Oracle Data Providers (Connection Pooling & Transactions)

I want to connect to Oracle 8.1.7 server through my application. I would
like to know which .NET data provider will be the best option? Microsoft
Oracle Provider or a ODP.NET provided by Oracle.

Here server is hosting databases for many other applications and
performace is a big issue. So I want to choose a provider which will
give the best performance.

I also want to make use of connection pooling. Do I need to do some
specific setting for enabelling connection pooling using these
providers?

Also, do I need to use COM+ for supporting distributed transactions
while using any of the above 2 providers?

thanks in advance.
 
Prits -

ODP.NET can do distributed transactions using Enterprise Services. I might
be wrong about it, but I don't think System.Data.OracleClient can (Just
write up a quick example and find out). Also, ODP.NET can do cool stuff like
SavePoints - which OracleClient cannot do.

BUT

Distributed Transactions using ES are a pain in the butt - are you sure you
need them? I mean, there are other ways to skin the same cat - what exactly
are you trying to acheive?

And Savepoints really can be done by direct execution of OracleCommand in
OracleClient - why not just stick with a wholly microsoft solution, and know
that it's done right? (I just feel nervous loaning the heart of my
application to Larry Ellison).

ODP.NET requires the 9i client or higher, so you will probably need to use the Microsoft .NET
Provider for Oracle instead if you're using 8.1.7.
