RAC維護基本指令

[[email protected] ~]$ olsnodes -i  /*顯示每個節點的vip
juliaz2    juliaz2-vip
juliaz3    juliaz3-vip
[[email protected] ~]$ olsnodes -n /*顯示每個節點在rac中的編号
juliaz2    1
juliaz3    2
[[email protected] ~]$ olsnodes -s /*顯示每個節點狀态
juliaz2    Active
juliaz3    Active
[[email protected] ~]$ olsnodes -l -p /*顯示local節點的私有ip位址
juliaz2    192.168.1.22
[[email protected] ~]$ olsnodes -c   /*rac cluster的名字
juliaz-cluster

           

檢視ORC叢集中的節點及狀态，這個指令位于grid infrastrcture 軟體安裝目錄下的bin子目錄，root帳号或者軟體安裝者都可以執行這個指令。

clusterware中的相關服務啟動起來之後，vip 和scan将自動産生，并且綁定在每個公共網卡上。

clusterware中的服務的程序

crs  /crsd   /*基于OCR對叢集中的資源進行管理。

css /ocssd / cssdagent  /*控制叢集中每個節點的成員資格 ，ocssdagent啟動和關閉ocssd程序，并監視這個程序的狀态，當ocssd程序停止運作時，csssdagent負責關閉整個節點

ctss/ctssd   /*負責不同節點之間的時間同步

evm/evmd  /*當crs服務服務産生事件時，負責對事件進行處理

ohas /ohasd /*負責啟動clusterware中的程序，這個程序以root使用者，随系統啟動而啟動的。

clusterware 提供了一系列指令，這些指令都位于grid infrastrucure軟體安裝目錄bin子目錄中，用root或軟體安裝者都可以執行。
