Oracle11GR2RAC及负载均衡搭建手册

1、Oracle 11G R2 RAC安装手册基础知识RAC是什么RAC，全称rreal aappliccationn clussters，译译为“实时应应用集群”，是是Oraclle新版数据据库中采用的的一项新技术术，是高可用用性的一种，也也是Oraccle数据库库支持网格计计算环境的核核心技术。RAC的优缺点点优点Oracle RAC支持持Oraclle9i、10g、11g版本，可可以支持244 x 7 有效的数据据库应用系统统，在低成本本服务器上构构建高可用性性数据库系统统，并且自由由部署应用，无无需修改代码码。在Oraacle RRAC环境下下，Oraccle集成提提供了集群软软件和存储管

2、管理软件，为为用户降低了了应用成本。当当应用规模需需要扩充时，用用户可以按需需扩展系统，以以保证系统的的性能。多节点负载均衡衡; 提供高可用：故故障容错和无无缝切换功能能，将硬件和和软件错误造造成的影响最最小化; 通过并行执行技技术提高事务务响应时间通常常用于数据分分析系统; 通过横向扩展提提高每秒交易易数和连接数数通常常对于联机事事务系统; 节约硬件成本，可可以用多个廉廉价PC服务器代代替昂贵的小小型机或大型型机，同时节节约相应维护护成本; 可扩展性好，可可以方便添加加删除节点，扩扩展硬件资源源。缺点相对单机，管理理更复杂，要要求更高; 可能会增加软件件成本Oracle RAC原理理在一个应

3、用环境境当中，所有有的服务器使使用和管理同同一个数据库库，目的是为为了分散每一一台服务器的的工作量，硬硬件上至少需需要两台以上上的服务器，而而且还需要一一个共享存储储设备。同时时所有服务器器上的OS都应该是是同一类OSS,根据负载载均衡的配置置策略，当一一个客户端发发送请求到某某一台服务的的listeener后，这这台服务器根根据我们的负负载均衡策略略，会把请求求发送给本机机的RAC组件处处理也可能会会发送给另外外一台服务器器的RAC组件处处理，处理完完请求后，RRAC会通过过集群软件来来访问共享存存储设备.逻辑结构上看：每一个参加集群群的节点有一一个独立的iinstannce，这些些inst

4、aance访问问同一个数据据库。每一个节点的llinstaance都有有自己的SGGA。每一个节点的llinstaance都有有自己的baackgroound pprocesss。每一个节点的llinstaance都有有自己的reedo loogs。每一个节点的iinstannce都有自自己的unddo表空间。所有节点都共享享一份dattafilees和contrrolfilles。三类Resouurce：VIP - 虚虚拟IP地址(Virrtual IP) OCR - OOraclee Clusster RRegisttry(集群群注册文件),记录每个个节点的相关关信息Voting Disk

5、,仲裁机制用用于仲裁多个个节点向共享享节点同时写写的行为，这这样 做是为了避避免发生冲突突。RAC环境设计计服务器配置操作系统主机名内存网卡Redhat Enterrprisee Linuux 5.44rac12Geth0（Puublic）eth1（Prrive）Redhat Enterrprisee Linuux 5.44rac22Geth0（Puublic）eth1（Prrive）用户组规划GroupNaameGroupIDD说明HOSTl501Oracle清清单和软件所所有者rac1，raac2i504Oracle自自动存储管理理组rac1，raac2asmdba506ASM数据库管管理
