使用GoldenGate 实现Oracle for Oracle 单向数据同步

实验环境数据源端： host1 ip 192.168.199.163 数据目标端： host2 ip 192.168.199.104两台机器都安装 http://www.linuxidc.com/Linux/2015-09/123120.htm 文中描述安装配置好了GoldenGate 。要实现数据的同步，Oracle源端必须满足如下设置Oracle需要运行在归档模式下SQL> startup mount

System altered.ogg安装目录下提供了一些demo的sql[oracle@localhost ogg]$ ls demo_ora_*

User altered.

SQL> grant resource to scott; #ggsci 登录数据库时需要该权限

SQL> @demo_ora_create.sql为需要同步的表，添加附加日志GGSCI （localhost.localdomain） 1> dblogin userid scott, password tiger
