Hi Rohit,
as already assumed above, the newer driver has a different namespacing for its classes.
Please try the “com.teradata.jdbc.TeraConnectionPoolDataSource” instead of “com.ncr.teradata.TeraDataSource”.
Refer to the following links for further informations:
Main Documentation page for Teradata JDBC Driver
Teradata JDBC Driver Users Guide
How to use the Teradata JDBC Driver with WebSphere 9.0 (serves as a sample here where the new DataSource class name is mentioned)
Which JVM version is your IS 10.7 running on (see About-page)?
Latest version of TeraData Driver is version 20, which requires at least JVM 8, while it is no longer compatible with JVM 7. See Overview section in the first mentioned link above.
Remember, that with TeraData driver version 17.x the tdgssconfig jar is no longer needed and should be removed from the classpath.
Regards,
Holger
