Informatica Domain Overview

Informatica has a service-oriented architecture that provides the ability to scale services and to share resources across multiple machines. The Informatica domain is the primary unit for the management and administration of services.

You can log in to Informatica Administrator after you install Informatica. You use the Administrator tool to manage the domain and configure the required application services before you can access the remaining application clients.

The Informatica domain contains the following components:

Application clients. A group of clients that you use to access underlying Informatica functionality. Application clients make requests to the Service Manager or application services.

Application services. A group of services that represent server-based functionality.

An Informatica domain can contain a subset of application services.

You create and configure the application services that the application clients require.

Application services include system services that can have a single instance in the domain. When you create the domain, the system services are created for you. You can configure and enable a system service to use the functionality that the service provides.

Profile warehouse. A relational database that the Data Integration Service uses to store profile results.

Reference data warehouse. A relational database that stores reference data values for the reference table objects in the Model repository.

Repositories. A group of relational databases that store metadata about objects and processes required to handle user requests from application clients.

Service Manager. A service that is built in to the domain to manage all domain operations. The Service Manager runs the application services and performs domain functions including authentication, authorization, and logging.

Workflow database. A relational database that stores run-time metadata for workflows.

The following table lists the application clients, not including the Administrator tool, and the application services and the repositories that the client requires:

Application Client	Application Services	Repositories
Informatica Analyst	Analyst Service Content Management Service Data Integration Service Model Repository Service Search Service	Model repository
Informatica Developer	Analyst Service Content Management Service Data Integration Service Model Repository Service	Model repository
Metadata Manager	Metadata Manager Service PowerCenter Integration Service PowerCenter Repository Service	Metadata Manager repository PowerCenter repository
PowerCenter® Client	PowerCenter Integration Service PowerCenter Repository Service	PowerCenter repository
Web Services Hub Console	PowerCenter Integration Service PowerCenter Repository Service Web Services Hub	PowerCenter repository

The following application services are not accessed by an Informatica application client:

PowerExchange® Listener Service. Manages the PowerExchange Listener for bulk data movement and change data capture. The PowerCenter Integration Service connects to the PowerExchange Listener through the Listener Service.

PowerExchange Logger Service. Manages the PowerExchange Logger for Linux, UNIX, and Windows to capture change data and write it to the PowerExchange Logger Log files. Change data can originate from DB2 recovery logs, Oracle redo logs, a Microsoft SQL Server distribution database, or data sources on an i5/OS or z/OS system.

SAP BW Service. Listens for RFC requests from SAP BI and requests that the PowerCenter Integration Service run workflows to extract from or load to SAP BI.
