Description Lukas Krejci 2012-08-07 06:13:51 EDT
+++ This bug was initially created as a clone of Bug #837126 +++ Description of problem: If JBoss EAP server has become unstable due to OutOfMemoryError condition or other problem that prevents the JBoss AS 5 plug-in from obtaining a connection to the server/service, it is reported as DOWN and the shutdown operation invocation does not occur even when a script is used as the shutdown method. The result is that an unstable or runaway EAP server can not be shutdown from the JON management UI. Version-Release number of selected component (if applicable): 3.1.0 How reproducible: Always Actual results: If EAP resource is shown with availability of UNKNOWN or DOWN, the shutdown operation is not performed and the operation result is: The server is already shut down. Expected results: The shutdown operation should still be invoked regardless of the availability of the EAP resource. Additional info: This is due to theo rg.rhq.plugins.jbossas5.ApplicationServerOperationsDelegate.shutDown() first retrieving the availability of the resource and if DOWN is returned, the method is aborted. This prevent a custom shutdown script from performing a forced shutdown in the event the EAP server has become unresponsive (kill -2/kill -9). : http://git.fedorahosted.org/git?p=rhq/rhq.git;a=blob;f=modules/plugins/jboss-as-5/src/main/java/org/rhq/plugins/jbossas5/ApplicationServerOperationsDelegate.java;h=5ac0413999c735cbd4e688d19c4089bc3b484c6c;hb=refs/heads/release/jon3.1.x#l306 --- Additional comment from email@example.com on 2012-07-02 18:05:21 EDT --- This issue prevents an alert definition from performing a resource restart in the event that something bad happens in the resource. For example, if a user wants to auto-restart a production JBoss EAP server in the event that a resource limit is reached (OOME), this issue prevents the restart from being successful. --- Additional comment from firstname.lastname@example.org on 2012-08-02 22:00:05 EDT --- We should take a look at this and see if there are any repercussions from removing the avail check.
Comment 1 Lukas Krejci 2012-08-07 06:14:12 EDT
I think that it is safe to remove the avail check. It seems to be in place only to reduce the amount of work we're doing and I don't think it provides much value to the user. We do nothing and just display the message "The server is already shut down." if we find the avail to be down. I think users wouldn't be surprised to see some slightly more cryptic message from the actual script or JMX call failing if it tried to shutdown a stopped server.

Comment 3 Heiko W. Rupp 2013-09-01 06:04:44 EDT
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
