【OGG】OGG的单向复制配置-支持DDL(二)
一.1 BLOG文档结构图
一.2 前言部分
一.2.1 导读
各位技术爱好者，看完本文后，你可以掌握如下的技能，也可以学到一些其它你所不知道的知识，~O(∩_∩)O~：
① OGG的单向DDL实时复制功能
注意：本篇BLOG中代码部分需要特别关注的地方我都用黄色背景和红色字体来表示，比如下边的例子中，thread 1的最大归档日志号为33，thread 2的最大归档日志号为43是需要特别关注的地方。

【OGG】OGG的单向DML复制配置(一):http://blog.itpub.net/26736162/viewspace-1696020/
一.2.4 本文简介
本文基于OGG的DML复制功能，加上DDL复制功能，后续会推出系列的OGG配置，包括双向复制，还有rac到单实例的复制等等，主要参考网址为：http://ylw6006.blog.51cto.com/all/470441/16 ，非常感谢斩月大师。
一.3 实验部分
一.3.1 实验目标
配置2台服务器，搭建OGG,实现hr用户下的数据ddl和DML复制功能。
一.3.2 先验证之前的配置不支持DDL复制
验证之前的配置不支持DDL复制，这里在source端，新建一张表，发现无法复制到target端！target端也新建相同的表后，DML操作可以成功复制。

一.3.3 开始配置OGG支持DDL复制(在source端操作)
一.3.3.1 赋予ggusr用户相应的权限，修改全局配置文件添加ggschema参数

一.3.7 实验总结
DDL复制，我们可以从日志看出其执行的SQL语句，若DML配置熟悉的话，DDL配置就很简单了。
