通过标准审计收集的额外信息包括：

• 系统更改号(SCN)，记录对系统的每一项更改。

• 用户执行的确切SQL 文本及与SQL 文本一起使用的绑定变量。只有已指定AUDIT_TRAIL=DB, EXTENDED的情况下，这些列才会出现。

Performs all actions of AUDIT_TRAIL=db, and also populates the SQL bind and SQL text CLOB-type columns of the SYS.AUD$ table, when available. These two columns are populated only when this parameter is specified.
