Checking if auditing is enabled in Oracle.

To confirm if the audit feature of the Oracle database is enabled, you can follow these steps: 1. Log in to the Oracle database as a user with sysdba privileges. 2. Run the following query to check if the audit is already enabled:

  SELECT value FROM v$parameter WHERE name = 'audit_trail';

If the result is ‘NONE’, it means that the auditing feature is not enabled; if the result is ‘DB’, it means that the auditing feature is already enabled. If the auditing feature is not enabled, you can execute the following statement to enable it.

  ALTER SYSTEM SET audit_trail='DB' SCOPE=SPFILE;

Then restart the database for the changes to take effect. Please note that viewing and modifying audit settings require sysdba privileges.
