CICS® writes journal data to journals or logs on log streams managed by the MVS™ system logger, or to SMF. You must define JOURNALMODELs so that the connection between the journal name, or identifier, and the log stream, or SMF log, can be made. You can use RDO, DFHCSDUP, or an EXEC CICS CREATE JOURNALMODEL command to define a journalmodel.
CICS resolves the link between the log stream and the journal request by using user-defined JOURNALMODELs or, in the situation where an appropriate JOURNALMODEL does not exist, by using default names created by resolving symbolic names. See JOURNALMODEL definition attributes for more information about this.
Journals are not user-definable resources.
