Message Queuing

MQSeries enables applications to use message queuing to participate in message-driven processing. Applications can communicate across different platforms by using the appropriate message-queuing software products. The applications are shielded from the mechanics of the underlying communications.

MQI ± a Common Application Programming Interface

All MQSeries products implement a common application programming interface (message queue interface or MQI), regardless of the platform on which the applications are run. The calls made by the applications and the messages they exchange are common. This makes it much easier to write and maintain applications than it is when using traditional methods. It also makes it easier to port applications from one platform to another.

The MQI is described in detail in the MQSeries Application Programming Reference book.
