环境： Linux 6.4 + Oracle 10.2.0.4

1. Oracle 10g 审计功能
2. 对数据库监听器的关闭和启动设置密码

1. Oracle 10g 审计功能

Oracle 10g审计功能默认是关闭的。需要注意开启审计功能必然会额外消耗一部分数据库性能，开启审计需要重启数据库生效。具体的审计策略则需要根据项目实际要求自行配置。

1.1 查看audit相关参数

--查看audit相关参数
set linesize 200
show parameter audit
--结果如下
NAME                                 TYPE                             VALUE
------------------------------------ -------------------------------- ------------------------------
audit_file_dest                      string                           /opt/app/oracle/admin/vas/adum
                                                                      p
audit_sys_operations                 boolean                          FALSE
audit_syslog_level                   string
audit_trail                          string                           NONE

1.2 开启审计

--开启审计
alter system set audit_sys_operations=TRUE scope=spfile;
alter system set audit_trail=db,extended scope=spfile;
--重启库生效
shutdown immediate
startup
--最后再次查看确定审计已开启
SQL> show parameter audit

------------------------------------ -------------------------------- ------------------------------
audit_file_dest                      string                           /opt/app/oracle/admin/vas/adum
                                                                      p
audit_sys_operations                 boolean                          TRUE

audit_trail                          string                           DB, EXTENDED

1.3 配置审计策略

--查看审计策略
select * from DBA_STMT_AUDIT_OPTS; 

--配置审计策略（参考11g默认开启的审计选项设置如下基本审计内容）
