ogg实现oracle到sql server的同步

文章转自：http://blog.sina.com.cn/s/blog_a32eff280101e1si.html

一、源端(oracle)配置
1.创建同步测试表
   create table gg_user.t01(name varchar(20) primary key);
   create table gg_user.t02(id int primary key,name varchar(20));
   2.添加定义文件(是异构之间的传输，需要转换字段类型等处理需用到defgen工具生成定义文件)
    GGSCI (kermart) 4> edit params defgen
    defsfile D:\ggate\dirdef\t01.def
    userid gg_user,password oracle
    table gg_user.t01;
    table gg_user.t02;
  
 注意：如果有多个表，需要每个都列出来，如果这个用户所有的表都需要同步，直接就table gg_user.*;
    如果没有列出来，复制进程启动会报如下错误：
    ERROR   OGG-00423  Oracle GoldenGate Delivery for SQL Server, RPL01.prm:  Could not find definition for GG_USER.T02.
    ERROR   OGG-01668  Oracle GoldenGate Delivery for SQL Server, RPL01.prm:  PROCESS ABENDING.
    生成定义文件
D:\ggate>defgen.exe paramfile D:\ggate\dirprm\defgen.prm

Retrieving definition for GG_USER.T

 

Definitions generated for 1 table in D:\ggate\dirdef\t01.def
将t01.def拷贝到sql server ogg下的dirdef目录下。
3.添加补充日志
GGSCI (kermart) 7> dblogin userid gg_user,password oracle
GGSCI (kermart) 8> add trandata gg_user.t01
GGSCI (kermart) 8> add trandata gg_user.t02

4.添加抽取进程
GGSCI (kermart) 5> edit params ext01
extract ext01
userid gg_user,password oracle
exttrail D:\ggate\dirdat\et
DYNAMICRESOLUTION
GETTRUNCATES
TABLE gg_user.t01;
TABLE gg_user.t02;

GGSCI (kermart) 1> add extract ext01,tranlog,begin now
GGSCI (kermart) 2> add exttrail D:\ggate\dirdat\et,extract ext01

5.添加传递进程
GGSCI (kermart) 6> edit params pump01
extract pump01
userid gg_user,password oracle
rmthost 127.0.0.1,mgrport 7810
rmttrail E:\ggate\dirdat\rt
PASSTHRU
TABLE gg_user.t01;
TABLE gg_user.t02;

GGSCI (kermart) 5> add extract pump01,exttrailsource D:\ggate\dirdat\et,begin now
GGSCI (kermart) 6> add rmttrail E:\ggate\dirdat\rt,extract pump01

二、目标端(sql server)配置
1.配置ODBC数据源
    控制面板-管理工具-数据源(ODBC)，添加系统DNS，取名为test01，注意择驱动程序类型为SQL Server Native Client 10.0
    2.创建测试表（结构跟源端保持一致)
    create table hjj.t01(name varchar(20) primary key);
   create table hjj.t02(id int primary key,name varchar(20));
   3.添加checkpointtable
   GGSCI (kermart) 10> edit param ./globals
checkpointtable hjj.ckp
GGSCI (kermart) 8> dblogin sourcedb t01 userid sa password sa
GGSCI (kermart) 9> add checkpointtable hjj.ckp
   3.添加复制进程
   GGSCI (kermart) 58> edit param rpl01
   replicat rpl01
   sourcedefs E:\ggate\dirdef\t01.def
   targetdb t01 userid sa, password sa
   reperror default,discard
   discardfile E:\ggate\dirrpt\rpl.dsc append
   gettruncates
   MAP gg_user.t01, TARGET hjj.t01;
   MAP gg_user.t02, TARGET hjj.t02;

   GGSCI (kermart) 12> add replicat rpl01,exttrail E:\ggate\dirdat\rt,begin now,checkpointtable hjj.ckp
 

  三、测试
   1.启动进程
   源端：
   start ext01
   start pump01
   GGSCI (kermart) 9> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING
EXTRACT     STOPPED     EXDP        00:00:00      16:40:29

目标端：
 start rpl01
 GGSCI (kermart) 59> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING
EXTRACT     STOPPED     EXT1        00:00:00      163:48:28

REPLICAT    RUNNING     RPL01       00:00:00      00:00:04
2.在源端(oracle)进行DML操作
 SQL> insert into t01 select 'lyn'||rownum from dual connect by level<=100;

已创建100行。

SQL> commit;

提交完成。

SQL> insert into t02 select rownum,'moon'||rownum from dual connect by level<=100;

已创建100行。

SQL> commit;

提交完成。

SQL> select count(*) from t01;

  COUNT(*)
----------
       100

SQL> select count(*) from t02;

  COUNT(*)
----------
       100
3.在目标端(sql server）查看数据同步复制情况
C:\>sqlcmd -S kermart -U sa -P sa -d TEST
1> select count(*) from hjj.t01;
2> go

-----------
        100

(1 行受影响)
1> select count(*) from hjj.t02
2> go

-----------
        100

(1 行受影响)
