While CICS® is running, it can produce several types of messages.
- Console messages advise the system operator of execution progress, or
request a decision.
- Certain CICS-supplied support programs communicate directly with terminal
operators.
- CICS management modules and support programs log significant events and
error occurrences to transient data destinations; for example, to the control
system master terminal (CSMT), or to the CICS database control log (CDBC) for the CICS-DBCTL
interface.
- The CICS message switching program (DFHMSP) generates message switching responses
(described in the CICS Supplied Transactions manual).
- CICS directs informational macro notes (mnotes) to programmers. These
are not documented.
- Messages produced by CICS utility programs such as DFH£MOLS and DFHMNDUP.
These messages are self-explanatory and are not documented.
With the exception of the AXM messages, a
small number of numeric abends and the Transaction Dump Codes, the messages
described in this book can also be viewed online using the CICS transaction
CMAC.
For guidance on using CMAC, see the CICS Supplied Transactions manual.
