What is AIA

Oracle’s approach to implementing SOA Tools

● Process model decomposition -> Project Lifecycle Workbench

● Service construction -> JDeveloper plug-in● Deployment plan generation● Deployment

Canonical Model with XSD’s and WSDL’s Error Hospital for Business and Systems Faults Testing and simulation of Services

AIA Foundation Pack and PIPs

AIA Example

An AIA process is not 1 composite with some service components like BPEL, Mediator and Human Tasks

AIA Process steps

Let’s build an AIA process by following the next steps Define a new Project, Business Tasks and Service Solution Components Identifying your Enterprise B. Object(XSD) and Services (WSDL) Building Composites

● Adapters● Application Business Connector Services (ABCS)● Enterprise Business Services (EBS)● Enterprise Business Flow (EBF)

Annotate your Composites Harvest your Composites to Lifecycle Workbench Bill of Material (BOM) Generate a Deployment Plan from the generated BOM Deployment of the Resource Adapters, Composites & AIA Configuration

Testing your AIA process with the Composite Application Validation System (CAVS) Error Hospital for System and Business Faults

Creating a new Project

url = http://xxxx/AIA/faces/aiaHomeLogin.jspxGo to the Project Lifecycle Workbench application

Add a Project with Business Tasks

Define a new Project with one or more Business Tasks

Service Solution Components

Forces you to think about your process and split up the project in SOA Composites

Enterprise Business Object EBO

AIA has many pre-defined business data object Identify and optional extend the XSDs you want to use

Enterprise Business Message EBM

AIA contains an EBM for every Enterprise Business Object EBMs are the messages that are exchanged between two

applications Has XSD elements for Operation input and response Has an EBM Header for tracing and routing information

Enterprise Business Service EBS

Has many Web service definitions for performing a business task Identify the Service Operations you want to use

Building Composites

Start from the Destination Application -> Source Application● This way you can deploy and test your composite with SoapUI● Have a service definition for the next composite who use this

WSDL as a reference

Application Adapters

Choose your application adapter, like a DB or AQ/JMS Adapter Expose this Adapter as a Service with your own Application XSD and

WSDL Add the adapter WSDL and XSD to the AIA DB MDS

Generated DB adapter XSD

Own ApplicationXSD

Transformation

Application Business Connector Services

Generated by the AIA Service Constructor● Always BPEL when Stateful or Asynchronous

Tasks ABCS● Validation● Transformations like message translation, content

enrichment● Invoking application operations● Error handling● Security

ABCS Creation (Provider side)

Start the AIA Service Constructor in JDeveloper Connect to the AIA Lifecycle Workbench and select the

ABCS from the Service Solution Components

ABCS Service

Select the EBS WSDL from the MDS connection ( Resource Palette) Choose the operation

ABCS Reference

Enable Error handling Enable Testing Simulation Select the Application Adapter WSDL

ABCS Composite

EBS Service with the QueryPerson operation, a BPEL component and an Application Adapter & AIA Error handling as Reference

ABCS BPEL Flow

Read and Fill the EBM HeaderAdd some Tracing information

Set the endpoint to Application Adapter or Test Simulator

ABCS Exception Handling

Can handle Adapter failures

Enterprise Business Services

Can be a Mediator or an OSB Proxy

Enterprise Business Flow

Implements the Business activity Can be BPM or BPEL Long running Can contain Human Tasks & Business

Rules Raise Business Faults to Error Hospital Calls EBS Services

EBF Composite

Has EBS references and is called by an EBS Composite Has an AIA Error handler reference for Business Faults

EBF Business Fault Example

Check if an Employee already exists if so raise a Business Fault

Annotate your Composites

Add annotations to Composite, Services and References elements ( composite.xml )

Will be used by the Harvester utility This data will be used in the deployment plan generator

Reference Annotations

Added to the AIA DB Resource Adapter

Harvester

Read the Composites Annotations Optionally Publish to Oracle Enterprise Repository Updates the project service components (Lifecycle workbench)

Create HarvesterSetting.xml and start AIAHarvest.bat

Bills of Materials

Go to the AIA Lifecycle Workbench Generate the Bill of Materials of your project

Export Bills of Materials

Optional -> change or add composites

Export BOM.xml

Generate Deployment Plan

Start the ANT Deployment Plan Generator

( AIADeploymentPlanGenerator.xml )● Bill of Materials ( BOM.xml ) will be used as input

Deployment Plan

A XML which is read by the ANT Deployment Utility Can create, configure or deploy the following:● JDBC Datasources● JMS Resources● MDS update● Start & shutdown WLS Server● Resource Adapters AQ, DB, JMS● EAR & WARS● Composites

See my blog for more information http://biemond.blogspot.com/2011/02/do-your-soa-deployments-configuration.html

Deployment configuration

JDBC Datasource

JMS Queue

Update MDS

Shutdown Managed ServerAdd an entry to the DBResource adapter

Deploy a WAR

Deploy a Composite

Enterprise Manager & AIA

With SOA Suite 11g you can still follow the instance through all the AIA Composites

Error Handling

Two types of faults● System / Adapter Faults which are captured by

the ABCS ( Generated by the JDeveloper Service Constructor)

● Business Faults can be thrown in the EBF Composite (Developer Task)

Error Handling - Configuration

Defined in the AIAConfigurationProperties.xml located in the MDS

Enabling Tracing Define your own error handling class Enable BPM Worklist Enable Email notification

Error Handling - Notifications

• Go to http://xxxx/AIA/faces/aiaHomeLogin.jspx• Click on the Go button in the Setup window• Configure actions for a particular fault

Error Handling - BPM Worklist

Business and System Faultsshown in the BPM Worklist Application which has an ADF Task Flow for the Task details

Composite Application Validation System

Go to http://xxxx/AIA/faces/aiaHomeLogin.jspx Press the Go button in the CAVS window

What can CAVS do for you Create tests and validate responses Simulate Adapter services in ABCS Group Tests Combine Test and Simulators with Routing Import / Export Definitions

For more information see my blogpost http://biemond.blogspot.com/2011/03/test-your-services-with-aia-cavs.html

CAVS Definitions

CAVS Test

Load the WSDL and select the operation Define 1 or more Requests Define 1 or more Responses and Generate Xpath Add Expected Node Values

CAVS Simulator

Define requests, Generate XPath and set a unique identifier so the matching response can be returned

Provide the matching Response

Add Simulator on an ABCS reference

CAVS Routing

Activates CAVS Simulators Can be used in a CAVS Test

Conclusion

AIA is a lot of work and it can really help you in building complete and reliable SOA processes● Complete Deployment framework● A lot of XSDs and WSDLs you can use● Error Hospital which handles Business and Adapters Fault● Testing and simulation of Services

Build you own PIP build on AIA and sell it for big Money to Oracle
