Subject [jira] Commented: (DERBY-1387) Add JMX extensions to Derby
Date Fri, 28 Sep 2007 14:37:51 GMT

Rick Hillegas commented on DERBY-1387:
--------------------------------------

Bernt> In oder to be able to make the JMX-components comply with the Derby Authentication/Athorization
scheme: Implement and BootedDatabasesMBean which will hold a list of booted databases in the
system.

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

Bernt> On second thought. Making the Derby JMX automatically available in the MBean server
will make it impossible for the user to make some application with an embedded Derby db manageable
thorugh JMX without also making Derby manageable thorugh JMX. I would think that this "all
or nothing" granularity could be a problem for some applications.

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?
