Oracle-11G-RAC及負(fù)載均衡搭建手冊

1、Oracle 11G R2 RAC安裝手冊一、 基礎(chǔ)知識1. RAC是什么RAC，全稱real application clusters，譯為“實時應(yīng)用集群”，是Oracle新版數(shù)據(jù)庫中采用的一項新技術(shù)，是高可用性的一種，也是Oracle數(shù)據(jù)庫支持網(wǎng)格計算環(huán)境的核心技術(shù)。2. RAC的優(yōu)缺點l 優(yōu)點Oracle RAC支持Oracle9i、10g、11g版本，可以支持24 x 7 有效的數(shù)據(jù)庫應(yīng)用系統(tǒng)，在低成本服務(wù)器上構(gòu)建高可用性數(shù)據(jù)庫系統(tǒng)，并且自由部署應(yīng)用，無需修改代碼。在Oracle RAC環(huán)境下，Oracle集成提供了集群軟件和存儲管理軟件，為用戶降低了應(yīng)用成本。當(dāng)應(yīng)用規(guī)模需要擴充時，用

2、戶可以按需擴展系統(tǒng)，以保證系統(tǒng)的性能。(1) 多節(jié)點負(fù)載均衡; (2) 提供高可用：故障容錯和無縫切換功能，將硬件和軟件錯誤造成的影響最小化; (3) 通過并行執(zhí)行技術(shù)提高事務(wù)響應(yīng)時間-通常用于數(shù)據(jù)分析系統(tǒng); (4) 通過橫向擴展提高每秒交易數(shù)和連接數(shù)-通常對于聯(lián)機事務(wù)系統(tǒng); (5) 節(jié)約硬件成本，可以用多個廉價PC服務(wù)器代替昂貴的小型機或大型機，同時節(jié)約相應(yīng)維護成本; (6) 可擴展性好，可以方便添加刪除節(jié)點，擴展硬件資源。l 缺點(1) 相對單機，管理更復(fù)雜，要求更高; (2) 可能會增加軟件成本3. Oracle RAC原理在一個應(yīng)用環(huán)境當(dāng)中，所有的服務(wù)器使用和管理同一個數(shù)據(jù)庫，目的是為

3、了分散每一臺服務(wù)器的工作量，硬件上至少需要兩臺以上的服務(wù)器，而且還需要一個共享存儲設(shè)備。同時所有服務(wù)器上的OS都應(yīng)該是同一類OS,根據(jù)負(fù)載均衡的配置策略，當(dāng)一個客戶端發(fā)送請求到某一臺服務(wù)的listener后，這臺服務(wù)器根據(jù)我們的負(fù)載均衡策略，會把請求發(fā)送給本機的RAC組件處理也可能會發(fā)送給另外一臺服務(wù)器的RAC組件處理，處理完請求后，RAC會通過集群軟件來訪問共享存儲設(shè)備.邏輯結(jié)構(gòu)上看：l 每一個參加集群的節(jié)點有一個獨立的instance，這些instance訪問同一個數(shù)據(jù)庫。l 每一個節(jié)點的linstance都有自己的SGA。l 每一個節(jié)點的linstance都有自己的background

4、process。l 每一個節(jié)點的linstance都有自己的redo logs。l 每一個節(jié)點的instance都有自己的undo表空間。l 所有節(jié)點都共享一份datafiles和controlfiles。三類Resource：l VIP - 虛擬IP地址(Virtual IP) l OCR - Oracle Cluster Registry(集群注冊文件),記錄每個節(jié)點的相關(guān)信息l Voting Disk,仲裁機制用于仲裁多個節(jié)點向共享節(jié)點同時寫的行為，這樣 做是為了避免發(fā)生沖突。二、 RAC環(huán)境設(shè)計1. 服務(wù)器配置操作系統(tǒng)主機名內(nèi)存網(wǎng)卡Redhat Enterprise Linux 5.4
