Before putting Ingres R3 into production please make sure you can get support for it.
We went live on a major implementation using zope 2.7.3 ZEO and Ingres R3 (int109) on RedHat AS 3.0 for a large customer (TPA with 200,000 lives)
It has been a nightmare. The memory leaks in the ingres Python DBI are just the beginning. We fixed a few and submitted patches
On the DB server
we see the following in the log file
Memory corruption errors

iowait hits 100 % and  system comes to a grinding stop.

It could be our code (which worked well on postgres) but I am inclined to think its not the main cause

We of course contacted CA for support and spent 4 days to learn that they are just getting the system in to take support calls and sell support on R3.
The last time we had an issue with postgres a guy from command prompt inc logged in within 30 minutes and fixed our problem.

Since Ingres Plone and APE have some things in common I thought I should post this on this forum. Your experience may be different and
the above is just FYI . I hope things get better in the days ahead.
