创建挂载点

mkdir -p /u01/app/oracle/acfsmounts/data_acfsvol3
chown oracle:oinstall /u01/app/oracle/acfsmounts/data_acfsvol3

连接到ASM创建Volume

su - oracle
[oracle@rac1 ~]$ . oraenv
ORACLE_SID = [RAC1] ? +ASM1
The Oracle base for ORACLE_HOME=/u01/app/11.2.0/grid is /u01/app/oracle
[oracle@rac1 ~]$ dbhome
/u01/app/11.2.0/grid
[oracle@rac1 ~]$ sqlplus / as sysasm

在11gR2中使用RMAN复制数据库

RMAN 可以通过复制或者克隆，从一个运行的库中复制一个备份。可以用来在远程站点上复制数据库，下面示例中源库和复制库使用同样的SID：DB11G

在源库中创建备份。

$ rman target=/
 
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN> BACKUP DATABASE PLUS ARCHIVELOG

为目标库创建password文件

$ orapwd file=/u01/app/oracle/product/11.2.0/db_1/dbs/orapwDB11G password=password entries=10

在”$ORACLE_HOME/network/admin” 中增加”tnsnames.ora” 允许目标库访问源库。

# Added to the tnsnames.ora
DB11G-SOURCE =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ol5-112-dup1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (ORACLE_SID = DB11G)
    )
  )
