RMAN-06172: no autobackup found or specified
handle is not a valid copy or piece
Answer: The docs note
this for the ORA-06172 error resolution:
RMAN-06172: No autobackup found or
specified handle is not a valid copy or piece
Cause: A restore could not
proceed because no autobackup was found or the specified handle is
not a valid copy or backup piece.
In case of restore from
autobackup, it may be the case that a backup exists, but it does not
satisfy the criteria specified in the user’s restore operands.
In case of restore from handle, it may be the handle is not a
backup piece or controlfile copy. It may be that it does not exist.
Action: Modify autobackup search
criteria or verify the handle.
