Can Discoverer 10g be implemented with third-party load-balancers?
Yes, customers have successfully configured Discoverer 10g with hardware-based load-balancers. Note that Oracle does not explicitly certify Discoverer 10g with third-party load-balancers, and Oracle Support can provide only best-efforts support for this configuration. Customers with issues that cannot be reproduced in Release 12 environments without the third-party load-balancer are advised to contact the third-party vendor for advanced product-specific assistance. System administrators interested in experimenting with this configuration are advised to configure the load-balancer to handle routing requests for Discoverer services “with affinity” (i.e. “persistent” connections) so that traffic from a given client is routed to the same application-tier server node for Discoverer. This ensures that the existing Discoverer session is reused, rather than being recreated from scratch on another server, a process which may incur additional processing overhead.
