Changes to data servers

The changes affect Pivotal Greenplum, and SAP BW data server connections.

For information about deprecated or removed data servers, see Cognos Analytics 11.1.x deprecated and removed features.

Connect to an open source Greenplum server using the PostgreSQL JDBC driver

You can use the PostgreSQL JDBC driver to connect to an open source Pivotal Greenplum server.

To create a data server connection to an open source Greenplum server, version 5 or later, use the PostgreSQL JDBC driver and connection editor. When you test the connection in the administration interfaces, the sub-type of Greenplum is displayed when the connection is successful.

To create a data server connection to a proprietary Greenplum server, use the Pivotal Greenplum JDBC driver and connection editor.

SAP BW 7.5 client is required for SAP BW data server connections

The client SAP NetWeaver RFC library 7.20 that was used with previous versions of Cognos Analytics is no longer supported. SAP NetWeaver RFC Library 7.50 is now the supported library.
