Informatica Domain PowerCenter has a service-oriented architecture that provides the ability to scale services and share resources across multiple machines.

The Informatica domain supports the administration of the PowerCenter and Informatica services. A domain is the primary unit for management and administration of services in PowerCenter. A domain contains the following components:.

One or more nodes. A node is the logical representation of a machine in a domain. A domain may contain more than one node.

The node that hosts the domain is the master gateway for the domain. You can add other machines as nodes in the domain and configure the nodes to run application services such as the Integration Service or Repository Service. All service requests from other nodes in the domain go through the master gateway.A node runs service processes, which are the runtime representation of the application services running on a node. Service Manager. The Service Manager is built into the domain to support the domain and the application services.

The Service Manager runs on each node in the domain. The Service Manager starts and runs the application services on a machine. Application services. A group of services that represent Informatica server-based functionality. The application services that run on each node in the domain depend on the way you configure the node and the application service.You use Informatica Administrator to manage the domain. If you have the high availability option, you can scale services and eliminate single points of failure for services.

The Service Manager and application services can continue running despite temporary network or hardware failures. High availability includes resilience, failover, and recovery for services and tasks in a domain. Service Manager The Service Manager supports the domain and the application services. The Service Manager performs the following functions:. Alerts. Provides notifications about domain and service events.

Metadata Manager Service. Runs the Metadata Manager application. PowerCenter Repository The PowerCenter repository resides in a relational database. The repository stores information required to extract, transform, and load data. It also stores administrative information such as permissions and privileges for users and groups that have access to the repository.

PowerCenter applications access the PowerCenter repository through the Repository Service. You administer the repository through Informatica Administrator and command line programs.

You can develop global and local repositories to share metadata:. Global repository. The global repository is the hub of the repository domain. Use the global repository to store common objects that multiple developers can use through shortcuts.

These objects may include operational or application source definitions, reusable transformations, mapplets, and mappings. Local repositories. A local repository is any repository within the domain that is not the global repository.Use local repositories for development. From a local repository, you can create shortcuts to objects in shared folders in the global repository.

These objects include source definitions, common dimensions and lookups, and enterprise standard transformations. You can also create copies of objects in non-shared folders. You can view repository metadata in the Repository Manager. Informatica Metadata Exchange (MX) provides a set of relational views that allow easy SQL access to the PowerCenter metadata repository. You can also create a Reporting and Dashboards Service in the Administrator tool and run the PowerCenter Repository Reports to view repository metadata. Informatica Administrator Informatica Administrator is a web application that you use to administer the PowerCenter domain and PowerCenter security.

You can also administer application services for the Informatica Analyst and Informatica Developer. Application services for Informatica Analyst and Informatica Developer include the Analyst Service, the Model Repository Service, and the Data Integration Service.

Roles are collections of privileges. Privileges determine the actions that users can perform in PowerCenter applications. Assign roles and privileges to users and groups. Assign roles and privileges to users and groups for the domain and services. Manage operating system profiles. Create, edit, and delete operating system profiles.

An operating system profile is a level of security that the Integration Services uses to run workflows. The operating system profile contains the operating system user name, service process variables, and environment variables. You can configure the Integration Service to use operating system profiles to run workflows.

Domain Configuration The Service Manager maintains configuration information for an Informatica domain in relational database tables. The configuration is accessible to all gateway nodes in the domain.

The domain configuration database stores the following types of information about the domain:. Domain configuration. Domain metadata such as the host names and the port numbers of nodes in the domain. The domain configuration database also stores information on the master gateway node and all other nodes in the domain. Includes CPU usage for each application service and the number of Repository Services running in the domain. Users and groups. Information on the native and LDAP users and the relationships between users and groups.

Privileges and roles. Information on the privileges and roles assigned to users and groups in the domain.

Each time you make a change to the domain, the Service Manager updates the domain configuration database. For example, when you add a node to the domain, the Service Manager adds the node information to the domain configuration. All gateway nodes connect to the domain configuration database to retrieve the domain information and to update the domain configuration.
