Message routing codes

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.
13: Reserved for customer use.
14: Reserved for customer use.
15: Reserved for customer use.
16: Reserved for future expansion.
