Description

Method of Constructing Distributed Application System in Standalone Environment

technical field

The invention belongs to the distributed application system construction technology in the distributed application field, in particular to a method for constructing a distributed application system in a stand-alone environment.

Background technique

Distributed application system is a new application mode proposed in recent years. It is a system that looks like an ordinary system to the user, but runs on a series of autonomous processing units, each with its own physical memory space, with close cooperation and non-negligible Information transmission delay. When the system resources are abundant enough, the whole system can support any number of processes and dynamic expansion of autonomous processing units.

From an application point of view, a distributed application system is a set of mechanisms used to implement secure client/server computing technologies and services in an enterprise environment. Its purpose is to establish an application system framework in a distributed environment so that it can Platforms interoperate and provide transparent access to as much computing power and data as possible while achieving the goals of high performance and reliability.

In a distributed application system, different software in different computers share information with each other, and the entire system runs on multiple computers connected through a network. The application tasks to be solved are decomposed into many small parts, and then these small parts are distributed to many computers that form a distributed system for processing, and finally all these processing results are combined to obtain the final result.

In the development and design of distributed application systems, it is often necessary to debug and test the distributed application system software to be developed. At present, people mainly achieve this goal by building small-scale prototype distributed application systems. Although this method can meet the requirements of debugging and testing the distributed application system software to be developed, because this method requires multiple networked computers and multiple people to work together, the development process is complicated and the preparation period is relatively long. Long, high operating costs and costs, difficult system management and maintenance. Moreover, after the development of the entire distributed application system is completed, it is very difficult to deploy the developed distributed application system to the actual distributed application environment. All of these greatly reduce the design quality, system reliability and development efficiency of the developed distributed application system, and increase the difficulty of the development and application of the distributed application system.

Contents of the invention

The purpose of the present invention is to provide a method capable of constructing a distributed application system under a single-computer environment under the environment of a single ordinary personal computer, so as to overcome the above-mentioned disadvantages.

To achieve this purpose, the present invention is characterized in that: virtual machine technology is used to realize the virtualization of the physical structure of the autonomous processing unit in the distributed application system on a common single computer, and all these are virtualized by the virtual network card and the virtual switch. The autonomous processing units composed of devices are connected, and related distributed application software is developed and deployed on all autonomous processing units, so as to obtain a real distributed application system running in a stand-alone environment.

Compared with the current construction methods of various distributed application systems, this method is not only simple to operate, easy to implement, low in cost, convenient to use, and the obtained experimental results are real and highly reliable. It is highly stable and reliable, easy to maintain and manage, and can be quickly migrated to a real distributed application system environment. It can not only solve the existing research problems in the development of distributed application systems, but also speed up the development process, improve the development efficiency, ensure the quality of development, and promote the rapid transformation of research results.

Accompanying drawing is the topology diagram of the present invention.

Detailed ways

The present invention will be further described below in conjunction with the examples, but the examples should not be construed as limiting the present invention.

Concrete construction steps of the present invention are described as follows:

① Prepare a computer with high performance.

②Install the virtual machine software on the computer.

③According to the development requirements of the distributed application system, make several virtual computers with network cards on the virtual machine software as the autonomous processing unit of the distributed application system.

④ Set up a virtual switch to connect all these autonomous processing units (that is, virtual computers) to form a virtual network environment.

⑤ Deploy the relevant distributed application support environment on all the autonomous processing units, and complete the construction of the distributed application system in the stand-alone environment.

⑥Debugging and testing the developed distributed application software.

⑦ During the experiment, the virtual machine performance detection and management software can be used to monitor and manage each autonomous processing unit in the distributed application system, and relevant experimental data can be obtained in real time, which facilitates the analysis and debugging of the distributed application system.

⑧When the experiment is successful and it needs to be migrated to the real distributed application system environment, it is not necessary to redo the relevant configuration and installation work in the real autonomous processing unit, only need to use the physical network and related tools to integrate the virtual autonomous processing unit The data in the processing unit is directly copied to the corresponding autonomous processing unit in the real distributed application system environment to complete the migration work quickly.

Example:

The implementation steps of building a C0RBA-based distributed application system composed of 5 computers are as follows:

①Prepare a personal computer with high performance: the CPU is Pentium4 520J of Intel Corporation, the memory is 1024M, the hard disk is 160G, and the selected operating system is Microsoft Windows Server 2003.

② Install the virtual machine software VMware GSXServer 3.1 produced by VMware on this personal computer.

③ Start the VMware GSX Server 3.1 software, and make 5 virtual computers with network cards on it, so that each virtual computer is an autonomous processing unit in the distributed application system.

④The network connection mode of all virtual computers is set to bridge mode.

⑤Because the virtual machine software VMware GSX Server 3.1 selected here has automatically configured the virtual switch when it is installed, so in general, no more configuration is required to realize the interconnection of all autonomous processing units (that is, virtual computers) .

⑥ Deploy software related to the distributed application support environment CORBA on all autonomous processing units to complete the construction of a distributed application system in a stand-alone environment.

⑦Debugging and testing the developed distributed application software.

⑧During the experiment, VMware Virtual Center, a virtual machine performance detection management software dedicated to VMware GSX Server 3.1, can be used to monitor and manage each autonomous processing unit in the distributed application system, and can obtain relevant experimental data in real time, which is convenient for distributed Analysis and debugging of application system.

⑨When the experiment is successful and needs to be migrated to a real distributed application system environment, there is no need to redo the relevant configuration and installation work in the real autonomous processing unit, only need to use the physical network and Symantec's Norton Ghost, etc. Relevant tools copy the data in the autonomous processing unit in the stand-alone distributed application system directly to the corresponding autonomous processing unit in the real distributed application system environment to quickly complete the migration work (generally, each node is 10- 15 minutes).

The content not described in detail in this specification belongs to the prior art known to those skilled in the art.
