2 使用NID 命令来修改数据库instanc_name 和dbname
C:\>nid target=sys/oracle@drew dbname= kbdv2
DBNEWID: Release 9.2.0.1.0 - Production

3 修改创建参数文件(pfile/Spfile)
instance_name= kbdv2

###########################################
# 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
orapwd file=D:\oracle\ora92\database\PWDkbdv2.ora password=oracle entries=5
修改listener.ora 和tnsname.ora 文件
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> 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
