Hi,all
I hava an app which runs on JBoss 4.* with the JNDI connection datasource pooling named
testDs,and sometimes it does not work.At that time I view the
"jboss.system"-"type=ServerInfo" in jmx-console,invoke the
"java.lang.String listThreadDump()" operation button and find there are several
BLOCKING state threads which indicate they are blocking in getting datasource connection.
In the meantime,i try to view
"jboss.jca"-"name=testDs,service=ManagedConnectionPool" in
jmx-console,but find there is no response when i click that link,which means i could't
access the attribute page for the testDs connection pooling.When i restart the JBoss,it
works.Anybody knows how this happened? What lead to the connnection pooling attribute page
can't be accessible?
Your reply will by most appreciated.
