Informatica Complete Reference Introduction PowerCenter provides an environment that allows you to load data into a centralized location, such as a data warehouse or operational data store ODS. You can extract data from multiple sources, transform the data according to business logic you build in the client application, and load the transformed data into file and relational targets. PowerCenter also provides the ability to view and analyze business information and browse and analyze metadata from disparate metadata repositories. The Informatica domain is the primary unit for management and administration within PowerCenter. The Service Manager runs on an Informatica domain. The Service Manager supports the domain and the application services.

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. Provides notifications about domain and service events. Authorizes user requests for domain objects.

Requests can come from the Administrator tool or from infacmd. Manages domain configuration metadata. Manages node configuration metadata. Registers license information and verifies license information when you run application services. Provides accumulated log events from each service in the domain. You can view logs in the Administrator tool and the Workflow Monitor. Manages users, groups, roles, and privileges.

Manages the connections to Informatica Analyst. Performs data integration tasks for Informatica Analyst, Informatica Developer, and external clients. Manages connections to the PowerCenter repository. Runs PowerCenter sessions and workflows. Exposes PowerCenter functionality to external clients through web services. Runs the Data Analyzer application.

Runs the JasperReports application. Runs the Metadata Manager application. 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. You administer the repository through Informatica Administrator and command line programs.

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. 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. 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.

Domain objects include services, nodes, and licenses. Manage all application services in the domain, such as the Integration Service and Repository Service.

Configure node properties, such as the backup directory and resources. You can also shut down and restart nodes. Create and manage objects such as services, nodes, licenses, and folders. Folders allow you to organize domain objects and manage security by setting permissions for domain objects. View and edit properties for all objects in the domain, including the domain object. You can generate and upload node diagnostics to the Configuration Support Manager.

In the Configuration Support Manager, you can diagnose issues in your Informatica environment and maintain details of your configuration.

Other domain management tasks include applying licenses and managing grids and resources. Create, edit, and delete native users and groups.

Configure a connection to an LDAP directory service. Import users and groups from the LDAP directory service.

Create, edit, and delete roles. Roles are collections of privileges. Privileges determine the actions that users can perform in PowerCenter applications. Assign roles and privileges to users and groups for the domain and services. 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. 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. Information on the native and LDAP users and the relationships between users and groups. 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. PowerCenter Client The PowerCenter Client application consists of the tools to manage the repository and to design mappings, mapplets, and sessions to load the data.

Informatica PowerCenter - Documentation

Use the Designer to create mappings that contain transformation instructions for the Integration Service. Use the Mapping Architect for Visio to create mapping templates that generate multiple mappings. Use the Repository Manager to assign permissions to users and groups and manage folders. Use the Workflow Manager to create, schedule, and run workflows. A workflow is a set of instructions that describes how and when to run tasks related to extracting, transforming, and loading data.

Use the Workflow Monitor to monitor scheduled and running workflows for each Integration Service. For more information about using iReports Designer, see the Jaspersoft documentation.

Install the client application on a Microsoft Windows computer.

Import or create source definitions. Import or create target definitions. Develop transformations to use in mappings. You can also develop user- defined functions to use in expressions. Create sets of transformations to use in mappings. Create mappings that the Integration Service uses to extract, transform, and load data. Connect to repositories and open folders within the Navigator.

You can also copy objects and create shortcuts within the Navigator. Open different tools in this window to create and edit repository objects, such as sources, targets, mapplets, transformations, and mappings. View details about tasks you perform, such as saving your work or validating a mapping. Displays shapes that represent PowerCenter mapping objects. Drag a shape from the Informatica stencil to the drawing window to add a mapping object to a mapping template.

Displays buttons for tasks you can perform on a mapping template. Contains the online help button. Work area for the mapping template. Drag shapes from the Informatica stencil to the drawing window and set up links between the shapes. Set the properties for the mapping objects and the rules for data movement and transformation.

Assign and revoke folder and global object permissions. Create, edit, copy, and delete folders. Work you perform in the Designer and Workflow Manager is stored in folders. If you want to share metadata, you can configure a folder to be shared. Analyze sources, targets, mappings, and shortcut dependencies, search by keyword, and view the properties of repository objects. Displays all objects that you create in the Repository Manager, the Designer, and the Workflow Manager.

It is organized first by repository and by folder. Provides properties of the object selected in the Navigator. The columns in this window change depending on the object selected in the Navigator.

Provides the output of tasks executed within the Repository Manager. The following figure shows the Repository Manager interface: Repository Objects You create repository objects using the Designer and Workflow Manager client tools.

Definitions of database objects such as tables, views, synonyms, or files that provide source data. Definitions of database objects or files that contain the target data. A set of source and target definitions along with transformations containing business logic that you build into the transformation. These are the instructions that the Integration Service uses to transform and move data. Transformations that you use in multiple mappings.

A set of transformations that you use in multiple mappings. Sessions and workflows store information about how and when the Integration Service moves data.

You can nest worklets inside a workflow. Create a workflow by connecting tasks with links in the Workflow Designer. You can also create tasks in the Workflow Designer as you develop the workflow. Informatica makes use of service driven architecture that has the ability to share services and resources among several machines.

S Air Force are some of the major clients who use Informatica Powercenter as a tool for data integration. Informatica was created by Informatica Corp. The main components of Informatica are its server, repository server, client tools and repository. The PowerCenter server completes projects based on flow of work developed by work flow managers. One can monitor the work flows with the use of a work flow monitor.

With the aid of mapping designer, tasks can be structured to create mapping between source and target. Mapping is defined as a pictorial representation of data flow to target from source. Transformations such as filtering, aggregation, and joining are the main examples of transformation. Informatica presents you with a rich set of features such as operations at row level on data, integration of data from semi-structured, multiple structured, or unstructured systems, data operation scheduling.
