Bernt M. Johnsen commented on DERBY-1387:
-----------------------------------------

Rick> I'm not sure I understand how this would work. Does this mean that administration
would only be possible on databases which have already been brought up by normal application
activity? 

Yes, in the current patch, that is the case.

Rick> What if I want to administer a database which has been taken down and has no connected
users?

We will also need a knob for enabling of mangement of  databases that have not been booted
or have been shut down.

Rick> Maybe we should only allow JMX management of Derby if authentication is turned on.
If we did that, would we need an extra JMX-enabling knob?

Interesting thought. But I hope to avoid the following scenario (at least in the normal use-cases):
Given that JMX authentication is turned on, the user has to 1) Authenticate to be allowed
access to the JMX ssystem, 2) Authenticate to be allowed to manage the Derby system and 3)
Authenticate again to be recognized as DB owner of a given database. In other words: Authenticate
3 times before being allowed to de something with a specific database through JMX.
