Hi Andrew,
I wanted to mention that OpenBase 11 addresses one issue related to deadlocks and WebObjects. We had a reproducible case and were able to isolate the problem and fix it for this upcoming release.
If you try the beta, here is a license which will enable the software: SN: OBWEBCDEVBETA-629 Authorization: D-2009.01.15-1000-11.0-04F-639-5A1
Finally, I want to also let everyone know that we have an OpenBase v11 64 bit build we are working on. The big advantage of 64 bit as it relates to scaling is that the OpenBase server is no longer limited to a 3.5GB memory footprint. That means we can make better use of available memory to provide faster performance. We will have details in January on how you can get your hands on an early copy of that, but I wanted to let you know that it is coming.
Best regards,
Scott Keith OpenBase

Hello Joe;In high-volume concurrent situations, there is an issue with EOF together with OPENBASE where concurrent transactions can get into a deadlock when writing into the same series of tables. Let me be very clear; not a problem with OPENBASE per se, but a specific problem with EOF and OPENBASE. To avoid this, I have created a simple subclass of the JDBC Adaptor (distributed in a self-contained Framework jar) specifically to address this issue. To find out more about this read the LEWOStuff PDF under; 9) OPENBASE JDBC Adaptorcheers.Does anyone have any real world, recent, experience with OpenBase on a large scale?
