Virtual IP Addresses Managing Oracle Fusion Middleware Component Connections

2-6 Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity Management In addition, ensure that the virtual server names are associated with IP addresses and are part of your DNS. The computers on which Oracle Fusion Middleware is running must be able to resolve these virtual server names.

2.2.3 Virtual IP Addresses

A virtual IP address is an unused IP Address which belongs to the same subnet as the hosts primary IP address. It is assigned to a host manually and Oracle WebLogic Managed servers are configured to listen on this IP Address. In the event of the failure of the node where the IP address is assigned, the IP address is assigned to another node in the same subnet, so that the new node can take responsibility for running the managed servers assigned to it. The following is a list of the Virtual IP addresses required by Oracle Identity Management: adminvhn.mycompany.com In Enterprise deployments the WebLogic Administration Server must be able to continue processing requests after the host it is residing on fails. A virtual IP address should be provisioned in the application tier so that it can be bound to a network interface on any host in the application tier. The WebLogic Administration Server is configured later to listen on this virtual IP address, as discussed later in this manual. The virtual IP address fails over along with the Administration Server from IDMHOST1 to IDMSHOST2, or vice versa. soavhnx One virtual IP address is required for each SOA managed server. This enables the servers to participate in Server migration. Provision a virtual IP address in the application tier so that it can be bound to a network interface on any host in the application tier. oimvhnx One virtual IP Address is required for each Oracle Identity Manager managed server.

2.2.4 Managing Oracle Fusion Middleware Component Connections

To ensure consistent availability of all services, ensure that the connection timeout values for all Oracle Fusion Middleware components are set to a lower timeout value than that on the firewall and load balancing router. If the firewall or load balancing router drops a connection without sending a TCP close notification message, then Oracle Fusion Middleware components continue to try to use the connection when it is no longer available.
