Oracle Enterprise Manager Cloud Control 12c: Managing Data Center Chaos

By: PORUS HOMI HAVEWALA

Overview of this book

Data centers around the world are experiencing an unprecedented era of growth due to expanding data volumes. There is also a corresponding increase in the number of databases and applications. In such rapid-growth centers, it is inevitable that fighting fires daily becomes a common occurrence. There is often no controlled method of performance management, neither is rapidly changing configuration information collected. With the lack of automation and control, Data Centers do not often realize their intended cost-effectiveness and regress into a chaotic and uncontrolled day-to-day type of existence. This was the case until Oracle Enterprise Manager started being used as an Enterprise-wide central management solution, changing the whole game in the process. In this brand new book by Porus Homi Havewala, one of the leading experts in the Oracle space, you will be introduced to the all-encompassing world of Oracle Enterprise Manager Cloud Control 12c, Oracle's premier product for managing and monitoring the Enterprise space. Drawing from the author's many years of experience in the real world, the book brings together the major capabilities of the latest Enterprise Manager software and demonstrates how to ease the growing pains of Data Centers. The book takes you on a descriptive journey of what issues are normally experienced in the Data Center, and how Oracle Enterprise Manager Cloud Control 12c manages to address and resolve many of the issues. The book introduces the reader to the typical chaos in Data Centers and discusses the way these common issues are normally resolved, by manual labor or manual scripting using extensive human resources. Then it will show you how Cloud Control 12c aids in Database Performance Management, Configuration Management, Security Compliance, Automated Provisioning, Automated Patching and Database Change Management. You will learn how Cloud Control 12c allows Exadata Database Machine Monitoring and Management, Test Data Management for data subsetting of large databases, as well as Sensitive Data De-identification using Data Masking. The book includes various real life examples and case studies of actual Oracle customers to show how they have benefited from using Oracle Enterprise Manager. It explores the strong standing of Oracle in the Enterprise Management game, now also strengthened by the new Enterprise Manager Cloud Control 12c.

Testing infrastructure changes


Real Application Testing (RAT) is an Oracle Database Enterprise Edition option that allows you to test out the effects of major or minor infrastructure changes on your database.

This may include any changes at the database layer or below, such as database upgrades from 9.2, 10.1, or 10.2 to 11g, moving from a single-instance database to a RAC database, migrating to a different OS, using a different storage subsystem, moving to Exadata, and so on. It may also include database patches, initialization parameter changes, optimizer setting changes, and so on.

RAT includes Database Replay as well as SQL Performance Analyzer (SPA). Both of these components of RAT can be fully executed via Enterprise Manager Cloud Control 12c.

Database Replay can be accessed by going to Performance | Database Replay on the database menu in Enterprise Manager. The screen appears as follows:
