Testing multicast applications on a non-multicast network

Use this information to learn how to test IBM MQ Multicast applications locally instead of over a multicast network.

When developing or testing multicast applications you might not yet have a multicast enabled network. To run the application locally, we must edit the mqclient.ini file as shown in the following example: Edit the Interface parameter in the Multicast stanza of the MQ_DATA_PATH /mqclient.ini:

Multicast:
Interface       = 127.0.0.1

where MQ_DATA_PATH is the location of the IBM MQ data directory ( /var/mqm/mqclient.ini ).

The multicast transmissions now only use the local loopback adapter.
