12.3 Oracle Fusion Middleware Cold Failover Cluster Example Topologies

This section illustrates sample Cold Failover Cluster topologies. Since there are many possible combinations of topologies, these topologies are illustrative only. To achieve these topologies, more than one of the transformation steps apply. Refer to the steps mentioned earlier to configure the transformation.

12.3.1 Example Topology 1

Figure 12–3 shows an Oracle WebCenter Cold Failover Cluster deployment. Both the Administration Server and the WebCenter Managed Servers are in the domain, and failover as unit. Therefore, they share the same virtual IP and are installed together on the same shared disk. There may be an Oracle HTTP Server front ending this topology. It is on a separate node in the example topology. It can also be on the same node, and can be part of the Cold Failover Cluster deployment. In this example, the database is also on a separate node. However, it is equally likely that the database is on the same cluster and is also Cold Failover Cluster-based using its own virtual IP and shared disk. Note: oracle_sid should be in upper case. Note: oracle_sid should be in upper case. 12-52 Oracle Fusion Middleware High Availability Guide Figure 12–3 Cold Failover Cluster Example Topology 1

12.3.2 Example Topology 2

Figure 12–4 shows an example SOA Cold Failover Cluster deployment. In this example, only the SOA instance is deployed as Cold Failover Cluster, and the Administration Server is on a separate node. The database is also on a separate node in this example topology. Oracle HTTP Server in this case is part of the Cold Failover Cluster deployment, and part of the same failover unit as the SOA Managed Servers. Important variants of this topology include a Cold Failover Cluster Administration Server on the same hardware cluster. It may share the same virtual IP and shared disk as the SOA Managed Servers SOA and Administration Server are part of the same failover unit or use a separate virtual IP, and shared disk Administration Server fails over independently. Similarly, depending on the machine capacity, the database instance can also reside on the same hardware cluster.
