When you create the Metadata Manager Service, you can associate it with the following application services:
PowerCenter Integration Service
When you load metadata into the Metadata Manager warehouse, the Metadata Manager Service connects to the PowerCenter Integration Service. The PowerCenter Integration Service runs workflows in the PowerCenter repository to read from metadata sources and load metadata into the Metadata Manager warehouse. When you create the Metadata Manager Service, you provide the name of the PowerCenter Integration Service.
PowerCenter Repository Service
The Metadata Manager Service connects to the PowerCenter Repository Service to access metadata objects in the PowerCenter repository. The PowerCenter Integration Service uses the metadata objects to load metadata into the Metadata Manager warehouse. The metadata objects include sources, targets, sessions, and workflows. The Metadata Manager Service determines the associated PowerCenter Repository Service based on the PowerCenter Integration Service associated with the Metadata Manager Service.
