Hello,
This is with referance to your post on the error you receive during backup of Oracle. It seems that you are not using AOFO during the backup. Does the error occur only while you backup on the hp cassette library? What is the OS on the remote server? Did you check if the oracle agent is up and running during the backup? If the problem persists, you can answer to the above given questions in the post. However if it is resolved, do intimate us.
NOTE: If we do not receive your intimation within two business days, this post would be assumed answered and archived.
Regards.
