假如表结构如下 id(int) a(varchar) 1 1 2 2 3 10 4 20 5 3 6 30
第一种，cast 用法：cast(字段 as 数据类型) [当然是否可以成功转换，还要看数据类型强制转化时注意的问题] 实例：select cast(a as unsigned) as b from cardserver where order by b desc;
第二种，convert 用法：convert(字段,数据类型) 实例：select convert(a ,unsigned) as b from cardserver where order by b desc;
第三种，加減0法 用法：字段加0或减0操作 [在MYSQL中，varchar加减数字就会自动转换为数字操作] 实例：select a+0 as b from cardserver where order by b desc;

这里选择Oracle JRockit Real Time 3.1.2 for Java version 6 1 Linux x86-64 大概121M
http://download.oracle.com/otn/bea/jrockit/jrrt-3.1.2-1.6.0-linux-x64.bin
必需要登录后才能下载，wget不好使，用windows下载后再传到服务器上。
chmod u+x jrrt-3.1.2-1.6.0-linux-x64.bin ./jrrt-3.1.2-1.6.0-linux-x64.bin 根据提示一步步安装。 我安装在/usr/jrrt-3.1.2-1.6.0 目录下，做个软连接到/usr/jrrt ln -s /usr/jrrt-3.1.2-1.6.0 /usr/jrrt
修改环境变量，如果之前有设置，只需修改JAVA_HOME到新路径 vi /etc/profile
#set for j2sdk JAVA_HOME=/usr/jrrt export JAVA_HOME CLASSPATH=$JAVA_HOME/jre/lib/ext/jcert.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/jpda.jar:$JAVA_HOME/lib/tools.jar export CLASSPATH PATH=.:$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin export PATH关闭tomcat source /etc/profile 启动tomcat，完成

方法一：mode与elements是搭配使用
mode与elements是搭配使用的，用来指定渲染name在elements中的HTML元素为TinyMCE编辑器（可以是DIV或者Textarea），比如： mode : “exact”,elements : “example_textarea” 也可以单独用 mode : “textareas”,这样页面中所有的Textarea元素都会被渲染。
tinyMCE.init({ mode : “exact”, elements : “example_textarea”, });方法二：选项editor_selector和editor_deselector
这个选项指定一个CSS class 名，当textarea要被转换时需要。它让你通过在属性中增加CSS class 名选择特定的 textareas 转换。如果选项没有被设值，这个选项不会有任何作用。而由 mode 来指定要转换的textarea。如果你想要转换所有的编辑器，而排除特定的编辑器，请查看 editor_deselector 选项。
editor_selector 选项的使用示例：
tinyMCE.init({ … editor_selector : “mceEditor” });在 HTML 中的使用示例：
选项：editor_deselector
这个选项指定一个 CSS class 名，这样就不会将含有该class名的 textareas 转换成编辑器实例。如果没有设任何值，这个选项没有任何作用。而是由mode 选项来指定要转换的 textarea。 选项的默认值是 “mceNoEditor”，因此如果将 mceNoEditor 加入一个 textarea 的 class 属性中，这个 textarea 则不会被转换。
editor_deselector 选项的使用示例：
tinyMCE.init({ … editor_deselector : “mceNoEditor” });在 HTML 中的使用示例：

messages含有过多的crond重复信息，影响阅读

*.info;mail.none;authpriv.none;cron.none;auth.none /var/log/messages重启服务 /etc/init.d/crond restart

tomcat有内存限制，增加内存后可能会起不来.
