PowerCenter Mappings and Workflows Overview
PowerCenter is a processing engine that Data Integration Hub uses to run Data Integration Hub publications and subscriptions from and to on-premises applications, to run publication pre-processes and subscription post-processes, and to perform actions for monitoring rules that invoke workflows.
For automatic mapping publications and subscriptions, Data Integration Hub creates the PowerCenter mappings that process the publications and subscriptions based on the data structure that you define in the topic. For custom mapping publications and subscriptions, you use the PowerCenter Client tools to develop the PowerCenter mappings and workflows that process the publications and subscriptions. You also develop PowerCenter mappings and workflows for publication pre-processing, subscription post-processing, and monitoring rules that invoke PowerCenter workflows.
After you develop the workflow in PowerCenter, you use the
Data Integration Hub Operation Console to import the PowerCenter workflow into a
Data Integration Hub workflow.
For details, see Creating a Data Integration Hub Workflow.The Data Integration Hub operator then creates a publication, a subscription, or a monitoring rule in the Data Integration Hub Operation Console, and selects the Data Integration Hub workflow or workflows which are based on the PowerCenter workflow. For more information, see the Data Integration Hub Operator Guide.
You can find sample workflows in the following directory: <DIHInstallationDir>/samples. Each sample workflow has an associated readme file that describes the sample workflow and contains instructions.
