Subject [jira] Commented: (DERBY-1387) Add JMX extensions to Derby
Date Fri, 01 Feb 2008 16:01:30 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12564808#action_12564808
] 

Daniel John Debrunner commented on DERBY-1387:
----------------------------------------------

Thanks for the updated specification: Some initial questions:

1) Is a derby.system.jmx needed? What would be the downside of always having the jmx beans
available, or available if the jvm has jmx running?
This may depend on security issues, I haven't looked at that in detail yet.

2) In the "Enabling Management Features" section, are the com.sun properties standard JMX,
or are they specific to Sun's implementation of the JVM? useful to state this in the specification,
so that any user documentation reflects reality.

3) The spec says that classes in org.apache.derby.impl.services.mbeans. will be added to the
public api. The 'org.apache.derby.impl.' set of packages is for implementations of internal
apis (o.a.d.iapi). If these classes are external then they need to be moved to a new package.
o.a.d.jmx?
As a minor point I wouldn't have Derby in the name of these classes.
