3        修改创建参数文件(pfile/Spfile)   

 instance_name= kbdv2

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。

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
