[jboss-user] [Messaging, JMS & JBossMQ] - Re: No pong received warning

[dgusoft]

Hi!

FAQ is found under:

http://wiki.jboss.org/wiki/Wiki.jsp?page=IGetIOExceptionPingTimeoutHowDoIFixIt

We have similar Exceptions here with JBoss 4.2.1 GA. At the moment our oracle database isn't available for about an hour each night. We have no client using JMS. All happens on the server side.

The following exceptions can be found in the jboss.log:

01:52:43,313 WARN  [Connection] Connection failure, use javax.jms.Connection.setExceptionListener() to handle this error and reconnect
org.jboss.mq.SpyJMSException: No pong received; - nested throwable: (java.io.IOException: ping timeout.)

Even though the database is back online for a couple of hours the exceptions only disappear when jboss is restarted.

The FAQ only says :

 I'm inside the application server, how do I install the exception listener?

    * You don't need to for an MDB, JBoss does it for you. 

This doesn't seem to be true in every case.

Any hints?

Thanks in advance
