Thnx for this suggestion.This is exactly what needs to be done.Looks like th
e DB2 JNI calls are not getting executed properly hence the UnstatisfiedLink
 error. and thats happening because of incorrect setup of LD_LIBRARY_PATH. I
 will have to fix that wher
e this path is getting corrupt.I got this info after getting a javacore file
 by issues kill-3 <pid>
Thnx for your inputs.will try this out too.
