SLOT nn BELOW THE LINE OVERFLOW
Reviewed TPXOPER display command D STOR.
Shows 0% Current Use and 0% Max Use with 3 Failed. How is that possible?
From TPXOPER D STOR:

Release: 5.4
Component: TPX for Z/Os
TPX started task is using REGION=5000K.
Change REGION=5000K to REGION=0M in TPX Proc. Rcycle TPX.
With REGION 5000K not enough storage available to assign to slot 12 once TPX modules and SMRT, PROFILEs, etc., were loaded.
This is evident in the TPXOPER display above, with the zero value for slot 12 Count and Bytes.
In this situation, TPX continued by using Dynamic Storage Area (DSA) when otherwise slot 12 below the line would have been used.
TPX 5.4 - Adjust Storage Parameter ...this explains how TPX manages storage
Why does CA recommend the region size for the TPX proc be set to 0M?
