WebSphereMQ Advanced Programming

Audience

This class is for MQ Programmers who wish to write complex messaging Applications or use any of WebSphere's more advanced programming features such as channel exits. This class is also necessary for those who will act as in-house consultants to junior staff.

Prerequisites

The participant should have a sound working knowledge of WebSphere MQ design and the WebSphere MQ program calls, such as might be gained from the WebSphere MQ Application Programming class, plus ideally six months' practical experience.

Duration

3 days. Hands on.

Course Objectives

Upon completion of this course students should be able to:

• Design and code complex transactions using any of the three kinds of WebSphereMQ triggers, specifically the queue depth type of trigger in conjunction with MQSET.
• Write and implement a trigger monitor program.
• Code WebSphereMQ exits, particularly the channel message and data conversion exits.
• Write and implement handlers for dead-letter queues and performance events.
• Use WebSphereMQ distribution lists for: fuzzy broadcast queries; precisely-controlled multi-destination transactions.
• Implement Web access to servers using alternate userid's.
• Implement multiple instances of server applications in a cluster of WebSphereMQ queue managers Participants demonstrate achievement of these goals by solving several programming labs, work that is designed to stretch them.
• Message Properties.
