1.1. oracle11g new feature 1.2.   Audit 1.3.1. Audit Introduction

1) What is audit and role

Auditing (Audit) is used to monitor database operations performed by users, and ORACLE stores audit trail results to OS files (the default location is $ORACLE _base/admin/$ORACLE _sid/adump /) or database (SYS stored in the system table Space .) aud$ table, viewable through view dba_audit_trail ).

In oracle11g , the audit function (audit_trail) is turned on by default. In previous versions, auditing was turned off by default.

Because the audit is turned on, the database adds a lot of consumption. Can degrade business performance, so if it is not necessary, after you have installed the database, you can choose to turn off the database auditing feature.
