Daniel John Debrunner commented on DERBY-3466:
----------------------------------------------

A simple initial scheme could be to have a system attribute for each MBean 
registered by Derby. The JMXManagamentService could automatically add this to 
the ObjectName when MBeans are registered with it. Initially a newly created 
UUID could be used as the system identifier. I have some code that does this, 
I'll submit a patch soon.

Future options could allow the application to provide a system identifier in 
derby.properties.


> Investigate ability to run multiple Derby systems in same JVM with different 
> sets of MBeans.

> One of the reasons for JMX was to move away from system properties 
> (specifically derby.system.home) to allow multiple Derby systems running 
> within the same virtual machine. It would be good to get some unique 
> naming/attribute scheme in the ObjectNames up front rather than only have it 
> in some later version.
