ORA-31649是一种通用的ORACLE错误。当Master process string在启动的协议上违反了时,就会出现这个错误。这通常是由于Master process string没有正确配置而引起的。

常见案例

ORA-31649:当数据库被重新启动时,出现了该错误,管理员发现,Master process 进程字符串没有被正确配置。

另一种情况是,当管理员尝试执行以下某些命令时,也可能出现该错误:

2)Alter database open;

3)Startup;

4)Shutdown;

解决方法

1)重新配置master process string,通常会将初始化参数更改为正确的值。

2)检查对初始化参数的读写权限。

3)检查master configuration file是否有误。

4)关闭数据库,然后手动更新master configuration file。

5)在指定的master process 进程字符串之前添加字符,以解决该问题。

6)使用以下命令来重新启动数据库:Startup mount

7)重新启动master process 并重新然后重新配置master process string:alter DATABASE open resetlogs;

8)检查数据库中是否存在损坏的blob或者clob。这可能会造成ORA-31649错误,所以应该先清理这些垃圾数据。
