The Application Dependency and Performance (ADP) pages within Enterprise Manager Cloud Control analyze Java EE, SOA, and Portal applications to capture the complex relationships among various application building blocks in its Application Schema model - the core of the Oracle intelligent platform.
Using ADP you can:
Monitor performance of applications deployed in the following type of Servers:
Oracle SOA Suite 11g
Oracle Service Bus
Java EE
Oracle WebLogic Portal
Have visibility into components defined by way of metadata within a framework (for example, components within a composite) with deep dive visibility, where available
View static relationships defined between components and services, such as OSB business and proxy services, and SOA services and references
This chapter includes the following:
Using the insights stored in Application Schema, ADP is able to deliver an Application Service Management (ASM) environment that self-customizes out-of-the-box, evolves with change, minimizes expert involvement, and delivers a holistic, service-oriented view across heterogeneous environments. ADP enables an enterprise to more efficiently manage distributed applications, attain management agility, and lower total cost of ownership.
See the following sections:
Avoiding Involvement from Java EE, SOA, OSB, Portal, and Application Experts
Eliminating Repetitive Do-It-Yourself (DIY) Manual Processes
Today's Java EE, SOA, OSB, and Portal applications enable enterprises to deliver mission-critical business functions to key constituencies - most often their customers, partners, and employees. These composite applications are assembled from many different Java EE components and exposed services distributed across a heterogeneous environment.
To be effective at managing today's complex, distributed Java EE, SOA, OSB, and Portal applications across a heterogeneous environment, enterprises must adopt an intelligent ASM platform with the following characteristics:
Provides holistic, service-oriented views across heterogeneous environments
An intelligent ASM platform must provide high-level service-oriented metrics that map to low-level technology-centric metrics. These measurements must be organized in a service-oriented fashion to deliver a unified, holistic view of the numerous interconnected application components deployed across heterogeneous environments.
Requires minimal Java EE, SOA, OSB, Portal, and application expertise
An intelligent ASM platform must have the ability to capture complex relationships among various interconnected components of today's Java EE, SOA, OSB, and Portal applications. This ability can help minimize reliance on Java EE, SOA, OSB, Portal, and application experts for setting up and maintaining effective APM environments.
Eliminates repetitive DIY manual processes
An intelligent ASM platform must eliminate repetitive DIY manual processes by delivering the ability to self-customize out-of-the-box and evolve with change. Elimination of these repetitive DIY manual processes is the only way to deal with rising complexity and rapid rate of change with ease.
Today's mission-critical business functions are powered by Java EE, SOA, OSB, and Portal applications that comprise numerous interconnected components deployed across highly distributed environments. To manage these applications effectively, enterprises must first gain an understanding of the complex relationships among the business functions, associated interconnected components, and the underlying runtime environments. To enable clear and accurate understanding, IT organizations need holistic, service-oriented views that span across heterogeneous environments.
Furthermore, appropriate rendering of these views enables users at different levels of the organization to collaborate with each other and do their respective jobs more efficiently.

Application Schema Navigation provides efficient ways for you to access relevant information using techniques like hierarchical traversal, architecture model navigation, string queries, drill down, drill out and more.
To manage Java EE, SOA, OSB, and Portal performance effectively, IT organizations must adopt an intelligent platform like ADP that requires minimal expertise to set up and maintain. Unlike conventional APM toolkits, ADP does not rely on human expertise to set up and maintain customized APM environments. Instead, ADP uses a unique model-driven approach that leverages the information stored in its Application Schema model to keep the involvement of experts to the minimum. ADP's unique ability to self-customize out-of-the-box and evolve with change makes it the perfect solution for managing not only custom enterprise applications, but also applications developed by external parties.
Based on a unique model-driven approach, ADP eliminates repetitive DIY manual processes. To achieve this level of self-customization and continuous change adoption, ADP uses its AppsSchema modeling technology to perform the critical task of analyzing application structure and infrastructure configuration. After capturing these insights in the Application Schema model, ADP leverages this information to establish a fully customized ASM environment. To keep this environment up-to-date, ADP continuously updates the Application Schema model as new applications are deployed and changes are applied. ADP's unique ability to self-customize out-of-the-box and evolve with change enables fast time-to-value, low total-cost-of-ownership (TCO), and maximal return-on-investment (ROI).
Oracle provides the industry's first intelligent ASM platform for Java EE, SOA, OSB, and Portal. Unlike conventional APM toolkits, ADP analyzes these applications and captures complex relationships among various application building blocks in its Application Schema model - the brain of this intelligent ASM platform.
Using the insights stored in the Application Schema model, ADP is able to deliver an ASM solution that self-customizes out-of-the-box, evolves with change, minimizes expert involvement, and delivers a holistic, service-oriented view across heterogeneous environments. Adopting an intelligent platform such as Oracle will enable the enterprise to more efficiently manage distributed applications, attain management agility, and lower total cost of ownership.
ADP employs a multi-tier, fully distributed, configurable architecture to provide the scalability and flexibility to meet the changing needs of enterprise deployments.
ADP operates as a service on the machine and automatically begins running when the machine first boots, and remains on perpetually. ADP is typically installed on its own machine and dedicated to monitor a group of managed application servers.
The following core components are deployed to form the ADP ASM system.
ADP Java Agents are the data collectors of the ADP ASM system. ADP Java Agents are deployed to all managed application servers to perform a series of tasks including collecting performance managements, tracking contextual relationships, and summarizing data in real-time while introducing as little overhead as possible. At the expiration of the predefined aggregation interval, these agents forward the summarized data to ADP for additional analysis. For various Java EE platforms such as Oracle SOA Suite and Oracle WebLogic, ADP leverages their deployment infrastructures to quickly deploy the ADP Java Agents to all application servers.
ADP Manager is the core analytical engine of the ADP ASM system. In real-time, ADP Manager performs complex mathematical modeling and statistical calculations with summarized data from all ADP Java Agents. ADP Manager can be configured with a backup to provide higher level of availability.
Although the ADP Manager does not have high availability (HA) built into it, administrators can have a backup ADP Manager installed on a separate machine; this backup ADP Manager points to the same database but is disabled. If the production ADP Manager fails, the backup ADP Manager can then be enabled against the same database. The backup ADP Manager then rediscovers the application after the agent is redeployed from the backup ADP Manager, to the managed resources in order to synchronize them. All metrics are preserved, assuming the model does not change in the short time frame it takes to bring the backup ADP Manager online.
The key with this backup procedure is to backup the database that ADP uses as its repository in order to preserve the historical data. On the modeling side, the backup ADP Manager has to rediscover the application which should happen automatically, as long as the resources are configured and the new agent has been deployed.
If historical data preservation is not a necessity, users can simply have another ADP Manager and database and swap agents reducing the backup effort considerably.
The ADP User Interface (ADP UI) is the primary user interface for ADP users. Users can use ADP UI to set Service Level Objectives (SLOs), analyze monitoring data, and more. The ADP UI is fully configurable. To access ADP:
