                 Key: DERBY-4807
                 URL: https://issues.apache.org/jira/browse/DERBY-4807
             Project: Derby
          Issue Type: Task
          Components: Test
    Affects Versions: 10.6.2.0, 10.6.2.1
         Environment: Windows XP, Windows 2003, Windows 2008, IBM JVM 1.6 (SR8), 1.5 (SR11)
and weme 6.2
            Reporter: Myrna van Lunteren


Setting up automated nightly test runs has been troublesome for 10.6 on windows because the
set of tests (derbyall/suitesall with 3 different jvms) that completed within a day on a machine
with similar hardware but running XP did not complete within a day on a machine running Windows
2008.
Switching to a machine with windows 2003 appeared to improve matters. Switching to a machine
with XP, and the test finished.

Initially, my focus has been to try to get the tests to run consistently, now I will be analyzing
this further.

I now have a separate machine that has the 3 OSs loaded on it, and will experiment, and gather
data, using the 10.6.2 jars so the only difference is the OS.
