Issue/Introduction

What are the possible downsides of these two settings ZIIP-USE=SRB or ZIIP-USE=NO?

 

Environment

Release : 20.0

Component : CA Insight Database Performance Monitor for DB for z/OS

Resolution

ZIIP-USE=SRB: uses SRB mode but doesn't use zIIP. Use the SRB setting to determine how much CPU consumed by the datacollector can be offloaded to zIIP processors. zIIP processors are not utilized with this setting.

ZIIP-USE=NO Does not use zIIP or SRB.
