In a split domain, the application services associated with the primary components of your product bundle run in one domain, and the application services associated with Metadata Manager run in a separate, secondary domain. You can create each domain on the same machine or on separate machines.
For example, your product bundle includes PowerCenter and Metadata Manager. In a split domain, the application services that you use to perform data integration operations with PowerCenter run in the primary domain. Therefore, the primary domain contains a PowerCenter Repository Service and a PowerCenter Integration Service.
The application services that you use to perform metadata extraction with Metadata Manager run in the secondary domain. Therefore, the secondary domain contains a Metadata Manager Service. It also contains a separate PowerCenter Repository Service and PowerCenter Integration Service that support metadata extraction operations but are not used for data integration operations.
When you create a split domain, you must duplicate some repositories. For example, you must create a separate domain configuration repository in each domain. If your product bundle includes PowerCenter and Metadata Manager, you must also create a separate PowerCenter repository in each domain. You must create each repository in a separate database schema.
Your license might limit the application services that you can duplicate and the product components that you run in each domain. For example, if your product bundle includes PowerCenter and Metadata Manager, you cannot run data integration operations in both domains.
