通过GoldenGate从Oracle向MySQL的单向复制
我使用VBOX虚拟机，一台已经安装ORACLE数据库与GOLDENDGATE的主机。另一台只安装了ORACLE数据库。配置数据库环境、goldengate用户
环境：我使用VBOX虚拟机，一台已经安装Oracle数据库与GOLDENDGATE的主机。另一台只安装了ORACLE数据库。
配置数据库环境、goldengate用户，安装GoldenGate等操作参考：两台Oracle之间配置OGG-未配置同步DDL
[root@bys2 ~]# mount /dev/cdrom /mnt/cdrom/

二.安装OGG-FOR-MYSQL
[oracle@bys2 ~]$ tar -xvf ggs_Linux_x86_MySQL_32bit.tar -C /u01/mysqlogg/
[oracle@bys2 mysqlogg]$ pwd
/u01/mysqlogg
[oracle@bys2 mysqlogg]$ ./ggsci
