Re: More spfile goodness

Parameter information isn't "control" information. Parameters are just input only, control information is read and updated constantly. The fact that the database can now update the SPFILE here and there still isn't quite the same thing.

Putting everything in one file would doubtlessly create some kind of "chicken-and-egg" problem during recovery situations, resulting in the elimination of NOMOUNT mode?

I haven't been following this thread, so I don't know if this has already been mentioned, but Oracle is simply enabling more and more control of the database structure from the "SQL>" command prompt. Unless you look at things from the perspective of never opening an OS command prompt and managing everything from OEM, then features like "Oracle managed files", DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES, and SPFILEs make no sense at all. Hence, the greatest resistance to these features comes from dinosaurs (like me) who have never touched OEM except to install it for someone else, because there is no benefit (except for the DROP TABLESPACE command!)...

It just so happens that SPFILEs appear to be a particularly ill-considered implementation of that goal. Try again, Oracle! The XML idea seems like a good suggestion...

<Slightly OT>
In my opinion, Oracle is intent on eliminating the OS "middleware" on database servers, positioning Oracle Enterprise Manager more true to its name. The current embracing of Linux isn't so much an endorsement of Linux's superiority over other OS's (because it isn't -- except for Windows), but rather Oracle taking yet another step toward eliminating the OS down to its basest essentials. The fact that Linux works so well and is so economical just makes the decision more popular. If Linus Thorvald or someone else had instead written a popular freeware OS based on CP-M or MULTICS, Oracle could've cared less and would have moved toward it anyway. Luckily though, we have Linux...

Just my $0.02...
