Routing codes determine where a message is displayed.
More than one routing code might be assigned to the message. With
multiple-console support, each console operator receives the messages
related only to the commands entered at that console or to the functions
assigned to that console, regardless of the routing codes assigned
to those messages. If a message that is routed to a particular console
cannot be issued at that console, that message is issued at the master
console.
The following routing codes are used in IP messages:
- Code
- Meaning
- 1
- Master Console Action: This message indicates a change
in the system status and demands action by the master console operator.
- 2
- Master Console Information: This message indicates a change
in the system status. Such a message does not demand action, but alerts
the master console operator to a condition that might require action.
This routing code is used for any message that indicates job status,
and also for processor and problem program messages to the master
console operator.
- 3
- Tape Pool: This message specifies the status of a tape
unit or reel, the disposition of a tape reel, or other tape-oriented
information. For example, this can be a message which requests that
tapes be mounted.
- 4
- Direct Access Pool: This message specifies the status of
a direct access unit or pack, the disposition of a disk pack, or other
direct-access-oriented information. For example, this can be a message
which requests that disks be mounted.
- 5
- Tape Library: This message specifies the tape library information.
For example, this can be a message which requests, by volume serial
numbers, that tapes be obtained for system or programmer use.
- 6
- Disk Library: This message specifies the disk library information.
For example, this can be a message which requests, by volume serial
numbers, that disk packs be obtained for system or programmer use.
- 7
- Unit Record Pool: This message specifies the unit-record
equipment information. For example, this can be a message which requests
that printer trains be mounted.
- 8
- Teleprocessing Control: This message specifies the status
or the disposition of data communication equipment. For example, this
can be a message that indicates line errors.
- 9
- System Security: This message is associated with security
checking. For example, this can be a message that requires a reply
that is specifying a password.
- 10
- System Error Maintenance: This message indicates either
a system error, or an input/output error that cannot be corrected.
It also indicates a message that is associated with system maintenance.
- 11
- Programmer Information: This message is for the problem
programmer. This routing code is used only when the program that issued
the message cannot route the message to the programmer by using the
system-output data set facility. The message is displayed in the system
output message class of the job.
- 12
- Emulators: This message is issued by an emulator program.
