Global Data Services Catalog

Understand the purpose of the Global Data Services catalog and how to plan for its location and availability.

A Global Data Services catalog (GDS catalog) is a repository that stores configuration data for a Global Data Services configuration and all global services provided by that configuration.

A GDS catalog is associated with one and only one GDS configuration. A catalog must reside in an Oracle database, and that database can be either inside or outside the associated GDS configuration. For large-scale GDS configurations, Oracle recommends that the GDS catalog is hosted outside the databases in the GDS configuration. The GDS catalog can be co-hosted along with catalogs of RMAN or Oracle Enterprise Manager.

To enhance the availability of the Global Data Services catalog database, Oracle recommends that you configure the GDS catalog database on high availability technologies such as Oracle RAC, Oracle Data Guard, and Oracle Clusterware.
