 .选用适合的ORACLE优化器
ORACLE的优化器共有3种
A、RULE (基于规则) b、COST (基于成本) c、CHOOSE (选择性)
    设置缺省的优化器，可以通过对init.ora文件中OPTIMIZER_MODE参数的各种声明，如RULE，COST，CHOOSE，ALL_ROWS，FIRST_ROWS 。 你当然也在SQL句级或是会话(session)级对其进行覆盖。 https://blog.youkuaiyun.com/bjf2002/article/details/6250082https://blog.youkuaiyun.com/bjf2002/article/details/6250082bjf2002Tue, 15 Mar 2011 10:35:00 +0800内存访问的冲突出现在当进程申请的内存超过系统的物理内存总量时，为了处理这种情况，系统将程序与数据在内存和硬盘间进行交换。

　　控制内存交换操作(Paging)
　　大量的内存交换操作会极大地影响系统的性能，尤其是在当数据库文件创建在文件系统上时(JFS and JFS2)。在这种情况下经常访问的数据，即在SGA中存在，也同样在文件的缓存中存在。这种相同的数据在内存中缓存两次的情况，会降低内存的使用效率，从而使内存频繁进行交换操作，造成系统的I/O瓶颈，降低整个系]]>https://blog.youkuaiyun.com/bjf2002/article/details/6250079https://blog.youkuaiyun.com/bjf2002/article/details/6250079bjf2002Tue, 15 Mar 2011 10:33:00 +0800启动CDE

1,更改http server的配置文件参数KeepAlive。
原因：这个值说明是否保持客户与HTTP SERVER的连接，如果设置为ON，则请求数到达MaxKeepAliveRequests设定值时请求将排队，导致响应变慢。
 方法：打开ibm http server安装目录，打开文件夹conf，打开文件httpd.conf,查找KeepAlive值，改ON为OFF,其默认为ON
2,更改http se]]>https://blog.youkuaiyun.com/bjf2002/article/details/6250067https://blog.youkuaiyun.com/bjf2002/article/details/6250067bjf2002Tue, 15 Mar 2011 10:30:00 +0800startsrc -t ftp
stopsrc -t ftp

解决方法:
在服务器本地使用英文语言环境启动inetd进程。
首先运行停止inetd进程 #stopsrc -s inetd
然后使用英文语言环境启动inetd进程 #startsrc -e LANG=en_US -s inetd
现在再进行ftp就不会有时间戳乱码问题存在了。]]>https://blog.youkuaiyun.com/bjf2002/article/details/6250014https://blog.youkuaiyun.com/bjf2002/article/details/6250014bjf2002Tue, 15 Mar 2011 10:19:00 +0800https://blog.youkuaiyun.com/bjf2002/article/details/1634479https://blog.youkuaiyun.com/bjf2002/article/details/1634479bjf2002Fri, 01 Jun 2007 17:22:00 +0800https://blog.youkuaiyun.com/bjf2002/article/details/1634474https://blog.youkuaiyun.com/bjf2002/article/details/1634474bjf2002Fri, 01 Jun 2007 17:21:00 +0800https://blog.youkuaiyun.com/bjf2002/article/details/1634465https://blog.youkuaiyun.com/bjf2002/article/details/1634465bjf2002Fri, 01 Jun 2007 17:18:00 +0800https://blog.youkuaiyun.com/bjf2002/article/details/1634452https://blog.youkuaiyun.com/bjf2002/article/details/1634452bjf2002Fri, 01 Jun 2007 17:11:00 +0800https://blog.youkuaiyun.com/bjf2002/article/details/1634437https://blog.youkuaiyun.com/bjf2002/article/details/1634437bjf2002Fri, 01 Jun 2007 16:57:00 +0800
