v User journaling is entirely under your application programs’ control. You write
records for your own purpose using EXEC CICS WRITE JOURNALNAME
commands. See “Flushing journal buffers” on page 28 for information about
CICS shutdown considerations.
v Automatic journaling means that CICS automatically writes records to a log
stream, referenced by the journal name specified in a journal model definition,
as a result of:
– Records read from or written to files. These records represent data that has
been read, or data that has been read for update, or data that has been
written, or records to indicate the completion of a write, and so on,
depending on what types of request you selected for autojournaling.
You specify that you want autojournaling for VSAM files using the
autojournaling options on the file resource definition in the CSD. For BDAM
files, you specify the options on a file entry in the file control table.
– Input or output messages from terminals accessed through VTAM.
You specify that you want terminal control autojournaling on the JOURNAL
option of the profile resource definition referenced by your transaction
definitions. These messages could be used to create audit trails.
Automatic journaling is used for user-defined purposes; for example, for an
audit trail. Automatic journaling is not used for CICS recovery purposes.
