About Load Balancing
To set up load balancing for Info*Engine services as well as provide redundant components in case a component fails, the following processes are available:
• You can configure some components for system-wide load balancing and failures by setting up multiple instances of the components and then configuring their LDAP entries so that they have a common service name. These components can be Info*Engine task processors, adapters, or gateways. This configuration is done through the Info*Engine Property Administration utility.
• Task and JSP authors can use failure processing techniques within individual tasks or JSPs. These techniques do not require that the components have a common service name. Instead, the techniques allow authors to specify multiple components in the specific task or adapter webject being processed. Authors can also use the CONNECTION_ATTEMPTS and CONNECTION_ATTEMPTS_INTERVAL webject parameters to regulate how often a request is resent and the interval between those requests.
Your site can choose to use one or both of these methods for load balancing and failure processing.

You should not attempt to duplicate the Naming Service instance. Creating duplicate Naming Service LDAP directory entries with a common name can produce unpredictable results.
If you have a Windchill environment that has multiple method servers, do not attempt to configure the Windchill adapter manually. Windchill adapter auto-registration automatically updates the service configuration as necessary to function properly in a multiple method server environment by updating the adapter configuration to use a port range large enough to accommodate all foreground method servers.
