User journaling function
There is one XPI user journaling function, which is the DFHJCJCX call
WRITE_JOURNAL_DATA.
DFHJCJCX calls cannot be used in any exit program invoked from any global
user exit point in the:
v Statistics domain
v Monitor domain
v Dump domain
v Dispatcher domain
v Transient data program.
The WRITE_JOURNAL_DATA call
WRITE_JOURNAL_DATA writes a single journal record to the journal specified in
the journal model definition that matches the journal name (either a journal on an
MVS system logger log stream, an SMF data set, or no record is written where
DUMMY is defined in the definition).
