Oracle BPEL Process Manager 10.1.2.0.x Quick Start Tutorial
Describes how BPEL and the Oracle BPEL Process Manager facilitate development of SOA applications through composing synchronous and asynchronous services into end-to-end, standard BPEL process flows. ...
Making web services work is a 2-step process. First you publish your services and then
you compose, or orchestrate, them into business flows. Publishing a service means taking
a function within an existing application or system and making it available in a standard
way, while orchestration is composing multiple services into an end-to-end business
process. The Web services standards, including WSDL, XML and SOAP, have emerged
as an effective and highly interoperable platform for publishing services. In addition, high performance binding frameworks allow enterprises to access legacy systems and native
Java code without necessarily having to wrap them in a SOAP interface.
The BPEL Designer provides a graphical and user-friendly way to build BPEL
processes. What is unique about the Oracle BPEL Designer is that it uses BPEL as its
native format. This means that processes built with the Designer are portable and in
addition it enables developers to view and modify the BPEL source at any time.
The core BPEL engine provides the most mature, scalable and robust implementation of
a BPEL server available today. The Oracle BPEL Process Manager executes standard
BPEL processes and provides a â dehydrationâ capability so that the state of long-running
flows is automatically maintained in a database, enabling clustering for both fail-over and
scalability. The BPEL Server leverages an underlying J2EE application server, with
support for most major commercial application servers and a bundled version available.
The built-in integration services enable developers to easily leverage advanced
connectivity and transformation capabilities from standard BPEL processes. These
capabilities include support for XSLT and XQuery transformation as well as bindings to
hundreds of legacy systems through JCA adapters and native protocols. Human
Workflow is provided as a built-in BPEL service to enable the integration of people and
manual tasks into BPEL flows. The JDeveloper BPEL Designer provides wizards to build
these complex workflows and a simple GUI to map transformations.
