Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation mechanism for performing operations such as browsing the operation status of a web application system, setting the operation environment of a processing server, setting the operation schedule of an application, and analyzing logs and performance.

[0002]

2. Description of the Related Art In a web application system, when a client accesses a processing server and requests processing, the processing server processes the requested processing using a corresponding application. Further, the processing result data is returned to the requesting client.

[0003] Each company independently builds such a web application system according to the situation of each company. When the web application system is built in a closed environment (for example, when it is built only in one company (client)), the management of the system such as operation and maintenance is performed by the relevant system. This can be done by customizing it for the client.

[0004] However, the applications used in the web application system are diversified and the life cycle thereof is shortened.
Very difficult in terms of cost and risk,
Since various applications used in web application systems are becoming increasingly complex and sophisticated, it is difficult for one company (client) to construct its own web application system in terms of operation and maintenance in the first place. is the current situation.

[0005] Under such circumstances, a network such as the Internet is rapidly developed and expanded, and a plurality of companies (clients) share one web application system through the network (integrated web application system). Is being done. By the way, (i) in a situation where clients of a large number of companies and the like use the integrated web application system to continuously access the target application, the previous request for processing by a certain client Subsequently, when the current request is made, the processing server usually performs processing in a session different from the previous request. That is, the session is temporarily disconnected, leading to a new session.

As a result, when performing a process based on a plurality of requests, such as a process over a plurality of web pages, the client needs to hold processing result data at the time of the previous request. For example, in a business system, due to a conversation between a processing server and a client (PC), all clients need to hold information for session management and the next processing content, thus exceeding the processing capacity limit. In addition, the required time is increased.

[0007] (ii) In a situation where clients such as a large number of companies access a variety of applications using the integrated web application system described above, a single processing server performs unified processing. Therefore, the processing server must be a large server having a large capacity in preparation for simultaneous access from a large number of clients. However, concentrating the processing on only one such large-sized server is inconvenient in terms of security and reliability of the entire system, and also in terms of expandability of the system.

At present, very few integrated web application systems capable of solving the problems described in (i) and (ii) above have been realized efficiently and economically and actually operated. However, as an example, the present applicant has filed a Japanese Patent Application No. 11-185979 (June 1999).
There is a “Web application distributed session management system” that has already been proposed (filed on March 30).

[0009]

However, when the above-mentioned integrated web application system is put to practical use, in a situation where the application is complicated and sophisticated, any of a large number of clients having jurisdiction over the application is required. It is a big problem to be able to operate the web application system freely.

[0010] On the other hand, if a large number of clients have a mechanism for operation individually, the mechanism for operation becomes considerably large, which is considerably uneconomical from the viewpoint of maintenance, cost, operators and the like. Thus, there is a problem that the advantage of the integrated web application system is offset. Here, the above-mentioned operation specifically refers to, for example, browsing of the operation status of the integrated web application system by each client, setting of the operation environment of the processing server, setting of the operation schedule of the application, and analysis of logs and performance. It means that each client can easily realize environment setting and browsing of various situations according to the processing status without providing the above-mentioned large-scale mechanism for each client,
In addition, it is required that the operation can be executed by a simple operation while keeping the secret of each client.

[0011] The present inventors have intensively studied various operating mechanisms such as browsing of the operating status of the integrated web application system, setting of the operating environment of the processing server, setting of the operating schedule of the application, and analysis of logs and performance. By introducing an operation module and a communication module into the web application system, a mechanism that can easily operate according to individual situations by individual instructions from each client with jurisdiction authority is built, The present invention has been completed.

[0012] That is, an object of the present invention is to enable each client having jurisdiction over a web application to easily perform various operations such as browsing various situations and setting an environment independently. It is.
