Sun Java System Access Manager 7.1 Administration Reference

Instance Name

The naming service reads this attribute at initialization time. This list contains the Access Manager session servers in a single Access Manager configuration. For example, if two Access Managers are installed and should work as one, they must both be included in this list. If the host specified in a request for a service URL is not in this list, the naming service will reject the request. Only the naming service protocol should be used in this attribute. See To Create a New Instance Name.
