Cloud Adapter for Salesforce.com – Understanding What It Does & How You Benefit by ITC

January 19, 2015 1 Comment

Starting in the 1990’s it became standard operating procedure in all large and even mid-sized companies to use an ERP system such as Oracle E-Business Suite to manage business processes like Order Management, Accounting System or Supply Chain Management, along with the complete sales and revenue cycle from quote-to-order and order-to-cash.

However, as recently as only a half-decade ago, those same companies either ran CRM systems completely independently of those ERP solutions or they scarified high quality CRM functionally for a CRM alternative that was “good enough” but integrated easily with Oracle.
However, this began to change at the beginning of the second decade of the 21st century, as companies began dropping their legacy systems and opting to move to SaaS-based CRM solutions such as SalesForce.com. The attraction of solutions such as Salesforce.com is twofold: first, they offer best of breed functionality; second, the SaaS model makes them very attractive from a total cost of ownership perspective.
However, the downside that Oracle users face when they adopted a SaaS solution such as SalesForce.com was that it didn’t integrate with Oracle E-Business Suite. And this creates problems such as data silos, data scattering, data quality issues and other major inefficiencies related to business process execution. Maintaining your data also becomes a challenge, as data captured across your system must be duplicated to SalesForce.
To overcome these issues and take full advantage of Oracle EBS and SalesForce.com organizations need to achieve a seamless information flow between the two: they need to integrate them. This much has long been obvious. Read the complete article here.

SOA Suite 12c and the OPSS Keystore Service by Adam Desjardin

January 18, 2015 2 Comments

When working with a colleague on a sample SOA 12c project recently I noticed a change in 12c that I had not seen mentioned anywhere yet. In the sample project we were integrating with the Atlassian OnDemand service in order to provision users for Confluence and JIRA. The integration is performed using a SOAP service over SSL. In this situation, like at many of our customers, we needed to import additional trusted certificates into the trust store in order to make the service call over SSL. At many of our customers this is an internal Root CA they use to sign their own certificates for internal use.

When looking at the default settings of the IntegratedServer in JDeveloper 12c we can now see below that it is configured by default to use the OPSS Keystore Service and not a JKS Trust Store.

You can see above that instead of a filesystem URI to a JKS file you now see a kss:// URI. This URI shows that we are using the trust store called "trust" in the system strip of the Keystore Service.

The OPSS Keystore Service is meant to provide a single location for Keystores and Trust stores for all applications running within the Weblogic domain. The only pre-requisite for using the service is that the JRF templates have been applied to your domain, which should be the case for any SOA 12c domain.

Using this service you can now manage all of your certificates through Fusion Middleware Control and WLST. You can navigate to the Security -> Keystore menu under your domain in FMW Control as shown below. Read the complete article here.

SOA Suite 12c New Features: Creating SOA Project Templates for Reusing SOA Composite Designs by Joe Greenwald

January 17, 2015 Leave a comment

In SOA Suite 12c, we create application integrations and business processes designed as services composed of processing logic, data transformation and routing, dynamic business rules and human tasks in the form of XML-based metadata. The graphical representations of these services are created in JDeveloper using its graphical editors. Since these services are composed of individual, separately configurable components, we call this a composite service. Once deployed to and hosted by Oracle SOA Suite, this service looks and acts like any other web service to its clients.
It would be highly productive and desirable to be able to easily create templates for service designs that could be reused across teams and projects. Using quality designs and tested patterns as the starting point for new services speeds up development while also supporting widespread adoption of quality and standards in service design.

SOA Suite 12c automates creation and management of templates of service composites, as well as individual service components. The service project templates we create will be stored and managed in the file-based MDS, so they can easily be shared with other developers.
We have an existing service composite that we would like to clone or use as the basis of new service composite. Once we create the new service based on the template, we’ll be able to make modifications to it as needed.
Here is the current Service:
The service exposes a web service entry point, OrderStatus whose interface is implemented by convertWS mediator. ConvertWS transforms the incoming message as needed and routes the message to be processed by GetStatus, a Business Process Execution Logic (BPEL)-based component. The BPEL process accesses the database through the database adapter, OrderDB, to check order status and then writes the status to a flat file via the file adapter, writeQA.

BPM 12c Gateways (Part 2 of 5): Inclusive Gateway by Antonis Antoniou

January 16, 2015 Leave a comment

The inclusive gateway, just like the exclusive gateway, enables you to split your process into two or more paths. The intrinsic difference between an exclusive gateway and an inclusive gateway is that in an exclusive gateway, the process only continues down one of several paths (if multiple outgoing sequence flows are present) while in an inclusive gateway a process will follow all conditional paths whose expressions are evaluated to true.

Furthermore, in an inclusive gateway a process will only follow the default path only if no conditional expressions evaluate to true. Because of this particular characteristic the notation of an inclusive gateway consist of a split and a merge inclusive gateway.

An inclusive gateway can consist multiple outgoing conditional sequence flows for an inclusive gateway split. However, an inclusive gateway must define a default sequence flow. All conditional expressions that evaluate to true are executed; otherwise the default sequence flow is executed.

At run time, the BPM engine generates a token for each conditional sequence that evaluates to true. If none of the conditional sequence flows evaluate to true then a token gets generated for the default sequence flow. The process will pause and will resume only when all tokens have reached the merge

So let’s see how you can use an inclusive gateway in a process. I have created a new BPM application using the "BPM Application" JDeveloper template and in the "Project SOA Settings" step i have selected "Composite with BPMN Process". Read the complete article here.

SOA Suite 11g and 12c: Determining composite dependencies to the level of operations by Maarten Smeets

January 16, 2015 Leave a comment

In large companies, often there are many services and dependencies between services. It is important to track service dependencies in order to for example estimate the impact of changes. Design documents or architecture views can be used for this but as everybody knows, there is often a gap between theory and practice (design and implementation).

In this blog post I provide code to determine dependencies between composites to the level of operation calls. In order to achieve this, I’ll parse the composite.xml files, JCA files (used by adapters) and also the BPEL and BPMN files in order to determine the operations. The script can be used for SOA Suite 11g and 12c composites.

The above picture shows different parts of which a composite is composed and how they are linked. The script first determines references. The references specify which external services are called. Then by using wires, the relevant components are determined. Based on the component type, specific logic is used to extract the operation. Not shown in this picture is how database dependencies can also be determined by the script by parsing the JCA files specified in the reference. If you’re in a hurry, you can go to the ‘Executing the script’ part directly and skip the explanation.

Composites

This blog will focus on composites (which can contain components like BPEL and BPM) using the shared SOA infrastructure and not on for example the Service Bus. Composites use the Software Component Architecture (http://www.oasis-opencsa.org/sca) to wire different components together in a consistent way. Oracle uses XML files to describe composites, components and references. These files can easily be parsed and correlated.

Introduction composite.xml

The main file describing a composite is the composite.xml file. Below is a small sample of a HelloWorld composite containing a single component, a BPEL process. Read the complete article here.
