What to do if messages are building up on your SYSTEM.MANAGED.DURABLE queues or filling your file system

If your WebSphere® MQ Explorer plug-in uses a durable subscription on the coordination queue manager, messages can build up on the SYSTEM.MANAGED.DURABLE queues. If you have a high-volume WebSphere MQ File Transfer Edition network, use the WebSphere MQ Explorer plug-in infrequently, or both, this message data can fill the local file system.

To remove the buildup of messages on the SYSTEM.MANAGED.DURABLE queues, you can perform one of the following actions:
  • Start the WebSphere MQ Explorer that uses the durable subscription. The WebSphere MQ File Transfer Edition plug-in for WebSphere MQ Explorer consumes the messages from the queue.
  • Delete the messages from the queues manually.
To avoid this happening, you can specify that the WebSphere MQ Explorer plug-in use a non-durable subscription to the coordination queue manager. Perform the following steps in your WebSphere MQ Explorer:
  1. Select Window > Preferences > WebSphere MQ File Transfer Edition
  2. From the Transfer Log subscriber type list, choose NON_DURABLE.
