oracle 更改数据库名的方法（4）

9. 发现v$instance里的没有修改过来，这是因为在windows平台，继续如下操作
********如果是windows平台，v$instance里的instanc_name没有变， 继续如下操作
passwd文件通常放在oracle_home/database目录下，文件命名形式为PWDsid.ora，sid为实例名(Service_name)，
如当前的数据库名及service_name为orcl,则passwd文件为PWDorcl.ora
C:\Documents and Settings\Administrator>orapwd file=D:\oracle\product\10.2.0\db_
1\database\PWDdborcl.ora password=aibo entries=5
要注意一下，此时虽然数据库名已经改成dborcl了，但instance_name还是orcl，所以，passwd文件必须跟以前一样。否则会出错。
10. 删除以前的实例orcl
C:\Documents and Settings\Administrator>oradim -delete -sid orcl
实例已删除。
11. 创建新的实例名 dborcl
C:\Documents and Settings\Administrator>oradim -new -sid dborcl -intpwd aibo -st
artmode a -pfile D:\oracle\product\10.2.0\pfile20091022.ora
OPW-00005: 存在相同名称的文件 - 请删除或重命名
实例已创建。

检查service是否被更改
C:\Documents and Settings\Administrator>tnsping dborcl

已使用的参数文件:
D:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora
已使用 EZCONNECT 适配器来解析别名
Attempting to contact (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=dborcl.gdgg.local
))(ADDRESS=(PROTOCOL=TCP)(HOST=202.106.195.30)(PORT=1521)))
^C
测试不通过，说明dborcl配置有问题
修改tnsnames.ora文件，添加如下内容：
×××××××××××××××××××××××××××××××××××××××××××××××××××××
DBORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.56)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dborcl)
)
)
×××××××××××××××××××××××××××××××××××××××××××××××××××××
--重启监听

OK (20 毫秒)
到此所有的 数据库名（db_name)及实例名(Instance_name or Service_name) ，都已经更改
