PROBLEM : DB2 Server and Client both 64 bit Products And WCS Product is 32 Bit Product, So JDBC Drivers are Type 2 and Type 4
WCS is not able to communicate with DB2 Server through DB2 Client

SOLUTION : 1. We need to Install 32 bit Client Product  OR
           2. We can set the LD_LIBRARY_PATH on Client System. Before set check the current LD_LIBRARY_PATH "echo $LD_LIBRARY_PATH"
  Output : /opt/IBM/db2/V9.7/lib32:/opt/IBM/WebSphere/CommerceServer70/bin:/home/rilsinst/sqllib/lib64:/home/rilsinst/sqllib/lib32
Then set the below path on Client System.
  LD_LIBRARY_PATH=/opt/IBM/WebSphere/CommerceServer70/bin:/home/rilsinst/sqllib/lib64:/home/rilsinst/sqllib/lib32
