Abstract

LIC-OTHER-PERFM REDUCE MACHINE GATING AND SEIZE CONTENTION IN
MATPTR AND MATSOBJ

Error Description

Machine gating and seize contention on libraries in Materialize
Pointer (MATPTR) and Materialize System Object (MATSOBJ) MI    
instructions may impact partition performance.                  

Problem Summary

Please see the ERROR DESCRIPTION section.                      

Problem Conclusion

Licensed Internal Code has been changed to provide support for  
reducing machine gating and seize contention on libraries in    
Materialize Pointer (MATPTR) and Materialize System Object      
(MATSOBJ) MI instructions. This fix does not reduce the        
contention, it adds framework for use by future fixes to reduce
the contention.
