Thanks Robert,
This is NetBackup 6.5 and Oracle 10.2.0.4.
I see the tapes as full in NB. I want to restore the RMAN backups to the
file system where I can catalog them there, but I do not see how to do that
because I cannot see the backups? I see regular backups, but Oracle seems to
be treating differently and NB doesn't let you see them. Does anyone have
experience with this? May have to reach out to NB with help on this one.
