二、数据库配置
源端：mysql库配置
数据库配置文件： [root@ogg ~]# cat /etc/my.cnf # Replication Master Server (default) # binary logging is required for replication log-bin=mysql-bin # binary logging format - mixed recommended #binlog_format=mixed binlog_format=row 启动数据库服务 [root@ogg ~]# service mysql start Starting MySQL 连接数据库 [ OK ] [root@ogg ~]# mysql -h localhost -u mysql -p Enter password: Welcome to the MySQL monitor.

目标端：Oracle 库配置：
