- Duration: 3 Days
In this instructor-led course, you learn how to issue calls that use the WebSphere MQ API (MQI). You learn how to code and use calls to complete various functions, such as opening and closing queues and putting messages on or retrieving messages from a queue. You also learn other important topics such as controlling message retrieval, writing programs that change queue attributes, handling MQI security, and managing message channels.
This course includes a brief review of WebSphere MQ and a descriptive introduction to the MQI. It introduces the WebSphere MQ calls that control connections and put messages on a queue. It also describes how to generate correctly formatted request and reply messages. You learn how to place a single message on a queue with an implied open and close for efficiency, use the message ID and correlation ID, browse messages on a queue, and wait for message arrival.
The course also includes a unit on using syncpoint control calls (MQBEGIN, MQCMIT, and MQBACK) that allow WebSphere MQ clients to participate in units of work, MQI security, and asynchronous message consumptions.
The lab environment for this course uses the Linux platform. Programs that are created in the lab exercises are written in C.
This course is designed for experienced business application programmers who must develop applications that use the messaging and queuing techniques that the WebSphere MQ API (MQI) supports.
