Subject [jira] Commented: (DERBY-1387) Add JMX extensions to Derby
Date Wed, 26 Sep 2007 12:08:53 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12530426
] 

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

Usability issue: 

Instead of controlling whether JMX for Derby is enabled or not by derby properties and/or
command line options, this should be dependent on the availability of an MBean server. That
is, JMX MBeans for Derby will be generated and registered if ManagerFactory.getPlatformMBeanServer()
returns a non-null value. The Mbeans will not be available outside the VM unless the MBean
server is instructed to do so. For Sun's VM, this is done by setting a system property, e.g.
like -Dcom.sun.management.jmxremote

When this is done, an JMX compliant application (e.g. JConsole) may connect to the MBean server
if run on the same machine and from the same OS user as the VM is running. More properties
may be set, to enable connections from another machine, enable/disable ssl etc. See e.g. http://java.sun.com/docs/books/tutorial/jmx/remote/jconsole.html
