Change images are maintained for each data table created in the new user.

Specifying the JOURNAL keyword without also specifying either NO or DUAL implies single copy journaling.

If journaling is specified, a DUAL journal is maintained for data tables with FALLBACK protection.

The JOURNAL keyword without BEFORE implies both types (BEFORE and AFTER) of images.

NO
Change images are not maintained for each data table created in the new user.
DUAL
Dual change images are maintained by default for each data table created in the new user.
BEFORE
Number of BEFORE change images to be maintained by default for each data table created in the new user.
