Method and system for managing server load to execute transactions of an application program on multiple servers

Abstract

A method and system for managing server load to execute groups of transactions of an application program on N servers. A condition, ascertained for each transaction group, is that a current value of global multiplicity is not or is, respectively, less than a specified maximum value of global multiplicity. For each transaction group, an instruction is or is not issued to each server to change a current value of the maximum permitted local multiplicity for each server to a new value of the maximum permitted local multiplicity. For each transaction group: global multiplicity denotes a number of transactions concurrently performed by the N servers collectively; and local multiplicity for each server denotes a number of transactions concurrently performed by each server. The issuing or not issuing depends on the ascertained condition and whether the current value of the maximum local multiplicity is a default value for each server.
