在完成ogg的单向复制配置后,自然会想着向前推进一层,实现双向复制;在实际应用中,双向复制面临着许多问题,主要有如下几点:
1. 如果两个库同时更新同一条记录 如何处理?
2. 如果网络出现失败如何处理?
3. 如果数据不同步后如何修复?

本文介绍如何在前文的基础上简单实现ogg的双向复制!双向复制一般用于双业务中心环境下,网站空间,目前笔者的生产环境中未使用到ogg,香港空间,ogg系列的文章只是从技术上提前做一个准备,因而许多问题的细节未能理清,后续将继续学习研究!在开始之前,香港服务器,请先配置好db1-db2的单向复制(include ddl replicat)! 参考:

一:配置db1,添加checkpoint表(本文db1和db2互为source和target,因而直接采用db1和db2来标识两台数据库服务器)

二:配置db2,运行相关的脚本,支持DDL的复制

三:db2上配置extract和pump进程

四:db1上配置replicat进程

五:测试
