在Oracle 10g数据库服务器上,$ORACLE_HOME/rdbms/audit目录下,生成了大量的以aud为扩展名的文件。

查看一下日志文件内容,记录的都是以sysdba访问数据库实例ASM的操作。

这是因为:

以sysdba身份访问oracle asm 实例,,不管你打开或者关闭审计,系统都会在$ORACLE_HOME/rdbms/audit目录下记录访问日志,生成*.aud文件。

只能使用一个crontab来自动清理这些文件。

10 * * * * find /u01/app/oracle/product/10.2.0/db/rdbms/audit/ -name "*aud" -exec rm -rf {} \;

设置成每个小时清理一次。

但随后又发现新问题,清理后,日志文件增长的速度非常惊人,每秒都有几个文件生成,每个文件大小714个字节。如此多的文件,将严重影响系统IO。

无法判断出ASM实例上哪个连接出现了问题。
