Titlebook: Expert Oracle RAC Performance Diagnostics and Tuning; Murali Vallath Book 2014 Murali Vallath 2014

AFFIX

Testing for Scalability,RAC is a clustered database solution that provides two major functions, namely, scalability and availability for business continuity. We discussed testing the hardware and application for availability in Chapter 3. In this chapter,we focus on testing for scalability.

Tuning the Cluster Interconnect,In the previous chapter, we discussed that RAC was a configuration of multiple instances clustered together to provide a scalable, high availability environment for information exchange. These servers communicate with each other using a private network called the cluster interconnect.

The book takes a deep look at optimizing RAC databases by following a methodical approach based on scientific analysis rather than using a speculative approach, twisting and turning knobs and gambling on the system..The book starts with the basic concepts of tuning methodology, cap

Tools and Utilities,le ideally a more scientific approach to performance optimization is preferred, performance engineers start out with intuition before using scientific data. The performance engineer or DBA collects data or statistics from the following places:

Seldom do they realize that this could lead to potentially rewriting certain areas of the code that are poorly designed and lead to poor performance.
