Inter-broker communications parameter values (collectives)

Select the properties and values that you want to change for inter-broker communications for brokers that you have configured in collectives.

To change these properties, you must specify the broker name and -e with the name of an execution group. You must also specify DynamicSubscriptionEngine for the ObjectName.

The following properties and values are valid for execution groups for brokers that you have configured in collectives:

-n brokerInputQueues
Specifies the maximum number of dispatch queues which are to be used when processing messages from an interbroker connection. Increasing the value might increase the rate at which messages can be transmitted across an interbroker connection:
  • Value type - integer
  • Initial value - 1
-n brokerInputQueueLength
Defines the maximum number of messages that can be stored in each input queue; the higher the value, the higher the number of input messages that can be stored in each input queue. However, the higher the value of this property, the larger the amount of memory that the broker requires for each queue:
  • Value type - integer
  • Initial value - 99

See the mqsichangeproperties command for examples of how to change parameters for brokers in collectives.
