以下檢查，最好在二臺機器上都進行操作；
檢查crs狀態:
[grid@rac1 ~]$ crsctl check crs CRS-4638: Oracle High Availability Servicesis online CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Servicesis online CRS-4533: Event Manager is online
檢查集羣節點
[grid@rac1 ~]$ olsnodes -n rac1 1 rac2 2
檢查監聽器進程
[grid@rac1 ~]$ srvctl status listener 監聽程序 LISTENER 已啓用 監聽程序 LISTENER 正在節點上運行: rac1,rac2
檢查Oracle ASM
[grid@rac1 ~]$ srvctl status asm -a ASM 正在 rac1,rac2上運行 ASM 已啓用。
檢查OCR
[grid@rac1 ~]$ ocrcheck Status of Oracle Cluster Registry is asfollows : Version: 3 Total space (kbytes): 262120 Used space (kbytes): 2248 Available space (kbytes) : 259872 ID : 1968086688 Device/File Name: +OCR_VOTE Device/File integrity check succeededDevice/File not configured Device/File not configured Device/File notconfigured Device/File not configured Cluster registry integrity check succeeded Logical corruption check bypassed due tonon-privileged user
檢查表決磁盤
[grid@rac1 ~]$ crsctl query css votedisk ## STATE File Universal Id File Name Diskgroup -- ----- ----------------- ------------------ ONLINE 433b29a662934f14bf5ce26f5c5f1bbf (ORCL:OCR_VOTE01) [OCR_VOTE]
安裝oracle11gR2
[oracle@rac1 ~]$ unziplinux.x64_11gR2_database_1of2.zip [oracle@rac1 ~]$ unziplinux.x64_11gR2_database_2of2.zip [oracle@rac1 ~]$ cd database/ [oracle@rac1 database]$ ./runInstaller
在二臺機器上運行腳本 [root@rac1 ~]#/u01/app/oracle/product/11.2.0/db_1/root.sh Running Oracle 11g root.sh script... The following environment variables are setas: ORACLE_OWNER= oracle ORACLE_HOME= /u01/app/oracle/product/11.2.0/db_1 Enter the full pathname of the local bindirectory: [/usr/local/bin]: The file "dbhome" already existsin /usr/local/bin.

創建數據庫
# su – oracle $ dbca
至此，oracle 11gr2 rac安裝完成,可以使用plsql進行連接測試即可
