First Claim
1. A method for allocating a computer resource from a server pool to computer systems which includes a first computer system, a second computer system, and a managing computer, the method comprising:
- storing, by the managing computer, a first software list indicating a first plurality of software programs required by the first computer system, and a second software list indicating a second plurality of software programs required by the second computer system, where the first plurality of software programs are stored on a disk image of the first computer system and the second plurality of software programs are stored on a disk image of the second computer system;
in the server pool, and based on the first software list and the second software list, creating, by the managing computer;
a first group for managing the first plurality of software programs installed on a first computer,a second group for managing the second plurality of software programs installed on a second computer, anda third group for managing a software program installed on a third computer, wherein the software program is common to both the first plurality of software programs and the second plurality of software programs;
for the first computer system, searching, by the managing computer, the first computer from the first group;
searching, by the managing computer, the third computer from the third group; and
allocating, by the managing computer, the searched first computer to the first computer system;
for the second computer system, searching, by the managing computer, the second computer from the second group;
searching, by the managing computer, the third computer from the third group; and
allocating, by the managing computer, the searched second computer to the second computer system; and
if the selected computer is selected from the third group, installing, by the managing computer, an additional software program which is lacking in the first plurality of software programs or second plurality of software programs other than common software programs installed in the selected computer.

Abstract
Standby computers are dynamically divided into groups according to the difference between the software thereof and the software required of a business system. When a computer is made available, the standby computers divided into groups by software structure are searched and an appropriate one is extracted to quickly complete the construction of the software environment. An active computer, if to be transferred to standby mode, is associated with the group having the same software structure as the business system with which the active computer has thus far operated. The active/standby states of the computers are monitored, and the standby computers are changed thereby to widen the possible range of application to other business systems, removing copy operation of disk images from the active computer to the standby computers.
