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
Creating trace directory
User ignored Prerequisites during installation
LOCAL ADD MODE
Creating OCR keys for user ‘grid‘, privgrp ‘oinstall‘..
Operation successful.
LOCAL ONLY MODE
Successfully accumulated necessary OCR keys.
Creating OCR keys for user ‘root‘, privgrp ‘system‘..
Operation successful.
CRS-4664: Node qc26702a successfully pinned.
Adding Clusterware entries to inittab

Successfully configured Oracle Grid Infrastructure for a Standalone Server
###可以看到基础资源已经注册到了oracle restart环境
grid@qc26702a:/home/grid>crsctl status res -t

###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

‘UpdateNodeList‘ was successful.
###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;
srvctl stop asm -o immediate
srvctl start asm
###修改磁盘权限
chown oracle:dba /dev/rhdiskpower*
chmod 660 /dev/rhdiskpower*
###使用kfod确认这磁盘信息都能被oracle或者grid用户准确读到
grid@qc26702a:/home/grid>kfod asm_diskstring=‘/dev/rhdiskpower*‘ disks=all
