pend：在元素内部的最后面添加元素,作为子元素，如：
通过jquery代码$("div").append("<p>我是通过append添加的</p>")，得到的结果是：
prepend：在元素内部的最前面添加元素,作为子元素，如：
通过jquery代码$("div").prepend("<p>我是通过prepend添加的</p>")，得到的结果是：
before:在元素的前边，作为兄弟元素添加,如：
通过jquery代码 $(".base").before("<div>我是在前边添加的兄弟节点</div>")，得到的结果是：
after:在元素的后边，作为兄弟元素添加,如：
通过jquery代码 $(".base").after("<div>我是在后边添加的兄弟节点</div>")，得到的结果是：
jQuery是一个快速、简洁的JavaScript框架，是继Prototype之后又一个优秀的JavaScript代码库（ 或JavaScript框架）。
jQuery设计的宗旨是“write Less，Do More”，即倡导写更少的代码，做更多的事情。
它封装JavaScript常用的功能代码，提供一种简便的JavaScript设计模式，优化HTML文档操作、事件处理、动画设计和Ajax交互。
jQuery的模块可以分为：入口模块、底层支持模块和功能模块。
其核心特性可以总结为：具有独特的链式语法和短小清晰的多功能接口；具有高效灵活的css选择器，并且可对CSS选择器进行扩展；拥有便捷的插件扩展机制和丰富的插件。
jQuery兼容各种主流浏览器，如IE 6.0+、FF 1.5+、Safari 2.0+、Opera 9.0+等。
适用于：Oracle Server - Enterprise Edition - Version 11.2.0.2 and later
Information in this document applies to any platform.
目的：
Rebootless Fencing 是从11.2.0.2引入的新特性，当evict 发生时，Rebootless Fencing 取代了
11.2.0.2之前的reboot 节点。Rebootless Fencing 会尝试在被驱逐的节点上 gracefully 停止 GI
以避免reboot节点。
若是Rebootless Fencing 失败了，被驱逐的节点会被reboot。本文列示了Rebootless Fencing 失败的通常原因。
细节：
1. Resources fails to stop.
If one or more resources fail to stop, rebootless fencing will fail and node will be rebooted.
In this case, rebootless fencing fails on node2 after network split brain and node 2 is rebooted as expected:
