以Oracle为源端，PostgreSQL为目标端为例。
在源端和目标端都需要部署GoldenGate的软件。
如
GoldenGate for Oracle, 使用oci连接数据库
GoldenGate for PostgreSQL, 使用ODBC连接数据库(没有使用libpq是个遗憾啊)
数据流并不是直接入库，而是写入目标端goldengate接收到一个本地文件，然后再解析本地文件，写入目标端数据库。
说明
GGSCI (ggos) 表示Oracle端的goldengate
GGSCI (ggpgt) 表示PostgreSQL端的goldengate
Oracle端部署，假设数据库已经安装好了。
确保Oracle处于归档打开的状态。

Installing and setting up Oracle GoldenGate on the PostgreSQL machine
Then add the lib directory to the LD_LIBRARY_PATH and PATH
export LD_LIBRARY_PATH=/data/pgsql/lib:/data/pgsql/ggs/lib
export PATH=/data/pgsql/bin:/data/pgsql/ggs:$PATH ODBC驱动已打包在GoldenGate安装包，但是需要自己创建odbc.ini配置文件。
配置文件内容举例，
GoldenGate uses an ODBC connection to connect to the Postgres database.
The ODBC driver is shipped with the installation and on Unix you have to create the ODBC configuration file which is commonly called odbc.ini on your own
Here the file I used
[postgres@ggpgt ggs]$ pwd
/data/pgsql/ggs
[postgres@ggpgt ggs]$ cat odbc.ini
[ODBC Data Sources]
GG_Postgres=DataDirect 6.1 PostgreSQL Wire Protocol
[ODBC]
IANAAppCodePage=106
InstallDir=/data/pgsql/ggs
[GG_Postgres]
Driver=/data/pgsql/ggs/lib/GGpsql25.so
Description=DataDirect 6.1 PostgreSQL Wire Protocol
Database=repdb
HostName=ggpgt
PortNumber=1521
LogonID=zwc
Password=zwc 配置ODBC环境变量
Finally we need to export an ODBC environment variable which is called ODBCINI and points to the odbc.ini file we just created
export ODBCINI=/data/pgsql/ggs/odbc.ini 配置goldengate，包括创建必要的目录，配置manager端口，启动manager。
We've prepared the ODBC set up, now let's start with the GoldenGate set up.
Similar to the installation on the Oracle database host we first create the GoldenGate subdirectories

Demo table in Oracle and PostgreSQL
As mentioned, it is a basic set up without using initial load nor a data pump process.
So we only create a simple table in Oracle and Postgres to replicate data. My Oracle database has a user called postgres and this user will now own a table ggtest

GoldenGate extract process
In the following section we create an extract process that captures the changes for the GGTEST table in the Oracle database and copies the changes directly to the Postgres machine
Every process needs it config file, so let's create it for the extract process
GGSCI (ggos) 1> edit param epos
epos配置文件的配置如下，注意到需要配置远程主机名，远程的TRAIL文件前缀/data/pgsql/ggs/dirdat/ep，捕获的表名：
with these parameters
code
GGSCI (ggos) 3> view param epos
EXTRACT epos

My extract process is called epos and it connects as user ZWC using the password zwc to the Oracle database.
It will extract changes on the Oracle table ggtest stored in the zws schema and will put the information into a trail file on my Postgres machine.
Once we created the parameter file we can add the extract process and start it
GGSCI (ggos) 4> add extract epos, tranlog, begin now

SCN 0.1040942 (1040942) 因为是异构复制，目标端必须有一个源端生成的定义文件来告诉GG该如何转换捕获的数据。
创建定义文件
Create DEFINITIONS File
We're replicating data in a heterogeneous environment, so we need to give the process loading the data into the Postgres database more details about the data in the extract file.
This is done by creating a definitions file using defgen. As usual we have to create a parameter file
GGSCI (ggos) 17> edit param defgen
GGSCI (ggos) 17> view param defgen
DEFSFILE /u01/app/oracle/ggs/dirdef/GGTEST.def
USERID zwc, password zwc
TABLE ZWC.GGTEST; 调用defgen程序，生成defgen.prm参数文件。
Now exit from ggsci and call defgen on the command line and add the reference to the defgen parameter file just created
[oracle@ggos ggs]$ ./defgen paramfile ./dirprm/defgen.prm

Our extract process is set up to write all changes for the table GGTEST directly to the Postgres database machine into an extract file located in the dirdat directory.
So we only need a process that reads those changes from the trail file and distributes it to the Postgres database.
This process is called a replicat process running on the Postgres machine and it needs a parameter file

1 Hi Zhong Weicheng 查看目标端是否已接收到这条记录。
Check with a PostgreSQL tool if our newly inserted record is replicated
[postgres@ggpgt ggs]$ psql -U zwc -d repdb
psql (9.2.4)
Type "help" for help.
repdb=> select * from ggtest;
col1 | col2

(1 row)
repdb=> 使用logdump可以DUMP trail文件，检查其内容。
Check with GoldenGate tool logdump
[postgres@ggpgt ggs]$ ./logdump
