Abstract

LIC BASE FUNCTION TO ENABLE TECHNOLOGY REFRESH

Error Description

Technology Refresh                                              

Problem Summary

This change provides base function to enable extensions for a  
Technology Refresh.                                            

Problem Conclusion

Additional base function is provided in this PTF.              
                                                               
This Technology Refresh PTF also provides a potential          
performance improvement.  The IBM i IPL path code has been      
adjusted to perform some coherence checks related to mainstore  
only during the initial IPL of a release on a Power system that
contains this PTF.  All later Technology Refreshes and newer    
releases will contain this code.  The first IPL after applying  
this PTF will take the usual amount of time.  Subsequent IPLs  
may no longer need to perform these same coherence checks, and  
may therefore be faster.  The larger the amount of mainstore,  
the greater the potential for noticeable improvement in IPL    
time.
