to the existing set (AROUT operand), subtract from the existing set (DROUT), or redefine the set (ROUT).

Example:
To assign the routing codes 1, 2, 9, and 10 for a console named CON81D, enter:
```
VARY CN(CON81D),ROUT=(1,2,9,10)
```
In console services shared mode, the effect of this command lasts for the duration of the IPL; in distributed mode, the effect of the command lasts only for the duration of the console being active.
