The following error is reported trying to create a Physical Standby database using "duplicate from active database" : RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of Duplicate Db command at 05/10/2015 19:54:23 RMAN-03015: error occurred in stored script. Memory Script RMAN-03009: failure of backup command on disk1 channel at 05/10/2015 19:54:23 ORA-17628: Oracle error 19505 returned by remote Oracle server
问题处理：
最初是以为db_file_name_convert参数设置有问题，但是详细验证后，并没有发现问题。
最后发现，在standby库中在创建对应目录stdby的时候，手误写成了stdy
重新创建正确的目录后，再执行duplicate命令时，执行成功。
duplicate命令创建physical standby数据库报RMAN-03015 ORA-17628
