When you initially start the Web Services Hub after installation, no real-time web services are available. You create real-time web services when you expose PowerCenter workflows as web services. You can create clients to run a web service workflow and get the results of the workflow process. The web service takes a SOAP message request and produces a SOAP message response.

You can create a service mapping to receive a message from a web service client, transform it, and write it to any target that PowerCenter supports. You can also create a web service mapping with both a web service source and target definition to receive a message request from a web service client, transform the data, and send the response back to the web service client. The source and target definitions represent service operations. The source defines the user request and the target defines the response.

After you create a mapping, you can create a web service workflow to run the process defined in the web service mapping. A web service workflow is a workflow enabled as a web service. Configure the web service workflow, and add sessions to the workflow. When you save the workflow, the Web Services Hub publishes the web service on the Web Services Hub Console. The Integration Service can perform parallel processing of both

request-response

and one-way services.
