---基于备份克隆


1、创建pfile
  create pfile from spfile
添加
  log_archive_dest
compatible=


2、创建密码文件及文件夹


orapwd file=D:\app\product\11.2.0\dbhome_1\database\PWDGTJ.ora password=GTJ entries=4


3、listener.ora、tnsnames.ora创建本地命名一定要在目标数据库以及辅助数据库创建


4、注册新实例


oradim –new –sid GTJ –intpwd GTJ


5、创建spfile


create  spfile from pfile='D:\app\product\11.2.0\dbhome_1\database\initgtj.ora' 


STARTUP NOMOUNT FORCE PFILE='D:\app\product\11.2.0\dbhome_1\database\initgtj.ora' 


 alter system set compatible='11.2.0.4.0' scope=spfile;


 




DUPLICATE TARGET DATABASE
  FOR STANDBY
  FROM ACTIVE DATABASE
  PASSWORD FILE
  SPFILE 
    PARAMETER_VALUE_CONVERT '/disk1', '/disk2'
    SET DB_FILE_NAME_CONVERT '/disk1','/disk2'
    SET LOG_FILE_NAME_CONVERT '/disk1','/disk2'
    SET DB_UNIQUE_NAME 'dup1'
    SET SGA_MAX_SIZE 200M
    SET SGA_TARGET 125M;


6、连接rman 
目标数据库以及辅助数据库都要创建
rman    AUXILIARY  sys/gtj@gtjtest






7、克隆数据库
