Hi Vinay,
Control Center was deprecated in DB2 9.7, and was removed from DB2 10.1.
IBM provides the free IBM Data Studio product as the replacement.
Great getting started info here: http://www.ibm.com/developerworks/wikis/display/db2oncampus/FREE+ebook+-+Getting+started+with+IBM+Data+Studio+for+DB2
Hope this helps,
