System, method and program for coordinating timeouts for distributed servers

A computer program product for determining time-outs for sessions between first and second servers and between first and third servers, said program product comprising:

• a computer readable storage medium;
• first program instructions, for execution within said first server, to receive a client request for a first service, said first service requiring a second service from said second server and a third service from said third server;
• and
• second program instructions, for execution within said first server, to determine a first timeout for a first session between said first server and said second server to obtain said second service, and determine a second timeout for a second session between said first server and said third server to obtain said third service, said first and second time-outs being based in part on an order in which said second and third servers begin their respective services;
• and
• wherein said first and second program instructions are recorded on said medium.

A method for applying session time-outs, said method comprising the steps of:

• a first server receiving a client request for a first service;
• said first server establishing a first session with said client, said first service requiring a second service from a second server in a second session and a third service from a third server in a third session;
• said first server specifying a first timeout for said first session;
• said first server determining a second timeout, based in part on said first timeout, for said second session;
• and
• said first server determining a third timeout, based in part on said first timeout, for said third session;
• and
• wherein a duration of said second timeout is different than a duration of said third timeout.

A computer system for determining session time-outs, said system comprising:

• a CPU, a computer readable storage media, and a computer readable memory;
• first program instructions to receive a client request for a first service;
• second program instructions to establish a first session with said client, said first service requiring a second service from a second server in a second session and a third service from a third server in a third session;
• third program instructions to specify a first timeout for said first session;
• fourth program instructions to determine a second timeout, based in part on said first timeout, for said second session;
• and
• fifth program instructions to determine a third timeout, based in part on said first timeout, for said third session;
• and
• wherein a duration of said second timeout is different than a duration of said third timeout and wherein said first, second, third, fourth, and fifth program instructions are stored on said computer readable media for execution by said CPU via said computer readable memory.

A method for determining time-outs for sessions between first and second servers and between first and third servers, said method comprising the steps of:

• said first server receiving a client request for a first service, said first service requiring a second service from said second server and a third service from said third server;
• and
• said first server determining a first timeout for a first session between said first server and said second server to obtain said second service, and said first server determining a second timeout for a second session between said first server and said third server to obtain said third service;
• and wherein
• said second server begins said second service before said third server begins said third service, said first timeout is based on a time required for said second server to provide said second service and said third server to provide said third service, and said second timeout is based on a time required for said third server to provide said third service, a duration of said second timeout being shorter than a duration of said first timeout.
