1、平臺環境

Oracle：rhel6.7+Oracle11.2.0.4 ?ip:192.168.56.2

PostgreSQL：rhel7.2+Pg9.6.1 ?ip:192.168.56.25

Goldengate：Goldengate12.2.0.1 for oracle和Goldengate 12.2.0.1 for PostgreSQL

2、Ogg配置

Oracle端：

直接安裝goldengate for oracle 11g

配置環境變量[oracle@rhel6?ogg]$?vi?~/.bash_profile

#添加

export?LD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH

export?PATH=/ogg:$PATH

配置Oracle數據庫#啟用歸檔

sys@ORCL>alter?database?archivelog;

#Forcing?logging

sys@ORCL>alter?database?force?logging;

#添加最小附加日志

sys@ORCL>alter?database?add?supplemental?log?data;

#查看結果

sys@ORCL>select?LOG_MODE,FORCE_LOGGING,SUPPLEMENTAL_LOG_DATA_MIN?from?v$database;

LOG_MODE?????FORCE_LOG?SUPPLEMENTAL_LOG_DATA_MI

------------------------------------?---------?------------------------

ARCHIVELOG?????YES???????YES

#創建goldengate用戶

解壓ogg[pguser@rhel7?ogg]$?tar?-xvf?ggs_Linux_x64_PostgreSQL_64bit.tar

配置odbc數據源，goldengate 使用ODBC連接Postgres Database[pguser@rhel7?ogg]$?pwd

/ogg

[pguser@rhel7?ogg]$?cat?odbc.ini

[ODBC]

Description=DataDirect?9.6?PostgreSQL?Wire?Protocol

Database=zhaoxu

HostName=127.0.0.1

PortNumber=5432

LogonID=zhaoxu

Password=zhaoxu

[ODBC?Data?Sources]里邊配置該ODBC的別名，本文件中也就是GG_Postgres 后邊的配置文件中的targetdb需要與這個對應

[ODBC]:

IANAAppCodePage指的是字符集的設置?這里的106值得是UTF8，如果是4則為ISO-8859-1，注意這個應該始終和postgres的字符集設置相同，不同字符集對應的值見附件。

InstallDir對應ogg的安裝目錄

[GG_Postgres]:這里的名稱對應的是上邊ODBC的別名

Driver這里指向的是ogg安裝目錄下的lib/GGpsql25.so

Description是描述

Database填寫數據庫名稱

HostName填寫本機的hostname，可以解析的即可。

PosrNumber是postgres的監聽端口。

LogonID填寫postgres的用戶名

password填寫postgres的密碼

配置環境變量export?LD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH
