Hi Mladen,
Oh, I have no doubts ;)
Hurt you still don't trust me but considering our little wager (2 tickets to
the Bowie world tour) I guess it's only fair you go to a neutral referee.
Bet when they confirm what I say they don't give as detailed an explanation

Title: Howto drop a corrupt database ?
Hi,
I'm running Oracle 8.0.4 on AIX: for one of the databases, my datafiles got corrupted and I got NO BACKUP (and NOARCHIVELOG) :(
SVRMGR alter database open;
ORA-01122: database file 6 failed verification check
ORA-01110: data file 6:
Hi Gorik,
Do you want to drop the database as a whole, i.e. including your system
tablespace etc?
Just delete all your controlfiles, datafiles and redologfiles, keep the
initSID.ora and start creating the database all over again. (You
do have a create-script, don't you?).
Of course you can

Nice thoughts Mogens. I just read an article in a Dutch magazine which

I had the same thought, also thought that
if you have something like this that does not get executed:
if VAR1 like '%abcbdbdbbbfdbfdfdfd%'
The compiler (or the semi-compiler) still has to allocate memory for VAR1
and load it.
I'm testing and will update the list, if I managed to find anything!
Yechiel's idea reminds me of one of that 'tuning tips' of old which said
'avoid calling a routine too far away in the code' (because it could be
in another page, etc.). This kind of phenomenon, reference to chunks of
code which have been safely parked away on disk may also come into play.

If no gaps are allowed, you probably should allocate a key value for any
