DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed processing system comprising a plurality of computers and various terminal devices connected to a network, and by logging a user to an optimal computer, the load on a network line and the computer resources are reduced. Login distribution method that can reduce the load on the server.

2. Description of the Related Art Conventionally, in a distributed processing system, when a user performs a task, he or she selects one computer to log in from a plurality of computers holding target business data, and uses a user name as data from a terminal device. Make a login request to have. At that time, the choice of the computer to log in was left to each user.

Next, a user inputs a password from a terminal in response to a password input request from a computer to log in, and transmits the password to the computer to log in. If the password is registered in advance, the login to the computer succeeds.

[0004] After successful login, the user sequentially generates a plurality of processing requests to process business data in accordance with the intended business procedure. Each processing request that occurs is
Each is sent to the login computer and executed, and the execution result is returned to the terminal device.

[0005]

In the above-described conventional log-in computer selection method, since the log-in computer is arbitrarily determined by the user, the computer is not necessarily the most suitable computer for actually executing the processing request. There was the disadvantage that execution was inefficient. For example, processing requests that need to process a large amount of data at high speed are more efficient if executed by a computer system with a large memory capacity, and processing requests that require special operations are specialized for them. It is more efficient to execute the program on a computer system having the set of instructions.

An object of the present invention is to provide a method for automatically selecting a login computer capable of executing a plurality of processing requests constituting a business as a whole in the most efficient manner.

Calculating the suitability value of each computer C1, C2, C3 for business G, T [G1] [C1] = H [G1] [P1] × N [P1] [C1] + H [G1] [P2] × N [P
2] [C1] + H [G1] [P3] × N [P3] [C1] = 10 × 5 + 5 × 4 + 1 ×
1 = 71 T [G1] [C2] = H [G1] [P1] × N [P1] [C2] + H [G1] [P2] × N [P2]
[C2] + H [G1] [P3] × N [P3] [C2] = 10 × 3 + 5 × 1 + 1 × 1 =
36 T [G1] [C3] = H [G1] [P1] × N [P1] [C3 + H [G1] [P2] × N [P2]
[C3] + H [G1] [P3] × N [P3] [C3] = 10 × 2 + 5 × 2 + 1 ×
5 = 35 Therefore, T [G1] [C1]> T [G1] [C2]> T [G1] [C3], and the processing request P predicted to occur in the business G1
1, C1 is selected as the computer on which P2 and P3 can execute most efficiently.

If the task is G2, T [G2] [C1] = H [G2] [P1] × N [P1] [C1] + H [G2] [P2] × N [P2]
[C1] + H [G2] [P3] × N [P3] [C1] = 1 × 5 + 1 × 4 + 3 × 1
= 12 T [G2] [C2] = H [G2] [P1] × N [P1] [C2] + H [G2] [P2] × N [P2]
[C2] + H [G2] [P3] × N [P3] [C2] = 1 × 3 + 1 × 1 + 3 × 1 =
7 T [G2] [C3] = H [G2] [P1] × N [P1] [C3] + H [G2] [P2] × N [P
2] [C3] + H [G2] [P3] × N [P3] [C3] = 1 × 2 + 1 × 2 + 3
× 5 = 19 Therefore, T [G2] [C3]> T [G2] [C1]> T [G2] [C2], and C2 is selected as the login destination computer for the same reason.

After selecting the login destination computer, the login destination selection means 11 transfers the login request to the login management means 21-1 to 21-3 of the computer.
