I found a db in an unrecoverable state this morning. An incremental 0
ran in the wee hours while I dreamed of being in an iron man movie or
some such, but this morning I find:
RMAN> report unrecoverable;

Maybe "validation complete" doesn't mean all is well?
How can a level 0 with all the redo available get into a state where
datafiles are unrecoverable? Thanks.
