DQM implementation

 

This chapter describes the implementation of the concepts introduced in Making your applications communicate.

Distributed queue management (DQM):

• Enables you to define and control communication channels between queue managers

• Provides you with a message channel service to move messages from a type of local queue, known as a transmission queue, to communication links on a local system, and from communication links to local queues at a destination queue manager

• Provides you with facilities for monitoring the operation of channels and diagnosing problems, using panels, commands, and programs

This chapter discusses:

• Functions of DQM

• Message sending and receiving

• Channel control function

• What happens when a message cannot be delivered?

• Initialization and configuration files

• Data conversion

• Writing your own message channel agents
