PowerCenter Repository Service

PowerCenter Repository Service

The PowerCenter Repository Service manages connections to the PowerCenter repository from repository clients. A repository client is any PowerCenter component that connects to the repository. The Repository Service is a separate, multi-threaded process that retrieves, inserts, and updates metadata in the repository database tables. The Repository Service ensures the consistency of metadata in the repository.
The Repository Service accepts connection requests from the following PowerCenter components:
  • PowerCenter Client.
     Create and store mapping metadata and connection object information in the repository with the PowerCenter Designer and Workflow Manager. Retrieve workflow run status information and session logs with the Workflow Monitor. Create folders, organize and secure metadata, and assign permissions to users and groups in the Repository Manager.
  • Command line programs.
     Use command line programs to perform repository metadata administration tasks and service-related functions.
  • PowerCenter Integration Service.
    When you start the PowerCenter Integration Service, the service connects to the repository to schedule workflows. When you run a workflow, the Integration Service retrieves workflow task and mapping metadata from the repository. The Integration Service writes workflow status to the repository.
  • Web Services Hub.
     When you start the Web Services Hub, it connects to the repository to access web-enabled workflows. The Web Services Hub retrieves workflow task and mapping metadata from the repository and writes workflow status to the repository.
  • SAP BW Service
    . Listens for RFC requests from SAP NetWeaver BI and initiates workflows to extract from or load to SAP NetWeaver BI.
You install the Repository Service when you install PowerCenter Services. After you install the PowerCenter Services, you can use Informatica Administrator to manage the Repository Service.
