有点纳闷，为什么这些参数在10.2.0.1安装和升级到10.2.0.4的时候都通过检测，但是在应用补丁10.2.0.5时反而不能通过了呢？我们先看看原先的值



1：Checkingforfile-max=101365;foundfile-max=65536.Failed<<<<
这个失败，很好理解，因为processes为150，而参数65536=512*128,我们的进程数为150，大于128（fs.file-max=512xprocesses(forexample65536for128processes)，所以系统给了一个推荐值（具体怎么计算，还没弄清楚）

2：Checkingforip_local_port_range=9000-65500;foundip_local_port_range=1024-65000.Failed<<<<
这个参数，官方文档推荐就是net.ipv4.ip_local_port_range=900065500，也没啥好说的。TherunInstaller(OUI)checksmayexpectthistobetheoldguidanceof"102465000".ThenewguidancefromOracledevelopmentis"900065500".PleaseallowtherunInstaller(OUI)toproceedwiththenewguidancefromOracledevelopment.
3：关键是下面这几个参数为啥会失败，有点纳闷？
Checkingforrmem_default=1048576;foundrmem_default=262144.Failed<<<<
Checkingforrmem_max=1048576;foundrmem_max=262144.Failed<<<<
Checkcomplete.Theoverallresultofthischeckis:Failed<<<<
在官方文档RequirementsForInstallingOracle10gR2OnRHEL5/OEL5(x86_64)(文档ID421308.1)里面有下面介绍，也是上面的配置值

后面在官方文档RequirementsForInstallingOracle10gR2OnRHEL5/OEL5(x86_64)(文档ID421308.1)里面看到，这个是ORACLE的一个bug来的，可以忽略这个错误，具体见截图
