Hi Sri,
You can download the below Redbooks from
www.redbooks.ibm.com
Cross-Platform DB2 Stored Procedures: Building and Debugging SG24-5485-01
Setup of the DB2 Application Development Environment for Stored Procedures, REDP-0183-00
Up and Running with DB2 for Linux, SG24-6899-00
I don't know much about DB2 application development however I am sure these would help you in your quest.
