[jira] [Created] (QPID-7192) [Java Broker] BDB HA Virtual Host Node
does not restart successfully if JE environment has locally committed
transactions requiring rollback
Alex Rudyy created QPID-7192:
--------------------------------
Summary: [Java Broker] BDB HA Virtual Host Node does not restart successfully if JE environment has locally committed transactions requiring rollback
Key: QPID-7192
URL: https://issues.apache.org/jira/browse/QPID-7192
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: qpid-java-6.0, qpid-java-6.1
Reporter: Alex Rudyy
Start-up of BDB HA VHN fails in following scenario:
1) BDB HA VHN is stopped in MASTER role with the transactions committed only locally requiring rollback on next restart
2) Anew election is hold and new Master is elected by remaining group members
3) The node is activated after that. Local transactions are rolled back and JE Environment is restarting. During activation BDB HA VHN calls JE environment to get nodes in order to verify permitted nodes but that call fails as environment is restarting. ConnectionScopedRuntimeException is reported to the user and BDB HA VHN activation fails with setting state to ERROR. The environment restarts successfully but BDB HA VHN does not hear that as state change listener is not registered. The manual restart is required to recover.
An exception is reported like the one below:

Test MultiNodeTest.testInFlightTransactionsWhilstMajorityIsLost sporadically fails because of this issue.
If issue occur in production on Broker or VHN startup an operator intervention would be required. Affected VHN needs to be restarted manually either using REST API or Web Management Console.
