TDIPLOCK

If you have a task suspended on resource type TDIPLOCK, with a resource name corresponding to a transient data queue name, the task has issued a request against an intrapartition transient data queue. Another task is already accessing the same queue, and the waiting task cannot resume until that activity is complete.

If tasks frequently get suspended on resource type TDIPLOCK, you need to determine which other transactions use the same intrapartition destination. You might then consider redefining the intrapartition destinations.

You can find further guidance information about the constraints that apply to tasks writing to intrapartition destinations in the CICS Application Programming Guide. For more guidance information about the properties of recoverable transient data queues, see the CICS Resource Definition Guide.
