1.1. New Features of oracle11G 1.2. Audit 1.3. 1. Audit Overview

 

1) What is audit and its role?

Audit (Audit) is used to monitor database operations performed by users, and Oracle stores Audit trail results in OS files (default location: $ ORACLE_BASE/admin/$ ORACLE_SID/adump /) or database (SYS. in the AUD $ table, you can view it in dba_audit_trail.

 

In oracle11g, the audit function (AUDIT_TRAIL) is enabled by default. In earlier versions, auditing is disabled by default.

 

Because audit is enabled, the database consumes a lot. This will reduce the business performance. Therefore, if not necessary, you can choose to disable the database audit function after installing the database.
