Client channel definition tables, or CCDTs for short, are convenient ways for the client to read channel definitions. A CCDT file contains all CLNTCONN channel definitions of a particular queue manager. So, how does a client using a CCDT know which channel to use ? The answer lies in the way the CCDT itself is written by the queue manager. The queue manager writes channel definitions on to the CCDT file in alphabetical order. So, the client picks up the first channel whose QMNAME parameter matches with the queue manager name parameter of the... [More]

If you want to quickly get started with writing a micro broker JMS client and connecting to a micro broker, here's how you do it.
