江边潮未尽，枫红一季秋

从Oracle11gR2 for linux正式提供下载，转眼一个星期过去了，粗略的翻了一下New feature，一直没有找到时间来安装。

今天在两台x86_64的Redhat AS 4U5上安装，建库，一切顺利。Oracle11gR2的安装过程已经基本傻瓜化到只需要next了。以前安装很重要的一步，就是要记得修改系统的一些内核参数，11gR2也把这一步直接纳入到安装界面中了，如果检查到系统还是使用的默认参数，会提示修改，并且给出了修改的shell脚本，只要root去跑一下就ok，当然，对于不同的产品环境，还是按照相应的规范去手工修改比较靠谱点。Redhat AS 4U5的os版本有点低，所以会检测出glibc/libaio等几个包的版本不符，因为是试验环境，我直接选择了忽略，安装还是很顺利的进行下去了，没有发现问题。

还没来得及去体验什么，中午吃了个饭回来，发现之前10.2.0.4上曾经碰到过的多个监听进程的问题，又出现了,faint：
