Abstract

See full text

A system and method for facilitating compatibility with a prior process used for connecting a user terminal to a selected server in a system having a plurality of servers. The prior process has the server perform a task on behalf of the terminal. The system includes a server determination process for retrieving from storage a table of data identifying the servers, and for determining an address currently associated with each server. Then, a chooser process enables the user to select from the table, one of said servers for connection to the terminal with a connection process, responsive to a signal from the terminal, that initiates a connection of the terminal to the selected server. The plurality of servers in the system includes at least one parallel server comprised of multiple processors. The data in the table identifying the parallel server is a generic identifier, and a process is employed, which preferably uses predetermined dynamic criteria, to periodically associate a specific processor of the parallel server with that generic name. To enable the load to be balanced across the plural processors of the parallel server, the server determination process is adapted to recognize any generic identifier in the table, and to determine the address associated with that generic identifier after a user selection of the parallel server corresponding to that generic identifier has been made.
