Repository Service: It manages the metadata in the repository database and repository connection requests from client applications. It also monitors the status of Repository Agents. The Repository Agent is a separate multi-threaded process that recovers, inserts, and updates metadata in the repository database tables.
Web Services Hub: It is a gateway to showcase the PowerCenter functionality for external clients.
SAP BW Services: It looks out for RFC requests from SAP BW and commences workflows to extract data from, or load data into SAP BW.
Repository Manager is used for administering repositories and performing folder functions like creating, edit, and deleting folders. It also manages users and groups. You can also assign and invoke repository privileges and folder permissions, view lock, and unlock objects.
The repository manager consists of the following:
A designer is used to import or create a target definition. Informatica designer is the client where we decide how to move data between various sources and targets. It is used for creating source definitions, transformations, target definitions, and further to develop mappings.
It is used to create a workflow (set of instructions) to execute mappings. The workflow includes sessions and other tasks that are used for accomplishing the overall operational purpose. Workflows are built and run through workflow manager in the PowerCenter application. Workflow designer maps the execution order and dependencies of Worklets, sessions, and tasks for the Informatica server.
It monitors workflows and tasks. Details of workflow or task can be viewed in either Task view or Gantt view. We can run, abort, stop, and resume workflows. The workflow monitor showcases workflows that runs at least once. It continuously receives information from the repository service and integration services. It also fetches information to display historic information from the repository.
Informatica Administration Console is the administration tool used for both the Informatica security and the Informatica domain.
