Turn off supplemental logging at database level and turn on
supplemental logging at table level.
Note: You can switch
between supplemental logging at database level and table level at any point in time.
However, you must not turn off supplemental logging at database level before you
turn on supplemental logging at table level because it takes some amount of time for
switching. During this period, Oracle does not write the PK and UI columns to the
redo log file, until the supplemental logging at table level is turned on. This can
cause Replication Agent to go to the Replication Down state.
