Transient journaling is performed for global temporary and volatile tables. This option only pertains to global temporary and volatile tables.

Update, insert, or delete operations on the global temporary or volatile table are logged in the transient journal. This is the default.

NO
Transient journal logging of rows is not performed, reducing the system overhead of logging.
If an error or restart occurs and the table is defined as NO LOG, then any update, insert, or delete operations on the global temporary or volatile table cannot be recovered.
If the table is defined as NO LOG, a transient journal is generated for the transaction and the content of any materialized global temporary table or volatile table is emptied when a transaction aborts.
