Hi, We are doing SAP CRM implementation project for one of our US customer. On part of it we are tesing the performance of Oracle database instances, before go-live ( basically load testing for apps & DB ). While testing, we can see ADR block file read / ADR block file write event in AWR. THis is 11g instance on HP-UX IA server. Could you please share your thoughts on this.
