Client/server architecture supporting concurrent servers
Abstract
A transaction manager intercepts all requests for service from any of a plurality of clients, establishes connections independently of task requests and assigns available servers to the requests in the order the requests are received in order to provide equitable distribution of service resources over an increased number of client/server connections. Preferably, the transaction manager provides for starting at least one server independently of any request, direction of all client requests for server connections to a transaction manager independently of any server, placement of task requests in a queue and starting and stopping additional servers based on queue length.
