Configure Auto-Recovery in Oracle SOA Suite by Danilo Schmiedel

February 9, 2014 Leave a comment

Oracle SOA Suite 11g has some great features to recover faulted instances automatically. When a BPEL process flow errors out, it is retried with all its invocations. This is undesirable in some cases. For example if re-calling a composite results in duplicated data, data have been changed before the recovery is planned to be executed or you do not want to create too many composite instances in order to save the space in your SOAINFRA-schema. See below the different places where automatic recoveries are configured / disabled.
1) Change RecurringScheduleConfig (see also the screenshot below)

  • Right-click soa-infra (SOA_cluster_name)
  • Choose SOA Administration > BPEL Properties
  • Click “More BPEL Configuration Properties”
  • Click “Recovery Config”
  • Change values for RecurringScheduleConfig
    • maxMessageRaiseSize = 0
    • startWindowTime = 00:00
    • stopWindowTime = 00:00

Event-Driven SOA part of Industrial SOA series

February 7, 2014 Leave a comment

imgAbstract: If we consider real companies and their business transactions, we see that the real world is not really service-driven at all, but much more event-driven. A new customer is created in the system, a new car reservation is made, a vehicle is returned or needs to be taken to the shop. All of these "functions" can be supported by services, but often also by precisely defined process chains.

However, complex business processes can rarely be automated "in one piece," as the real exceptions and dependencies of diverse business processes are highly dynamic. That brings us to the point where the concept of "event" becomes useful in our architectures. In this article, we therefore want to shine light on event-driven architectures and tie them into our current argumentation chains in SOA.

Dealing with Business Events
Most companies now collect business-relevant information by aggregating available data. As a rule, this is in the domain of data warehouses which condense information a follow-up to preceding events. Here the focus is directly on the data and not on the process information, which is actually much more interesting. We miss out on the ability to process business information in near-realtime, which would allow the company management to react much more quickly to events as they occur. The discipline of business intelligence is developing rapidly in order to take this issue into account. In the following, we want to consider the underlying mechanisms, or the events which allow faster reactions to important changes. Read the complete article here.

Norway Post Improves Customer Service and Saves Major Annual Costs by Boosting Call-Center Productivity thanks to Accenture and Capgemini

February 6, 2014 Leave a comment

Norway Post AS, founded in 1647, is the Norwegian postal service. The company, owned by the Norwegian Ministry of Transport and Communications, manages mail distribution throughout the country and has businesses in other parts of the Nordic region. In 2002, Norway Post changed its corporate structure to become a joint-stock company in preparation for Norwegian postal market deregulation.

Challenges

  • Streamline operations and reduce costs, including IT expenses for the company’s five customer-service call centers in response to shrinking revenues, as the volume of mail has fallen 40% since 1999
  • Enable customer-service representatives to more efficiently and accurately help customers, including answering questions, tracking missing or delayed mail, and making compensation payments
  • Increase customer and employee satisfaction
  • Expand insight into customer behavior and preferences and use the information to improve service and product offerings
  • Create a solution that is easy to roll out to new organizations as Norway Post acquires additional companies.

Oracle solution

  • Implemented Oracle SOA Suite and Oracle WebLogic Suite to integrate the company’s cloud-based, Salesforce.com, customer-relationship management (CRM) system with its customer-service call centers’ on-premise, back-end systems – such as those used to manage customer lists, addresses, financial and procurement systems, and a mail-tracking solution – so employees can access them from a single, user interface and deliver faster and more thorough assistance
  • Cut time needed to access customer and tracking information from back-office systems – improving customer and employee satisfaction
  • Saved major costs annually, thanks to improved call-center productivity
  • Achieved additional significant savings in time and effort and improved data quality by ensuring that information changes made in the integrated, back-end system are automatically synchronized in all other integrated systems, thanks to Oracle SOA Suite
  • Expanded customer insight through more efficient customer-service call centers, enabled by cloud integration – which improves services and increases customer satisfaction and the company’s profitability
  • Created a solution that makes it easy for companies that Norway Post acquires to implement – accelerating time to value
  • Eliminated previous skepticism toward integration between cloud computing and on-premise back-end systems to facilitate more benefits from this type of solution by using it in other parts of the organization

Manual Recovery Mechanisms in SOA Suite and AIA by Shreenidhi Raghuram

January 28, 2014 Leave a comment

Introduction

Integration flows can fail at run-time with a variety of errors. The cause of these failures could be either Business errors or System errors.

When Synchronous Integration Flows fail, they are restarted from the beginning. On the other hand, Asynchronous Integration flows when they error can potentially be resubmitted/recovered from designated/pre-configured milestones within the flow. These milestones could be persistence points like queues topics or database tables, where the state of the flow was last persisted. Recovery is a mechanism whereby a faulted Asynchronous Flow can be rerun from such a persistence milestone.

1The SOA Suite 11g and AIA products provides various Automated and Manual recovery mechanisms to recover from asynchronous fault scenarios. They differ based on the SOA component that encounters the error. For instance, recovering from a BPEL fault may be quite different than recovering from a Resequencer fault. In this blog, we look at the various Manual Recovery mechanisms and options available to an end user. Manual recovery mechanisms require an Admin user to take appropriate action on the faulted instance from the Oracle Enterprise Manager Fusion Middleware Control [EM FMWC Console].

The intention of this blog is to provide a quick reference for Manual Recovery of Faults within the SOA and AIA contexts. It aims to present some of the valuable information regarding Manual recovery in one place. These are currently available across many sources such as SOA Developers Guide, SOA Admin Guide, AIAFP Developers Guide and AIAFP Infrastructure and Utilities Guide.

Next we look at the various Manual recovery mechanisms available in SOA Suite 11g and AIA, starting with the BPEL Message Recovery.

BPEL Message Recovery

To understand the BPEL Message Recovery, let us briefly look into how BPEL Service engine performs asynchronous processing. Asynchronous BPEL processes use an intermediate Delivery Store in the SOA Infrastructure Database to store the incoming request. The message is then picked up and further BPEL processing happens in an Invoke Thread.

The Invoke Thread is one among the free threads from the ‘Invoke Thread Pool’ configured for BPEL Service Engine. The processing of the message from the delivery Store onwards until the next dehydration in the BPEL process or the next commit point in the flow constitutes a transaction. Figure below shows at a high level the Asynchronous request handling by BPEL Invoke Thread. Read the complete article here.

BPEL, retrieving the validate activity fault message by Eric Elzinga

January 27, 2014 Leave a comment

The ‘Validate’ activity in Oracle BPEL gives us the functionality to validate variables again schema definitions.

When using it in your bpel process you will get a nice informative message in the ‘Flow trace’.

validate1

When you are using some generic error hospital functionality you also want this message to be available in there.

First try would be, add a Scope around the activity and catch the ‘invalidVariables’ System Fault.

When using a getFaultString on the fault variable or after assigning it to your own fault variable you will see the fault stack will be empty.

validate2

SOA Suite 11g: Consuming web service which enforce security policies on their WSDL files by esentri

January 25, 2014 Leave a comment

Concrete WSDL VersionThe basic principle behind a Service Oriented Architecture is to orchestrate functional building blocks, primarily web services, in order to achieve a solution which fulfills the given requirements. In order to create a robust solution using Oracle SOA Suite several best practices emerged, one being decoupling web services in order to overcome dependencies during server/composite startup. A general approach for achieving this best practice is to use abstract and concrete WSDLs in combination.

An example for a working reference definition within the composite could look like follows:

<reference name="FooBarService" ui:wsdlLocation="oramds:/apps/com/foo/v1/bar.wsdl">

  <interface.wsdl interface="http://foo.com/BarService#wsdl.interface(BarService)"/&gt;

  <binding.ws port="http://foo.com/BarService#wsdl.endpoint(BarService/FooBarEndpoint)&quot;

    soapVersion="1.1"

    location="http://foo.com:7001/soa-infra/services/foo/bar/FooBarEndpoint?WSDL"&gt;

  </binding.ws>

</reference>

On a recent project we ran into some problems while implementing this best practice as some web services we had to consume not only protected their operations but also their WSDLs using basic authentication web security. Although we were able to access the operations by providing the security credentials within WebLogic Server using the Credential Store Framework (CSF), the solution never managed to successfully access the secured WSDL files.

After trying several approaches to overcome this problem, we implemented a workaround by storing an abstract WSDL within the shared MDS project as well as a concrete WSDL within the composite project in order to access the affected web services. We stored the concrete WSDLs within a wsdl folder in the project. Read the complete article here.

A Roadmap for SOA Development and Delivery by Mark Nelson

January 23, 2014 Leave a comment

This post is part of a series on SOA Development and Delivery.

In this post I will present a roadmap and a target state for SOA Development and Delivery.  This will serve as the basis for an extended open ‘proof of concept’ that we will work through together, over a series of posts, to implement and prove this approach.

Let’s talk first about our target state – the goal we want to achieve, then we will come back and look at the steps on the journey.

The Vision – Continuous Delivery

Continuous Delivery is a set of practices, supported by tools and automation, that is focused on answering the question: ‘How much risk is associated with deploying this new change into production?’

It involves automation of everything that needs to happen between a developer committing a change and the release of the software including that change into production, including:

  • building the software
  • testing the software, and
  • managing the configuration of the environments

The outcome that we want to achieve, is that we can automate all of our:

  • build
  • component-level test
  • environment provisioning (for development, test and production environments), and
  • acceptance test
