Set [no]journaling Option
The set journaling|nojournaling statement sets the session default for the create statement. If you specify set journaling, tables are created with journaling unless you specify no journaling in the create statement. If you specify set nojournaling, tables are created with journaling turned off, unless you specify journaling in the create statement.
If you set journaling on an individual table, journaling for the specified table begins at the next checkpoint. For more information about checkpoints, see the Database Administrator Guide.
