Rhq server 4.6.0 cannot scan plugins

[lzmuda]

Hi,

when I've upgraded Rhq server from version 4.5.1 to version 4.6.0, I've got error as follows:

14:21:50,641 ERROR [org.rhq.enterprise.server.core.plugin.PluginDeploymentScanner] (EJB default - 1) Scan failed. Cause: java.lang.ClassNotFoundException:org.rhq.enterprise.server.xmlschema.generated.serverplugin.perspective.PerspectivePluginDescriptorType from [Module "deployment.rhq.ear.rhq-enterprise-server-ejb3.jar:main" from Service Module Loader].

When I'am in Administraction->Configuration->Agent Plugins section and I use button "Scan For Updates" I see error:

14:45:35,940 ERROR [org.rhq.enterprise.server.core.StartupBean] (EJB default - 7) Plugin scan failed. Cause: java.lang.ClassNotFoundException:org.rhq.enterprise.server.xmlschema.generated.serverplugin.perspective.PerspectivePluginDescriptorType from [Module "deployment.rhq.ear.rhq-enterprise-server-ejb3.jar:main" from Service Module Loader].

So, I have version 4.6.0, but all plugins are comming from earlier version.

Thanks for your help,

Lukasz

The perspectives plugin is (was) a deprecated server side plugin that is no longer part of the server distribution. It has been removed.

Sounds like your upgrade was corrupted somehow. You should not be seeing this error since that plugin has been removed entirely from 4.6.0. You might want to review your upgrade steps to make sure you following them properly and look at the installer logs to make sure you didn't get any errors during the upgrade. Because I can see in our db-upgrade script the perspective plugin should have been completely removed:

            <!-- The perspective server plugin type has been removed - delete perspective plugin from DB -->

...

<schemaSpec version="2.128">

                       DELETE FROM RHQ_PLUGIN WHERE NAME = 'CorePerspective'

...

So that tells me your database was not upgraded. Something happened during your upgrade procedures.

My initial guess is that you copied all your server-side plugins from your old 4.5 install and put them in your new 4.6 install's /plugins directory.

If that is what you did, go into the Adminsitration>Server Plugins page and delete the plugins that are no longer in 4.6 (just do a compare between a 4.5.1 and 4.6 install - one for sure that went away from the perspectives plugin - I am not sure what others went away. Not much more than that one I think.

Thanks for your reply.

I didn't copied any plugins.

My database isn't upgraded, in table RHQ_PLUGINS,  in column "version" I have 4.5.1...

In rhq-installer.log I've found only one error

14:19:10,540 ERROR [org.jboss.remoting.remote.connection] JBREM000200: Remote connection failed: java.io.IOException: JBREM000202: Abrupt close on Remoting connection 0054777e to localhost/127.0.0.1:6999

something really bad happened. Don't know what. You should attach your logs/rhq-installer.log file.

I'll assume you followed the new installation procedures (they are much different in 4.6 from 4.5) - https://docs.jboss.org/author/display/RHQ/Running+The+Installer

Of course, I know all new procedures, I hope I did everything as I should. Here is my rhq-installer.log file.

On the surface, that all looks right to me.

I don't know why your perspective plugin is still around. It should have been removed during your oracle schema upgrade that happens early on in the install. That indicates to me something did not work right or something was misconfigured, but I can't say. I would keep an eye out for further issues - because I suspect your 4.6 install isn't 100% correct right now. Look in all your log files and perhaps you can see some errors that look like it might point the way to the source of the problem.

Keep in mind that you can remove plugins from the Administration plugin pages :

I deleted manualy row with name 'CorePerspective' from table RHQ_PLUGIN in my database and now it seems to be working correctly. Maybe it's not the best solution, but it works. Thanks for your patience.
