MQ-coding allows text messages to be sent and received through application messaging queues. This allows for messages using simple text information and data to be transmitted and utilized with the proper equipment. A WebSphere MQ is a necessary tool in this process.
A queue manager is necessary for this as it guides and affirms that the messages are properly sent and received. There are different kinds of queue managers, such as s dead-letter queue which can store messages that are prevented from being transported from their original location. A transmission queue allows messages to be sent to remote locations or managers but will send them through normal means by default. A proper server is required to supportand maintain the queue in-use.
