Load Balancers Network Prerequisites
2.2 Network Prerequisites
This section describes the network prerequisites for the enterprise deployment topologies: ■ Load balancers ■ Configuring virtual server names and ports on the load balancer ■ WebLogic Administration Server Virtual IP Addresses ■ Managing Oracle Fusion Middleware component connections ■ Oracle Access Manager communication protocols and terminology ■ Firewall and port configuration This section contains the following topics: ■ Section 2.2.1, Load Balancers ■ Section 2.2.2, Configuring Virtual Server Names and Ports on the Load Balancer ■ Section 2.2.3, Virtual IP Addresses ■ Section 2.2.4, Managing Oracle Fusion Middleware Component Connections ■ Section 2.2.5, Oracle Access Manager Communication Protocol and Terminology ■ Section 2.2.6, Firewall and Port Configuration2.2.1 Load Balancers
The enterprise topologies use an external load balancer. This external load balancer must have the following features: ■ Ability to load-balance traffic to a pool of real servers through a virtual host name: Clients access services using the virtual host name instead of using actual host names. The load balancer can then load balance requests to the servers in the pool. ■ Port translation configuration. ■ Monitoring of ports HTTP and HTTPS. ■ Virtual servers and port configuration: Ability to configure virtual server names and ports on your external load balancer, and the virtual server names and ports must meet the following requirements: Note: Oracle recommends configuring all nodes in the topology identically with respect to operating system levels, patch levels, user accounts, and user groups. Prerequisites for Enterprise Deployments 2-3 – The load balancer should allow configuration of multiple virtual servers. For each virtual server, the load balancer should allow configuration of traffic management on more than one port. For example, for OracleAS Clusters, the load balancer must be configured with a virtual server and ports for HTTP and HTTPS traffic. – The virtual server names must be associated with IP addresses and be part of your DNS. Clients must be able to access the external load balancer through the virtual server names. ■ Ability to detect node failures and immediately stop routing traffic to the failed node. ■ Resource monitoring port monitoring process failure detection: The load balancer must be able to detect service and node failures through notification or some other means and to stop directing non-Oracle Net traffic to the failed node. If your external load balancer has the ability to automatically detect failures, you should use it. ■ Fault tolerant mode: It is highly recommended that you configure the load balancer to be in fault-tolerant mode. ■ Other: It is highly recommended that you configure the load balancer virtual server to return immediately to the calling client when the back-end services to which it forwards traffic are unavailable. This is preferred over the client disconnecting on its own after a timeout based on the TCPIP settings on the client machine. ■ Sticky routing capability: Ability to maintain sticky connections to components based on cookies or URL. ■ SSL acceleration this feature is recommended, but not required. ■ Configure the virtual servers in the load balancer for the directory tier with a high value for the connection timeout for TCP connections. This value should be more than the maximum expected time over which no traffic is expected between the Oracle Access Manager and the directory tier. ■ Ability to Preserve the Client IP Addresses: The Load Balancer must have the capability to insert the original client IP address of a request in an X-Forwarded-For HTTP header to preserve the Client IP Address.2.2.2 Configuring Virtual Server Names and Ports on the Load Balancer
