    Backup Server 'Unable to announce backup'

    jhannah Newbie

      I've been attempting to get a Live-Backup configuration deployed on two distinct servers.  I've been using the user guide and examples to assist with my configuration, however, I've run into a problem that I haven't been able to resolve.  With the attached configuration, my Live server starts up without any problems.  However, when I startup my Backup server, I get a warning stating "Unable to announce backup" with the following exception:

       

      12:19:04,612 WARN  [ClientSessionFactoryImpl] Tried 1 times to connect. Now giving up on reconnecting it.

      12:19:04,622 INFO  [AprLifecycleListener] The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/jboss/jboss-6.1.0.Final/bin/native/lib

      Has anyone else experience this issue?  If so, has a resolution been found?  If anyone could comment on my configuration files, I'd appreciate any insights that could be provided.

       

      Thanks,

            Adding host parameters (ie: <param key="host" value="ip_address"/>) into the connector and acceptor elements resolved the problem.  These don't exist within the examples as they are intended to be run on the same machine.
