ORA-03254: unable to execute the sql in read only database ORACLE 报错 故障修复 远程处理

文档解释

ORA-03254: unable to execute the sql in read only database

Cause: Unable to create a consistent snapshot of the object in a read only database. Transaction recovery must be performed before opening the database read only.

Action: Open the database read write, allow dead transaction recovery to complete and then open the database read only.

ORA-03254:“无法在只读数据库中执行SQL”错误指示无法在数据库中执行SQL,因为数据库是只读的。

官方解释

常见案例

1. 当用户尝试将只读数据库转换为可写数据库时,可能会发生此错误。

2. 当尝试创建表,更新,删除表行及其他处理可能更改数据字典或数据的操作时,可能会发生此错误。

正常处理方法及步骤

1. 以其他用户身份连接数据库,或者在数据库中更改可写模式或关闭只读模式。

2. 将只读数据库转换为可写数据库,这样就可以执行更改或更新操作。

3. 要更改数据库以供写访问,请运行以下命令:ALTER database open;

4. 有时您可能不确定服务器是否处于只读模式,可以使用以下查询检查:SELECT db_mode FROM V$database; 如果结果是”READ ONLY“,则服务器处于只读模式。
