Is this true?  
I thought that if the transactions needed for recovery are in the online
redo logs, and the online logs are available, then the RECOVER DATABASE
statement will read from the online logs.  Just did it this morning on a
noarchivelog database, Oracle 7.3.3.  If however, the data needed for
recovery in the online logs has been overwritten, then the database will be
unrecoverable.
