【OGG】OGG的单向DML复制配置(一)

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

[oracle@rhel6_lhr ~]$ ifconfig

一.3.2.2 dbca创建2套新环境用于实验

source端：

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！
