---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
