实战:nid修改oracle11gR2数据库名

 

1.查看数据库信息
show parameter instance_name

show parameter db_name 

show parameter service_name 
 

select dbid from v$database; 

2.正常关闭数据库

sqlplus / as sysdba

SQL>shutdown immediate
3.启动数据库到mount模式

SQL>startup mount

4.确认LISTENER是启动的
lsnrctl status

5.修改数据库名

host nid target=sys/password dbname=ocp setname=y

 

# Change database ID and database name ORATEST to TEST? (Y/[N]) => y 

6.修改参数文件

shutdown immediate

startup nomount;

create pfile='E:\app\Administrator\admin\test\pfile\initocp.ora' from spfile;

将参数文件:
E:\app\Administrator\admin\test\pfile\initocp.ora中:

db_domain=""
db_name=ocp

shutdown immediate

7.重设密码文件

host orapwd file=E:\app\Administrator\product\11.2.0\dbhome_1\database\PWDocp.ora password=password entries=5

-----windows平台需要8.9两步-----
8.重新创建服务

更改instance_name

net stop OracleServiceTEST

oradim -delete -sid test

 

oradim -new -sid ocp -STARTMODE auto  -SRVCSTART system

 

9.修改注册表SID

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDb11g_home1\ORACLE_SID

值修改为ocp

10.启动数据库

sqlplus / as ysdba

startup pfile='E:\app\Administrator\admin\test\pfile\initocp.ora'

 

select dbid,name from v$database;

 

 

11.新建spfile

create spfile from pfile='E:\app\Administrator\admin\test\pfile\initocp.ora';

12.重新加载监听文件

lsnrctl reload
