从Oracle数据库12c开始，可以将Oracle Clusterware和Oracle RAC配置在大型集群中，称为Oracle Flex集群。 这些集群包含...
前期回顾 MySQL Galera Clusters全解析 Part 1 Galera Cluster 简介 上节我们简单介绍了Galera Cluster，说到Galera Cluster 中各节点的事务同步是通过基于认证的复制进行的
这期的专题我们来介绍MySQL Galera Clusters 相关的内容 上个专题我们说了MySQL组复制相关的内容，这节我们说MySQL Galera Clusters ，这个和MGR在某些方面类似
单实例数据库模式 单实例模式下,一个数据库只能通过一个实例进行访问 RAC(Real Application Clusters)集群模式下,共享数据库文件,一个数据库生成多个相同的实例被用户访问。
