摘要：
A method for upgrading one of several computer programs stored on an application server in a distributed computing environment while permitting the application server to continue to service requests for other computer programs. In accordance with the method, the application server is prevented from receiving any new requests for the computer program. The system then waits until all current requests serviced by the application server for that computer program have ended. Then, after acknowledging completion of upgrading of the computer program, the application server is permitted to receive any new requests for the computer program. Apparatuses for carrying out the inventive method are provided.
