Sample Project Configuration File

Use these project configuration CCR file examples to build and modify your XML-based project configuration file.

You can build and modify the project configuration CCR file using the Studio Project Configuration editor or a text editor.

In this example, notice that the CCR file is organized in sections according to the preferences being set, including clusters, managers, bindings, parameters, adapters, and project settings. For information on bindings and parameters, see the SAP Event Stream Processor: Developer Guide. For information on adapters and adapter property sets, see the SAP Event Stream Processor: Adapters Guide.

This example shows the Deployment section of the CCR file for a deployment with failover enabled and affinities configured on both instances of an active-active (HA) project.
