Using the adapter

The application programs and the IMS adapter run in the same address space. The queue manager is separate, in its own address space.

You must link-edit each program that issues one or more MQI calls to a suitable IMS language interface module, and, unless it uses dynamic MQI calls, the WebSphere MQ-supplied API stub program, CSQQSTUB. When the application issues an MQI call, the stub transfers control to the adapter through the IMS external subsystem interface, which manages the processing of the request by the message queue manager.
