oracle中11.2 RAC安裝新主機，識別老儲存-3-配置老儲存的資料庫

安裝Oracle 11.2.0.4資料庫軟體，然後執行root.sh，這個沒有特別的東西，略。
之後，我們需要修改ORACLE RDBMS的oracle二進位檔案的許可權，讓oracle 資料庫進程可以擷取ASM磁碟組。
[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，這裡的/u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle就是安裝ORACLE RDBMS的ORACLE_HOME。
然後，將資料庫添加到CRS中，啟動資料庫：
[oracle@lunar5 ~]$ srvctl add database -d lunar -n lunar5 -o $ORACLE_HOME -p +DATADG2/LUNAR/PARAMETERFILE/spfile.272.892409049 -s OPEN -y AUTOMATIC -a "TEMPDG,DATADG1,DATADG2,DATADG3" -t IMMEDIATE
[oracle@lunar5 ~]$
檢查資料庫在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:

Database is administrator managed
[oracle@lunar5 ~]$
啟動資料庫：
[oracle@lunar5 ~]$ srvctl start database -d lunar
[oracle@lunar5 ~]$
檢查crs的狀態：
[root@lunar5 ~]# crsctl status res -t

至此，整個使用新主機識別老儲存的RAC（主要是識別ASM）就完成了。如果是檔案系統的環境，比這個簡單很多，ASM的全部可以省略了。
