後臺程式 說明
Oracle高可用服務 (OHAS) OHAS是伺服器啟動後開啟的第一個Grid Infrastructure元件。它被配置為以init(1)開啟，並負責生成agent程式。
Oracle Agent Grid Infrastructure使用兩個oracle代理程式。第一個，概括起來說，負責開啟一些需要訪問OCR和VOTING檔案的資源。它由OHAS建立。
第二個代理程式由CRSD建立，負責開啟所有不需要root許可權來訪問的資源。這個程式以Grid Infrastructure所屬使用者的許可權執行，並且負責在RAC11.1中racg所做的工作。
Oracle Root Agent 和 Oracle 代理程式類似，有兩個Root 代理程式被建立。 最初的代理程式由OHAS引發，它為linux系統中需要更高許可權的資源提供初始化。建立的主要後臺程式是CSSD和CRSD。反過來，CRSD將觸發另一個root代理。這個代理將開啟需要root許可權、主要和網路相關的資源
叢集就緒服務程式
(CRSD) 叢集軟體的後臺主要程式，使用oracle叢集註冊資訊來管理叢集中的資源
叢集同步服務程式
(CSSD) 管理叢集的配置和節點成員
Oracle程式監控
(OPROCD) oprocd在11.1版本中負責 I/O 隔離。它是在10.2.0.4補丁集中為linux系統引入的。在這個補丁集以前，核心hangcheck-timer 模組來做類似的任務。有趣的是，oprocd以前常被用在非linux平臺中。Grid Infrastructure用cssdagent程式來替換了oprocd程式。
事件管理器(EVM) EVM負責釋出Grid Infrastructure建立的事件
叢集時間同步服務(CTSS) CTSS服務是一個可選項，透過網路時間協定伺服器為叢集提供時間同步，這個時間同步對RAC很重要。它可以執行在兩種模式下：觀望或者活動。當NTP被啟用的時候，它執行在觀察模式，若沒有啟動NTP，它將根據主節點同步所有節點的時間。
Oracle警告服務(ONS) 負責透過快
