ORACLE修改实例名和dbname方法

1 登陆数据库把数据库变成mount状态

sql 复制代码

C:\>sqlplus /nolog

2 使用NID命令来修改数据库instanc_name和dbname

sql 复制代码

 C:\>nid target=sys/oracle@drew dbname=kbdv2
DBNEWID: Release 9.2.0.1.0 - Production
Copyright (c) 1995, 2002, Oracle Corporation.  All rights reserved.
 
Connected to database DREW (DBID=2198138346)
 
Control Files in database:
    D:\ORACLE\ORADATA\TEST\CONTROL01.CTL
    D:\ORACLE\ORADATA\TEST\CONTROL02.CTL
    D:\ORACLE\ORADATA\TEST\CONTROL03.CTL
 
Change database ID and database name DREW to KBDV2? (Y/[N]) => Y
 
Proceeding with operation

SQL> shutdown immediate;
ORA-01109: 数据库未打开
 
 
已经卸载数据库。

3 修改创建参数文件(pfile/Spfile)

sql 复制代码

 instance_name=kbdv2
 
###########################################
# Miscellaneous
###########################################
compatible=9.2.0.0.0
 
###########################################
# Security and Auditing
###########################################
remote_login_passwordfile=EXCLUSIVE
 
###########################################
# Sort, Hash Joins, Bitmap Indexes
###########################################
pga_aggregate_target=25165824
sort_area_size=524288
 
###########################################
# Database Identification
###########################################
db_domain=""
db_name=kbdv2
 
SQL> CREATE SPFILE FROM PFILE='D:\oracle\admin\test\pfile\init.ora';
 
文件已创建。

4 创建修改口令文件 $区别windows系统和unix（linux）系统$

本人操作是在windows系统下的，所以先修改物理服务名

sql 复制代码

C:\>oradim -edit -sid drew -newsid kbdv2
并且修改注册表 HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME0\ORACLE_SID

如果是unix系统，就在oracle用户下修改.profile里的oracle_sid

创建口令文件

sql 复制代码

orapwd file=D:\oracle\ora92\database\PWDkbdv2.ora password=oracle entries=5

修改listener.ora和tnsname.ora文件

sql 复制代码

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
      )
    )
  )
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = d:\oracle\ora92)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = kbdv2)
      (ORACLE_HOME = d:\oracle\ora92)
      (SID_NAME = kbdv2)
    )
  )
 
 
kbdv2 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = kbdv2)
    )
  )

5 登陆数据库检查修改是否正确

sql 复制代码

SQL> startup
ORACLE 例程已经启动。
 
Total System Global Area  135338868 bytes
Fixed Size                   453492 bytes
Variable Size             109051904 bytes
Database Buffers           25165824 bytes
Redo Buffers                 667648 bytes
数据库装载完毕。
ORA-01589: 要打开数据库则必须使用 RESETLOGS 或 NORESETLOGS 选项
SQL> alter database open resetlogs;
 
数据库已更改。
 
SQL> show parameter name
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- -----------
db_file_name_convert                 string
db_name                              string      kbdv2
global_names                         boolean     FALSE
instance_name                        string      kbdv2
 
 
SQL> select instance_name from v$instance;
 
INSTANCE_NAME
----------------
kbdv2

这样数据库的instance和dbname就全部修改完成
