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.
Note: This recording mode is available only if IBM® WebSphere MQ 7.1 and later is installed and configured in Library Manager.

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

Note: If security is enabled for the queue manager, you must enable certain authorities in the queue manager for the HCL OneTest™ API MQ alias queue recording to access the HCL OneTest™ API alias queue. For information, see Security settings for HCL OneTest™ API MQ alias queue recording.
In Queue Aliasing mode, when recording starts, HCL OneTest™ API creates a topic automatically and reconfigures the queue alias to publish to the topic. HCL OneTest™ API 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, HCL OneTest™ API reconfigures the queues back to the original configuration. If it is not possible (for example, if there is an open connection to the alias), HCL OneTest™ API 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 HCL OneTest™ API 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.
