Setting up communication on UNIX and Linux systems

DQM is a remote queuing facility for IBM® MQ. It provides channel control programs for the queue manager which form the interface to communication links, controllable by the system operator. The channel definitions held by distributed-queuing management use these connections.

When a distributed-queuing management channel is started, it tries to use the connection specified in the channel definition. To succeed, it is necessary for the connection to be defined and available. This section explains how to do this. You might also find it helpful to refer to the following sections:

For Windows, see Setting up communication for Windows.

You can choose between two forms of communication for IBM MQ on UNIX and Linux systems:

Each channel definition must specify one only as the transmission protocol (Transport Type) attribute. One or more protocols can be used by a queue manager.

For IBM MQ MQI clients, it might be useful to have alternative channels using different transmission protocols. For more information about IBM MQ MQI clients, see Overview of IBM MQ MQI clients.
