The -JOURNAL and -REPLICATION qualifiers are the only SET qualifiers relevant for journaling. For information on the other MUPIP SET qualifiers, refer to Chapter 5: “General Database Management”.
-[NO]J[OURNAL][=journal-option-list]
Enables or disables journaling for the specified database file or region(s). MUPIP SET commands with this qualifier also establish the characteristics for journal files. FIS believes the defaults and minimum for journal file characteristics are in line with current hardware capabilities and suitable for a production environment.
The journal-option-list contains keywords separated with commas (,) enclosed in double quotes "". These double quotes are optional when the list contains only one keyword. This option list is a super set of the journal-option-list available through GDE.
-NOJOURNAL specifies that the database does not allow journaling, or disables journaling for a database that currently has it enabled. It is equivalent to -JOURNAL=DISABLE.
-NOJOURNAL does not accept an argument assignment. It does not create new journal files. When a database has been SET -NOJOURNAL, it appears to have no journaling file name or other characteristics.
-JOURNAL= enables journaling for a database file. -JOURNAL= takes one or more arguments in a journal-option-list. As long as journaling is ENABLED and turned ON at the end of the command, SET -JOURNAL= always creates a new version of the specified journal file(s).
-NOJOURNAL specifies that the database does not allow journaling, or disable journaling for a database where journaling is active.
Enable BEFORE_IMAGE or NOBEFORE_IMAGE journaling for a database file.
As long as journaling is ENABLED and turned ON at the end of the command, SET -JOURNAL= always creates a new version of the specified journal file(s).
Every MUPIP SET -JOURNAL command on a database file that specifies an ON or OFF journal-activation option causes the values of all explicitly specified journal-file-options to be stored in the database overriding any previously established characteristics for those options.
If you specify both -JOURNAL and -NOJOURNAL in the same command line, the latter takes effect.
Whenever MUPIP SET creates a new journal file, it uses all values for journal-file-options that the user explicitly specifies in the command line for the new journal file. If you do not specify a journal-file-option, MUPIP SET takes the characteristics of the existing journal file.
MUPIP SET supports qualifiers (like -ACCESS_METHOD, and so on) to change non-journaling characteristics of database file(s). If you specify these qualifiers -JOURNAL , MUPIP SET modifies the non-journaling characteristics first and then moves on to modify the journaling characteristics. Command execution stops when it encounters an error. If MUPIP SET encounters an error in processing the command line or the non-journaling characteristics, it makes no changes to any characteristics. However, if MUPIP SET encounters an error in processing the journaling characteristics, the non-journaling characteristics have already been successfully changed.
-NOJOURNAL is equivalent to -JOURNAL=DISABLE.
-NOJOURNAL does not accept an argument assignment. It does not create new journal files. When a database has been SET -NOJOURNAL, it appears to have no journaling file name or other characteristics.
For details on the journal-option-list refer to “SET -JOURNAL Options ”.
-REPLI[CATION]=replication-option
-REPLICATION sets journal characteristics and changes the replication state simultaneously. It can also be used with the -JOURNAL qualifier. If journaling is ENABLED and turned ON, SET -REPLICATION=ON creates new set of journal files, cuts the back-link to the prior generation journal files, and turns replication ON.
