oracle 的性能优化 cuishikuan oracle SQL Server
在网上搜索了一些Oracle性能优化的文章，为了更加深层次的巩固[边写边记]，也为了可以随时查看，所以发表这篇文章。 1.ORACLE采用自下而上的顺序解析WHERE子句，根据这个原理，表之间的连接必须写在其他WHERE条件之前，那些可以过滤掉最大数量记录的条件必须写在WHERE子句的末尾。（这点本人曾经做过实例验证过，的确如此哦！
Shell变量和数组使用详解 daizj linux shell 变量数组
Shell 变量定义变量时，变量名不加美元符号（$，PHP语言中变量需要），如： your_name="w3cschool.cc" 注意，变量名和等号之间不能有空格，这可能和你熟悉的所有编程语言都不一样。同时，变量名的命名须遵循如下规则：首个字符必须为字母（a-z，A-Z）。中间不能有空格，可以使用下划线（_）。不能使用标点符号。不能使用ba
编程中的一些概念，KISS、DRY、MVC、OOP、REST dcj3sjt126com REST
KISS、DRY、MVC、OOP、REST （1）KISS是指Keep It Simple,Stupid（摘自wikipedia），指设计时要坚持简约原则，避免不必要的复杂化。（2）DRY是指Don't Repeat Yourself（摘自wikipedia），特指在程序设计以及计算中避免重复代码，因为这样会降低灵活性、简洁性，并且可能导致代码之间的矛盾。（3）OOP 即Object-Orie

正确配置Linux系统ulimit值字符串 ulimit
在Linux下面部署应用的时候，有时候会遇上Socket/File: Can’t open so many files的问题；这个值也会影响服务器的最大并发数，其实Linux是有文件句柄限制的，而且Linux默认不是很高，一般都是1024，生产服务器用其实很容易就达到这个数量。下面说的是，如何通过正解配置来改正这个系统默认值。因为这个问题是我配置Nginx+php5时遇到了，所以我将这篇归纳进
