初学ogg，基本了解ogg原理及架构之后，趁热打铁，搭建一个简单的学习环境，以实现目标：将sourcedb数据库的2个表：sourceuser.test01和sourceuser.dept通过ogg分别同步到targetdb数据库的targetuser.test01和targetuser.dept表中，要求实现DML(insert、update、delete)同步。
基础环境
| 源端 | 目标端 | |
| 操作系统版本 | redhat 6.7 | redhat 6.7 |
| 数据库版本 | 11.2.0.4 | 11.2.0.4 |
| ogg版本 | Oracle GoldenGate 11.2.1.0.3 for Oracle 11g on Linux x86-64 | Oracle GoldenGate 11.2.1.0.3 for Oracle 11g on Linux x86-64 |
| 数据库/实例名称 | sourcedb/sourcedb | targetdb/targetdb |
(一)解压软件（源端和目标端执行）
[oracle@source-node ogg]$ unzip -q V34339-01.zip
[oracle@source-node ogg]$ ls
fbo_ggs_Linux_x64_ora11g_64bit.tar Oracle GoldenGate_11.2.1.0.3_README.txt
OGG_WinUnix_Rel_Notes_11.2.1.0.3.pdf V34339-01.zip
Oracle_GoldenGate_11.2.1.0.3_README.doc
[oracle@source-node ogg]$ tar -xvf fbo_ggs_Linux_x64_ora11g_64bit.tar
（二）配置环境变量

export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH:$GG_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export GG_HOME=/u01/app/ogg
alias ggsci='cd $GG_HOME;ggsci'

FOR
---
NO
SQL> alter database force logging;
Database altered.
SQL> select force_logging from v$database;
FOR
---
YES
（3.3）打开附加日志

SUPPLEME
--------
NO
SQL>
SQL>
SQL> alter database add supplemental log data;
Database altered.
SQL> select SUPPLEMENTAL_LOG_DATA_MIN from v$database;
SUPPLEME
--------
YES
（3.4）修改goldengate参数
SQL> show parameter golden
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
enable_goldengate_replication boolean FALSE
SQL> alter system set enable_goldengate_replication=true;
System altered.
SQL> show parameter golden
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
enable_goldengate_replication boolean TRUE
（3.5）创建goldengat用户
创建专属表空间：
create tablespace tbs_ogg datafile '/u01/app/oracle/product/11.2.0/db_1/dbs/sourcedb/tbs_ogg01.dbf' size 100m autoextend on next 10m maxsize 30g;
创建用户：
create user ogg identified by ogg default tablespace tbs_ogg;
授予权限：
grant resource to ogg;
grant create session,alter session to ogg;
grant select any dictionary to ogg;
grant flashback any table to ogg;
grant alter any table to ogg;
grant select any table to ogg;
grant execute on dbms_flashback to ogg;
（3.6）创建测试用户及数据
create user sourceuser identified by sourceuser;
grant connect,resource to sourceuser;
conn sourceuser/sourceuser
--创建表
create table test01 (id number,name varchar2(20));
--增加主键
alter table test01 add primary key(id);
--插入测试数据
insert into test01 values(1,'lijiaman');
insert into test01 values(2,'xiaoming');
insert into test01 values(3,'xiaohua');
--创建表
create table dept (deptno number,dname varchar2(14),loc varchar2(13));
--增加主键
alter table dept add primary key(deptno);
--插入测试数据
insert into dept values(10,'ACCOUNTING','NEW YORK');
insert into dept values(20,'RESEARCH','DALLAS');
insert into dept values(30,'SALES','CHICAGO');
insert into dept values(40,'OPERATIONS','BOSTON');
（3.7）导出数据（使用数据泵）
step1:创建路径
$[/home/oracle] mkdir datapump
$[/home/oracle] sqlplus sys/passwd as sysdba
sql > create or replace DIRECTORY exp_dir as '/home/oracle/datapump'
step2:为导出数据的用户授权
SQL> GRANT READ,WRITE ON DIRECTORY exp_dir TO sourceuser;
SQL> GRANT DATAPUMP_EXP_FULL_DATABASE TO sourceuser;
step3:执行数据导出
$[/home/oracle/datapump]expdp sourceuser/sourceuser directory = exp_dir dumpfile = sourcedb_table.dmp logfile = sourcedb_table.log tables = sourceuser.test01,sourceuser.dept;
（四）目标端数据库配置
（4.1）创建goldengat用户

创建用户：
create user ogg identified by ogg default tablespace tbs_ogg;
授予权限：
grant resource to ogg;
grant create session,alter session to ogg;
grant select any dictionary to ogg;
grant flashback any table to ogg;
grant alter any table to ogg;
grant select any table to ogg;
grant execute on dbms_flashback to ogg;

（4.3）导入源端已经导出的数据（初始化数据）
step1：创建路径
$[/home/oracle] mkdir datapump
$[/home/oracle] sqlplus sys/passwd as sysdba
sql > create or replace DIRECTORY imp_dir as '/home/oracle/datapump';
（2）为导入数据的用户授权
SQL> GRANT READ,WRITE ON DIRECTORY imp_dir TO targetuser;
SQL> GRANT DATAPUMP_IMP_FULL_DATABASE TO targetuser;
（3）将文件拷贝过来（在源端执行）
cd /home/oracle/datapump
scp sourcedb_table.dmp oracle@192.168.10.12:/home/oracle/datapump
（4）执行导入
$[/home/oracle/datapump]impdp targetuser/targetuser directory=imp_dir dumpfile =sourcedb_table.dmp remap_schema=sourceuser:targetuser;

（七）测试ogg复制功能
1.在sourceuser.test01表中插入数据，发现targetuser.test01中有新数据进入；
2.在源端执行delete from test01并提交，目标端targetuser.test01中的数据也全部删除；
3.对源表非主键列进行update操作：update dept set loc='sichuan' where deptno=40，目标端也自动更新；
4.对源表主键列进行update操作：update dept set deptno=deptno+1，目标端也自动更新；
