The issue with startup with the EM has a good lead from looking at the logs.
It looks like an & for some query in realms.xml is having issues on line 90. It may need to be in quotes.
Introscope Enterprise Manager failed to start because:
INFO | jvm 1 | An error occurred while trying to start Isengard.
INFO | jvm 1 | XML Error Configuring User Management Service: The entity name must immediately follow the '&' in the entity reference.
INFO | jvm 1 | 2| The entity name must immediately follow the '&' in the entity reference.
What should I do to resolve this?
