GoldenGate新增表

GoldenGate实施完之后，运行了一段时间，由于业务上的需求，需要增加一些新表进行同步数据，可以采用新建extract进程或使用旧的extract进程来追加同步新增加的表的数据，我这里采用的是追加的方式进行数据的抽取。[@more@]

下面是追加新增加表的操作过程：

OGG版本:OGG_for_unix_11g （V26188-01.zip）

数据库版本:9.2.0.5（源端）、11.2.0.2（目标端）

源端操作：

GGSCI>info er *

各个进程都正常运行（running）

1.增加表级附加日志

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:所有新增加的各个表的字段未超过32个字段）

查看表级别附加日志是否增加成功:

GGSCI>INFO TRANDATA GFPZ.* #查看是否打开了trandata设置，是否会执行初始化同步

2.切换归档日志

SQL>alter system archive log current;

3.停止extract 进程、停止pump进程、停止relicat进程（目标端操作）

GGSCI>stop extract xxxxx

GGSCI>stop extract xxxxx

4.配置旧的extract进程，pump进程

GGSCI>edit params extract进程

添加下面的表进入:

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进程

添加如下的表进入:

TABLE GFPZ.*;

5.开启旧的extract进程，开启旧的pump进程

GGSCI>start extract 进程

GGSCI>start pump进程

6.获得当前系统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导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'

目标端操作：

8.添加新用户（GFPZ）的表空间、用户赋予权限

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.配置旧的relicat进程

添加如下语句在旧的relicat进程里面

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导入数据

imp gfpz/gfpz_123 file=gfpz.dmp fromuser=gfpz touser=gfpz log=gfpz_imp.log

11.开启旧的relicat进程

GGSCI>start replicat 进程

12.删除repliact进程filter选项内容

当replicat进程将追加部分的数据开始同步并与源库持平以后,将replicat进程中的filter clause删除并重启replicat进程

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 ;
map gfpz.GF_SOURCE_T ,target gfpz.GF_SOURCE_T ;
map gfpz.HISGF_LEASEHOLD_T ,target gfpz.HISGF_LEASEHOLD_T ;
map gfpz.GF_IMPORT_T ,target gfpz.GF_IMPORT_T ;
map gfpz.GF_LOCATION_T ,target gfpz.GF_LOCATION_T ;
map gfpz.HISGF_LOCATION_T ,target gfpz.HISGF_LOCATION_T ;
map gfpz.GF_ACCEPT_AUDIT_T ,target gfpz.GF_ACCEPT_AUDIT_T ;
map gfpz.GF_PRIVATEPART_T ,target gfpz.GF_PRIVATEPART_T ;
map gfpz.HISGF_PRIVATEPART_T ,target gfpz.HISGF_PRIVATEPART_T ;
map gfpz.GF_EQUIPMENT_T ,target gfpz.GF_EQUIPMENT_T ;
map gfpz.GF_PRIVATEEQUIPMENT_T ,target gfpz.GF_PRIVATEEQUIPMENT_T ;
map gfpz.GF_PUBLICPART_T ,target gfpz.GF_PUBLICPART_T ;
map gfpz.HISGF_EQUIPMENT_T ,target gfpz.HISGF_EQUIPMENT_T ;
map gfpz.HISGF_PRIVATEEQUIPMENT_T ,target gfpz.HISGF_PRIVATEEQUIPMENT_T ;
map gfpz.HISGF_PUBLICPART_T ,target gfpz.HISGF_PUBLICPART_T ;
map gfpz.GF_DATA_LOG_T ,target gfpz.GF_DATA_LOG_T ;
map gfpz.GF_PRIVATEBUILD_T ,target gfpz.GF_PRIVATEBUILD_T ;
map gfpz.HISGF_PRIVATEBUILD_T ,target gfpz.HISGF_PRIVATEBUILD_T ;
map gfpz.BUILDINGAREA ,target gfpz.BUILDINGAREA ;
map gfpz.GF_PRINT_POINT_T ,target gfpz.GF_PRINT_POINT_T ;
map gfpz.HISGF_R_REALHOUSE_T ,target gfpz.HISGF_R_REALHOUSE_T ;
map gfpz.CT_DISTRICT ,target gfpz.CT_DISTRICT ;
map gfpz.EXCEL ,target gfpz.EXCEL ;

13.禁用外键

select 'alter table '||table_name||' modify constraint '||constraint_name||' disable;' from user_constraints where constraint_type='R';

14.经过验证，源端的数据成功被目标端抽取
