Oracle AIA Overview

Oracle Application Integration Architecture (AIA) is a complete integration solution for orchestrating agile, user-centric, business processes across enterprise applications. AIA offers prebuilt solutions at the data, process, and user interface levels delivering a complete process solution to business end users. All of the AIA components are designed to work together in a mix-and-match fashion. They are built for configurability, ultimately helping to lower IT costs and the burden of building, extending, and maintaining integrations.

Powered by Oracle Fusion Middleware, AIA enables organizations to use the applications of their choice and create Composite Business Processes (CBPs) following these guiding principles that define the ground rules for development, maintenance, and usage of a service-oriented architecture (SOA):

· Reuse, granularity, modularity, compose ability, componentization, and interoperability.

· Standards-compliance (both common and industry-specific).

· Service identification and categorization, provisioning and delivery, and monitoring and tracking.

AIA Features

AIA Foundation Packs provide the methodology and framework along with the content that is critical for customers to figure out their integration problems.

Integration Styles

The following sections provide details about each of these integration styles:

Data-centric integration
Integration through native interfaces
Integration through Web services
Reference data query
Process-centric integration

What are AIA Conceptual Services?

AIA Conceptual Services are developed using Oracle Fusion Middleware technologies. They constitute the service portfolio for the SOA implementation and enable the following:

· Reuse, granularity, modularity, composeability, componentization, and interoperability

· Standards-compliance (both common and industry-specific)

· Service identification and categorization, provisioning and delivery, and monitoring and tracking

AIA Conceptual Services are categorized into Process Services, Activity Services, Data Services, Connector Services, and Infrastructure Services.

Before installing the AIA Foundation pack you need to follow the below mention steps.

I assume you have already installed the below mention things.

Oracle 11g R2 Database.
Weblogic 11g.
SOA Suite 11g.
SOA domain configured.

If you have not install the above mention things then you need to check the below mention links.

http://faisal-soa.blogspot.com/2011/11/soa-11g-installation-on-windows-and.html

after installed, I assume SOA / Weblogic / Database is up and running then you need to configure the Node Manager.

Please follow the steps for Node Manager.

Start the Node Manager using the below mention command.

<Middleware_Home>\wlserver_10.3\server\bin\startNodeManager.cmd

Configure / Connect the Server with LocalMachine using the below mention command.

<Middleware_Home>\wlserver_10.3\common\bin\WLST.cmd

nmConnect('weblogic','welcome1','<Server_name>','5556','SOA_domain')

After configured node Manager you need to connect the Admin Server and SOA Server using the below mention command.

nmStart('AdminServer')

nmStart('soa_server1')

Before installing AIA 11g, you need to download the AIA 11g from the below mention link.

Grid Technology Overview

Grid computing combines computers from multiple administrative domains to reach a common goal, to solve a single task and may then disappear just as quickly.

One of the main strategies of grid computing is to use middleware to divide and apportion pieces of a program among several computers, sometimes up to many thousands. Grid computing involves computation in a distributed fashion, which may also involve the aggregation of large-scale cluster computing-based systems.

Oracle Enterprise Manager Grid Control

For managing lots of databases and application servers (according to Oracle Corporation, preferably in a grid solution) one could use the Oracle Enterprise Manager Grid Control. It can manage multiple instances of Oracle deployment platforms; the most recent edition also allows for management and monitoring of other platforms such as Microsoft .NET, Microsoft SQL Server, NetApp Filers, BEA weblogic and others. Partners and IT organizations can build extensions to Oracle Enterprise Manager, and make them available to other Enterprise Manager users via Oracle Enterprise Manager 10g Grid Control Extensions Exchange. System monitoring:

Enterprise Manager provides comprehensive, flexible, easy-to-use monitoring functionality that supports the timely detection and notification of impending IT problems to the intended users. It offers the most comprehensive monitoring from Oracle Database instances to Oracle Real Application Clusters to Oracle Application Server Farms and Clusters. OEM Grid Control comes with a comprehensive set of performance and health metrics that allow monitoring of key components in your environment such as applications, application servers, databases, as well as the back-end components on which they rely, such as hosts, operating systems and storage.

The architecture of the OEM for Grid Control has three distinct components:

the collection agent (Oracle Management Agent or OMA)
the aggregation agent (Oracle Management Server or OMS)
the repository agent (Oracle Management Repository or OMR)

The OMA runs on the target host and collects information on the hardware, operating system, and applications that run on the target. The OMS runs on one or two servers and collects the data generated by the OMAs. The OMS pulls the information from the OMAs and aggregates the collections into the repository. The OMS also acts as the user-interface — by generating web-pages for database administrators to view the status of systems and services. The OMR comprises an instance of the Oracle database that stores the data collected by the OMS. Installers can make the OMR highly available or fault-tolerant by running it on an Oracle RAC instance across multiple nodes.

Key features of OEM Grid Control:

System Monitoring

Managing Groups

Job System

Information Publisher

Compliance Management

Extending Enterprise Manager

Managing Targets

Before starting to install the Oracle Grid you need to download from the below mention link.

http://www.oracle.com/technetwork/oem/grid-control/downloads/winsoft10g-100825.html

Oracle Grid 11.1.0.1.0

Kindly extract the three files into the same folders. if not then you will face the error (figure 1.5)

I assume, you have already installed the below mention items.

Oracle Database (11g R2)

Oracle Weblogic Server. (10.3.2) this version of Weblogic server is compatible with 11g Grid. otherwise you have faced error (figure 1.4)

If not installed, then please go through with the below mention links.

http://faisal-soa.blogspot.com/2012/06/oracle-database-11g-r2-installation.html

Some important prerequisites need to be check before installing Oracle Grid 11g (11.1.0.1.0)

Partitioning option is installed in the database. Otherwise error (figure 1.0)
After installing Oracle 11g Database you need to deactivate the DB control using the below mention command. Otherwise error (figure 1.1)

emca -deconfig dbcontrol db -repos drop

Alter the value of session_cached_cursors must be equal to or greater than 200. otherwise error (figure 1.2)
Alter the value of log_buffer must be equal to or greater than 10485760.
Alter the value of processes must be equal to or greater than 500.
Alter the tablespace size atleast 200 MB. otherwise (figure 1.3)

After applying the above mention changes then you restart the database.

Now we are ready to install the Oracle Grid 11g.

Click on the setup file.
