Hi Anand,
Download the JDBC driver for your database to a location on the Data Services host system.
Copy the JDBC driver to all locations required by Data Services.
For Oracle and MySQL databases:
<LINK_DIR>\ext\lib
<BIP_INSTALL_DIR>\java\lib\im\<database_type>
database_type is mysql for MySQL, and oracle for Oracle.
<BIP_INSTALL_DIR>\warfiles\webapps\DataServices\WEB-INF\lib
Refresh the JDBC configuration.
Also refer the installation guide for DS for further reference.
