could not find stateful bean errors (passivation issues)
--------------------------------------------------------
Key: NXP-1545
URL: http://jira.nuxeo.org/browse/NXP-1545
Project: Nuxeo Enterprise Platform 5
Issue Type: Bug
Components: Web Foundations, Web UI
Affects Versions: 5.1.0.GA
Reporter: Olivier Grisel
Assignee: Thierry Delprat
Fix For: 5.1.1
The current state of platform has still issues with a number of a Stateful bean
that fail to get restored after passivation. Here is a procedure to hunt them:
- set up the threshold of the logs for appender File (
server/default/conf/log/log4j.xml ) to level DEBUG after having used the
current version of "ant patch" to enable the logging of DEBUG level EJB3
serializer:
<category name="org.jboss.ejb3"><priority value="INFO"/></category>
<category
name="org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager"><priority
value="DEBUG"/></category>
- adjust the serializer to passivate beans more often than on a real
production setup using the idleTimeoutSeconds parameter of the file
server/default/deploy/ejb3-interceptors-aop.xml, for instance :
<annotation expr="!class(@org.jboss.annotation.ejb.cache.simple.CacheConfig)
AND !class(@org.jboss.annotation.ejb.Clustered)">
@org.jboss.annotation.ejb.cache.simple.CacheConfig (maxSize=100000,
idleTimeoutSeconds=300)
</annotation>
Then run the application with and play around for a couple of minutes (import
files, use the clipboard, the workflow, ...), then wait a couple of minute and
then play again. You should get a couple of 404 errors though most passivation
errors are logged silently without user level crash screen.
Then run the find_passivation_errors.py python script to analyse the log
automatically:
https://svn.nuxeo.org/nuxeo/tools/jboss/find_passivation_errors.py
Here is the output of the script after a 10min test run with 2 users playing
around:
