ORA-16245: change db_name to string in the server-side parameter file (SPFILE)

文档解释

ORA-16245: change db_name to string in the server-side parameter file (SPFILE)

Cause: An ALTER DATABASE RECOVER TO LOGICAL STANDBY new-dbname command was successfully executed without a modifiable server parameter file (SPFILE).

Action: The server-side parameter file must be modified so that db_name is set to the given name before mounting the database again. You must do this by executing CREATE PFILE FROM SPFILE, editing the resulting text parameter file, and then executing CREATE SPFILE FROM PFILE.

。

官方解释

1. 禁用当前实例，关闭当前实例;

2. 识别db_name参数是否正确设定;

3. 使用v$db_unique_name函数更新db_name参数;

4. 重启实例。
