Title: RE: Why are SPFILEs binary anyway? (was RE: How to make SPFILE in

Of course you are right that no one should use it as the right way to change parameters.

I will admit playing with binary file some times is my idea of fun.  Hey, you never know,

you might learn something from it.  To see the data structure gives me idea of how things work.

And it might come in handy some day in a recovery situation.

 

Best regards

Questin is why do you want to mess with it? That's not exactly my idea of fun ...

I'd still use alter system, alter database commands to change whatever.

That's a good point.  Someone should try a binary editor instead,
like bvi and see what happens.

I wonder if it is something built into the file or something that vi (or
whatever editor you are using) does to the file when you save it.  I say
that because, if you edit the text part of an export file with vi, you get
an unusable file.  But the text part of an export file can be edited by
other means and it will work -- for example, by running it through a C or
Perl program and editing the stream as it flows through the program; and I
think, if the export file is not too big (< 2 gig I think ) emacs (with
certain options??) can be used.

The official word in the 9i new features class at the ivory tower in
Colorado Springs is that all the new features are wonderful, and you should
be using them.
