Hi z/OS folk
Is anyone using the SYSBPM Method=N (rather than default method S)?
Did you see CPU benefits by making the change?
What size buffer pool do you run with method N?
What size buffer pool cache?
The manual does say “A disadvantage of METHOD=S can be the high CPU time that is consumed by the selection process when browsing the buffer pool from top to bottom”.
I using Nat414 under NIM and batch on z/OS.
