    Description

      Scenario

      • There is one EAP configured to use JDBC persistence storage.
      • Producer sends 300 messages to InQueue.
      • After that MDB is deployed. It sends messages from InQueue to OutQueue.
      • When half of the messages occurs in the OutQueue, network between EAP and database is failed.
      • Network is down for 16 minutes to cause closing of JDBC connection.
      • Then network is restored and EAP is restarted.
      • After the restart MDB continues in resending of messages from InQueue to OutQueue.
      • Test waits until all prepared transactions are resolved.
      • Receiver receives all messages from OutQueue.

      Expectation: Receiver receives all messages sent by producer.
      Reality: Receiver doesn't receive all messages sent by producer. Some of them are lost.

      Customer impact: If network between EAP and database fails, some messages may be lost.

      When EAP is started after the network was restored, I can see log messages [1] in server.log. These messages corresponds to lost messages.

      When I tracked the XA transactions of lost messages, last information I found was that transactions were successfully rollbacked.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-10295 Lost messages if JDBC store is disconnected

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
