Simple Query problem

Question

Hi all,

Answer 1

Pike,
I believe that the problem has to do with an esoteric DB2 JDBC driver
issue to do with how we handle pooling.
If you set the MaxPool to some value greater than 0, I believe that
everything will work as expected.

Hi Patrick,
The contents of the kodo properties is:
# Kodo JDO Properties configuration
com.solarmetric.kodo.LicenseKey=KEY
com.solarmetric.kodo.ee.ManagedRuntimeProperties=TransactionManagerName=java:/TransactionManager
javax.jdo.PersistenceManagerFactoryClass=com.solarmetric.kodo.impl.jdbc.JDBCPersistenceManagerFactory
javax.jdo.option.ConnectionDriverName=com.ibm.db2.jcc.DB2Driver
javax.jdo.option.ConnectionUserName=USERNAME
javax.jdo.option.ConnectionPassword=PASSWORD
javax.jdo.option.ConnectionURL=jdbc:db2://HOST:PORT/DATABASE
javax.jdo.option.Optimistic=true
javax.jdo.option.RetainValues=true
javax.jdo.option.NontransactionalRead=true
# Changing these to a non-zero value will dramatically increase
# performance, but will cause in-memory databases such as Hypersonic
# SQL to never exit when your main() method exits, as the pooled
# connections in the in-memory database will cause a daemon thread to
# remain running.
javax.jdo.option.MinPool=0
javax.jdo.option.MaxPool=0
and my contents of the getPM() method is
     public StandaloneJDODemo() throws IOException {
          Properties props = new Properties ();
          props.load (getClass ().getResourceAsStream ("kodo.properties"));
          pmf = JDOHelper.getPersistenceManagerFactory (props);
     private PersistenceManager getPM ()
          PersistenceManager pm = pmf.getPersistenceManager ();
          return pm;
thanks,
pike

Pike,
Can you post the properties that you're using to create your PMF, and
the contents of the getPM() method?
