1.2.1 導讀

各位技術愛好者，看完本文後，你可以掌握如下的技能，也可以學到一些其它你所不知道的知識，~O(∩_∩)O~：

① Data Guard Broker 的配置

② Fast-Start Failover 的配置

③ Oracle DataGuard 之客戶端TAF 配置

④ 使用DGMGRL 來管理資料庫

⑤ 物理dg管理和維護的一些sql

⑥ DataGuard 客戶端特級配置

注意：本篇BLOG中程式碼部分需要特別關注的地方我都用黃色背景和紅色字型來表示，比如下邊的例子中，thread 1的最大歸檔日誌號為33，thread 2的最大歸檔日誌號為43是需要特別關注的地方。

1.2.4 本文簡介

本篇blog是基於cuug的公開課內容，我自己進行實踐的操作，影片可以參考：http://blog.itpub.net/26736162/viewspace-1624453/ ，簡介我就不多寫了，把cuug的內容直接copy過來吧，覺得還是比較有用的。

這個技術如果你不知道，不能算是ORACLE高手

這個技術如果你不知道，就不能說你會DataGuard

這個技術如果你不知道，......

本次網路課程，研究當主備庫發生切換時，如何在主庫啟動一個service，保證客戶端的連線能夠繼續，而且還能夠繼續select查詢操作，而不管主備庫是在哪臺伺服器上；同時保證新的客戶連線沒有任何的問題。本課程網路上的例子不多，陳老師花了將近一年的時間人肉搜尋，最近才找到，急不可待的要分享給大家。

1、DataGuard的配置（快速）

2、建立service

3、建立觸發器

4、主備庫切換測試

由於內容較多，我打算分為4個章節來共享給大家，貼個圖，不要奇怪，還有一個章節是實驗過程中配到的問題解決。

1.3 相關知識點掃盲

oracle Data Guard，以最低成本實現最高的資料保護。在硬體上沒有特殊要求，普通PC機即可實現。

簡單的來說，Data Guard，就是自動建立和維護生產資料庫（或主資料庫）的一個或多個事務一致的副本（備用資料庫）。如果主資料庫不可用（因為故障、維護或者災難），那麼可以啟用一個備用資料庫並使之承擔主資料庫的角色。然而，在配置完成Data Guard後，若需要實現主備資料庫間的切換，需要在主資料庫及備用資料庫上分別輸入多個命令，切換步驟稍顯麻煩。所以，一般情況下，DBA會將整個切換過程編輯成指令碼，以便自動執行，進行狀態切換。當然，oracle 也提供了工具Data Guard Broker，僅在控制端輸入一個命令就能方便實現主備資料庫間的切換。

在Data Guard Broker的基礎上，配置並啟用Fast-Start Failover，就能自動檢測發現主機故障，實現主備切換，故障轉移。

Data Guard Broker是建立在Data Guard基礎上的一個對Data Guard配置，集中管理操作的一個平臺。Broker的推出是為了簡化DG複雜的管理過程，它最大的作用就是集中化的統一管理。

配置Data Guard Broker使用到的客戶端工具是DGMGRL。它是一個命令列管理工具。

1.4 實驗部分

1.4.1 實驗目標

Data Guard Broker 的配置並完成實驗。

1.4.2 前提條件

注意前提條件，Data Guard已經成功配置完成。

1. 設定primary和standby啟動時引數檔案為spfile

2. 配置DG_BROKER_CONFIG_FILEn
DG_BROKER_CONFIG_FILEn代表2個引數，分別為DG_BROKER_CONFIG_FILE1，DG_BROKER_CONFIG_FILE2，它們是Data Guard Broker的配置檔名。它們都有預設值（windows下是在ORACLE_HOME/database目錄下，linux下是在ORACLE_HOME/dbs目錄下），所以一般我們可以不進行特別設定。

3. 設定listener
在Data Guard Broker環境中，需要在listener.ora靜態新增一個service_name為db_unique_name_DGMGRL.db_domain的註冊。這個service_name會在DGMGRL重啟資料庫的時候用到。透過DGMGRL重啟資料庫時DMON程式會先將資料庫關閉，然後DGMGRL用此service_name透過listener連線到資料庫，發出啟動命令。

4. 設定DG_BROKER_START為TRUE
這一步是啟動Data Guard Broker monitor（DMON）程式，需要在2個資料庫上面都執行下面的命令
alter system set dg_broker_start=true scope=both;

switchover to standby-database
