This book is the first of its
kind, a book dedicated to tuning the Oracle high availability RAC
architecture. Oracle RAC databases are flexible and robust,
and along with this flexibility comes complexity, making RAC
tuning one of the most challenging areas of Oracle tuning.
Packed with incisive insights and examples from one of
America's leading RAC experts, guru Brian Peasland delivers an
indispensible book for all RAC administrators who need to
guarantee that their RAC systems run at optimal performance.
It's not enough for the DBA to maintain and control RAC
database, the RAC DBA must also have an arsenal of tools and
scripts that will help them ensure that their RAC database run
at optimal levels.
This book will be valuable to all
Oracle professionals who must tune their Oracle RAC systems
for peak performance. Similar to tuning Oracle database
systems in general, Oracle RAC performance tuning covers a
wide variety of focus areas.
Topics will include Oracle
wait events specific to RAC deployments, using Oracle
Enterprise Manager Grid Control and AWR in diagnosing RAC
problems, and RAC utilities such as OS Watcher and ORAchk
(formerly RACcheck). This book will also discuss architecture
issues related RAC performance, delving into the cluster
interconnect, physical disk layout and Oracle 12c new Flex
Clusters.
Oracle RAC also allows the workload the
spread among several low cost servers (scale-out) rather than
a large single server (scale-up), and this book examines these
approaches from a tuning perspective.
Many companies
are working towards private cloud implementations using RAC,
and this book is perfect for the DBA's charged with . Oracle
12c RAC raises the bar with its new multi-tenant database
implementation. Think of multi-tenant as virtualization at the
database level. As more companies start leveraging Oracle 12c
RAC for their enterprise database architecture, it is
important that the system be designed and tuned properly to
ensure the application has a well-performing user experience.
This unique book provides a one-stop location for any RAC
DBA who must become a RAC performance tuning specialist. Most
Oracle RAC books on the market devote only one chapter to
performance tuning.
The information in this book
provides a solid foundation for one’s first RAC deployment,
and provide you with the tools and methods needed to keep your
complex RAC systems running optimally.
While this book is not for beginners, the reader is given
sufficient background throughout the chapters so that most
Oracle DBAs, even those will little Oracle RAC experience,
will be able to understand its contents. Oracle RAC is
inherently complex. This explains the concepts before delving
into highly technical areas. Many in-depth areas of RAC tuning
are explored that help the DBA reveal hidden performance
trends within even the most complex RAC database.
