Recording by using Queue aliasing mode

An alias queue is an WebSphere® MQ object that refers to another queue. The object to which the alias is pointing can be changed without affecting the client application, which continues to reference the alias.

This recording approach can be used where the publishing application uses a queue alias name rather than an actual queue name.

In Queue Aliasing mode, when recording starts, Test Integrations and APIs creates a topic automatically and reconfigures the queue alias to publish to the topic. Test Integrations and APIs then sets up two subscribers to the topic:

• One subscriber is the original queue (so that the subscriber still receives the message).
• The other subscriber is a queue that is used for Recording Studio.

Note: Recording Studio warns you if it is unable to perform the required reconfiguration.

When recording is stopped, Test Integrations and APIs reconfigures the queues back to the original configuration. If it is not possible (for example, if there is an open connection to the alias), Test Integrations and APIs displays a warning message that it could not reconfigure. In such cases, manual reconfiguration by using the queue manager is required. Alternatively, starting and stopping the recording again will force Test Integrations and APIs to reattempt the reconfiguration. However, it can be attempted only after you disconnect the applications that are holding open any connections to the queue alias.
