[Info-Ingres] Questions about INGRES II 2.6 Environment

[Eduardo Klein]

Hi all.

Let me explain my scenario and make some questions.

I'm working in a project that will develop a solution that needs 
integration with a legacy system: An INGRES II 2.6 database in a AIX 4.3 
server. Also it is strongly suggested that I use CA-ODBC 3.50 to access 
it from my solution (A set of .NET web sites, applications and modules).

I'd like to reproduce my customer's environment in my development center.

First of all, I was think about using a Windows version of INGRES in 
order to dismiss the use of an AIX server. Any problems? I thought that, 
as I just need to communicate with INGRES using standard ODBC, it 
wouldn't be a problem.

When I visited INGRES web site, I found out that the only version 
available for download is INGRES 2006. Is this a newer version of INGRES 
II? I have no idea of how old INGRES II 2.6 is... Do you know any site 
where I can find this version?

After installing the 2006 version, I could notice that its real version 
is 9.0.4.105. So it sounds to me that 2.6 is a lot older.... Isn't it?
I also looked at ODBC Panel, in System Tools, and found an Ingres entry, 
that points to CAIIOD35.dll. Is this the version I need (CA-ODBC 3.5) or 
just a coincidence?

Nowadays, I would expect that there is a .NET Managed Provider for 
INGRES... Does this exist? Or ODBC is the best choice, from a .NET 
perspective? With good points, I could convince my customer to let the 
use of a .NET Provider.

I know that it's a lot of questions. I'll be really grateful for any 
help. Forgive me from my poor english. :-)

Thanks a lot,
Eduardo Klein
