Presentation Title
Session #1: RAC Performance Taxes
Session #2: So as I Was Saying about RAC & MTU
Abstract
#1: RAC Performance Taxes – In this presentation, we will outline the major RAC performance impact taxes around SQL Parallization, ASM, what we can do to avoid them via RAC Tax Loopholes and try to answer the question "Are RAC & Performance mutually exclusive?"
#2: So as I was Saying about RAC & MTU – This presentation will focus on the details of optimizing the RAC interconnect and MTU. We will cover Network Latency, Protocols, and CPU impact. Attendees will gain the understanding of the impact the interconnect can have on not so obvious performance issues, specifically the dreaded "unaccounted-for between dbcalls". We will be using an updated simple XLS tool first introduced last year during the training day.
