博主所在单位目前使用Oracle GoldenGate将各个业务生产库汇聚到一起做数仓实时ODS平台，源端库可能涉及Oracle、Mysql、达梦、Guassdb库。为了做增量etl以及记录每条数据的变更历史：
- 我们采用异构同步，即源端同步过来的表在ODS新增了一个etltime字段，用来记录当前数据变更时间。
- 为了记录数据的事务变更历史记录，我们将数据的变更记录映射同步到一张tab_name_audit表中。
- 为了防止源端业务库误删数据，我们将被删除的数据映射同步到一张tab_name_his表中。
- 原表映射到ods后还是正常的映射同步dml操作。
至于以上方式是怎么实现的，我这里给大家在本地电脑做一次模拟。至于GoldenGate如何安装，请看博主其他相关文章，这里就不赘述了！！！
一、GoldenGate简介
GoldenGate公司成立于1995年的美国加州旧金山， 它的名称源自旧金山闻名于世的金门大桥。
该公司于2009年9月被Oracle公司收购，在此之前Oracle和GoldGate公司就有了长达超过10年的合作关系。
GoldenGate几乎支持市面上流行的所有主流的操作系统平台和数据库。
在不同的平台生成的core文件，有不同的本地堆栈跟踪工具来分析。
GoldenGate的模式包括下图中描述的几种，其中“一对一”是GoldenGate最简单的一种模式，也是最常用的模式。
GoldenGate的大致工作原理：
GoldenGate能够解决如下不同的需求
好了，大致介绍就说到这里，相信需要本篇文章帮助的网友们，对以上肯定都很熟悉了！！！直接奔主题！
二、环境简介
1、本实验用到的OGG版本
[oracle@OGG ogg11]$ ./ggsci -v
Oracle GoldenGate Command Interpreter for Oracle
Version 11.2.1.0.3 14400833 OGGCORE_11.2.1.0.3_PLATFORMS_120823.1258_FBO
Linux, x64, 64bit (optimized), Oracle 11g on Aug 23 2012 20:20:21
Copyright (C) 1995, 2012, Oracle and/or its affiliates. All rights reserved.
2、实验中使用的重点参数
下面仅列出来两个重要参数，其他参数请参考官方文档或本博主的另一篇介绍ogg三大进程参数的博客！
--------------------NOCOMPRESSDELETES
COMPRESSDELETES | NOCOMPRESSDELETES Valid for Extract Use the
COMPRESSDELETES and NOCOMPRESSDELETES parameters to control the way
columns are written to the trail record for delete operations.
COMPRESSDELETES, the default, causes Extract to write only the primary
key to the trail for delete operations. The key provides enough
information to delete the correct target record, while restricting the
amount of data that must be processed. NOCOMPRESSDELETES sends all of
the columns to the trail. This becomes the default when a table
definition does not include a primary key or unique index. If a
substitute key was defined with the KEYCOLS option of TABLE, then
those columns are written to the trail, whether or not a real key was
defined. NOCOMPRESSDELETES also is required when using the Conflict
Detection and Resolution (CDR) feature for a DB2 database on any of
the platforms that are supported by Oracle GoldenGate. For more
information about CDR, see the Oracle GoldenGate Windows and UNIX
Administrator’s Guide. COMPRESSDELETES and NOCOMPRESSDELETES can be
used globally for all TABLE statements in the parameter file, or they
can be used as on-off switches for individual TABLE statements. These
parameters do not affect data pumps. Default COMPRESSDELETES Syntax
COMPRESSDELETES | NOCOMPRESSDELETES------------------------INSERTDELETES INSERTDELETES | NOINSERTDELETES Valid for Replicat Use the INSERTDELETES and NOINSERTDELETES
parameters to control whether or not Oracle GoldenGate converts source
delete operations to insert operations on the target database. The
parameters are table-specific. One parameter remains in effect for all
subsequent MAP statements, until the other parameter is encountered.
When using INSERTDELETES, use the NOCOMPRESSDELETES parameter so that
Extract does not compress deletes. Default NOINSERTDELETES Syntax
INSERTDELETES | NOINSERTDELETES
测试开始前使用根据生产配置提前配置好的正常同步的ogg环境，环境部署忽略，目的端配置在原有的一对三模式下增加一个对只存被删除的整条记录的
历史表tablename_DEL（被删除记录的完整记录+操作类型和被删除时间以及是前映像还是后映像）来测试
二、源库创建测试用表
1、创建有物理主键表
CREATE TABLE DEPT
(
DEPTNO NUMBER(2) NOT NULL,
DNAME VARCHAR2(14),
LOC VARCHAR2(13)
)
TABLESPACE USERS
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE
(
INITIAL 64K
NEXT 1M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
);
-- CREATE/RECREATE PRIMARY, UNIQUE AND FOREIGN KEY CONSTRAINTS
ALTER TABLE DEPT
ADD CONSTRAINT PK_DEPT PRIMARY KEY (DEPTNO)
USING INDEX
TABLESPACE USERS
PCTFREE 10
INITRANS 2
MAXTRANS 255
STORAGE
(
INITIAL 64K
NEXT 1M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
);
BEGIN
FOR I IN 1..10
LOOP
INSERT INTO DEPT VALUES(I,'A','B');
END LOOP;
COMMIT;
END;
/
2、创建无物理主键有逻辑主键表（逻辑主键：EMPNO,ENAME）
CREATE TABLE NOPK_TAB
(EMPNO NUMBER(6),
ENAME VARCHAR2(20),
SAL NUMBER(7,2),
DEPTNO NUMBER(4)
);
INSERT INTO NOPK_TAB VALUES(1110,'ZHAO',100,10);
INSERT INTO NOPK_TAB VALUES(1110,'YAN',200,20);
INSERT INTO NOPK_TAB VALUES(1111,'YAN',100,10);
INSERT INTO NOPK_TAB VALUES(1111,'DONG',100,30);
三、目标端创建审计表和只存被删除记录历史表
1、创建审计表
CREATE TABLE SCOTT.NOPK_TAB_AUDIT
(
EMPNO NUMBER(6),
ENAME VARCHAR2(20),
CSN NUMBER,
OPTIME TIMESTAMP(6),
OPTYPE VARCHAR2(20),
INSERTTIME TIMESTAMP(6),
CURDATE TIMESTAMP(6)
);
CREATE TABLE DEPT_AUDIT
(
DEPTNO NUMBER(2),
CSN NUMBER,
OPTIME TIMESTAMP(6),
OPTYPE VARCHAR2(20),
INSERTTIME TIMESTAMP(6),
CURDATE TIMESTAMP(6)
)
2、创建只存删除记录的历史表
CREATE TABLE DEPT_DEL
(
DEPTNO NUMBER(2),
DNAME VARCHAR2(14),
LOC VARCHAR2(13),
BEFORE_AFTER VARCHAR2(20),
DEL_DATE TIMESTAMP,
OP_FLAG VARCHAR2(20)
);
CREATE TABLE NOPK_TAB_DEL
(
EMPNO NUMBER(6),
ENAME VARCHAR2(20),
SAL NUMBER(7,2),
DEPTNO NUMBER(4),
BEFORE_AFTER VARCHAR2(20),
DEL_DATE TIMESTAMP,
OP_FLAG VARCHAR2(20)
);
四、停止抽取进程和投递进程
stop er *
五、添加附加日志
dblogin userid ogg password ogg
add trandata SCOTT.dept
add trandata SCOTT.NOPK_TAB,nokey,cols(EMPNO,ENAME)
六、配置抽取进程
extract e_sc
userid ogg,password ogg

setenv(ORACLE_SID="orcl")
reportcount every 10 minutes,rate

);
七、目标库应用进程配置
replicat r_sc2
setenv(NLS_LANG=AMERICAN_AMERICA.AL32UTF8)

八、启动抽取进程和投递进程
start er *
九、从源端倒数到目的端并启动应用进程
省略
十、验证是否能够只存被删除的数据完整记录
验证数据是否能够正常同步
源端分别进行插入更新删除操作：

上面操作证明对DEL表的配置确实可以捕获到源端delelte操作的记录对应的完整记录并插入表中，接下来测试当同一个主键号多次插入删除，DEL表会不会累积历史操作：
-----------------------------------------------------测试同一条记录连续插入删除多次，在DEL表中是否会存在多条相同记录：
----------------在有物理主键表测试：

也是正常的，通过上面验证，证明DEL可以累积同一主键号的删除历史纪录，证明参数NOCOMPRESSDELETES 的确如文档所说能够完整的捕获到被删除记录的完整记录并写到trail文件中|，
和参数NSERTDELETES一起使用的确可以实现历史表中只存放被删除的记录。
接下来再测试一下修改表结构，在进行增删改，del表能否正常捕获:
1.实验开始前的表结构，以及表信息（还是跟着上面过程来的，期间自己又做过别的测试，数据与上面上次做完的实验会有所不同，但是表结构还是已经改为一致了）：

源端和目的端表结构和数据均已经知道。现在在源端分别给dept表和nopk_tab 表增加一列 test number;
alter table dept add test number;
alter table nopk_tab add test number;
然后切换一下归档日志：
alter system switch logfile;
alter system switch logfile;
然后去目的端分别查看这两张表的源表和其他映射表的表结构：

但是我们也能发现，新增加的一列会放到表列的最后面，在XXXXDEL表中显示的不友好，笔者这边需求是这个DEL表的表结构要与源表一致，本人DEL表多出来的那几列是
本人为了测试方便，以及为后面update和PKUPDATE 前映像测试显示方便而加的，所以并不影响原来需求。
现在分别在源端对这两个表进行增删改操作：
insert into dept values(43,'a','a',1);
insert into nopk_tab values(1003,'aa',22,1,12);

好了，现在去目的端查看表内容：

发现仍然可以成功捕获，这是应当的。在测试一下多次插入删除同一条sql：
-----源端操作：
insert into dept values(43,'a','a',1);
insert into nopk_tab values(1003,'aa',22,1,12);
delete from dept where deptno=41;
delete from nopk_tab where empno=1001;
alter system switch logfile;

发现结果仍然是正常的。本来就应该是正常的，但是为了保险起见，才做了一下多余的测试，毕竟应用到生产，全公司的ODS平台都应用此配置，好了现在再再源端那两张表中
删除新加的test列：
alter table dept drop column test;
alter table nopk_tab drop column test;
alter system switch logfile;
接下来在目的端查看：
先看report文件：
