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@rhel6 ogg]$ vi ~/.bash_profile #添加 export LD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH export PATH=/ogg:$PATH
配置Oracle数据库
#启用归档 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; #查看结果 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 #创建goldengate用户 sys@ORCL>create user goldengate identified by goldengate; sys@ORCL>grant dba to goldengate; sys@ORCL>create user zhaoxu identified by zhaoxu; sys@ORCL>grant dba to zhaoxu; #创建测试表 zhaoxu@ORCL>create table ggtest (col1 number, col2 varchar2(20)); Table created. zhaoxu@ORCL>alter table ggtest add constraint pk_ggtest primary key(col1); Table altered.

PostgreSQL端：
创建用于同步的数据库、用户和Schema，并创建测试表
postgres=# create database zhaoxu; postgres=# create user zhaoxu superuser password 'zhaoxu'; postgres=# \c zhaoxu zhaoxu zhaoxu=# create schema zhaoxu; CREATE SCHEMA zhaoxu=# \dn List of schemas Name | Owner --------+-------- public | pguser zhaoxu | zhaoxu zhaoxu=# CREATE TABLE ggtest zhaoxu-# ( zhaoxu(# col1 integer NOT NULL, zhaoxu(# col2 varchar(20), zhaoxu(# CONSTRAINT pk_ggtest PRIMARY KEY (col1) zhaoxu(# ); CREATE TABLE zhaoxu=# \d List of relations Schema | Name | Type | Owner --------+--------+-------+-------- zhaoxu | ggtest | table | zhaoxu
解压ogg
[pguser@rhel7 ogg]$ tar -xvf ggs_Linux_x64_PostgreSQL_64bit.tar
配置odbc数据源，goldengate 使用ODBC连接Postgres Database
[pguser@rhel7 ogg]$ pwd /ogg [pguser@rhel7 ogg]$ cat odbc.ini [ODBC Data Sources] GG_Postgres=DataDirect 9.6 PostgreSQL Wire Protocol [ODBC] IANAAppCodePage=106 InstallDir=/ogg [GG_Postgres] Driver=/ogg/lib/GGpsql25.so Description=DataDirect 9.6 PostgreSQL Wire Protocol Database=zhaoxu HostName=127.0.0.1 PortNumber=5432 LogonID=zhaoxu Password=zhaoxu
[ODBC Data Sources]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
export LD_LIBRARY_PATH=/ogg/lib:$LD_LIBRARY_PATH export PATH=$PATH:/ogg export ODBCINI=/ogg/odbc.ini
配置Ogg

4、测试数据同步
测试insert
#Oracle端 zhaoxu@ORCL>insert into ggtest values(1,'zhaoxu'); 1 row created. zhaoxu@ORCL>insert into ggtest values(2,'luoxi'); 1 row created. zhaoxu@ORCL>insert into ggtest values(3,'sanqi'); 1 row created. zhaoxu@ORCL>commit; Commit complete. #PostgreSQL端 zhaoxu=# select * from ggtest; col1 | col2 ------+-------- 1 | zhaoxu 2 | luoxi 3 | sanqi (3 rows)
测试delete
#Oracle端 zhaoxu@ORCL>delete from ggtest where col1=3; 1 row deleted. zhaoxu@ORCL>commit; Commit complete. zhaoxu@ORCL>select * from ggtest; COL1 COL2 ---------- ------------------------------------------------------------ 1 zhaoxu 2 luoxi #PostgreSQL端 zhaoxu=# select * from ggtest; col1 | col2 ------+-------- 1 | zhaoxu 2 | luoxi (2 rows)
测试update
#Oracle端 zhaoxu@ORCL>update ggtest set col2 = 'sanqi' where col1=1; 1 row updated. zhaoxu@ORCL>commit; Commit complete. zhaoxu@ORCL>select * from ggtest; COL1 COL2 ---------- ------------------------------------------------------------ 1 sanqi 2 luoxi #PostgreSQL端 zhaoxu=# select * from ggtest; col1 | col2 ------+------- 2 | luoxi 1 | sanqi (2 rows)
