Highly Available and Scalable Oracle RAC Networking with Oracle Solaris 10 IPMP

Overview Businesses world wide rely on network connectivity in order to service clients, disruption in network services can lead to loss of revenue, and loss of productivity. Business continuity and minimizing planned downtime involves ensuring that the application and systems are designed for resilient to failures. Highly available networking infrastructure could be leveraged by configuring multiple physical paths to the network to eliminate single points of failure. Oracle Solaris supports high availability at the network layer out of the box. Oracle Solaris network high availability options include IP multipathing (IPMP) and Link level aggregation. Oracle RAC configuration has specific networking requirement, choices for IPMP configuration will be discussed for addressing those requirement, and where Oracle RAC with Clusteware can take benefits of them in seamless fashion. This paper contributes to the existing Oracle RAC and IPMP knowledge base by bringing out the best practices for configuring a fault resilient IPMP network for Oracle RAC with Oracle Clusterware.
