As an UNIX/Oracle DBA, I recently had the opportunity to make a COPY of an Oracle database (8.0.5) in NT environ.
I investigated "ORADIM80" and shutdown the database to be copied. Then I made a copy of the directory (folder). From this point I ran through my usual cloning routine; renaming files, editing the copy-init.ora, edit the trace file of the ".. backup controlfile to trace.." etc.
I cannot OPEN the clone! Oracle server want to "recover"
the system tablespace's datafile. It also want to apply
archive logs (the original is not in archive mode).
