Fusion Apps - Architecture for Beginners

I was trying to build resource base with Fusion Apps knowledge. It's a huge subject. So I was wondering how to jump start with some basic ideas. Thought of putting things together from different places. Hope this will help some of you who are still struggling to find out where to start from. Here we go with the building blocks

An installation of Oracle Fusion Applications is logically broken up into groups of features. Each set of features is known as product offerings, which represent the highest-level collection of functionality that you can license and implement. A provisioning configuration is a collection of one or more product offerings. During installation, you select a product offering or a combination of offerings as a way to install the product families. Product families are comprised of one or more Java EE applications specific to Oracle Fusion Applications. An application can contain multiple products, and a product can also span multiple applications. A product typically has a one-to-one correspondence with an EAR file. Figure 1–2 shows two applications, PayablesApp and ReceivablesApp, each of which is mapped to the same product, Payments.

 Oracle Enterprise Manager Fusion Applications Control

Oracle Enterprise Manager Fusion Applications Control (Fusion Applications Control) enables you to manage a single product family in an Oracle WebLogic Server domain for the Oracle Fusion Applications environment, including the products, applications, and Oracle Fusion Middleware components. As a part of management, you can monitor the runtime performance metrics for the various Oracle Fusion Applications

and Oracle Fusion Middleware components.

Oracle Enterprise Manager Cloud Control

Oracle Enterprise Manager Cloud Control (Cloud Control) enables you to monitor and manage the complete IT infrastructure for Oracle Fusion Applications from a single console. You can monitor all the product families, Oracle Fusion Middleware components, and the Oracle Database. For example, you can monitor all the Oracle WebLogic Server domains for all the product families from one console.

Oracle Enterprise Manager Database Control

Oracle Enterprise Manager Database Control (Database Control) enables you to manage the Oracle Database.

Weblogic Server Domains

 See "What Is an Oracle WebLogic Server Domain?" in the Oracle Fusion Middleware Administrator's Guide to understand the following concepts for Oracle WebLogicServer:

• Oracle WebLogic Server domains
• Managed Servers and the Administration Server

During installation, the applications for a single product family are deployed to one Oracle WebLogic Server domain. Within a single domain, an Administration Server hosts the application for Fusion Applications Control, and the Java EE applications for the product family deploy to the Managed Servers. The Managed Servers are grouped together into a cluster for each application of the product family. Figure above shows a domain with an Administration Server and three Managed Servers in clusters. If you want to scale out the Java EE application, you simply add new servers to the cluster. In an Oracle Fusion Applications environment, the domains are predefined so that the product families and their dependencies are always stored in a standardized arrangement.

As an example of greater detail for a product family, Figure 1,1 shows a portion of the domain for the Oracle Fusion Financials product family with an Administration Server and eight Managed Servers in a cluster. The applications are each deployed to a Managed Server within a cluster. In addition to the applications for Oracle Fusion Financials, the domain also contains an Oracle Enterprise Scheduler cluster and a SOA cluster. The Oracle Enterprise Scheduler (ESSAPP) application manages job requests for the product family. The SOA Infrastructure (soa-infra) application hosts the SOA composites for the applications in the product family.

1.1 Oracle WebLogic Server Domain for the Oracle Fusion Financials Family

The Oracle Fusion Applications Oracle home directory (FA_ORACLE_HOME) is located under the APPLICATIONS_BASE/fusionapps directory The /fusionapps directory is an Oracle Fusion Applications Middleware home (FA_MW_HOME). Figure above shows this directory structure.

The Oracle home contains the following subdirectories:

·         /fusionapps/applications/lcm: The life cycle management directory. Contains the patching framework artifacts in the following subdirectories:

o        ../ad/bin: Patching framework software and executables, including C artifacts and configuration scripts, that set the environment and start the corresponding utility.

o        ../ad/java: Java artifacts.

o        ../ad/db/sql: Database artifacts and SQL files.

o        ../ad/lib: Application libraries.

o        ../ad/template: Configuration files or templates delivered and used by the patching framework during configuration activities.

·         /fusionapps/applications/bin: Executables called by Enterprise Scheduler Service jobs.

·         /fusionapps/applications/product_family: Container directory for artifacts specific to a product configuration, for example, /ORACLE/fusionapps/fin.

·         /fusionapps/applications/admin: Patching framework environment properties file (FUSION_env.properties), Oracle Fusion Applications AutoPatch, and the patching logs, reports, and administration files. These files are required by Oracle Fusion Applications Patch Manager.

·         /fusionapps/applications/lib: Applications-specific libraries.

·         /fusionapps/applications/OPatch: Contains the OPatch utility called by Oracle Fusion Applications Patch Manager when patching middleware artifacts.

Fusion Apps Product Family Directory Structures

/fusionapps/applications/product_family/product: Product grouping within a product family. For example, /fusionapps/applications/fin/ar represents the Account Receivables product in the Financials product family.

/db/plsql/: PL/SQL packages and bodies for a given product, for example, .../fin/ar/db/plsql/arp_process_line.pkh.

/db/sql/: SQL scripts for a given product. For example, .../fin/ar/db/sql/ar_ar_rev_rec_typ_type.sql.

/db/data/lba/US/: Product-specific seed data files, striped by Logical Business Area (LBA). Note that sub-directories could exist in the top-level seed data directory because some LBAs can have sub-LBAs. For example, .../fin/ar/db/data/FinArCustomers/US/ArlookupTypeSD.xlf.

/fusionapps/applications/product_family/deploy: Container directory for deployable artifacts, composites, Java EE applications (such as Oracle Application Development Framework and Oracle Enterprise Scheduler Service).

/fusionapps/applications/product_family/security/: Product family directory containing security-related files.

Hope this will help.

Note - I have copied contents from different docs published by oracle to make it easy for beginners.

I have included one post to HCM Topology View to map the above with actual domain
