Problem

When attempting to run 'datamover ui' (for example to reset the admin password) you will receive an unable to connect. The logs will not show you what you would expect.

-The reason is that the Activator Derby database has been moved.

Resolution

Open up the /activator/bin/environment configuration file and find the section 'rem Standard parameters'. In this section is a parameter '-Dderber.system.home=..'

Change from this:

-Dderby.system.home=..\corelib\db\derby

To this:

-Dderby.system.home=..\derby

Attempt to run the /activator/tools/datamover utility again. The test button should work as well as any other commands from Support that you have been given instructions for.
