生产库是建在ASM上的两节点RAC，测试库是单节点的安装了Oracle restart，版本和生产一样同为11.2.0.3
现使用存储级的复制软件将生产库的所有DG拷贝到测试库所在的磁阵，以快速构建出一个测试环境
以下记录了存储复制完成后，测试库搭建的全过程：
如果我们安装Oracle Restart环境时选择的是"Install Oracle Grid Infrastructure for a Standalone software only"，那么安装完后还要进行如下配置，如果已经配置好了ASM那么直接进入"2、启动ASM实例，Mount磁盘组"
/////////////////
// 1、oracle restart安装后的配置
/////////////////
###root用户执行，其中ORACLE_HOME是grid用户下的变量
export DISPLAY=10.10.176.140:0.0
export ORACLE_HOME=/oracle/app/grid
$ORACLE_HOME/perl/bin/perl -I $ORACLE_HOME/perl/lib -I $ORACLE_HOME/crs/install $ORACLE_HOME/crs/install/roothas.pl
Using configuration parameter file: /oracle/app/grid/crs/install/crsconfig_params

###可以看到基础资源已经注册到了oracle restart环境

###继续进行配置，这步主要是更新oracle Inventory，以Grid用户执行
su - grid
export DISPLAY=10.10.176.140:0.0
$ORACLE_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME -defaultHomeName CLUSTER_NODES= CRS=TRUE

###使用asmca配置ASM实例，并启动ASM instance
创建过程中必须指定一块盘创建dg用于存放spfile，注意这块磁盘不能是BCV的目标磁盘，否则下次同步时信息会丢失
###ASM实例创建后检查ora.SPDG.dg(包含spfile的diskgroup)、ora.asm、ora.cssd、ora.evmd四个资源应该处于online
grid@qc26702a:/home/grid>crsctl status res -t

// 2、启动ASM实例，Mount磁盘组
/////////////////
###连接ASM实例，使用asmcmd的lsdg命令能看到刚才创建的存放spfile的DG
grid@qc26702a:/home/grid>export ORACLE_SID=+ASM
grid@qc26702a:/home/grid>asmcmd

###调整ASM初始化参数重启ASM instance
alter system set asm_diskstring='/dev/rhdiskpower*' scope=both;
