CONFIGURING
The OpenSocial component is deployed and configured on two server components: a Domino mail server, and another Domino server running Shindig, both with the OpenSocial component installed. In addition, the Domino mail server hosts the widgets catalog, and the Domino server running Shindig hosts the credential store application. You can deploy these two components either on a single Domino server or on two separate Domino servers; but, clustering is not supported.
