添加進程，啟動進程報錯

 

1.0添加進程

GGSCI (t2) 22> add ext exta,tranlog,begin now
EXTRACT added.
--添加exta(ext標准命名規則a)，讀取日志，從當前開始

當配置EXTRACT進程時，捕獲DML（受支持的數據庫且配置DDL）
--extract捕獲事務已trail文件形式存儲在文件系統中，每個事務中記錄的是有序的保證了速度及數據的完整性。
--可以配置多個extract提取進程，可以對不同的對象進行操作，例如兩個extract可以與兩個replicat進程並行提取和傳輸

配置本地文件系統配置tar文件
GGSCI (t2) 25> add exttrail /home/ogg/ogg/dirdat/ab,ext exta,MEGABYTES 20
EXTTRAIL added.
目錄，及名稱名稱，會存在多個tar文件，命名自動后續增加； 進程傳輸 ext進程；tar文件大小20M
為何源端配置本地存儲tar文件,如果沒有data pump,則Extract必須將捕獲的數據操作發送至遠程目標端。如果目標端系統或網絡不可用，則源端捕獲的變更無法傳送至目標端，目標端恢復則數據同步耗時過長。 
配置本地存儲tar文件后，只要源端存在捕獲記錄，目標端短時間故障恢復后，數據泵可以將源端捕獲的數據傳送至目標端。    


提取進程組
GGSCI (t2) 26> add extract dpea,EXTTRAILSOURCE /home/ogg/ogg/dirdat/ab
EXTRACT added.
對提取進程進行追蹤
GGSCI (t2) 27> add rmttrail C:\win_oracle_11_database\ogg\ab,ext dpea,MEGABYTES 20
RMTTRAIL added.


啟動捕獲進程exta
GGSCI (t2) 30> info all –根據進程名稱，配置參數
EXTRACT     STOPPED     EXTA        00:00:00      00:31:08
