Just ran into this one yesterday. Definitely DID restore *ALL*
datafiles, yet ran into the error above.
No logical explanation. Managed to get around it (error moved to the
rollback tablespace), files seemed to have change timestamps (original
'backup' was made with cp (without switches) controlfiles copied last.
Is there any explanation for this.
Also can only shutdown this instance (8.1.5.0.0 on solaris ) by using
abort. There seems to be an application process which is constantly
polling the database, and thus creating havoc.
