Abstract

OSP New fields for Active Memory Deduplication in QAPMSHRMP

Error Description

This change provides support for Active Memory Deduplication    
within Collection Services data. New metrics are supported in  
the QAPMSHRMP file.                                            

Problem Summary

                                                               
This change provides support for Active Memory Deduplication    
within Collection Services data. New metrics are supported in  
the QAPMSHRMP file.                                            

Problem Conclusion

Additional metrics are provided for fields that were previously
reserved in file QAPMSHRMP:                                    
                                                               
SMFIELD1 - Partition logical memory deduplicated. The amount of
the partition's logical memory (in bytes) mapped to a smaller  
set of physical pages in the shared memory pool because it was  
identical to other pages in the shared memory pool.            
                                                               
SMFIELD4 - Pool physical memory deduplicated. The amount of    
physical memory (in bytes) within the shared memory pool that  
logical pages of memory from the partitions sharing the pool    
have been mapped to because of deduplication.                  
                                                               
MPFIELD1 - Unscaled deduplication time. The amount of processing
time, in microseconds, spent deduplicating logical partition    
memory within the shared memory pool.                          
                                                               
MPFIELD2 - Scaled deduplication time. The amount of scaled      
processing time, in microseconds, spent deduplicating logical  
partition memory within the shared memory pool.                
                                                               
An updated template file for the QAPMSHRMP file exists in QSYS.
It has updated column headings for the modified fields. This    
template will be used to create QAPMSHRMP in libraries where it
doesn't already exist. Existing collection libraries (for      
example, QPFRDATA) that contain a prior version of QAPMSHRMP are
not affected by this PTF.
