INTRODUCTION
In computing, BPEL
(Business Process Execution Language), is a business process language,
serialized in XML which defines a notation for specifying business process
behaviour based on Web Services. It aims to allow existing web services to be
orchestrated into composite services, focussing on business process logic.
The Oracle BPEL Process
Manager is a run-time environment for BPEL processes. It executes standard BPEL processes and
provides a Dehydration capability so that the state of long-running
flows is automatically maintained in a database, enabling clustering for both
fail-over and scalability purposes. In order to provide this capability, an Oracle
Database or an Oracle Application Server is required as a
dehydration store for Oracle BPEL Manager in MS Windows operating systems.
Description of the underlying computing-related problem
This project will adhere
to the fact that at this time, non-Oracle databases are not supported as Oracle
BPEL Process dehydration stores. In
Oracle BPEL Process Manager Installation Guide,
it is stated[1]
that “At this time, non-Oracle databases are not supported as Oracle
BPEL Process Manager dehydration stores. This installation option is reserved
for future use.”
The following table describes the databases that are officially
supported from Oracle:
•
Oracle Database Lite
|
•
Oracle Database 10g
|
•
Oracle9i Database release 9.2.0.5.0 or later
|
• MSSQL Server
|
Scope of the project
The project will
explore the underlying technology of Oracle's BPEL Server by creating and
deploying several BPEL processes. BPEL's dehydration feature will be activated
within OracleLite environment and its mechanics will be investigated with a
view to test the possibility of integration of Oracle's BPEL Process Manager
with an existing open-source database.
Project problem and objectives
When all of the above have
completed successfully, the project shall investigate the possibility
of integration of the Oracle's BPEL Process Manager with an existing open-source database and in particular Fyracle. The specific database is a special version of the open source Firebird database, and is chosen as it supports Oracle PL/SQL syntax, in order to ease porting of Oracle applications
to open source4.

Finally,
the project shall set the foundations of further exploration of
the BPEL technology and its integration
with the open-source community.
Definition of project hypotheses/questions
The project shall give answers to the following question :
Will the dehydration feature of
Oracle BPEL Process Manager work with an open-source database?
