ADD AUDIT Clause
Use the ADD AUDIT clause with the ALTER TABLE command to include a table in selective row-level auditing.
When you alter a table with the ADD AUDIT clause, row-level audit events in that table are recorded when selective row-level auditing is turned on. Applying the ADD AUDIT attribute to a table by itself does not enable selective row-level auditing. This type of auditing is enabled when the ADTROWS parameter of the adtcfg file is set to 1 or 2 by using the onaudit -R command.
If selective row-level auditing is not enabled, the ADD AUDIT attribute on a table has no effect.
You must have RESOURCE or DBA privileges to run ALTER TABLE command with the ADD AUDIT clause.
