Overview

This page provides information on troubleshooting Universal Enterprises Controller (UEC).

Java Under Windows

Java Compatibility

The Universal Enterprise Controller Client Applications have been tested and verified with Sun Java Runtime versions 1.5.

Known Problems

Java Upgrade Problems

There have been various problems reported, when installing one version of Sun's Java over another, that will cause some Java applications to work incorrectly. Un-install the original version of the JVM and install the new version. A fresh install will usually resolve these issues.

Java Under Linux

Java Compatibility

The Universal Enterprise Controller Client Applications have been tested and verified with Sun Java Runtime versions 1.5.

Known Problems

Wrong Window/Dialog Sizes Under KDE

The main window and dialogs may display at the incorrect sizes when using Java version 1.3.1 from Sun and the KDE window manager. Upgrading to Java version 1.4.1 or using another window manager (such as Gnome) will solve this problem.

UEC Problems

UEC Incorrectly Reports a Universal Broker as Unreachable

UEC uses the Universal Query protocol to poll the Universal Brokers in its list.

Universal Broker versions earlier than 2.1 (or 1.2 with PTF 5 on the AS/400) do not support this protocol; they will appear to be unreachable by UEC.

If a Universal Broker being reported – incorrectly – as unreachable is of the proper version, ensure that:

Address and port have been entered correctly
TCP connection can be made from the machine running UEC to the machine with the incorrectly reported Broker.

Universal Query can be used to verify the connection. If you can query the Broker using Universal Query from the machine on which UEC is running, UEC should be able to poll the Broker.
