Using RMAN DUPLICATE DATABASE(操作笔记)

１、在auxiliary 服务器上安装oracle 软件，（不要创建数据库）

２.从target 数据库上得到pfile ,拷贝到auxiliary 相对应的位置，（修改相应的参数）

３.auxiliary服务器：根据pfile 和需要创建相应的目录。

 

(目录结构不同的,应在pfile 后面加)

*.db_file_name_convert=('/u01/app/oracle/oradata/hanmi/','/u01/oracle/oradata/hanmi')
*.log_file_name_convert=('/u01/app/oracle/oradata/hanmi/','/u01/oracle/oradata/hanmi')

/u01/app/oracle/oradata/hanmi/  是target 数据库 temp 表空间目录

/u01/oracle/oradata/hanmi           是auxiliary 数据库 temp 表空间的目录

４.创建网络配制文件listener.ora　sqlnet.ora  tnsnames.ora　使能连上target 数据库

 

５.备份target 数据库，并且与archive log 一起　拷贝到auxiliary 服务器上相同的目录

６.设置sys密码文体：

orapwd file=/u01/oracle/product/10.2.0/db_1/dbs/orapwhanmi password=hanmihanmi  entries=4

 

７.　auxiliary服务器启动到nomount 状态。

８.连接两个数据库，clone数据库：

　　[oracle@oracle ~]$ rman target sys/hanmiit@hanmi35 auxiliary sys/hanmihanmi

　　　　　　rman> run{

  DUPLICATE TARGET DATABASE TO dupdb
  # specify client-side parameter file (on same host as RMAN client) for
  # auxiliary instance if necessary
  PFILE = /dup/oracle/dbs/initDUPDB.ora
  NOFILENAMECHECK;   (目录结构相同)
}

 

目录结构不同用下面的脚本：

RUN
{
  # set new filenames for the datafiles
 set newname for datafile 1 to '/u01/oracle/oradata/hanmi/system01.dbf';

set newname for datafile 2 to '/u01/oracle/oradata/hanmi/undotbs01.dbf';
set newname for datafile 3 to '/u01/oracle/oradata/hanmi/sysaux01.dbf';
set newname for datafile 4 to '/u01/oracle/oradata/hanmi/users01.dbf';
set newname for datafile 5 to '/u01/oracle/oradata/hanmi/bjhanmi01.dbf';
set newname for datafile 6 to '/u01/oracle/oradata/hanmi/gsp01.dbf';
set newname for datafile 7 to '/u01/oracle/oradata/hanmi/unia01.dbf';
set newname for datafile 8 to '/u01/oracle/oradata/hanmi/sfa01.dbf';
set newname for datafile 9 to '/u01/oracle/oradata/hanmi/rmkunia01.dbf';
set newname for datafile 10 to '/u01/oracle/oradata/hanmi/hmp01.dbf';

duplicate target DATABASE TO hanmi LOGFILE
'/u01/oracle/oradata/redo01' size 200m,
'/u01/oracle/oradata/redo02' size 200m,
'/u01/oracle/oradata/redo03' size 200m;

}
