An OLAP Metadata Catalog is a database that consists of 33 tables in which Integration Services stores OLAP models and metaoutlines.
For a complete list of supported RDBMSs, see Oracle Hyperion Enterprise Performance Management System Certification Matrix (http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html)>.
You can run the RDBMS for an OLAP Metadata Catalog on any supported platform as long as you have the ODBC driver and database client software required to connect to the catalog from the computer that runs Essbase Integration Server. You can also run the RDBMS for the relational data source that you use to create OLAP models and build metaoutlines on any supported platform, if you have the ODBC driver and database client software required to access the data source. For a detailed matrix of specifically supported databases and ODBC drivers, see Oracle Hyperion Enterprise Performance Management System Certification Matrix (http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html)>.
The RDBMS for the OLAP Metadata Catalog can be different from the RDBMS for the relational data source, and the platforms for the two RDBMSs do not need to be the same.
You can have more than one OLAP Metadata Catalog and, by using the XML Import/Export utility, you can move OLAP models and metaoutlines from one OLAP Metadata Catalog to another OLAP Metadata Catalog.
