Hi John Thanks for your speedy response. I've tested the suggestion in bug 454.... "This can be deactivated via com.ibm.as400.access.AS400JDBCDataSource if you call the method setTcpNoDelay (true)" This did the trick in our sample app. Our framework pools the connections and doesn't allow easy access to the underlying implementation so we'll wait for your upcoming release with new JDBC connection property Thanks
