GoldenGate實施完之後，運行了一段時間，由於業務上的需求，需要增加一些新表進行同步數據，可以採用新建extract進程或使用舊的extract進程來追加同步新增加的表的數據，我這裏採用的是追加的方式進行數據的抽取。[@more@]
下面是追加新增加表的操作過程：
OGG版本:OGG_for_unix_11g （V26188-01.zip）
數據庫版本:9.2.0.5（源端）、11.2.0.2（目標端）
源端操作：
GGSCI>info er *
各個進程都正常運行（running）
1.增加表級附加日誌
GGSCI>dblogin userid ggfwzk@fdzy1, password sdb2$fwzk
GGSCI>ADD TRANDATA GFPZ.GF_RENTBOUCHER_T
ADD TRANDATA GFPZ.HISGF_RENTBOUCHER_T
ADD TRANDATA GFPZ.GF_ACCEPT_T
ADD TRANDATA GFPZ.GF_EXPORT_T
ADD TRANDATA GFPZ.GF_LEASEHOLD_T
ADD TRANDATA GFPZ.GF_SOURCE_T
ADD TRANDATA GFPZ.HISGF_LEASEHOLD_T
ADD TRANDATA GFPZ.GF_IMPORT_T
ADD TRANDATA GFPZ.GF_LOCATION_T
ADD TRANDATA GFPZ.HISGF_LOCATION_T
ADD TRANDATA GFPZ.GF_ACCEPT_AUDIT_T
ADD TRANDATA GFPZ.GF_PRIVATEPART_T
ADD TRANDATA GFPZ.HISGF_PRIVATEPART_T
ADD TRANDATA GFPZ.GF_EQUIPMENT_T
ADD TRANDATA GFPZ.GF_PRIVATEEQUIPMENT_T
ADD TRANDATA GFPZ.GF_PUBLICPART_T
ADD TRANDATA GFPZ.HISGF_EQUIPMENT_T
ADD TRANDATA GFPZ.HISGF_PRIVATEEQUIPMENT_T
ADD TRANDATA GFPZ.HISGF_PUBLICPART_T
ADD TRANDATA GFPZ.GF_DATA_LOG_T
ADD TRANDATA GFPZ.GF_PRIVATEBUILD_T
ADD TRANDATA GFPZ.HISGF_PRIVATEBUILD_T
ADD TRANDATA GFPZ.BUILDINGAREA
ADD TRANDATA GFPZ.GF_PRINT_POINT_T
ADD TRANDATA GFPZ.HISGF_R_REALHOUSE_T
ADD TRANDATA GFPZ.CT_DISTRICT
ADD TRANDATA GFPZ.EXCEL
（注:所有新增加的各個表的字段未超過32個字段）
查看錶級別附加日誌是否增加成功:
GGSCI>INFO TRANDATA GFPZ.* #查看是否打開了trandata設置，是否會執行初始化同步
2.切換歸檔日誌
SQL>alter system archive log current;
3.停止extract 進程、停止pump進程、停止relicat進程（目標端操作）
GGSCI>stop extract xxxxx
GGSCI>stop extract xxxxx
4.配置舊的extract進程，pump進程
GGSCI>edit params extract進程
添加下面的表進入:
TABLE GFPZ.GF_RENTBOUCHER_T;
TABLE GFPZ.HISGF_RENTBOUCHER_T;
TABLE GFPZ.GF_ACCEPT_T;
TABLE GFPZ.GF_EXPORT_T;
TABLE GFPZ.GF_LEASEHOLD_T;
TABLE GFPZ.GF_SOURCE_T;
TABLE GFPZ.HISGF_LEASEHOLD_T;
TABLE GFPZ.GF_IMPORT_T;
TABLE GFPZ.GF_LOCATION_T;
TABLE GFPZ.HISGF_LOCATION_T;
TABLE GFPZ.GF_ACCEPT_AUDIT_T;
TABLE GFPZ.GF_PRIVATEPART_T;
TABLE GFPZ.HISGF_PRIVATEPART_T;
TABLE GFPZ.GF_EQUIPMENT_T;
TABLE GFPZ.GF_PRIVATEEQUIPMENT_T;
TABLE GFPZ.GF_PUBLICPART_T;
TABLE GFPZ.HISGF_EQUIPMENT_T;
TABLE GFPZ.HISGF_PRIVATEEQUIPMENT_T;
TABLE GFPZ.HISGF_PUBLICPART_T;
TABLE GFPZ.GF_DATA_LOG_T;
TABLE GFPZ.GF_PRIVATEBUILD_T;
TABLE GFPZ.HISGF_PRIVATEBUILD_T;
TABLE GFPZ.BUILDINGAREA;
TABLE GFPZ.GF_PRINT_POINT_T;
TABLE GFPZ.HISGF_R_REALHOUSE_T;
TABLE GFPZ.CT_DISTRICT;
TABLE GFPZ.EXCEL;
GGSCI>edit params pump進程
添加如下的表進入:
TABLE GFPZ.*;
5.開啓舊的extract進程，開啓舊的pump進程
GGSCI>start extract 進程
GGSCI>start pump進程
6.獲得當前系統SCN
SQL>COL SCN FOR 999999999999999999999
SQL>variable SCN number
SQL>exec :scn := dbms_flashback.get_system_change_number
SQL>print scn
30974084141
7.export導出所有需要抽取的表
exp dbmaintain file=/tmp/gfpz.dmp log=/tmp/gfpz.log tables=GF_RENTBOUCHER_T,HISGF_RENTBOUCHER_T,GF_ACCEPT_T,GF_EXPORT_T,GF_LEASEHOLD_T,GF_SOURCE_T,HISGF_LEASEHOLD_T,GF_IMPORT_T,GF_LOCATION_T,HISGF_LOCATION_T,GF_ACCEPT_AUDIT_T,GF_PRIVATEPART_T,HISGF_PRIVATEPART_T,GF_EQUIPMENT_T,GF_PRIVATEEQUIPMENT_T,GF_PUBLICPART_T,HISGF_EQUIPMENT_T,HISGF_PRIVATEEQUIPMENT_T,HISGF_PUBLICPART_T,GF_DATA_LOG_T,GF_PRIVATEBUILD_T,HISGF_PRIVATEBUILD_T,BUILDINGAREA,GF_PRINT_POINT_T,HISGF_R_REALHOUSE_T,CT_DISTRICT,EXCEL) flashback_scn='30974084141'
目標端操作：
8.添加新用戶（GFPZ）的表空間、用戶賦予權限
SQL>create tablespace gfpz datafile '+data' size 10g segment space management auto;
SQL>drop user gfpz cascade;
SQL>create user gfpz identified by gfpz_123 default tablespace gfpz quota unlimited on gfpz;
SQL>grant connect,resource to gfpz;
9.配置舊的relicat進程
添加如下語句在舊的relicat進程裏面
GGSCI>map gfpz.GF_RENTBOUCHER_T ,target gfpz.GF_RENTBOUCHER_T ,filter (@GETENV ("TRANSACTION", "CSN")>30974084141);
map gfpz.HISGF_RENTBOUCHER_T ,target gfpz.HISGF_RENTBOUCHER_T ,filter (@GETENV ("TRANSACTION", "CSN")>30974084141);

map gfpz.EXCEL ,target gfpz.EXCEL ,filter (@GETENV ("TRANSACTION", "CSN")>30974084141);
10.import導入數據
imp gfpz/gfpz_123 file=gfpz.dmp fromuser=gfpz touser=gfpz log=gfpz_imp.log
11.開啓舊的relicat進程
GGSCI>start replicat 進程
12.刪除repliact進程filter選項內容
當replicat進程將追加部分的數據開始同步並與源庫持平以後,將replicat進程中的filter clause刪除並重啓replicat進程
map gfpz.GF_RENTBOUCHER_T ,target gfpz.GF_RENTBOUCHER_T ;
map gfpz.HISGF_RENTBOUCHER_T ,target gfpz.HISGF_RENTBOUCHER_T ;
map gfpz.GF_ACCEPT_T ,target gfpz.GF_ACCEPT_T ;
map gfpz.GF_EXPORT_T ,target gfpz.GF_EXPORT_T ;
map gfpz.GF_LEASEHOLD_T ,target gfpz.GF_LEASEHOLD_T ;

13.禁用外鍵
select 'alter table '||table_name||' modify constraint '||constraint_name||' disable;' from user_constraints where constraint_type='R';
14.經過驗證，源端的數據成功被目標端抽取
