Today modern IT world is full of complex IT landscapes including different systems, apps, and multiple platforms. Most of these operate on-cloud, the latest IT trend, and some of them still work on-premise. To bring the complexities of these platforms down, there is a need to integrate with cloud platforms, mobile-based apps, etc. in one place. This eases the process of integration with other apps to operate business processes smoothly. Oracle SOA framework brings flexibility to the organization’s activities, connecting on-premise and cloud deployments together.
In this blog, we are going to explore the things behind BPEL concepts of the Oracle SOA framework.
SOA framework stands as a middleware platform in the IT market that makes it easier to integrate complex apps. There are many things to know about the BPEL concept and its uses. They mainly involve in building business processes and support services.
Before we start to know the concept of BPEL and its various activities in business. Let us have a brief understanding of Oracle SOA.
What is Oracle SOA
The Oracle SOA Suite is a platform that allows developers to create and develop services and manage them. Further, these services are applicable to business processes along with complex apps. Also, business entities can evolve this architecture easily using the various pluggable components of the Oracle SOA Suite.
At present, we have the Oracle SOA Suite 12c version, which was released in 2014. This is a software suite that helps to develop, deploy, and manage various integrations through SOA architecture. Hence, the quick start version of this software suite is the Oracle SOA Suite 12.2.1.3.0 is useful for cloud integrations.
Moreover, the Oracle SOA emerges with the intention to meet business goals. Such as infrastructure flexibility, integrations, enhanced apps, and minimize costs of operations. The following benefits can SOA suite 12c provides to any user.
Mainly, minimizes the costs of time to market for the latest project integrations.
Reduce complexities; effectively manage the latest technology changes and business needs.
To provide high availability and scalability of the business infrastructure.
Also, it provides complete solution observation through root-cause analysis.

Why do you need Oracle SOA?
Many IT firms face a great challenge while taking an array of software systems that might be compatible with other platforms. Also, customers access the products and services from different web interfaces and are also a part of the supply chain platform. In this space, it needs to reduce the cost and time consumption.
Hence, to meet these demands frequently, many IT firms try to find out solutions.
Today, most technologists adopted Oracle SOA because of the increasing demand for software services globally. This concept also influences technology very much. Moreover, these various software services are also provided through the internet. This may require virtual interfaces to provide such service online.
There are a few benefits also of using the services, such as:
Many large apps may have information issues that cannot be readily available for exchange. Hence, the software services are fine-grained and provide a filtered and better information flow across the organization.
SOA is very less expensive compared to other integration apps available.
It offers great viability of the business information to the users, which in return increase the business value.
The software supporting services makes the business operations rely on them.
Moreover, it makes it easier to change a software architecture based on services. It also enhances the business benefits and helps to avoid unnecessary penalties.
BPEL Environment
BPEL refers to Business Process Engineering Language as a type of technology. This is useful to create programs within SOA architecture. Moreover, it helps to perform business processes through web services. The BPEL in the Oracle SOA environment enables the easiest way to compose different web services into the business processes.
Generally, BPEL uses the XML-based language that supports the Web Services technology stack. This technology stack also includes the following: SOAP, WSDL, WS-Coordination and Transaction, etc.
Further, BPEL is a combination of two earlier languages like - XLANG, and WSFL (Web Services Flow Language). WSFL is the outcome of IBM Inc. and includes the concepts of directed graphs. On the other hand, XLANG is developed by Microsoft and is a block-structured language. Hence, BPEL is inclusive of both concepts and offers a rich vocabulary of descriptions for various business activities and processes.
In a large enterprise, BPEL is useful for regulated enterprise application integration. Further, it also extends to the earlier separated systems. The concept also makes it easier for two different enterprises to effectively integrate with other business partners.
The BPEL concept within Oracle SOA is helpful to energize the enterprises to define further business processes clearly. This, in return, leads to business process optimization, reengineering, etc. Along with this, it enables them to apply appropriate business processes.
Hence, this is a key technology element for the enterprise business that opens through Web Services. The importance of BPEL increases with the enhanced usage of Web Services in the business sector.

A brief note on Web Services
Web services generally uncover certain operations of some apps or IT systems. They also involve in the integration of several underlying apps and their functions.
These web services can also combine in two different ways: Choreography and Orchestration.
The orchestration process is general used in private business processes. Here, a central process controls the Web Services involved and coordinates the performance of various operations on the Web Services. They are mainly included within the operation.
The Choreography is, in the contrast, doesn’t depend on the central coordinator like Orchestration. Here, each Web service is acquainted with when to perform operations and with whom it should interact.
But from the corner of creating Web Services for business processes, Orchestration offers a good benefit over the Choreography. The following are the benefits:
- There is a central coordinator who manages the component processes centrally.
- Also, Web services can be incorporated into a large business process without their consent.
- Whenever a fault occurs, there will be alternate scenarios to put in place.
Hence, these are the well-known benefits of the BPEL process.
How to add a BPEL Service Process Component
The following steps will help to understand the process of component addition.
Go to - Application Navigator- select File from the menu, select New, the Applications, SOA Application.
Here, it will start the Create SOA Application wizard.
Then, go to the Application Name dialog, now enter the application name in the space Application Name field.
Now, within the Directory field, enter a directory path, here we need to create the SOA composite application and project.
Then click on the Next.
Later, enter the Project Name in the field given in the dialog box - Project Name.
Again, click the Next button.
Then come to the Project SOA Settings dialog box, and select the Composite with the BPEL Process option there.
Finally, click on the Finish button to end the entire process.
In this way, there is a step-by-step process involved in the growth of a business process. Furthermore, the Oracle BPEL process manager offers various options. These are useful for auditing, managing, debugging, and deploying BPEL processes smoothly.
Files of BPEL process
The following types of files are included in the Oracle SOA BPEL process.
Composite.xml −
This file defines the complete complex convention of services, service components, references, wires, etc.
.BPEL −
The BPEL file includes the set of activities that are added to the process.
.ComponentType −
The componentType file defines the various services and references for the component under the BPEL process service.
.WSDL −
This file type describes the input/output messages for the BPEL process flow. Along with it, it also defines the client interface and operations support, and other related features.

Conclusion
In this way, we can brief the concepts of BPEL in Oracle SOA. This concept is useful in creating programs within the Oracle SOA structure and is a kind of language. It uses an XML language that supports Web Services. These web services are generally involved in the integration of various underlying apps, including their other functions. Also, these services will help in the creation of business processes well with good support.
