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

Chapter 2. Enter Oracle Cloud Control

What if we told you that there is an enterprise-class management product from Oracle, which, if used appropriately, would help in resolving the chaos of the data centers?

Yes, there indeed is such a product. Enter Oracle Enterprise Manager Cloud Control 12c, which is the latest version of Oracle's Enterprise Manager. This is installed centrally on a dedicated server and used for managing and monitoring the entire Oracle Technology Stack, with an Agent placed on each Target that Enterprise Manager is to manage or monitor.

In the previous versions of Enterprise Manager, 11g and 10g, the product could optionally be installed locally when the database software or application server software was installed on a server. In this cut-down form, it was known as Oracle Database Control or Oracle Application Server Control, respectively. This type of single Target Enterprise Manager is no longer available in the 12c version at the time of writing this book.

What we...

The Grid – where the cloud came from


In 2003, Oracle Database 10g was released—where the "g" stood for Grid.

Oracle had previously released Real Application Clusters (RAC) in Oracle 9i, which was the first active/active database system (multiple nodes and instances accessing the same database).

This technology made it possible to cluster large numbers of smaller servers and place the application's database on the cluster as a whole. So, instead of placing the database on a larger and dedicated expensive server that had been sized suitably to accommodate the changes for the next two years of application life, it could be placed on a cluster of smaller servers, sized appropriately.

As the application's demand increased, it would be easy to just add an extra node to the database cluster and expand horizontally instead of vertically. The database services (applications) could also share any of the nodes in the cluster instead of having a dedicated server installed for each application. This intention...

Overview of version 12c


We can now have a quick introductory look at the latest version of Enterprise Manager, which is Cloud Control 12c. The console login appears as follows:

We can guess from this first splash screen that Cloud Control 12c has strong Oracle Application Developer Framework (ADF) looks and features, and we won't be far wrong. The new user interface in Enterprise Manager Cloud Control 12c was indeed developed using the ADF.

To make things interesting right at the outset, the splash screen of the console login also highlights some of the key features of Enterprise Manager – a section titled New in this Release and a Did you know... section. Every time you go to this console login, some new information is displayed. You can also expand any of the points to show more information.

In this new version, you can select your own home page—the page you see when you log in to Cloud Control. Suppose you have just installed Cloud Control and are logging in for the very first time, you...

Striking new features in 12c


Enterprise Manager Cloud Control 12c is a huge release with a plethora of new features. A few of the outstanding features are described shortly. If some of the terminology is new at this stage, no need to worry; we will go to the appropriate detail later on in most cases.

The infrastructure of Enterprise Manager Cloud Control 12c is now more scalable, performant, and reliable, to enable it to support millions of different Targets—much more than the tens of thousands of Targets you could scale up to in previous versions. The Enterprise Manager Framework has been enhanced to a pluggable framework that allows you to download and deploy any plugin via the new self-update feature. The plugins, which were primarily meant for non-Oracle databases, hardware, and software in the past, are now redefined so that even the Oracle Database or Middleware is managed via a plugin. This is quite a change to the basic architecture of Enterprise Manager, which is now more modular...

Bonus sections


The rest of the sections in this chapter deal with the steps of repository installation, OMS installation, Agent installation, post-installation steps, upgrade of existing Enterprise Manager installations, and also the recommended architecture for very large sites, along with disaster recovery tactics.

These sections can be downloaded from the Packt website from the location:

Description

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.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub.

When we publish the book, the code files will also be available to download from the Packt website.
