Linux真机环境Oracle 10gR2 RAC 安装完成经验心得
这里说说服务器具体配置情况，System name: LinuxNode name: node1Release: 2.6.9-34.ELsmpVersion:
下面说说碰到的问题和处理方法，大家以后安装时候可以少走弯路
1.voting ,ocr问题，这2个东西困扰了我很长时间
本来我一直以为ocr 和voting是一个文件夹或者，因为直接指定RAW设备并没有这个问题
但是当直接建立好这2个文件命名的文件夹提供给cluster 安装工具时候始终报错，反复测试始终通不过
随后我考虑试试让oracle 自己建立文件夹看看，结果通过 ，随后发现蹊跷～
ocr 和 voting 是2个文件，这才明天oracle 需要提供镜像以保证 RAC集群安全，（不用镜像没有问题）
2.万恶的Oracle bug
先看下面
*** SERVICE NAME) 2008-10-25 01:45:25.039
*** SESSION ID156.1) 2008-10-25 01:45:25.039
ORA-00200: ????????
ORA-00202: ????: ''/vol4/oracledata/RACDB/control01.ctl''
ORA-27086: ?????? - ????
Linux-x86_64 Error: 37: No locks available
Additional information: 10
这个是我从 trace 文件中抓出来的一段。
情况是这样的，RAC cluster ，database 2个软件安装完成以后 通过dbca创建数据库报错。
提示无法创建控制文件，经过分析确定为linux系统问题，但是始终查不到原因，上网搜了半天想到nfs,可能是nfs文件系统错误
再通过google 发现这个是oracle 建立在nfs 文件系统上的一个bug。
解决办法
运行如下命令
service nfslock start
随后数据库可以正常创建，问题解决
3. database 软件安装问题
始终提示无法认出 nfs 的共享存储，
解决办法 将 相关自动挂载信息写入 /etc/fstab文件中并且reboot 服务器。
问题解决
