TDP1251 WAITS FOR ADDITIONAL XMS CELLS: count
This display indicates the number of times that no cell was available to process a request that required more than one cell from the largest cross-memory cell pool.
If a request requires more than one cell from the largest size of the three cross-memory cell sizes, the request must wait. The number of cells for the largest cross-memory cell size should be no smaller than the number for the two smaller cross-memory cell sizes.
Use of the 'ADD XMSCELLS' command to add cells to the largest cross-memory cell pool.
