This chapter provides an overview of Enterprise Manager Cloud Control 12c and helps you understand its architecture and the various core components that are integrated within the product.
Oracle Enterprise Manager is Oracle's integrated enterprise information technology (IT) management product line, which provides the industry's only complete, integrated, and business-driven enterprise cloud management solution.
Figure 1-1 illustrates how Enterprise Manager Cloud Control offers a solution that enables you to monitor and manage the complete Oracle IT infrastructure from a single console.
Figure 1-2 shows a sample Enterprise Manager Cloud Control architecture and illustrates how these core components fit into the architecture. In Figure 1-2, the load balancer and the multiple Oracle Management Services are depicted only to indicate how a sample Enterprise Manager Cloud Control architecture would look in a large organization.
Oracle Management Agent (Management Agent) is an integral software component that is deployed on each monitored host. Oracle Management Service is a Web-based application that orchestrates with the Management Agents and the Management Plug-ins to discover targets, monitor and manage those targets, and store the collected information in a repository for future reference and analysis.
The Oracle Management Repository (Management Repository) is a storage location where all of the information collected by the Management Agent is stored.
Technically, the Oracle Management Service uploads the monitoring data it receives from the Management Agents to the Management Repository. At the time of installation, the Enterprise Manager Cloud Control Installation Wizard configures the Management Repository in your existing, certified database. The core Enterprise Manager Cloud Control features for managing and monitoring Oracle technologies, such as Oracle Database, Oracle Fusion Middleware, and Oracle Fusion Applications, are now provided through components known as plug-ins that can be downloaded and deployed using the new Self Update feature. Table 1-1 lists the default plug-ins that are installed on Oracle Management Service and the Management Agent by default with a new Enterprise Manager system. Enables you to monitor and manage Oracle Database and related targets such as Oracle Real Application Clusters (Oracle RAC), Oracle Automatic Storage Management (Oracle ASM), and so on. Enables you to log in to My Oracle Support from within the Enterprise Manager Cloud Control console, search the knowledge library for notes and documents, raise service requests, and create patch plans and templates for patching monitored targets. The Enterprise Manager Cloud Control console is the web-based user interface for Enterprise Manager Cloud Control. EMCTL is a command-line tool used to execute certain tasks on Oracle Management Service (OMS) and Management Agents. The Enterprise Manager Command Line Interface (EM CLI) tool enables you to access Enterprise Manager functionality through a command-line interface. Oracle Enterprise Manager framework is enterprise-ready and is designed to manage and monitor critical business operations to ensure smooth running of enterprise data centers. World class enterprise monitoring is about monitoring the status of your infrastructure and applications, notifying the appropriate IT staff when incidents occur, and reporting on status, history, and trends to interested parties throughout IT and the business. Oracle provides advanced, out-of-the-box application management solutions for Oracle E-Business Suite, Siebel, Peoplesoft, JD Edwards, and Fusion Applications.
Enterprise Manager also offers advanced management capabilities for managing custom applications, integrations, and extensions.
Oracle revolutionized the field of enterprise database management systems with the release of Oracle Database 10g by introducing the industry's first self-management capabilities built right into the database kernel.

For more information about automatic tuning, see Automatic SQL Tuning Advisor and Managing Diagnostic Data. Oracle Enterprise Manager Cloud Control 12c provides a comprehensive management solution for Oracle WebLogic Server, Oracle Fusion Middleware, and non-Oracle middleware technologies.
Oracle Enterprise Manager provides an integrated and cost-effective solution for complete physical and virtual server lifecycle management.
Oracle Enterprise Manager, besides being the best suite of management products for Oracle technologies, also provides a comprehensive solution for the management of heterogeneous data centers (including Microsoft SQL Server and JBoss Application Server) through its rich collection of extensions known as plug-ins and connectors. Oracle Enterprise Manager Cloud Control is Oracle's complete cloud lifecycle management solution.
Lifecycle Management is a comprehensive solution that helps database, system, and application administrators automate the processes required to manage the lifecycle of Oracle technology. Enterprise Manager 12c provides a complete Application Performance Management (APM) solution for custom applications and Oracle applications (including E-Business Suite, Siebel, PeopleSoft, JD Edwards, and Fusion Applications).
User Experience Management: Real user monitoring and synthetic transaction monitoring with Real User Experience Insight (RUEI) and Service Level Management (SLM) beacons, respectively. There are two ways to monitor Web site user experience: using real traffic from real customers or using synthetic traffic (traffic artificially created by software to mimic the load that the Web site would be expected to receive).

Java monitoring and diagnostics: Zero-overhead, production Java diagnostics for Oracle and non-Oracle platforms.
Application Performance Analytics: Rich reporting and analytic capabilities on real user activities and transaction monitoring data. Oracle's Application Quality Management products provide a complete testing solution for Oracle Database, Oracle Packaged Applications, and custom Web applications. Infrastructure Testing: Application Replay and Real Application Testing enable realistic, production-scale testing of the application and database infrastructure.
Test Data Management: Oracle Test Data Management and Data Masking provide efficient, automated, and secure test system creation capabilities for Oracle and non-Oracle databases, with out-of-the-box templates for Oracle packaged applications.
Scripting on this page enhances content navigation, but does not change the content in any way. Oracle Enterprise Manager aims to help IT organizations to manage entire Oracle-based cloud stack from application to disk. I tried to demonstrate how to install Oracle Enterprise Manager Grid Control 11g and Ops Center 11g in my previous blogs (Ops Center, Grid Contol). Before we begin to set up the integration, let’s examine the following diagrams to see how the integration will work. This is a simple diagram showing communication between a target server and OEM Grid Control. The patchset contains 7 zip files but we need only the first 3 zip files to upgrade our grid and database. Oracle Enterprise Manager Ops Center is the hardware management solution for Oracle’s Sun environments. Enterprise Manager Ops Center has a text based installer but I should say that it works really well.
I was searching NoSQL databases and see that Oracle provides a NoSQL database called Berkeley DB. Berkeley DB is a high-performance embedded database originated at the University of California, Berkeley. It supports multiple databases: You can use SQL Developer for Microsoft Access, Microsoft SQL Server, MySQL, TimesTen, DB2 and (of course) Oracle. TOAD has a better interface because of using native Windows components but you can get used to SQL Developer if you spend time on it.
Oracle Enterprise Manager creates business value for IT by leveraging the built-in management capabilities of the Oracle stack for traditional and cloud environments, enabling customers to achieve unprecedented efficiency gains while dramatically increasing service levels. They are not a prerequisite or a requirement for an Enterprise Manager system installation. It is responsible for monitoring all of the targets running on those hosts, communicating that information to the middle-tier Oracle Management Service, and managing and maintaining the hosts and its targets.
Oracle Management Service also renders the user interface for Enterprise Manager Cloud Control.
It consists of objects such as database jobs, packages, procedures, views, and tablespaces. The Management Repository then organizes the data so that it can be retrieved by the Oracle Management Service and displayed in the Enterprise Manager Cloud Control console. In addition to these default plug-ins, you can optionally install other plug-ins available in the software kit (DVD, downloaded software bundle, and so on). With the help of the console, you can monitor and administer your entire computing environment from one location on the network. You can use it for tasks such as starting or stopping OMS instances, setting properties on OMS instances, or getting a list of targets being monitored by a specific Management Agent. It is accessible through classic programming language constructs, enabling tasks to be created and run either from the command-line or programatically. Oracle Enterprise Manager provides rich monitoring features as a foundation for monitoring all components of your IT infrastructure (Oracle and non-Oracle) as well as the applications and services that are running on them. They provide end-to-end, integrated application monitoring and management capabilities, resulting in improved availability, predictability, and reliability. Today, after several releases and continuous improvement of this intelligent management infrastructure, Oracle Database provides the most extensive self-management capabilities in the industry, ranging from zero-overhead instrumentation to integrated self-healing and business-driven management.
By delivering comprehensive provisioning, patching, monitoring, administration, and configuration management capabilities through a web-based user interface, Enterprise Manager significantly reduces the complexity and cost associated with managing Oracle VM, Linux, UNIX, and Windows operating system environments.
With a move to virtualization, a top benefit expected from private cloud adoption is cost savings through standardization for operational efficiency.
It is the industry's first complete solution including self-service provisioning balanced against centralized, policy-based resource management, integrated chargeback, and capacity planning, and complete visibility of the physical and virtual environment from applications to disk. It eliminates manual and time-consuming tasks related to discovery, initial provisioning, patching, configuration management, and ongoing change management. The APM solution is designed for both cloud and enterprise data center deployments and is supported on Oracle and non-Oracle platforms.

They use real, production workloads to generate load against applications or databases under test and do not require any script development or maintenance.
While Grid Control manages Applications, Middleware and Database layers, Ops Center manages hardware, storage, network, virtualization, and operating system layers. Now I’ll try to show how to integrate Grid Control with Ops Center to manage both software and hardware infrastructure. Ops Center simplifies resource discovery and monitoring, provides OS and firmware provisioning, performs update and patch management and supports hardware management from power up to production. It’s fast, reliable and used in several applications such as Evolution (email client), OpenLDAP, RPM (The RPM Package Manager) and Postfix (MTA). Berkeley DB JE supports almost all features of traditional Berkeley DB such as replication, hot-backups, ACID and transactions. If you do not have a load balancer, then the Management Agents communicate directly with the Oracle Management Services.
Oracle Management Services is deployed to the Oracle middleware home (middleware home), which is the parent directory that contains the Oracle WebLogic Server home, the Oracle Management Service home, the Management Agent home, the plug-in home, the Java Development Kit (JDK), the Oracle Management Service instance base directory, the Oracle Web tier directory, the Oracle common directory, and other relevant configuration files and directories. Because data is stored in the Management Repository, it can be shared between any number of administrators accessing the Enterprise Manager Cloud Control. For example, when a new version of Oracle Database is released, you can simply download and deploy the latest Oracle Database plug-in, which will include management support for the latest release. All the systems and services including enterprise application systems, databases, hosts, middleware application servers, listeners, and so on, are easily managed from one central location. EM CLI enables you to access Enterprise Manager Cloud Control functionality from text-based consoles (shells and command-line windows) for a variety of operating systems.
With a next-generation user interface, it provides a rich, intuitive console that can be customized to suit different roles. These features enable IT to proactively monitor and resolve issues by business priority, implement operational best practices for monitoring, and provide consistent, high quality service in support of business goals.
Oracle Enterprise Manager's management capabilities include user experience management, performance management, change and configuration management, patching, provisioning, testing, integrated diagnostics, and automatic tuning.
In addition, enterprises using Oracle Sun hardware can obtain deep insight into their server, storage, and network infrastructure layers and manage thousands of systems in a scalable manner.
These extensions are built upon the same management framework that is used for Oracle products, and therefore provides the same level of stability and richness as the Oracle products. However, without proper management capabilities, expected economic benefits of cloud computing will not be realized. In addition, the solution provides compliance frameworks for reporting and managing industry and regulatory compliance standards. SLM beacons are components within the monitored environment that send out synthetic traffic. With Application Replay or Real Application Testing you can reduce your testing time by more than 80%.
In contrast to most other database systems, Berkeley DB provides relatively simple data access services.
I’ll just show how to configure SQL Developer to connect Microsoft SQL Server and MySQL. While deploying the Oracle Management Service, the Enterprise Manager Cloud Control Installation Wizard installs Oracle WebLogic Server if it does not already exist in your environment.
You can also perform tasks in bulk mode by creating Jython scripts that are passed in using the tool. Oracle Enterprise Manager framework also has advanced capabilities such as self-update where key components such as target plug-ins, compliance policies, and deployment procedures can be updated automatically as newer versions become available. Oracle Enterprise Manager helps customers to accelerate the adoption of virtualization and cloud computing to optimize IT resources, improve hardware utilization, streamline IT processes, and reduce costs. Finally, all of the on-premise instrumentation can be connected in real-time to My Oracle Support for complete communication between Oracle and customers.
Typically, they test the performance and availability of business-critical services in the infrastructure as part of SLM.
They provide the most efficient, optimized and highest quality testing for validating application and database infrastructure changes. I’ve decided to translate (in fact, re-write) and publish it in English, and this is what you are reading now. Oracle Enterprise Manager is integrated with OVM 3.0 and higher and Oracle Virtual Assembly Builder.
