Question

An EJB application posts a request message into a JMS destination and waits for a response message on a different JMS destination. To correlate the response message to the request message, the application uses the JMS correlationld of the message. The application waits up to five seconds for a response before timing out the request. A Message Driven Bean (MDB) running on a different cluster is responsible for consuming the request message, process it and post a response message. The destinations are defined in a Service Integration Bus (SIB) within the cell. Intermittent timeout exceptions have occurred for the requester application. How can a system administrator correlate and analyze the debug information from both requester and consumer applications?

Options

  • AEnable High Performance Extensible Logging (HPEL).
  • BEnable a diagnostic trace in both requester and consumer servers.
  • CEnable High Performance Extensible Logging (HPEL).
