Abstract: A method for controlling feature upgrades on a plurality of payment system devices, onsite, in a distributed network, involves a web service at each of the plurality of payment system devices. An upgrade utility program communicates with the web service at each of the plurality of payment system devices, and presents a list of available payment system devices to the user. The list of available payment system devices identifies each device by location. A group of payment system devices is selected for receiving feature upgrades, and for each payment system device in the selected group, at least one feature upgrade is selected. A request file is created that contains information indicative of the payment system devices selected for receiving feature upgrades and indicative of the at least one feature upgrade for each selected payment system device.

Abstract: A method, apparatus, and article of manufacture web services provides web services with load balancing of image processing in a document processing environment. A Load Balancing Web Service hosted on a network connected server receives web services processing requests from application programs using a web services interface. The load balancing web service forwards these processing requests to data processing web services running on a plurality of web servers using a priority scheme that attempts to assign requests based upon differences in the processing time needed by these servers to process pending requests, and based on round robin cycling when there are no differences in the processing time needed by these servers to process requests. The load balancing web service receives responses from the data processing web services running on a plurality of web servers and forwards the responses to the application programs.
