新增節點oracle10g rac(rhel4)_clusterware

新增新節點oracle10g rac(rhel4)_clusterware(一)

1,根據配置好的rac節點，搭建相關環境
   a,os rpm包（參考oracle document)
   b,os 配置檔案(limits.conf)
   c,/etc/hosts檔案
   d,連通新節點與儲存
   e,編輯修改/boot/grub/grub及modprobe.conf檔案（可參對我以前的rac文件）
   f,配置raw，asm根據已有rac節點,當然若啟用了ocfs，請查閱相關文件
   g,把相關的許可權及授權動作寫入/etc/rc.d/rc.local（可查閱已存rac節點）
2,在已有rac節點以oracle使用者執行addnodes.sh指令碼
3,以上指令碼執行，可能會提示所選節點capitek3不可訪問（這是三節點的ssh通訊配置有問題，重配就可）；若cluster未啟動，報錯如下：
  rac 啟動與addnodes.sh錯誤日誌關係
[root@capitek1 logs]# more oraInstall2010-03-08_03-46-16AM.err

        at oracle.sysman.oii.oiic.OiicInstaller.main(OiicInstaller.java:866)
[root@capitek1 logs]#
 以上不言自喻，啟動cluster就行（表現症狀：在選擇新增節點的對話方塊中：vip and private ip名字是空的）



4,繼續執行會提示要執行一個runinstaller指令碼，先在新增節點執行它,然後繼續執行cluster軟體安裝對話方塊

5,最後在新增節點執行root.sh提示如下：
[root@capitek3 /]# /u01/app/oracle/oraInventory/orainstRoot.sh

可先用crs_stat -t與ifconfig相關clusterware服務是否正常（ps -ef)，若正常，可不用執行vipca


6,在已有節點以oracle使用者執行/u01/app/oracle/product/10.2.0/crs_1/bin/racgons add_config capitek3:6200
   (新增節點埠號資訊可取自於：more product/10.2.0/crs_1/opmn/conf/ons.config )

這就完成了新增節點rac cluster軟體的配置
