Session title: zIIP Experiences: Exploitation Not Abuse
Session abstract: With the constant focus on controlling MIPs consumption on today’s mainframe, IT staffs are being pressed to get every cycle possible out of their System z Integrated Information Processor (zIIP) specialty engines and the now defunct System z Application Assist Processors (zAAP). DB2 for z/OS and related processes that run on System z can take advantage of these processors, and will be covered in depth during the presentation. There are two methodologies involved in maximizing off-load potential: 1) ensure everything that is currently eligible is getting access to zIIP cycles and tune appropriately 2) then look at other avenues to increase potential off-load. We will delve into both of these to investigate maximum zIIP exploitation and discuss the reality of current customer environments. We also need to understand what new functions are being offloaded in each release (up through V12) and what the demise of the zAAP means for us.
