ORA-12447: policy role already exists for policy string ORACLE 报错 故障修复 远程处理

文档解释

ORA-12447: policy role already exists for policy string

Cause: The role named _DBA already exists.

Action: Correct the policy name or delete the existing policy.

ORA-12447: policy role already exists for policy string 是Oracle数据库中一个错误代码,它表示该数据库已经存在特定的策略角色,无法重复注册。

官方解释

ORA-12447 错误表明,您尝试给指定的策略字符串注册一个已经存在的策略角色。

常见案例

一个常见的案例是在DBMS_RLS.ADD_POLICY过程中,系统报告 ORA-12447 错误,因为代码将尝试注册一个已经存在的安全策略角色。

正常处理方法及步骤

1.查看要注册的策略字符串中已经存在的安全策略角色是什么,可以使用以下查询来查看已存在的策略角色:

SELECT POLICY_NAME, POLICY_ROLE FROM DBA_RLS_POLICIES;

2. 删除已存在的安全策略角色,可以使用以下命令:

EXEC DBMS_RLS.DROP_POLICY(‘owner’,’policy_name’);

3. 重新注册安全策略角色,可以使用 DBMS_RLS.ADD_POLICY 过程来注册新的安全策略角色。
