备注： Oracle DG (主->备库1->备库2） 级联方式
主库： 10.118.242.216 sid_name=sfpay2
备库1： 10.118.242.215 sid_name=sfpay2 => ogg 主库
ogg库1： 10.118.230.27 sid_name=sfpay3 => ogg备库1
ogg库2： 10.118.242.214 sid_name=sfpay1 => ogg备库2
ogg 方式： 一个捕获进程，多个pump 进程（一对多方式）
ogg 一库多实例时，请配置好 setenv 参数（oracle_sid,nls_lang, oracle_home), 记住 tnsname.ora 对应好.
注意ogg source 端，target 端 时区。
ogg extract 端 不需要 做checkpoint ，以及备库只能做 DML ogg 同步，DDL 不支持。

测试结果：
source 端（DG备库1） 的所有数据初始话，都以 DG主库 为准（scn, 数据的导出）
source 端（DG备库1） 的ogg 操作，都需要在 DG 主库上执行ogg脚本，trandata log. 参数可以忽略。
1： 主库 执行ogg 脚本
2： 因standby database 不支持 ogg 的DDL 方式，注销掉所有ddl 方式。
3： ogg source端，dg 备库1 在info trandata schema.* 时，可能为disabled 状态，但是DG主库enable 即可。

pump01 同样，略过。
6， 数据初始化 expdp 通过flshback_scn , DG主库。
7， target 端启动：
GGSC > add replicat rep214, exttrail ./dirdat/e1, begin now
GGSCI > start replicat ,aftercsn 6553589

9， 完成。
