The following configurations have been performed:

• ODI Topology - Data Server definition:

            JDBC Driver: com.amazon.redshift.jdbc42.Driver
            JDBC URL: jdbc:redshift://[AmazonAWS test URL]:5439/testdb?ssl=true&sslmode=verify-full

• The driver jar file was added in the below locations and WebLogic was restarted - based on <Document 2023446.1> and the Oracle documentation.
