修改 db_unique_name

在创建DB的时候 db_unique_name设置错了。本来我是想让

db_name=itid

db_unique_name=itid1

不过想改回来很简单的。

SQL> alter system set db_unique_name='itid1' scope=spfile;

System altered.

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
