|Oracle Fusion Middleware Deployment Planning Guide for Oracle Unified Directory 11g Release 1 (11.1.1)|
To reduce the exposure of your Oracle Unified Directory proxy configuration to Single Point of Failure, you should ensure that your deployment is redundant. Typically, this can be done by installing a third party hardware load balancer, as illustrated in Figure 7-6.
Using a hardware load balancer, you can manage multiple instances of the Oracle Unified Directory proxy on separate physical machines and/or in different geographical locations.
Figure 7-6 Multiple Instances of Oracle Unified Directory proxy
When running multiple instances of the Oracle Unified Directory proxy, if you are using a distribution deployment with a global index catalog, the global index catalog should be replicated. For more information on replicating the global index catalog, see Replication of Global Index Catalogs in Oracle Fusion Middleware Administration Guide for Oracle Unified Directory.
In order to deploy the same Oracle Unified Directory proxy deployment see the instructions in Chapter 4, Setting Up the Proxy Server, in Oracle Fusion Middleware Installation Guide for Oracle Unified Directory.
