oracle 11g RMAN：Active Database Duplication for standby database 创建dg 命令解读

继上篇如果没有正确配置，理解duplicate from active  dg 的 run 脚本，就会出现以下错误：

1：路径不存在：

Oracle instance shut down
connected to auxiliary database (not started)
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

2：主库配置参数无法转换到备库

duplicate from active dg 的 run 脚本 sfile 为完整配置可能导致的一些错误
