GoldenGate技術架構圖

從圖中可以看到：GoldenGate主要包含Manager程式、Extract程式、Pump程式、Replicat程式，下面對其一一說明：

Manager程式是GoldenGate的控制程式，它主要作用有以下幾個方面：啟動、監控、重啟GoldenGate的其他程式，報告錯誤及時間，分配資料儲存空間，釋出閥值報告等。

Extract程式執行在資料庫源端，負責從源端資料表或日誌中捕獲資料。Extract程式利用其內在的checkpoint機制，週期性地檢查並記錄其讀寫的位置，通常是寫入到本地的trail檔案。這種機制是為了保證如果Extract程式終止或者作業系統當機，我們重啟Extract程式後，GoldenGate能夠恢復到以前的狀態，從上一個斷點處繼續往下執行，而不會有任何資料損失。

Pump程式執行在資料庫源端，其作用非常簡單。如果源端使用了本地trail檔案，那麼Pump程式就會把Trail檔案以資料塊的形式透過TCP/IP協議傳送到目標端，我們下面的配置都是這種方式。Pump程式本質是Extract程式的一種特殊形式，如果不使用Trail檔案，那麼Extract程式在抽取完資料後，直接投遞到目標端。

與Pump程式相對應的叫Server Collector程式，這個程式不需要引起我們關注，因為在實際操作過程中無需對其進行任何配置，它執行在目標端，任務就是把Extract/Pump程式投遞過來的資料塊重新組裝成Trail檔案。

Replicat程式執行在目標端，是資料投遞的最後一站，負責讀取目標端Trail檔案中的內容，並將解析其解析為DML或DDL語句，然後應用到目標資料庫中。

6、第一次同步

第一次初始化載入步驟，只做一次就可以，目的是要讓源資料庫中的表和目標資料庫中的表初始化同步，初步變成一樣後就不需要在初始化了，再次初始化會出錯

第一次同步源資料庫和目標資料庫中要同步的表，源資料中表的結構和目標資料庫中表的結構要一樣，可以用IMP匯入表到目標資料庫
