Question

This is my first time at dataguard. I've laid all the pipework and trying to perform duplicate target database for standby dorecover. I have ASM configured on both nodes. I have the backup location mounted on nodes. I am getting this error and wondering if it has something to do with ASM -- any thoughts? The backup set exists and I can see it from both nodes.

Hi, the backup files must be accessible by both servers ( primary and standby) in the same location, you must ensure that and try again.
Also you can review the Note:248382.1 into metalink site.
Luck.
Have a good day.
Regards.
