MQSeries Programming Patterns

3.4. Architectural model

MQI architecture is a simple, straightforward implementation of the different features available in MQSeries.

The different calls directly refer to a basic MQSeries operation such as getting messages from a queue or putting messages to a queue. These calls can be grouped based on their functionality as follows:

• Connecting to and disconnecting from a queue manager:

  MQCONN, MQCONNX, and MQDISC

• Open and close an MQSeries object, such as a queue:

  MQOPEN and MQCLOSE

• Put one or multiple messages on a queue:

  MQPUT and MQPUT1

• Browse or remove messages from a queue:

  MQGET

• Inquire about the attributes of an object:

  MQINQ

• Set some of the queue attributes at runtime:

  MQSET

• Manage local or distributed transactions:

  MQBEGIN, MQCMIT, and MQBACK ...
