Hello Mike,<br>
Both Hibernate and Cloudscape (derby) responsible people telling me
there should no problem with their product in combination with dual
processor or Hyperthreating. But in real live this combination is not
stable. Too bad, because this could be a great combination (both
complete Java and free software). To save time I switched to a native
database (Ingres) but now I have a lot of installation issues. The
problem is reproducible. Just start a Hibernate project in combination
with Cloudscape on a Hyperthreating platform and things will go wrong.
The only issue is who’s responsible for this… Another problem is the
fact that there are not a lot of Cloudscape users in the Hibernate
community because the database is missing some features, which are
needed by Hibernate. <br>

Mike Matrigali commented on DERBY-260:

Roland did you ever get any more information about this.  Should we close this as not a derby
issue,  or at least not reproducible?

    <pre wrap="">Hello,
I am using IBM Cloudscape Version 10.0 with Hibernate and it works great. But at the time
I was deploying my project on a target with a Hyperthreating CPU things went wrong (database
very unstable). It seems that Cloudscape is not functioning on multiprocessor or Hyperthreating
architectures. Has anyone some more information?
