Redflag Linux安装Oracle 10gR2 RAC记事

今天帮助客户在RedFlag Linux上安装了一套Oracle 10gR2 RAC，这是第一次接触红旗Linux，发现其中文化和Windows办公化作的很好，X Windows启动就仿佛Windows 2000的样子。

而且红旗内置了为Oracle而设置的参数和软件包，客户装好了OS之后，我没有打任何rpm包即可正常安装Oracle软件。

基础安准过非常顺利，但是设置高内存是遇到OUT OF MEMORY的错误，Kamus遇到过：-
 

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

这和内核参数 shmall 有关，修改设置 kernel.shmall = 16475728 。

后来离开没多久，客户打电话说两台机器都挂了，我检查了一下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  6 01:02:18 ywg1 rc.sysinit: -e

发现有网卡Down的信息，问了客户，有人折腾网线。

再看message信息里有大量的pci告警信息，系统初始化之后就存在，原因未知，不知道有人遇到过没有：

安装难度不大，不过遇到不少问题
