Hi all,

In news from the trenches, UCT has recently updated our production 2-6-x system to JDK 1.6, Tomcat 5.5.28 and mysql 5.1.41.

The only hitch we encountered was postem which failed under Tomcat 5.5.28. This has now been resolved by merging 


to the 2-6-x branch.

We also ran into a mysql bug in 5.1.36 on a test server, so if you're moving to 5.1, we'd suggest the very latest version.

As mysql 5.1 supports using the query cache with server-side prepared statements, we have also changed our connector configuration to use server-side prepared statements with these parameters:


Apparently this can be good for performance (and reduces network traffic slightly).

Happy holidays all.
