Assign additional processing threads to enable processing of timed out aggregation messages in the AggregateReply node.
By default the AggregateReply node uses a single thread to process timed out aggregation messages. In scenarios where a high volume of messages are expected to timeout, a backlog of messages can accumulate on the SYSTEM.BROKER.AGGR.QueuePrefix.TIMEOUT queue. Follow this task to assign additional processing threads for timeout processing in the AggregateReply node.
mqsichangeproperties MYBROKER -c Aggregation -o myAggregationService -n timeoutThreads -v 10
This
command sets the timeout threads of an aggregation to 10 for all nodes
that are configured to use the myAggregationService configurable service.
