安裝Oracle 11g rac for linux as 4 update 4

基本上和10g沒什麼大區別，只有一些小地方不同而已。oracle版本：11.1.0.6 for Linux x86_64[@more@]

rpm包的要求，hangcheck的配置，oracle使用者身份對等性連線，hosts配置和裸裝置配置全部與10g相同，這裡就不復述了。

主要區別一個是voting disk和ocr的大小，11g中要求均大於256m，如果不到大小則安裝cluster時會提示。另外在安裝cluster時，第一個節點執行root.sh沒有問題，而第二個節點報出:

最後超時退出，crsd.log也會迴圈報錯：

CSS is not ready. Received status 3 from CSS. Waiting for good status

後來發現是因為voting disk和ocr沒有清除乾淨，oracle給的是：

dd if=/dev/zero of=/dev/raw/raw1 bs=8192 count=12800

而我偷懶使用了：

dd if=/dev/zero of=/dev/raw/raw1 bs=8192 count=128

導致第一次安裝失敗- -

重新來過就ok了

新增加了osasm的operating system group，直接把oracle加到這個組就可以以SYSASM的許可權來管理ASM例項了
