Installing a Load Balancer

(Applies only to deployments with two or more Relay Servers.) You can use either a software or a hardware load balancer to get the best performance out of your Relay Servers.

You should be able to use any hardware or software load balancer with the Relay Servers you have installed to support your SAP Mobile Platform cluster. This document describes how to use Apache 2.2, with proxy load balancing.

If you are using a hardware load balancer, see the product documentation for instructions on setting it up.

If you are using a software load balancer other than Apache 2.2, see the program documentation for instructions on setting it up.

Using Relay Server with a Third-Party Load Balancer
You can use Relay Server with hardware or software load balancers to create Relay Server farms. However, sessions must be persisted.
Configuring Apache 2.2 as a Load Balancer
To use Apache 2.2 and later as a software load balancer, edit the Apache configuration file to enable mod_proxy and mod_proxy_balancer and set up the load-balancing features.
Configuring Apache as a Load Balancer for the EIS Back End
When you use Apache as a load balancer for the EIS back end, some of the configuration file settings are different from those for Apache as a load balancer on the front end.
