Error description
When the USEDLQ channel attribute is altered on a cluster receiver channel, the value is not replicated across the cluster, and so is not reflected in the corresponding cluster queue manager objects. . Additional information and symptoms: As an example, a CLUSRCVR has USEDLQ(NO) set, but due to this bug, the auto-defined CLUSSDR still has USEDLQ(YES) as shown by the MQ command DISPLAY CLUSQMGR(*) CHANNEL(chlname) CLUSTER(clusname) USEDLQ . Because of this unexpected USEDLQ setting, messages go to the Dead Letter Queue ( DLQ ) unexpectedly.
