Oracle-11G-RAC及负载均衡搭建手册

1、Oracle 11G R2 RAC安装手册一、 基础知识1. RAC是什么RAC，全称real application clusters，译为“实时应用集群”，是Oracle新版数据库中采用的一项新技术，是高可用性的一种，也是Oracle数据库支持网格计算环境的核心技术。2. RAC的优缺点l 优点Oracle RAC支持Oracle9i、10g、11g版本，可以支持24 x 7 有效的数据库应用系统，在低成本服务器上构建高可用性数据库系统，并且自由部署应用，无需修改代码。在Oracle RAC环境下，Oracle集成提供了集群软件和存储管理软件，为用户降低了应用成本。当应用规模需要扩充时，用

2、户可以按需扩展系统，以保证系统的性能。(1) 多节点负载均衡; (2) 提供高可用：故障容错和无缝切换功能，将硬件和软件错误造成的影响最小化; (3) 通过并行执行技术提高事务响应时间-通常用于数据分析系统; (4) 通过横向扩展提高每秒交易数和连接数-通常对于联机事务系统; (5) 节约硬件成本，可以用多个廉价PC服务器代替昂贵的小型机或大型机，同时节约相应维护成本; (6) 可扩展性好，可以方便添加删除节点，扩展硬件资源。l 缺点(1) 相对单机，管理更复杂，要求更高; (2) 可能会增加软件成本3. Oracle RAC原理在一个应用环境当中，所有的服务器使用和管理同一个数据库，目的是为

3、了分散每一台服务器的工作量，硬件上至少需要两台以上的服务器，而且还需要一个共享存储设备。同时所有服务器上的OS都应该是同一类OS,根据负载均衡的配置策略，当一个客户端发送请求到某一台服务的listener后，这台服务器根据我们的负载均衡策略，会把请求发送给本机的RAC组件处理也可能会发送给另外一台服务器的RAC组件处理，处理完请求后，RAC会通过集群软件来访问共享存储设备.逻辑结构上看：l 每一个参加集群的节点有一个独立的instance，这些instance访问同一个数据库。l 每一个节点的linstance都有自己的SGA。l 每一个节点的linstance都有自己的background

4、process。l 每一个节点的linstance都有自己的redo logs。l 每一个节点的instance都有自己的undo表空间。l 所有节点都共享一份datafiles和controlfiles。三类Resource：l VIP - 虚拟IP地址(Virtual IP) l OCR - Oracle Cluster Registry(集群注册文件),记录每个节点的相关信息l Voting Disk,仲裁机制用于仲裁多个节点向共享节点同时写的行为，这样做是为了避免发生冲突。二、 RAC环境设计1. 服务器配置操作系统主机名内存网卡Redhat Enterprise Linux 5.4r
