SET FILE/AI JOURNAL
SET FILE/AI_JOURNAL is a DCL command that marks one or more RMS files for after-image journaling. You can also specify certain characteristics of the journal with this command, including its file specification, whether it is to be created, its initial size, and its default extension quantity. The SET FILE/NOAI_JOURNAL command unmarks a file for after-image journaling. The SET FILE command is not supported for remote files. You must use the SET FILE command from the system where the file is located.
Requires read (R), write (W), and control access. Being the ownerof the file is one way to get Control access.
