2.畫一個OGG數據復制的數據流圖。（示意圖另外上傳）
3.OGG有哪些進程，都有什么作用？
進程：
?? ?1.MANAGER
?? ? MANAGER 進程是GOLDENGATE的控制進程，源/目標端都有運行，
?? ? 功能：啟動、監聽及重啟Goldengate的其它進程，報告錯誤及事件。分配數據存儲空間，發布閥值報告等。
?? ?2.EXTRACT
?? ?EXTRACT 運行在源端，負責數據表或日志中捕獲數據。
?? ?3.PUMP
?? ?PUMP 進程運行在源端，功能是：將生成的TRAIL文件以數據塊的形式，通過網絡發送到目標端。
?? ?4.COLLECTOR
?? ?COLLECTOR 功能是把TRAIL傳輸的數據塊，重新組裝成TRAIL文件 。
?? ?5.REPLICAT
?? ?REPLICAT 進程運行在目標端，負責讀取TRAIL文件，并解析應用到目標數據庫。
4.OGG數據復制的機制是什么，畫出示意圖。
?? ?ogg 數據復制的機制是對ORACLE REDO日志或歸檔日志進行分析，并篩選已提交的
?? ?日志，并以通用文件 形式傳輸到目標服務器，對通用文件內容進行代碼解析，應用到目標庫。

?? ?1.8.2.2 創建replicat：
?? ?GGSCI (dg2) 8> dblogin userid ggs,password ggs
?? ?Successfully logged into database.
?? ?GGSCI (dg2) 9> add checkpointtable ggs.checkpoint
?? ?Successfully created checkpoint table ggs.checkpoint.
?? ?GGSCI (dg2) 10> add replicat repnd,exttrail /opt/app/ggs/11.2/dirdat/nd,checkpointtable ggs.checkpoint
?? ?REPLICAT added.
?? ?1.8.2.3?啟動extract及replicat
?? ?1.8.2.3.1、啟動extract?保證mgr已啟動。
?? ?GGSCI (dg1) 7> start dpend
?? ?EXTRACT DPEND is already running.
?? ?GGSCI (dg1) 8> start extnd
?? ?EXTRACT EXTND is already running.
?? ?GGSCI (dg1) 9> info all
?? ?Program???? Status????? Group?????? Lag at Chkpt? Time Since Chkpt

2.畫一個OGG數據復制的數據流圖。（示意圖另外上傳）
3.OGG有哪些進程，都有什么作用？
進程：
?? ?1.MANAGER
?? ? MANAGER 進程是GOLDENGATE的控制進程，源/目標端都有運行，
?? ? 功能：啟動、監聽及重啟Goldengate的其它進程，報告錯誤及事件。分配數據存儲空間，發布閥值報告等。
?? ?2.EXTRACT
?? ?EXTRACT 運行在源端，負責數據表或日志中捕獲數據。
?? ?3.PUMP
?? ?PUMP 進程運行在源端，功能是：將生成的TRAIL文件以數據塊的形式，通過網絡發送到目標端。
?? ?4.COLLECTOR
?? ?COLLECTOR 功能是把TRAIL傳輸的數據塊，重新組裝成TRAIL文件 。
?? ?5.REPLICAT
?? ?REPLICAT 進程運行在目標端，負責讀取TRAIL文件，并解析應用到目標數據庫。
4.OGG數據復制的機制是什么，畫出示意圖。
?? ?ogg 數據復制的機制是對ORACLE REDO日志或歸檔日志進行分析，并篩選已提交的
?? ?日志，并以通用文件 形式傳輸到目標服務器，對通用文件內容進行代碼解析，應用到目標庫。
