如圖所示：源端採用Mysql庫，目標端採用Oracle庫mysql
1、OGG安裝配置（源端）sql
1、OGG下載數據庫
https://edelivery.oracle.com/EPD/Download/get_form?egroup_aru_number=14841438bash
※Mysql to Oracle注意事項※oracle
1. Supported data types for mysql
CHAR DOUBLE TINYTEXT
VARCHAR DATE MEDIUMTEXT
INT TIME LONGTEXT
TINYINT YEAR BLOB
SMALL INT DATETIME TINYBLOB
MEDIUM INT TIMESTAMP MEDIUMBLOB
BIG INT BINARY LONGBLOB
DECIMAL VARBINARY ENUM
FLOAT TEXT BIT(M)
2.Oracle GoldenGate supports InnoDB storage engine for a source MySQL database
goldengate對mysql只支持innodb引擎
因此，在建立mysql端的表的時候，要指定表爲innodb引擎。
create table test.test2(id int,name varchar(10)) engine=innodb;
3.【版本問題】當前for mysql版本的ogg11.2.1.0.1，暫不支持mysql 5.0如下，以及mysql 5.6以上。
4.【配置問題】mysql跟oracle的區別是，mysql是靠各個數據庫來劃分表，而oracle是靠用戶來劃分表，因此在配置以mysql爲源端的時候，
mysql端 [table test.test2] test指的是數據庫的名字，可是若是是oracle作源端的時候，test指的就是用戶的名字了，這裏有所區分。app
2、源端mysql庫配置socket
- 建立mysql用戶
*********************************************************************************************
注：建立mysql用戶的目的是要把goldengate安裝到mysql用戶下，
不然當ogg讀取mysql二進制索引文件
[log-bin-index=/var/lib/mysql/binary-log.index]
的時候沒有相關權限。
***********************************************************************************************
建立mysql用戶：
groupadd -g 1000 mysql
useradd -u 1000 -g mysql mysql
passwd mysql
密碼：mysql
掛載鏡像，配置yum源,內容以下:測試
[myyum]ui
name=myyumurl
baseurl=file:///mnt
enabled=1
gpgcheck=1
gpgkey=file:///mnt/RPM-GPG-KEY-CentOS-7
- 安裝mysql數據庫(root)
安裝mysql：
[root@localhost lib]# yum install -y mariadb*
已加載插件：fastestmirror, langpacks

完畢！
設置root用戶登陸密碼：
[root@localhost lib]# /usr/bin/mysqladmin -u root -h localhost -s var/lib/mysql/mysql.sock password '123'
拷貝初始參數文件/etc下：
[root@mysql2 ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
配置參數文件，並開啓二進制日誌，日誌模式爲row：
[root@mysql2 ~]#vi /etc/my.cnf
# Replication Master Server (default)
# binary logging is required for replication
#log-bin=mysql-bin
log-bin-index=/var/lib/mysql/bin-log.index
# binary logging format – mixed recommended
binlog_format=row
啓動mysql：
查看設置的參數是否生效：
MariaDB [(none)]> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | ON |
+---------------+-------+
1 row in set (0.00 sec)
建立即將同步的表：
查看test2表的屬性：
3.安裝mysql版本的goldengate
用mysql用戶安裝ogg：
設置環境變量：
vi .bash_profile
export PATH=/home/mysql/ggs
export LD_LIBRARY_PATH=/home/mysql/ggs
變量生效：
Source . bash_profile
建立安裝目錄
su - mysql
cd /home/mysql
mkdir ggs
安裝ogg：
[root@localhost mysql]# cp /goldengate/ggs_Linux_x64_MySQL_64bit.tar /home/oracle/ggs
mysql@mysql2 ggs]$ tar -xvf ggs_Linux_x64_MySQL_64bit.tar
[mysql@mysql2 ggs]$ ./ggsci

五．進行dml測試
能夠分別用不一樣的用戶對源端mysql數據庫中 test庫下的test2表進行insert、delete、update測試。
查看目標端oracle數據庫下的itpux用戶下的test3表是否同步成功。
源端insert：
目標端：
源端update:
目標端：
源端truncate（抽取，複製進程添加「gettruncates」參數）
目標端：
測試完畢。
