Why is my oracle RMAN backup failing with ndmp error

[DPO]

We have noticed that our RMAN DB backup has failed with following error. We are not using any NAS storage. This is just DB full backup.

That is weird yes, can you post bpbrm/bptm logs. And maybe bppllist "policy name" -L and the output of the scripts from the client.

I would like to see rman output file first of all.

it would seem that your site specific script is exiting with a hard coded status of 99. i suspect that the idea of an NDMP error is a red herring. We need to find out why the script is taking the pathway which results in it exiting with status 99. Are you able to share the script and its log? (be careful to review the code and not share any paswords with us).
