Redflag Linux安裝Oracle 10gR2 RAC記事

今天幫助客戶在RedFlag Linux上安裝了一套Oracle 10gR2 RAC，這是第一次接觸紅旗Linux，發現其中文化和Windows辦公化作的很好，X Windows啟動就仿佛Windows 2000的樣子。

而且紅旗內置了為Oracle而設置的參數和軟件包，客戶裝好了OS之后，我沒有打任何rpm包即可正常安裝Oracle軟件。

基礎安準過非常順利，但是設置高內存是遇到OUT OF MEMORY的錯誤，Kamus遇到過：
-
 

SQL> startup nomount
ORA-27102: out of memory
Linux-x86_64 Error: 28: No space LEFT ON device

這和內核參數 shmall 有關，修改設置 kernel.shmall = 16475728 。

后來離開沒多久，客戶打電話說兩臺機器都掛了，我檢查了一下message信息：

Feb  5 16:57:22 ywg1 kernel: bnx2: eth1 NIC Copper Link is Down
Feb  5 17:02:55 ywg1 syslogd 1.4.1: restart.
Feb  5 17:02:55 ywg1 syslog: syslogd startup succeeded

Feb  5 17:02:57 ywg1 crond: crond startup succeeded
Feb  6 01:02:18 ywg1 rc.sysinit: -e

發現有網卡Down的信息，問了客戶，有人折騰網線。

再看message信息里有大量的pci告警信息，系統初始化之后就存在，原因未知，不知道有人遇到過沒有：

安裝難度不大，不過遇到不少問題
