Solaris 10下遷移10G RAC (八)

遇到的錯誤

錯誤

Crs我安裝了3遍，在其中一次重灌crs時，在最後執行指令碼時出錯：

bash-3.00# /oracle/app/oraInventory/orainstRoot.sh

Changing permissions of /oracle/app/oraInventory to 770.

Changing groupname of /oracle/app/oraInventory to oinstall.

The execution of the script is complete

在執行第二個指令碼時，停頓住了：

bash-3.00# /oracle/app/product/10.2/crs/root.sh

WARNING: directory '/oracle/app/product/10.2' is not owned by root

WARNING: directory '/oracle/app/product' is not owned by root

看了一下/tmp的資訊，發現有如下錯誤：

Failure in CSS initialization opening OCR.

查了一會資料，發現可能是因為hostname引起的，因為我當前的hostname是pre1，而我在配置cluster nodes時，寫的是pub-node1。解決方法是：

修改hostname為配置cluster nodes時的名稱：

hostname pub-node1

重新執行剛才出錯的指令碼：

bash-3.00# hostname pub-node1

bash-3.00# /oracle/app/product/10.2/crs/root.sh

為了下次重啟後仍然生效，修改檔案:

/etc/hostname.ce0

/etc/nodename

/etc/inet/ipnodes

把這兩個檔案的內容中pre1都修改為pub-node1

在其他節點也做類似的操作。

安裝crs時不能修改節點名稱

在安裝crs時，在節點選擇時還是顯示之前安裝錯誤時的節點資訊，且不能修改節點名稱。這是因為沒有把之前的crs資訊刪除乾淨，把安裝crs時的inventory 目錄刪除就可以

網路驗證不透過

$ ./runcluvfy.sh comp nodecon -n pre1,pre2 -verbose

Verifying node connectivity

ERROR:

User equivalence unavailable on all the nodes.

Verification cannot proceed.

Verification of node connectivity was unsuccessful on all the nodes.

在solaris下很容易遇到這個錯誤，這是因為Oracle在尋找ssh和scp命令時，去/usr/local/bin目錄下尋找，而ssh命令在/usr/bin目錄下。

相應的解決方法也很簡單，在/usr/local/bin目錄下建立一個指向/usr/bin/ssh的連結就可以了。

具體步驟是：

在需要執行cluvfy的節點上執行執行下面步驟：

用root建立連結：

bash-3.00# mkdir -p /usr/local/bin

bash-3.00# ln -s -f /usr/bin/ssh /usr/local/bin/ssh

bash-3.00# ln -s -f /usr/bin/scp /usr/local/bin/scp

在oracle使用者下再次新增ssh驗證：

$ exec /usr/bin/ssh-agent $SHELL

$ /usr/bin/ssh-add

Identity added: /export/home/oracle/.ssh/id_rsa (/export/home/oracle/.ssh/id_rsa)

Identity added: /export/home/oracle/.ssh/id_dsa (/export/home/oracle/.ssh/id_dsa)

再次執行驗證就可以成功了：

bash-3.00$ ./runcluvfy.sh comp nodecon -n pre1,pre2
