Information in this document applies to any platform.
The purpose of this document is to demonstrate how to integrate a 10g (or 11.1) database with 11gR2 Grid Infrastructure.
With 11gR2 Grid, client connections are supposed to use the Single Client Access Name (SCAN) to connect to instances in a RAC cluster.
While 10g/11gR1 sqlnet does not support certain aspects of this new feature, it is still possible to configure 10g/11gR1 clients and database instances to integrate with the 11gR2 Grid infrastructure using the SCAN. This document provides an example on how to implement this.
The solution outlined in this document requires that the SCAN VIPs are fixed, hence it cannot be used if the SCAN VIPs are dynamically allocated via GNS (using DHCP).
