On UNIX systems, broker parameters are controlled by the Broker stanza of the queue manager configuration file, qm.ini. Figure 21 shows an example of this stanza. On Windows, you can view and update these settings using the Broker page of the queue manager properties in WebSphere MQ Explorer.
The parameters are described in Broker configuration parameters.
