Abstract

HASM-UNPRED ENHANCEMENT TO ASYNCHRONOUS DELIVERY MODE IN LOW
SYNC PRIORITY DESIGN.

Error Description

An enhancement to the current Asynchronous delivery mode design
is being implemented to benefit nodes with bigger workloads    
while network traffic is also high. The design change will      
allow the local work to continue without sending Geographic    
Mirroring into suspends as frequently.                          
                                                               
*NOTE - This PTF is intended for networks with low bandwidth    
where synchronization is a much lower priority in relation to  
run-time.                                                      
This design is for cases where run-time is the most important  
thing, and getting synchronization complete is secondary. So    
the synchronization can run at a low priority, along with the  
fact that bandwidth is low while keeping in mind that the      
synchronization should not be consuming the bandwidth          

Problem Summary

Please see the ERROR DESCRIPTION section.                      

Problem Conclusion

Changes will be made to the synchronization tasks such that    
synchronization processing while in a low synchronization      
priority and in asynchronous delivery mode does not consume as  
much network bandwidth.
