卸载goldengate相关配置信息

Oracle GoldenGate软件基于数据库日志结构变化，通过解析源端在线日志或归档日志获得数据增量，再将这些变化传输并应用到目标数据库，从而实现源库和目标库的数据同步
卸载goldengate，需要停止gg相关的所有服务，删除gg所有文件所在的目录，然后删除数据库中相关的记录。

一，在源端，停止extract和管理服务：
GGSCI (rac1) 1> info all

二，在目标端，停止replicat和管理服务：
GSCI (redhat6) 6> info all

Program     Status      Group       Lag           Time Since Chkpt
