in-short a proper guideline.......

start from here for what all You might want to know about certifications
http://www-03.ibm.com/certify/
and proceed to
Certifications by product - List of certification product categories
http://www-03.ibm.com/certify/certs/index.shtml
and then to
IBM Information Management
http://www-03.ibm.com/certify/certs/dm_index.shtml

as far as the price is concerned why should we waste time researching? it' s not us who has to take the exam
and after all this is a technical help forum, not a shopping help one

"IBM DB2 CERTIFICATION"
and the very first link returned was ...

how do You expect to pass any certification if you do not even have the basic skills of finding the info Yourself
or are You just lazy ???
