Subject [jira] [Closed] (UIMA-5136) UIMA-AS: the undeploy removes all MBeans from JMX
Date Thu, 27 Oct 2016 16:20:58 GMT

     [ https://issues.apache.org/jira/browse/UIMA-5136?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jerry Cwiklik closed UIMA-5136.
-------------------------------
    Resolution: Fixed

Segregated each pipeline into its own hierarchy in JMX. Modified code to use deployment specific
registry for MBeans. This provides a way to manage pipeline specific MBeans. When a specific
pipeline is undeployed it is now easy to remove related MBeans from the JMX registry without
effecting other pipelines

> If there are multiple pipelines deployed in the same process, an undeploy of one of them
causes all MBeans to be removed. The remaining pipeline's statistics are destroyed in the
middle of processing. 
> The code in question is:
> Line 138 -140 in org.apache.uima.aae.jmx.JmxManager
> public void destroy() throws Exception {
> unregisterDomainObjects("org.apache.uima:type=ee.jms.services,*");
> }
> The undeploy should only remove MBeans related to a pipeline being undeployed.
