Abstract: An approach is provided for controlling a rate at which requests from a client computer will be received by a server application executed on a server computer. Requests are received by the server computer at different times from the client computer and time intervals between different pairs of successive requests are measured. The server computer determines that each time interval is within a predefined range of time intervals. Based on each time interval being within the predefined range, the server computer determines and blocks a denial of service attack or an overload of requests from the client computer.

Requests are received by the server computer at different times from the client computer and time intervals between different pairs of successive requests are measured. Based on the time intervals, (1) a historical rate of requests from the client computer is determined and a limit on a rate for the server application to receive subsequent requests from the client computer is determined and enforced based on the historical rate of requests, or (2) a range of the time intervals is determined to be within a predefined range of time intervals and based on the range being within the predefined range, a denial of service attack or an overload of requests from the client computer is determined and blocked.

Abstract: A method and system for processing a request by a user of a program in a first computer. The program in the first computer displays, in the first computer, a first computer screen and another computer screen superimposed on the first computer screen. The program in the first computer receives a request and updates a first working storage area to indicate the request. The first computer sends to a second computer a copy of contents of a first working storage area in the first computer. The first computer receives from the second computer contents of a second working storage area in the second computer updated with a result of a copy of a program in the second computer processing the request, and in response, the first computer updates the contents of the first working storage area with the contents of the updated second working storage.

Abstract: A computer system and computer program product implementing a method in a Customer Information Control System (CICS) Application configured to process information residing on remote systems and display such information on a local system, using a same program residing on both the remote system(s) and the local system. The method includes, for example, sending programming functions of a local system with a request for information to a remote system. The method further includes processing the programming functions of the local system with the request for information on the remote system to obtain updated information from the remote system. The updated information is sent to the local system for display.

Abstract: A method and system for controlling access to an application being executed by a server. A time interval between the server's receipt times of a first request and a second request. The first and second requests are included in multiple requests for an access to the application. An adjustment value is selected based on the time interval and multiple historical time intervals. Each historical time interval is between the server's receipt times of two requests of the multiple requests. The two requests' receipt times are prior to the first and second requests' receipt times. An accumulator is adjusted with the adjustment value, resulting in the accumulator's value exceeding a predefined threshold. Access to the application is controlled via a warning, a delay in responding to the second request, a temporary halt in processing, or a permanent access denial in response to the accumulator's value exceeding the threshold.
