Issue

• In an Oracle RAC environment, a warning stating that a unique constraint has been violated is seen in the log file after a failover:

• We have a JDBC master-slave configuration for our AMQ 6.1 message broker. We see that the master suddenly went down and has thrown the error relating to unique constraint.
