free email such as gmail.google.co m, or use groups.google.c om

I s'pose the might be a legit reason, but ...

That's why I was hoping to hear from people who had used both Oracle and DB2

information by the vendor always tends to be skewed in some way that is
favourable to the vendor but not necessarily a fair way.

So what exactly is the value given by people in the DB2 usenet group
saying "We're best" while the people in the Oracle usenet groups say
"We're best"?

Or do you think you or your imaginary friend are in any position to
evaluate the values of shared-everything vs shared-nothing? How about
the value of procedure code compilation options? Bulk collection?
Multi-version read consistency? Do you really think there is any value
there based on your set-up?

I don't!

I have an associate that always knows exactly which product to
recommend. The one where he makes the greatest commission. Oh but
then he sells life insurance. ;-)

I am still far from convinced your question is sincere.

But if it is the nonsense about a friend that is so wholly uneducated he
couldn't handle a stack of 3x5 cards is preposterous on its face.

So if you are serious ... ask serious questions. Do you think a hammer
is the best tool for assembling a precision watch? Do you think a
microscope appropriate for putting the propeller on an aircraft carrier?
You give an exact description of the need and someone might think you
seriously trying for something other than a flame war.

Re: Comparison of DB2 and Oracle?

I used Ingres for 15 years
I have now used Oracle for 1 year
I am doing the same work now that I did on Ingres, except Oracle costs
a lot of money, and Ingres is free.

You can download Ingres from www.ca.com and give it a test.

Scott just
want some honest facts to help him decide which product is best at which

Scott needs to read more about both products. And
learn more about IT, particularly databases.
Instead of hoping a Usenet discussion

He is rather new to systems work - I think he is just out of school - and he
doesn't had much contact with databases yet. He has heard names like Oracle

suggested he post here and on the Oracle newsgroup but he doesn't have

Please see my reply to DA Morgan where I explained Scott's situation in a
bit more detail. The fact is his employer doesn't allow newsgroup access at
work - I've encountered other (foolish) employers who followed the same
policy - and he plans to get newwgroup access at home but is in the middle
of a move to a new house right now. He will get newsgroup access in a few
weeks once he's settled in his new house. *I* told him about Google's
newsgroup reading capabilities so that he could read these replies from his
browser; I don't think he knew about Google newsgroup archives before.

Since none of that is relevant to the question at hand, I omitted it from
the post. Besides, what possible benefit could I get from making him up?? I
was simply trying to explain that I was asking a question for a friend who
had such-and-such a level of understanding of database. Period.

Now, do you have anything useful to contribute to the discussion?

Nobody's looking for a free ride. He/we just wanted to hear from people who
had used BOTH products to see what their pros and cons were. He/we also
wanted recommendations about good independent sources of reviews of these
products. That's exactly what I asked for.

Re: Comparison of DB2 and Oracle?

Rhino,

There is no way to discuss pros and cons of DB2 and Oracle in a
constructive way (i.e. in a way that would provide value to the
customer) without going back to specific customer requirements, which
you are telling us that he doesn't have. There just isn't a good answer.
The first thing he needs to learn to be a successful consultant is that
EVERYTHING begins with customer requirements. It's kinda like going car
shopping and asking the dealers to compare a Nissan Altima with a Honda
Accord. You need to know certain things about how you're going to use
the car to make heads or tails of what they are going to tell you.

I liked Oracle better because the concurrency model is much nicer. I found
that you had to run DB2 in autocommit mode if you used dynamic SQL because
of page locks on the plan table. Never had to worry about that in Oracle.
That doesn't really tell you much. It would be much better if you actually
did some work and said what your business needs.

Perhaps rather than doing on Oracle what you used to do on Ingres you
should try leveraging what Oracle can do and do things differently.

Your statement is roughly equivalent to ... I used to build houses

Had you said 15 years of Ingres and 1 year of DB2 or Informix or 3x5
