Symptoms

 

NOTE: In database archiving for a table adds an invisible column ORA_ARCHIVE_STATE table which controls if the row can be retrieved or not during SELECT or DML(s). This allows records to be archived versus deleted and remain in the table to be restored at a later date if needed. As a side effect, there is potential for plan and performance changes to queries accessing these tables.
