oracle中11.2 RAC安装新主机，识别老存储-3-配置老存储的数据库

安装Oracle 11.2.0.4数据库软件，然后执行root.sh，这个没有特别的东西，略。
之后，我们需要修改ORACLE RDBMS的oracle二进制文件的权限，让oracle 数据库进程可以获取ASM磁盘组。
[root@lunar5 ~]# su - grid
[grid@lunar5 ~]$ $ORACLE_HOME/bin/setasmgidwrap o=/u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle
[grid@lunar5 ~]$ ll /u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle
-rwsr-s--x 1 oracle asmadmin 239626689 Feb 15 22:09 /u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle
[grid@lunar5 ~]$
注意，这里的/u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle就是安装ORACLE RDBMS的ORACLE_HOME。
然后，将数据库添加到CRS中，启动数据库：
[oracle@lunar5 ~]$ srvctl add database -d lunar -n lunar5 -o $ORACLE_HOME -p +DATADG2/LUNAR/PARAMETERFILE/spfile.272.892409049 -s OPEN -y AUTOMATIC -a "TEMPDG,DATADG1,DATADG2,DATADG3" -t IMMEDIATE
[oracle@lunar5 ~]$
检查数据库在ocr中的配置：
[oracle@lunar5 ~]$ srvctl config database -d lunar
Database unique name: lunar
Database name: lunar5
Oracle home: /u01/app/oracle/product/11.2.0.4/dbhome_1
Oracle user: oracle
Spfile: +DATADG2/LUNAR/PARAMETERFILE/spfile.272.892409049
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: lunar
Database instances:
Disk Groups: TEMPDG,DATADG1,DATADG2,DATADG3
Mount point paths:
Services:
Type: RAC
Database is administrator managed
[oracle@lunar5 ~]$
启动数据库：
[oracle@lunar5 ~]$ srvctl start database -d lunar
[oracle@lunar5 ~]$
检查crs的状态：
[root@lunar5 ~]# crsctl status res -t

至此，整个使用新主机识别老存储的RAC（主要是识别ASM）就完成了。如果是文件系统的环境，比这个简单很多，ASM的全部可以省略了。
