Configuring a Load Balancing Scenario

Top  Previous  Next


In order to configure a load balancing scenario, you need at least one Gateway installation and two Server installations.



Configuring the Gateway


Under this role, z/Scope Anywhere Gateway responds to all web-page requests and, when a connection is solicited, it selects the appropriate Server to forward that request to.


To  configure the Gateway, open the Gateway Manager. Set the IP and port where the Gateway will run. If you only have one gateway, this is where the users will connect to. If you use more than one Gateway in your architecture, you will use this IP in the DNS server you set up to distribute the connection between the Gateways.

Also, set the Network ID. All the Gateway and Server installations involved in a Load Balancing architecture share the same network ID.





Configuring the Server


Under this role, z/Scope Anywhere only processes forwarded connections. The Server is responsible for establishing and processing the connections assigned by the Gateway.

To  configure the Server, open z/Scope Anywhere Configuration Manager and go the 'Communication' tab.



Press the 'Add' button to add a gateway to the Gateway List. This means that now this server's resources can be accessed through the listed gateways.

Make sure that the Network ID is the same for all the gateways and servers involved in this load balancing architecture.


Then, go to the 'Config Setup' tab in the 'Environment' settings:



Set the 'Configuration Path' field in a network location that you can access from the other Server installations.

Once you share the configuration path, all the settings will be shared with other z/Scope Anywhere installations. Make sure you modify the settings from one location at a time, as all changes will be reflected in the other installations.


Also, make sure all the Gateways' IPs are public to the locations that will access z/Scope Anywhere through a web browser.
