DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to an automatic connection system in which a client automatically connects to a predetermined server, a client, and a recording medium.

[0002]

2. Description of the Related Art Conventionally, when a client / server system for a core business process with a large traffic volume is constructed, the processing capacity of one server is limited.

[0003] In this case, there are two types: a function distribution arrangement in which processing is distributed for each server, or a data distribution arrangement in which a master is divided in a certain unit and the same processing is distributed under the same conditions.
The following configurations are possible.

[0004]

In the former function-distributed arrangement, when there is a process with a high access load, the load is concentrated on a specific server, and when the function is changed later, hardware is included. There is a problem that the system configuration needs to be reviewed.

In the case of the latter data distribution arrangement,
From the viewpoint of the client, there is a problem that the user needs to be aware of which server should be connected to perform the processing. An object of the present invention is to solve the above problems by realizing automatic connection to a specific server in which a load is distributed without a user being aware in a client / server system configuration.

[0006]

Means for solving the problem will be described with reference to FIG. In FIG. 1, a client 1 is for connecting to a predetermined server and performing various processes, and includes a home server search means 4, a home server connection means 5, a connection information file 6, a host file 7, and the like. Is what is done.

The common management server 11 manages the user management file 15. The business processing server 20
It performs business processing. Next, the operation will be described.

[0008] The home server search means 4 constituting the client 1 refers to the connection information file 6 based on the ID at the time of login, and instructs the home server connection means 5 when the connection information is within the validity period to make the connection. It connects to the business processing server 20 corresponding to the information, and on the other hand, connects to a specific common management server 11 when the expiration date is not exceeded, receives the download of the connection information, registers it in the connection information file 6 and the host file 7, and registers the home information. The server connection means 5 connects to the business processing server 20 corresponding to the connection information.

Further, all connection information on the system is registered in the common management server 11, and a plurality of business processing servers 20 corresponding to the connection information are provided to achieve load distribution.

[0010] Further, a program having the home server searching means 4 and the home server connecting means 5 is stored in a storage medium. Therefore, it is possible to automatically connect to a specific server (the business processing server 20) which achieves load distribution and the like without the user being conscious of the client / server system configuration.

In FIG. 2, S1 logs in. In this method, an employee (user) of a company goes to work in the morning, turns on the power of the client 1 in FIG. 1, and tries to log in to the home server by inputting a password and a user ID from a log-in screen.

In S2, it is determined whether there is connection information corresponding to the ID. This is done by searching the connection information file 6 shown in FIG. 4 based on the user ID input in S1, and determining whether there is a corresponding one. In the case of YES, the process proceeds to S3. N
In the case of O, the process proceeds to S9.

In step S3, the current date and time are obtained. In S4, it is determined whether the connection information is within the validity period. This is because the current date and time obtained in S3 is the connection information file 6 in FIG.
It is determined whether it is within the validity period in the connection information extracted from. Y
In the case of ES, since the connection information is found to be valid, S5
To log in to the home server based on the connection information (search the host file 7 in FIG. 5 based on the home server ID in the connection information file 6 to extract the IP address, and send a message to the IP address) Then, the user logs in to the business processing server 20 of the IP address). On the other hand, NO
In the case of, it is determined that the validity period of the connection information file 6 in the client 1 has expired, so the process proceeds to S9.

In step S6, it is determined whether or not the login is successful.
In the case of YES, the login is successful, so the user information is acquired in S7, and the process proceeds to S8. On the other hand, if NO, an error process is performed in S14, and the process ends.

In step S8, it is determined whether the user information has been obtained. If YES, the process ends. On the other hand, in the case of NO, the process proceeds to S15. In S15, since it was determined that the user information could not be obtained in S8, the login dialog is displayed (the server ID can be input).

At S16, the user logs in (inputs a user ID, a password, and a server ID to log in). S17 is
Login with the input server ID. And S
Return to step 6 and repeat.

In step S9, the user logs in to the common management server.
This is because, in the case of NO in S2, it is determined that the user ID is not registered in the connection information file 6 of FIG.
In the case of NO of 4, the user ID is registered in the connection information file 6 of FIG. 4, but it has been found that the expiration date has expired, so the user logs in to the common management server 11 (the connection information of the user ID, Alternatively, log in to obtain the latest connection information for updating the expired connection information).

In step S10, it is determined whether or not the login is successful. In the case of YES, the process proceeds to S11. In the case of NO, in S13, it is determined whether there is connection information corresponding to the ID,
If YES, the process proceeds to S5, and if NO, S15 in FIG.
Proceed to.

At S11, since the login is successful at YES of S10, the connection information corresponding to the ID is obtained. This is because the common management server 11 logged in in S9
The connection information corresponding to D is retrieved and retrieved from the user management file 15 and returned to the client 1.

In S12, the client 1 updates the connection information. This is because the connection information returned in step S11 corresponds to the user I in the connection information file 6 of the client 1.
D, the expiration date and the home server ID are updated, and the home server ID and the IP address in the host file 7 are updated. Then, the process proceeds to S5, and logs in to the home server based on the updated connection information.

As described above, when the user logs in the client 1, the connection information file 6 is searched based on the user ID, and if the connection information is within the validity period, the user logs in to the home server (business processing server 20). When the process is started, if the user ID is not registered or the connection information has expired, the user logs in to the common management server 11 and receives the latest download of the connection information to update the connection information in the client 1. Then, based on the updated connection information, the user logs in to the home server and starts business processing, so that each user operates the client 1 and assigns his / her home server (business processing server 20).
Log in to the common management server 11 only once in the morning when the power is turned on, and thereafter directly to the home server (business processing server 2).
0), it is possible to log in and perform business processing. In a client / server system configuration of a data distributed arrangement type, each client connects without being aware of the home server, and business processing is not concentrated. It is possible to execute.

When the common management server 11 is not operating (when login is impossible), login is attempted based on the information at the time of the previous connection held in the client local. If there is no client local information, the user directly specifies the server name and logs in.
