Login is possible if Enterprise Manager is configured to use file-based authentication (users.xml)

Does not affect Enterprise Manager running on other platforms such as Linux or Windows

Environment

APM 10.5.1 running on AIXConfigured to use EEM for authentication/authorization, EEM could be running on any platform.

Cause

The Enterprise Manager is an OSGi application which changes the way that classes are loaded and the required 3rd party library cannot be found.

Suspicion is use of IBM JRE which is delivered with the Enterprise Manager running on AIX is having an impact on class loading.

Resolution

We can add a property to allow all code to be loaded by the main JVM class loader so that the class is found.

To do that:

!) Open the Introscope_Enterprise_Manager.lax file in the root of the Enterprise Manager installation.

2) Find the property lax.nl.java.option.additional

3) Append the following value

-Dorg.osgi.framework.bootdelegation=*

4) Restart the Enterprise Manager

Additional Information

Note, we are still investigating a more precise solution but -Dorg.osgi.framework.bootdelegation=org.w3c.dom or -Dorg.osgi.framework.bootdelegation=org.w3c.dom.* do not work.
