DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
FIG. 1 is a block diagram illustrating a configuration of a network system to which an information processing apparatus according to the first embodiment of the present invention can be applied. For example, the information processing apparatus 102 and information processing via a local area network (LAN) 101 are illustrated. This corresponds to the case where the device 110 and the client 113 are connected so as to be communicable. In some cases, the network is widely connected to an external Internet via a LAN.
[0023]
In the figure, reference numeral 102 denotes an information processing device (server) to which a normal workstation, a personal computer (a control board having a so-called CPU, ROM, RAM, etc.) and its peripheral devices (hard disk, keyboard, mouse, display device) are connected. Device). Reference numeral 103 denotes an operating system (OS) which manages each resource of the information processing apparatus. A WWW server 104 is a server processing mechanism that performs certain processing in response to a request from the client 113.
[0024]
In the information processing apparatus 102, the information processing apparatus can function as a server due to the presence of the WWW server mechanism. A low-level processing mechanism that is further evoked by the WWW server 104 with an adapter 105, and mediates between the applications 106, 107, and 108 and the WWW server 104. In other words, when a request from a plurality of clients 113 enters the WWW server 104, it has a function of determining which application is requested to perform processing. In the present embodiment, it is shown that three identical applications 106, 107, and 108 exist in the server.
[0025]
Here, the application is generally software for realizing high-functional processing such as personnel processing and accounting processing, and uses the most resources in the server and increases the load on the server. Reference numeral 109 denotes a software DB server, which will be described in detail later. An information processing apparatus 110 exists on the same LAN, and includes an operating system 111 and an application 112 similar to the applications 106, 107, and 108.
[0026]
Reference numeral 113 denotes a client, which is equipped with software that can request the server to perform processing by designating the location of the server using, for example, a browser.
[0027]
As a flow of normal business processing, when the client 113 requests the information processing apparatus 102 as a server to perform processing, the WWW server 104 activates the adapter 105, and the adapter 105 further requests processing from the application. At this time, it is general that the adapter 105 determines which application among the plurality of applications 106 to 108 is to be requested according to a certain rule.
[0028]
That is, there are methods such as requesting in order, or requesting to be distributed evenly using random numbers. Each of the applications 106 to 108 performs processing according to the request from the client 113 and responds to the client 113 via the server 102.
[0029]
FIG. 2 is a diagram for explaining a data processing mode between the server 102 and the client 113 shown in FIG. 1, and corresponds to a typical request and response example.
[0030]
In the figure, 201 indicates processing on the client 113, 202 and 203 indicate on which software on the information processing apparatuses 102 and 110, respectively, and processing 201 is illustrated in FIG. It indicates that the process is performed by the browser of the client 113 shown. A process 202 indicates that the adapter 105 processes a request via the WWW server 104 and the WWW server 104 in the information processing apparatus 102. A process 203 indicates a process in the applications 106, 107, 108, and 112 shown in FIG. Hereinafter, 204 to 210 are timings corresponding to requests or responses, respectively.
[0031]
First, at timing 204, the client 113 accesses the information processing apparatus (server) 102. If this is the first access, user authentication is requested here. At timing 205, a request based on timing 204 is received and a response is made to the client 113 side with a screen for user authentication.
[0032]
At timing 206, the operator of the client 113 inputs the user ID and password on the user authentication screen, and makes the next request to the server 102 again.
[0033]
On the other hand, if the server 102 confirms that the correct user ID and password are input at the timing 207, the server 102 requests the application for subsequent processing at the timing 208.
[0034]
At timing 209, processing in the application is shown, and the application determined here is in charge of a series of processing of the same user.
[0035]
However, when a large number of clients 113 request processing at the same time, the number of requests for the application also increases, and the server 102 is loaded and the processing speed is slow. There may also be a queue. Therefore, at the timing 207 and the timing 208 shown in FIG. 2, the process shown in the flowchart of FIG. 3 is executed in order to provide a comfortable process even for the specific user even in the above state.
[0036]
FIG. 3 is a flowchart illustrating an example of a data processing procedure of the information processing apparatus according to the first embodiment of this invention. In addition, (301)-(310) shows each step.
[0037]
First, in step (301), the user ID and password input from the operator of the client 113 are received in the adapter 105. In this state, in step (302), the VIP file is read and in step (303). The file contents of the user ID and password are compared.
[0038]
If it is determined in step (304) whether the user ID input in step (301) exists in the VIP file and the same user ID exists, the user of this client Is a user who has authority with respect to server access, and in step (305), the application 112 on the other server 110, which has a particularly low load, is requested to perform processing. Become.
[0039]
On the other hand, if it is determined in step (304) that the user ID input in step (301) does not exist in the VIP file, the general process is performed, and the process proceeds to step (306), where a general password is entered. Read the file.
[0040]
Next, in step (307), the password file is compared with the input user ID and password, and in step (308), it is determined whether the passwords match, and it is determined that the passwords do not match. In this case, the server 102 responds with an error screen to the client user who has input the user ID (309).
[0041]
On the other hand, when it is determined in step (308) that the passwords match, in the same way as usual, in step (310), the processing is requested to one of the applications 106 to 108 and executed in response to the request from the user. The information obtained in this manner is returned to the user (file search response, application activation response), and the process is terminated.
[0042]
[Second Embodiment]
In the network system shown in the first embodiment, a system configuration in which software that is a database server is installed on the server 102 to perform various business processes by an application that uses an unspecified user on the network as a client. In many cases. Therefore, a second embodiment for distributing the server load when a database is used will be described below.

First, in step (401), the user ID and password are received from the client 113, and the adapter 105 grasps the values, and at the same time, in step (402) grasps the user database table from the internal database server. Search is performed with the user ID set to Key. In step (403), it is determined whether the search result is “0”, that is, whether there is a user. If it is determined that the user does not exist, an error is returned in step (404). To do.
[0045]
On the other hand, if it is determined in step (403) that the user exists, the user record obtained from the user database is analyzed in step (405), and it is evaluated whether the input password is valid or not. If it is evaluated, an error response is made in step (405).
[0046]
On the other hand, if it is determined in step (405) that the user is a valid user, the user record is analyzed in step (406) from the user record to obtain the user authority.
[0047]
Next, in Step (407), it is determined whether or not the user is a general user based on the user authority obtained in Step (406). If it is determined that the user is a general user, any application on the general server 102 is determined. Request processing and end the processing.
[0048]
On the other hand, if it is determined in step (407) that the user is a more authorized user, it is determined in step (408) whether the privileged person level is the highest privileged person A level. Proceed to (411), request processing to a server (not shown) capable of high speed processing, and if NO, in step (410), request processing to the high speed server and end the processing.
[0049]
As a result, the highest authority can be processed in the step (411) without the data processing waiting time to which the highest speed server is assigned and requested.
