This information supports z/OS® Version
2 (5650-ZOS).
Purpose of this information:
This information primarily describe messages that are issued to
the system operator at the system console and system messages that
are logged. These include:
- Operator messages issued by the BCP and DFSMS/MVS.
- Log messages issued by the BCP and DFSMS/MVS.
- Some SYSOUT messages issued by the BCP and DFSMS/MVS. SYSOUT messages
are issued by utilities that normally run in batch, such as SPZAP.
- Batch job messages issued by the BCP. Messages issued by JES2
or JES3 for batch jobs are in the JES messages documents.
For the most part, messages issued at interactive terminals (like
TSO/E and CICS® terminals) are
documented by the specific elements and products that support those
terminals.
If you do not know which document describes a particular message,
try using LookAt. Here are some of the documents on that bookshelf:
This information also contains the routing and descriptor codes
that IBM® assigns to the messages
that z/OS components, subsystems,
and products issue. Routing and descriptor codes are specified by
the ROUTCDE and DESC keyword parameters on WTO and WTOR macros, which
are the primary methods that programs use to issue messages. The routing
code identifies where a message will be displayed. The descriptor
code identifies the significance of the message and the color of the
message on operator consoles with color.
Who should read this information:
The system messages documents are for all people who receive messages
from the system. Usually, these people are system operators, system
programmers, and application programmers who do any of the following
tasks:
- Initialize the operating system and its subsystems
- Monitor system activity
- Keep the system running correctly
- Diagnose and correct system problems
- Diagnose and correct errors in problem programs
Where to find the most current message information:
The MVS System Messages documents
are cumulative. As messages are added to the system they are added
to the documents. Similarly, when messages are changed on the system,
they are changed in the documents. However, when a message is deleted
from the system (no longer issued), the message is not deleted
from the document. This means that users can look in the most recent
message documents for the most current descriptions of system messages.
To find the most current edition of a document, you can look on
the Web. Point your browser to the
z/OS home page
