首先，参考官方文档：
If you are not a ULN customer, and you are running Red Hat Enterprise Linux or Oracle Linux, then you can obtain the Oracle Validated RPM at the following URLs:
Oracle Linux 4:
Oracle Linux 5:
1.下载 oracle-validated package
[root@ora10g ~]# cd /tmp[root@ora10g tmp]# wget https://oss.oracle.com/el5/oracle-validated/oracle-validated-1.0.0-18.el5.x86_64.rpm--2013-05-29 22:01:42-- https://oss.oracle.com/el5/oracle-validated/oracle-validated-1.0.0-18.el5.x86_64.rpmResolving oss.oracle.com... 137.254.17.12Connecting to oss.oracle.com|137.254.17.12|:443... connected.HTTP request sent, awaiting response... 200 OKLength: 15224 (15K) [application/x-rpm]Saving to: `oracle-validated-1.0.0-18.el5.x86_64.rpm'100%[========================================>] 15,224 66.6K/s in 0.2s 2013-05-29 22:01:58 (66.6 KB/s) - `oracle-validated-1.0.0-18.el5.x86_64.rpm' saved [15224/15224]
2.安装package:
[root@ora10g tmp]# yum install oracle-validated-1.0.0-18.el5.x86_64.rpm
可能需要导入RPM GPG KEY：
rpm --import http://oss.oracle.com/el5/RPM-GPG-KEY-oracle
包安装完毕后，参数已修改：

/etc/security/limits.conf：

附上本地yum配置：/etc/yum.repos.d/local.repo
