Configuring Relay Servers

Configure Relay Servers and corresponding Outbound Enablers (OEs) for an Unwired Platform system.

Prerequisites

  • All Unwired Servers and data tier servers must be installed and running.

  • The Unwired Server cluster and its nodes must be registered in Sybase Control Center.

Note: If the cluster or server name does not appear in the navigation pane, on the SCC console, you must register them with Sybase Control Center.
Task


The diagram above illustrates an Unwired Platform cluster with two Unwired Server nodes, using two Relay Servers, with Apache acting as a load balancer. This document focuses on this configuration, while providing information on what to do differently to set up different configurations, for example:
  • More than two Relay Servers
  • Hardware load balancer in place of Apache
  1. Configuring Unwired Server to use Relay Server
    Choose a method for configuring Unwired Server to use Relay Server, then generate a Relay Server configuration file. Copy the file to the Relay Server host, and quickly distribute the same configuration to multiple Relay Server nodes, with no changes.
  2. Deploying a Relay Server Configuration
    After you generate a Relay Server configuration file, you must copy it to each Relay Server host, and use it to update the Relay Server configuration. All Relay Servers working with the same Unwired Platform installation must use identical copies of the Relay Server configuration file, rs.config.
  3. Configuring the Outbound Enablers
    Set up one or more Outbound Enablers (OEs) for each Unwired Server, connecting to the load balancer, as identified in a Relay Server configuration.
  4. Configuring Apache for Relay Sever
    Modify the Apache HTTP Server configuration and environment, as needed for Relay Server.
  5. Configuring State Manager as a Service
    Set up the State Manager process to run as a service on the Relay Server host.
  6. Installing a Load Balancer
    You can use either a software or a hardware load balancer to get the best performance out of your Relay Servers.
