One thing to consider is country codes. I have seen many applications
where two character country codes have been crammed into the STATE_CDS

but that means that some smaller countries end up with abbreviations that

Create a view where you select the case-insensitive columns with

I'm assuming that you're creating a 9i database on the new machine when you
install Oracle.
I find it useful to pre-create the tablespaces (and users) on the new
database, rather than let the import do that. This gives you more control
over where datafiles end up and do some clearup on
Not an easy question.
Set up a folder (directory) on the NT server called STUDENTS. Set your
utl_file_dir parameter to that folder. From the server's SERVICES panel,
stop and start the instance (so the parameter will take effect). Under
STUDENTS, create folders for each of your students and

I think that he has a much more serious problem than setting the SID. If I
understand the situation the Oracle Service (the instance) is not starting
because the ORACLE_HOME parameter in the registry is messed up (probably as
part of the upgrade).

instance and mount the database. You should not see this message.

I try to keep the total SGAs of all instances below 50% of RAM for Windowz

The best argument is that you have the hardware and software on-site for

It's not a failover situation but it does mean that production would be
down for hours instead of days.
Reduce the number of DB_BUFFERS. Unless my eyes deceive me, if you have a
2k block size, then you're trying to allocate 1.2G of SGA just for the
DB_BUFFERS.
On an Intel system (I assume W2K), I wouldn't try to allocate more than 1/2
the physical RAM for the total SGA. Windows will still swap

My bad. I didn't notice that he was doing a select * from v$sga and
thought that it was the init.ora parameters.
My comments on the SGA size were based on WinNT 4.0. I assume, from your
comments, that W2K is better about not swapping the RAM out to disk.
I need to compare identical databases across two instances. I've set up
a MID instance to do the heavy lifting and not impact our production. But
this particular form of querying via link A with a sub-query via link B
kills the session.

Other than that, temporary files, downloads, system swap space -- things

I'm going to be installing Oracle 7.3.4 and 8.1.6 on the same Win2K server
shortly. The 7.3.4 is so that we have an accurate version of the old
database which is being migrated to 8.1.6 (which explains the 8.1.6).
I'll be putting them in different ORACLE_HOMEs and installing 7.3.4 before
8.1.6.
I don't think that size has much to do with it. You can have lots of data
but if it's all in a few tables then it doesn't qualify as a datawarehouse
(IMHO).
My short take on this is that a datawarehouse is a OLTP database with
de-normalized data that supports a DSS application.

I'm not sure that I understand the question. Is it:
