To create OLAP models or build metaoutlines, you must connect DB2 OLAP Integration Server to both an OLAP Metadata Catalog and a relational data source. To make these connections, you must first configure each data source by mapping a supported Open Database Connectivity (ODBC) driver to each database. On Windows NT and Windows 2000, configure ODBC drivers using the ODBC Administrator. On AIX, HP-UX, and Solaris, use the odbcconfig utility or edit the odbc.ini file. All configuration of ODBC data sources is done only on the computer that runs Essbase Integration Server.
If a supported ODBC driver is already mapped to the relational data source, you do not need to map it again. In this case, you only need to map a supported ODBC driver to the OLAP Metadata Catalog.
