实验环境，oraclegoldengate 安装，仅开启DML：请看
Oracle goldengate 11g （一）【DML单向复制】
实验整体思路
一、 停止所有extract、replicat进程
二、 Oracle 数据库准备
三、 添加DDL所需参数
四、 Oracle goldengate DDL 测试
一、停止所有extract、replicat进程

三、添加DDL所需参数
3-1、Add ddl support to the extract process
GGSCI(doudou-NAS) 8> view params ext1
extract ext1
userid ogg,password oracle
exttrail /opt/ogg/dirdat/tt
TRANLOGOPTIONS asmuser sys@asm,asmpassword oracle
DDL INCLUDE ALL
DDLOPTIONS ADDTRANDATA
table doudou.*;
3-2、Add ddl support to the replicat process
GGSCI(localhost.localdomain) 17> edit params rep1
replicat rep1
userid ogg ,password oracle
assumetargetdefs
dynamicresolution
DISCARDFILE ./dirrpt/rhr.dsc, append,megabytes 100
DDLERROR DEFAULT IGNORE
map doudou.*,target doudou.*;
GGSCI(doudou-NAS) 18> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EXT1 00:00:00 00:00:04
EXTRACT RUNNING PUMP1 00:00:00 00:00:01
GGSCI (localhost.localdomain)19> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
REPLICAT RUNNING REP1 00:00:00 00:00:02
到此Oracle goldengate DDL安装结束
四、Oracle goldengateDDL 测试
Source database
SQL>select * from test;
NAME
------------------------------------------------------------------------------------------------------------------------
ID
----------
兜兜
1
Target database
SQL>select * from test;
NAME
------------------------------------------------------------------------------------------------------------------------
ID
----------
兜兜
1
Source database
SQL>truncate table test;
Tabletruncated.
SQL>commit;
Commitcomplete.
SQL>select * from test;
no rowsselected
Target database
SQL>select * from test;
no rowsselected
--DDL truncate操作，已经同步到了目标库上
源库：建立一个用户xiaoqiang并建立表xiaoqiang和数据
目标库：用户被建立xiaoqiang和表xiaoqiang被建立，但是数据未同步
Source database
SQL>conn /as sysdba
Connected.
SQL>create user xiaoqiang identified by oracle;
Usercreated.
SQL>grant connect,resource to xiaoqiang;
Grantsucceeded.
SQL>conn xiaoqiang/oracle
Connected.
SQL>create table xiaoqiang (name varchar(200),id number);
Tablecreated.
SQL>insert into xiaoqiang values ('小强',1);
1 rowcreated.
SQL>commit;
Commitcomplete.
Target database
SQL>conn xiaoqiang/oracle
Connected.
SQL>select * from xiaoqiang;
no rowsselected
--DDL create user操作已经同步到了目标库，但是insert操作并没有同步，因为我们并没有配置xiaoqiang用户的DML，这里xiaoqiang用户的DDL操作之所以能同步到目标库因为我们配置了DDL INCLUDE ALL
想一想？
如果我们删除的用户是doudou，建立新用户doudou并插入数据，目标库就会用户建立，表建立，数据填入
到此证明oracle goldengate的 DDL已经成功
总结：
Oracle goldengate DDL 成功
