配置Goldengate从Oracle到PostgreSQL的同步复制

1、平台环境

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：

直接安装goldengate for oracle 11g

配置环境变量

[oracle@rhel6ogg]$vi~/.bash_profile
#添加
exportLD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH
exportPATH=/ogg:$PATH

配置Oracle数据库

#启用归档
sys@ORCL>alterdatabasearchivelog;
#Forcinglogging
sys@ORCL>alterdatabaseforcelogging;
#添加最小附加日志
sys@ORCL>alterdatabaseaddsupplementallogdata;
#查看结果
sys@ORCL>selectLOG_MODE,FORCE_LOGGING,SUPPLEMENTAL_LOG_DATA_MINfromv$database;

LOG_MODE			FORCE_LOGSUPPLEMENTAL_LOG_DATA_MI
---------------------------------------------------------------------
ARCHIVELOG			YESYES
#创建goldengate用户
sys@ORCL>createusergoldengateidentifiedbygoldengate;
sys@ORCL>grantdbatogoldengate;
sys@ORCL>createuserzhaoxuidentifiedbyzhaoxu;
sys@ORCL>grantdbatozhaoxu;
#创建测试表
zhaoxu@ORCL>createtableggtest(col1number,col2varchar2(20));

Tablecreated.

zhaoxu@ORCL>altertableggtestaddconstraintpk_ggtestprimarykey(col1);

Tablealtered.

Postgresql端：

创建用于同步的数据库、用户和Schema，并创建测试表

解压ogg

[pguser@rhel7ogg]$tar-xvfggs_Linux_x64_Postgresql_64bit.tar

配置odbc数据源，goldengate 使用ODBC连接Postgres Database

[pguser@rhel7ogg]$pwd
/ogg
[pguser@rhel7ogg]$catodbc.ini
[ODBCDataSources]
GG_Postgres=DataDirect9.6PostgresqlWireProtocol
[ODBC]
IANAAppCodePage=106
InstallDir=/ogg
[GG_Postgres]
Driver=/ogg/lib/GGpsql25.so
Description=DataDirect9.6PostgresqlWireProtocol
Database=zhaoxu
HostName=127.0.0.1
PortNumber=5432
logonID=zhaoxu
Password=zhaoxu

[ODBCDataSources]里边配置该ODBC的别名，本文件中也就是GG_Postgres 后边的配置文件中的targetdb需要与这个对应

[ODBC]:

IANAAppCodePage指的是字符集的设置这里的106值得是UTF8，如果是4则为ISO-8859-1，注意这个应该始终和postgres的字符集设置相同，不同字符集对应的值见附件。

InstallDir对应ogg的安装目录

[GG_Postgres]:这里的名称对应的是上边ODBC的别名

Driver这里指向的是ogg安装目录下的lib/GGpsql25.so

Description是描述

Database填写数据库名称

HostName填写本机的hostname，可以解析的即可。

PosrNumber是postgres的监听端口。

logonID填写postgres的用户名

password填写postgres的密码

配置环境变量

exportLD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH
exportPATH=$PATH:/ogg
exportODBCINI=/ogg/odbc.ini

配置Ogg
