本文主要是介绍Oracle linux5下安装Oracle 11g，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.实验环境
[root@ocm2 ~]# cat /proc/version
Linux version 2.6.18-164.el5 (mockbuild@ca-build10.us.oracle.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Thu Sep 3 02:16:47 EDT 20092.检查前提条件
2.1 检查硬件需求
[root@ocm2 Server]# grep MemTotal /proc/meminfo #查看RAM大小 Minimum: 1 GB of RAM Recommended: 2 GB of RAM or more
MemTotal: 2075432 kB
[root@ocm2 Server]# grep SwapTotal /proc/meminfo #查看swap space
SwapTotal: 4128760 kB| RAM | Swap Space |
|---|---|
| Between 1 GB and 2 GB | 1.5 times the size of the RAM |
| Between 2 GB and 16 GB | Equal to the size of the RAM |
| More than 16 GB | 16 GB |
[root@ocm2 Server]# uname -m #查看当前系统版本
