® MQ Everyplace
® (MQe) is a member of the IBM
MQ family of business messaging products. It exchanges messages with various applications, providing once and once-only assured delivery leveraging the point to point message paradigm.
MQe provides an integrated set of security features enabling the protection of message data both when held locally and when being transferred.
message delivery, the application puts the message to MQe for delivery to the remote queue. MQe simultaneously contacts the target queue and delivers the message. After delivery, MQe returns immediately to the application. If the message cannot be delivered, the sending application receives immediate notification. MQe does not assume responsibility for message delivery in the synchronous case (non-assured message delivery).
message delivery, the application puts the message to MQe for delivery to a remote queue. MQe immediately returns to the application. If the message can be delivered immediately, or moved to a suitable staging post, it is sent. If not, it is stored locally. Asynchronous delivery provides once and once-only assured delivery. After the message is provided to MQe, control is returned to the application. MQe next takes responsibility for assured delivery of the message. Delivery occurs in the background allowing the application to carry on its processing.
MQe also has the ability to exchange messages with WebSphere
MQ host queue managers and brokers. To do this, configure a MQe queue manager with bridge capabilities. Without the bridge, a queue manager can communicate directly only with other MQe queue managers. However, it can communicate indirectly through other queue managers in the network that have bridge capabilities.
As mentioned previously, a point-to-point JMS provider is included with MQe. Initially MQe must be bootstrapped using the supplied connection factory. From then on, standard JMS APIs can be used.

The MQe feature has been deprecated in favor of micro broker.
