Informatica PowerCenter 8x Key Concepts – 4

owerCenter Client (contd)

Workflow Manager : In the Workflow Manager, we define a set of instructions called a workflow to execute mappings we build in the Designer. Generally, a workflow contains a session and any other task we may want to perform when we run a session. Tasks can include a session, email notification, or scheduling information.

A set of tasks grouped together becomes worklet. After we create a workflow, we run the workflow in the Workflow Manager and monitor it in the Workflow Monitor. Workflow Manager has following three window panes,Task Developer, Create tasks we want to accomplish in the workflow. Worklet Designer, Create a worklet in the Worklet Designer. A worklet is an object that groups a set of tasks. A worklet is similar to a workflow, but without scheduling information. You can nest worklets inside a workflow. Workflow Designer, Create a workflow by connecting tasks with links in the Workflow Designer. We can also create tasks in the Workflow Designer as you develop the workflow. The ODBC connection details are defined in Workflow Manager “Connections “ Menu .

Workflow Monitor : We can monitor workflows and tasks in the Workflow Monitor. We can view details about a workflow or task in Gantt Chart view or Task view. We can run, stop, abort, and resume workflows from the Workflow Monitor. We can view sessions and workflow log events in the Workflow Monitor Log Viewer.

The Workflow Monitor displays workflows that have run at least once. The Workflow Monitor continuously receives information from the Integration Service and Repository Service. It also fetches information from the repository to display historic information.

The Workflow Monitor consists of the following windows:

Navigator window – Displays monitored repositories, servers, and repositories objects.

Output window – Displays messages from the Integration Service and Repository Service.

Time window – Displays progress of workflow runs.

Gantt chart view – Displays details about workflow runs in chronological format.

Task view – Displays details about workflow runs in a report format.

Repository Manager

We can navigate through multiple folders and repositories and perform basic repository tasks with the Repository Manager. We use the Repository Manager to complete the following tasks:

1. Add domain connection information, we can configure domain connection information.

2. Add and connect to a repository, we can add repositories to the Navigator window and client registry and then connect to the repositories.

3. Work with PowerCenter domain and repository connections, we can edit or remove domain connection information. We can connect to one repository or multiple repositories. We can export repository connection information from the client registry to a file. We can import the file on a different machine and add the repository connection information to the client registry.

4. Change your password. We can change the password for our user account.

5. Search for repository objects or keywords. We can search for repository objects containing specified text. If we add keywords to target definitions, use a keyword to search for a target definition.

6. View objects dependencies. Before we remove or change an object, we can view dependencies to see the impact on other objects.

7. Compare repository objects. In the Repository Manager, wecan compare two repository objects of the same type to identify differences between the objects.

8. Truncate session and workflow log entries. we can truncate the list of session and workflow logs that the Integration Service writes to the repository. we can truncate all logs, or truncate all logs older than a specified date.
