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。

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。

 

wpsC7F1.tmp 

 

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。

可以看到DDL语句已经执行了，我们看看DDL语句的日志：

SESS 380011-2015-06-10 16:47:19 : DDL : ************************* Start of log for DDL sequence [14], v[ $Id: ddl_setup.sql /st_oggcore_11.2.1/8 2012/04/02 11:11:33 smijatov Exp $ ] trace level [0], owner schema of DDL package [GGUSR], objtype [TABLE] name [HR.T2]

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。
