If I am correct, Kevin Grittner is writing a review of the code and the
testing methods. I think it would be wise to wait for the outcome of this.
Afterwards, I could post the code and the executi

A few updates from my side:
Kevin helped me find two bugs in my test suite. The first: the test suite
had a syntax error in setting the isolation level, which resulted in not
setting an isolation level at all. Secondly, I made a mistake in the phantom

wrong approach or mistake, I'll post it.

The report is based on a java application that can be found here:
http://dl.dropbox.com/u/19316575/dbtp.zip. This zip-file also includes an
SQL file that creates the used tables and the queries that are executed.
I put a README-file in the zip with installation instructions. Most easy to

That is a pretty old version. At least you should use the latest version
in the 8.3 series, which is currently 8.3.16. I'm not sure if there's
been any isolation-related bug fixes since 8.3.3, but I don't see any
reason not
