CONNECT TO THE DATABASE AS USER SYS

3. Connect to the database as user SYS. This is necessary, as this step involves

restarting the instance. Set the audit trail destination to DB and enable

auditing of privileged users, and bounce the instance. Using SQL*Plus:

alter system set audit_trail='DB_EXTENDED' scope=spfile;alter system set audit_sys_operations=true scope =spfile;startup force;

Using Database Control, a possible navigation path from the database home

page is to take the Server tab, and then the Audit Settings link in the Security

section. Clicking the link labeled Audit Trail in the Configuration section will

take you to a window where you can modify the parameter settings in the

spfile. Alternatively, go directly to the Initialization Parameters window from

the Server tab by taking the Initialization Parameters link in the Database

Configuration section.

Set the two parameters in the spfile, and then from the database home page

shut down and restart the database.
