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DML实时复制功能
② 数据库的静默安装
③ OGG的安装
④ OGG下数据的初始化工作
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,后续会推出系列的OGG配置,包括DDL复制,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dml复制功能。
一.3.2 准备工作,在source和target端都配置
一.3.2.1 确保/etc/hosts配置正确
首先在source和target端确保/etc/hosts中的主机名到ip地址的解析是正确的,且127.0.0.1没有指向本主机名,这里以target端为例:
[oracle@rhel6_lhr ~]$ hostname
rhel6_lhr
[oracle@rhel6_lhr ~]$ more /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.59.130 rhel6_lhr

一.3.2.4 数据库设置
这里需要确保source端数据库运行在归档模式,且开启最小数据库附加日志,可以不用打开force logging,但是建议打开这个功能,然后在source和target端都创建用于复制的数据库账号ggusr,为了方便,这里直接赋予dba权限,如果对数据库安全要求高,可以去查询ogg文档,赋予复制需要的最小权限!

备注: 在oracle中可以通过rowid来定位某条记录,但是目标端的数据库和源端数据库的数据库可能完全不一样,所以无法通过rowid来确定源端数据库的逻辑变化,这时附加日志supplemental log便登上了表演的舞台。数据库在开启附加日志功能后,对于源端的修改操作,oracle会同时追加能够唯一标示记录的列到redo log。这样目标端数据库就可以知道源端发生了哪些具体的变化。
一.3.3 安装ogg软件,配置及启动mgr管理进程,source和target端做相同的操作
以下操作在source和target端都需要做:

一.3.4 初始化数据
初始化加载数据,在异构数据库平台(例如oracle-mysql),这个功能显得非常的有用!而在oracle-oracle的数据复制条件下,oracle推荐使用expdp/impdp工具

备注:
在target端配置replicat进程之前,通常需要在目标端的数据库中创建一个checkpoint表,这个表是基于ogg checkpoint文件的,它记录了所有ogg可恢复的checkpoint以及sequence,这个操作不是必须的,但oracle强烈建议使用它,因为它可以使得checkpoint包含在replicat的事务中,保证了可以从各类失败场景中恢复!
