Hello,

Since we have migrated to z/OS V1.9 from V1.7 (Including, of course, the new 
Storage Management algorithms), the counts for Blocked Paging in both the 
SMF Type 30 and RMF Type 71 records have been virtually reduced to zero 
while the Demand Paging Rate has remained similar to what is was in V1.7.

Two questions, please:
1)  Is block paging still the concept of gathering multiple pages in Central 
Storage and writing them out to Auxiliary Storage with one I/O?  It was 
mentioned to me that this concept is obsolete.

2)  Has anyone else seen these counts go to zero?  If so, do you know why 
and/or how to get Blocked Paging turned back on?

Thanks for your time,
Wayne Bell
