DFHFCLJ (file control logging and journaling program)

DFHFCLJ is the file control logging and journaling program. It is called to perform logging for transaction backout and forward recovery, to write to journals for autojournal requests and to write to the log of logs.

Records are written to the system log using the RMRE APPEND function, and optionally forced using the RMRE FORCE function. Records are written to forward recovery logs and autojournals using the LGGL WRITE function, and to the log of logs using the LGGL WRITE_JNL function.
