DISABLE

DISABLE is functionally equivalent to the -NOJOURNAL qualifier of MUPIP SET. It specifies that journaling is not an option for the region or file named. If DISABLE is specified, no other options are allowed in the journal-option-list.

ENABLE

ENABLE specifies that the database file or region is available for journaling. By default, specifying ENABLE also turns journaling ON unless OFF is specified in the same option list, you must also specify BEFORE_IMAGES or NOBEFORE_IMAGES.

OFF

OFF specifies that GT.M cease recording subsequent updates to the database in the journal file. OFF may also be used to establish journaling characteristics without creating a journal file or starting journaling. When a database has been SET -JOURNAL=OFF, it has established journal characteristics ready to turn ON, but GT.M does not write journal updates to that file.

ON

ON instructs MUPIP to create a new journal file and GT.M to record subsequent database updates in that journal file. A SET -JOURNAL=ON must include either BEFORE_IMAGES or NOBEFORE_IMAGES in the accompanying journal-option-list.

Note that ON can be specified only for a file or region with journaling already ENABLE'd, or, if ENABLE is specified at the same time. ON is ignored if journaling is currently DISABLE'd for the database.

Example:

MUPIP SET -JOURNAL="ON,BEFORE_IMAGES" -REGION "*"

This command turns journaling on only for the regions with journaling already ENABLE'd.
