Different types of bindings IBM MQ supports two ways that an application can connect: 1. Local bindings : This is when the application and queue manager are on the same operating image. CHLAUTH is not relevant to this type of application connection. 2. Client bindings : This is when the application and queue manager use the network to communicate. The application and queue manager may be running on the same machine or they may be on different machines. In MQ a client connection is handled in the form of a server-connection (SVRCONN) channel. Both CONNAUTH and CHLAUTH are applicable, and it is this type of connection which is discussed. The binding steps of a receiving end of a channel When an application connects to a queue manager there is a lot of checking to perform to ensure that both ends of the channel understand what is supported by the other end. The receiving end does some extra checking to ensure that the client is allowed to connect. This checking involves
