PROJECTS:EAI Migration Project
Large scale project which involves migration of Java caps integration interfaces to Oracle SOA platform by

* Thorough analysis of Java caps code To migrate to SOA platform
* Creation of high Level and technical documents based on existing Java caps code.
* Developed BPEL processes using DB Adapter, File Adapter, JMS Adapter, and FTP
Adapter
* Developed custom Web Services using Oracle JDeveloper
* BPEL Error handling was implemented for handling the faults in BPEL Processes
* Business faults were handled using the catch, catchall, throw, compensation and
compensation handler activities. The system faults were handled by defining fault-
policies in the fault management framework

Key Interfaces
Payment Adjustments
This was a file to file interface implemented in BPEL.The challenging part of the interface was

successfully processed data has to be archived and error file has to be moved to error location
respectively. An email notification has to be send with a relevant status message.
Role and Responsibility:
* Responsible for the Design and Developement of the Interface which connects
between Different File system using Oracle BPEL platform
* Created FTP adapters in Jdeveloper to connect source and target file systems
* Done compex validations using various string functions and in bulit BPEL functions
* Done Sever level tuning to meet the requirements
* Designed BPEL flow to meet the requirements efficantly
* Implemented fault handling, fault retry and rejection in BPEL
Billing Adjustments
This was a file to file interface implemented in BPEL.The challenging part of the interface was

Extract Customer Info
The interface requirement was to fetch large number of records from oracle database and to
insert in to Microsoft SQL server. The Challenging part of the interface was to handle large
number of records in minimum processing time. I was responsible for design and
development for the interface and could accomplish client requirement successfully.
Role and Responsibility:

Eclipse to make use for OSB platform
* Created XQUERY and tuned it in such a way that it could handle large data
transformations with maximum efficiancy
* Done Sever level tuning to meet the requirements
* Designed proxy service message flow and business service to meet the requirements
* Implemented fault handling, fault retry and rejection in OSB
