Oracle 12c how to purge the FGA audit records before a certain date please I need to know how to purge the FGA audit records before a certain date, I have an Oracle 12c R1 database in which the audit with FGA is implemented, the tables of this are in a tablespace called ts_audit.dbf that It has already had 3 full datafiles and continues to be filled at a dizzying pace due to the intensive use of the database, for this reason I need to purge the oldest records, let's just leave those of the last week.
Thank you very much for your help.
