Adding or Removing a Relay Server with Sybase Control Center

Scale an existing relay server cluster by adding more relay server nodes to the existing production architecture.

1. In the Sybase Control Center navigation pane, click the cluster name for which relay servers are required, then click the Relay Server tab.
2. If you need to add a new relay server:
   1. Click New.
   2. Configure all pages of the wizard then click Finish. The relay server is registered and these properties are stored in the cluster database. See Creating a Custom Relay Server Configuration in the Sybase Control Center online help.
3. If you need to remove a relay server, select the relay server name and click Delete.
   Deleting a relay server only removes it from Sybase Control Center and unregisters it from the cluster database.
4. To update existing configuration files to hold new relay server node definitions:
   1. Export the properties by selecting the new relay server node entry in the Relay Server tab, then clicking Generate.
   2. When prompted, generate the whole file.
      The farm information is updated when you apply the changes in the last step.
   3. On each relay server node, copy and paste these lines from the generated file into the configuration file.
      The path depends on the host type:

      • For IIS: C:\Inetpub\wwwroot\IAS_relay_server\Server\rs.config
      • For Apache: <Apache_Home>/modules/rs.config
5. To remove properties of deleted relay servers, manually delete the definition from the configuration file.
6. Save all edits.
7. To upload these configuration changes to the relay server run:

   rshost –u –f <WebServerPath>rs.config
