Redundant Device Integration (RDI) objects are the standard method of implementing I/O failover in Application Server. This article shows you how to configure a basic setup.
- Before configuring an RDI Object, you must have two DDESuiteLink Client Objects configured (one for the primary one for the backup). These will be referenced in the RDI object that you are setting up. In the DDESuiteLinkClient object, you define the server node, server name (application name) and topic (device groups). These, along with the items, must match on both client objects.
- The RDI object is a separate object from the DDESuiteLink client. You deploy this under an application engine on a desired platform in the galaxy. The first thing to reference is the primary and backup data sources (these will be your primary and backup DDESuiteLinkClients).
- The final step prior to deployment is defining any topics/device groups for the RDI object. The topics on both DDESuiteLink clients and the RDI object should match.
NOTE: For standard I/O referencing in Application Server object attributes, reference the RDI Object and desired scan group instead of the DDESuitelink client and it's corresponding topic.
