The Interface Data Link Control (DLC) Write Queue Statistics Workspace analyzes output at the Data Link Control (DLC) layer level, providing information related to the datapath device number associated with the selected interface. Data is returned for each active OSA-Express queued direct I/O (QDIO) or HiperSocket datapath device number (data subchannel address). When interfaces share a datapath device number (data subchannel address), the statistics for each interface sharing the datapath device will be identical. There is one row of data returned for each of the one to four possible write priority queues that are supported for the datapath device number (data subchannel address) for each interface.
Note: This workspace returns data only on systems running on z/OS v1.12 or later
