The present invention relates to a middleware system and a method of operating the same, and more particularly, to a system and a method for efficiently using a server resource to process a task received from a user.

In recent years, complex operations have to be performed in large quantities, resulting in many tasks that are difficult to handle with a few small server resources. These tasks can take hours to tens of hours to complete a task with a few servers. Therefore, a middleware system using clustering has been developed as a method for processing tasks requiring such a large amount of operations.

1 is a diagram illustrating an example of a middleware system using clustering according to the prior art.

As shown in the drawings, the middleware system using clustering according to the prior art allocates and processes one job to a plurality of job servers, thereby distributing the jobs in a plurality of job servers and processing them in parallel to speed up the job processing speed. It is to improve it. In the figure, the configuration of a job server for processing two jobs, job A (job A) 110 and job B (job B) 130 is shown. Through such a configuration, it is possible to expect a significant improvement in performance compared to performing work on one server.

However, as shown in the figure, the job server group 120 for processing the job A 110 and the job server group 140 for processing the job B 130 are each separated, and the job server group ( 120 processes only job A 110 and job server group 140 processes only job B 130. Thus, even if job A 110 is terminated and all servers in job server group 120 are all idle, job B 130 processes only job server group 140 to effectively use idle resources. There was a problem that can not.

In particular, in order to process the job B 130 in the server of the job server group 140, before the processing of the job B 130 begins, the task of the job B 130 must be divided in advance to each server. As a result, it was difficult to dynamically allocate the server of some of the job server groups 120 to process the job B 130 while the job B 130 was being processed.

In addition, if there are separate applications for processing task A 110 and task B 130, the process B 130 may be processed by some idle resources among servers included in task server group 120. In order to do this, there is an inconvenience in that an application for processing task B 130 must be directly installed in the idle resource and allocated to process some of task B.

Therefore, if a plurality of job servers can be managed dynamically to effectively use idle resources, efficiently manage applications for processing each job, and allocate jobs based on the platform on which each application can operate, You will be able to use the same server resources more efficiently. Accordingly, in the present invention, by managing a plurality of job servers, it is possible to allocate the job server to the job required dynamically, and by managing the application for processing each job, processing in each server without the inconvenience of application installation, etc. An object of the present invention is to propose a middleware system capable of processing possible tasks and a method of operating the same.

The present invention has been made to improve the prior art as described above, and an object of the present invention is to provide a middleware system capable of processing a work received from a user by using server resources efficiently.

In addition, an object of the present invention is to store information about an application for processing each job, so that a job server suitable for processing each job can be found and assigned to the job.

In addition, the present invention stores the information about the platform on which the application for processing each job can operate, and by storing the information about the platform of each job server, in the application to the job server capable of operating each application Its purpose is to be able to allocate work for processing.

In addition, the present invention stores the minimum requirement information of the job server that the application for processing each job can operate, and the system specification information of each job server to store the minimum requirement specification that can operate each application An object of the present invention is to make it possible to assign a job processed by the application to a satisfactory job server.

In addition, the present invention aims to give priority to each job and to process the job according to the priority, so that important jobs can be processed quickly.

In addition, the present invention checks whether an application for processing the job is installed in the job server when assigning the job to the job server, and installs an application if the application is not installed. The goal is to be able to allocate work effectively without work.

In addition, an object of the present invention is to classify and manage a job into a plurality of tasks, and to assign each task to a different job server so that the work can be distributedly processed.

In addition, an object of the present invention is to set up some of the job server as a dedicated job server for processing a specific job, to arrange a minimum job server to the specific job, so that important tasks can be completed as soon as possible. do.

In addition, an object of the present invention is to exclude some of the job servers not to be used for specific job processing, thereby minimizing the probability of problem occurrence by not assigning a specific job to a job server that causes a lot of problems when processing a particular job. It is done.

In addition, an object of the present invention is to allow the task to be assigned to another task server when the task server to which the task is assigned cannot complete the assigned task, so that the task can be completed even if a problem occurs in the server. It is done.

In addition, an object of the present invention is to be able to limit the maximum number of job servers that can be assigned to a particular job, to prevent the job is delayed by assigning more work servers than necessary to a particular job.

In order to achieve the above object and to solve the problems of the prior art, the middleware system according to an embodiment of the present invention receives a task processing request, a plurality of job servers to process the task (task) in response to the task processing request receiving job information about a job to be processed from a worker and a user, dividing the job into one or more tasks based on the job information, and among the tasks among the job servers And a control server that selects a job server capable of processing one and transmits a task processing request about the task to the selected job server to process the task.

In addition, the middleware system according to another embodiment of the present invention manages a job (user) received from the user (job), a job management unit (job management unit) for selecting a job to be processed, a plurality of job servers (worker) To manage worker status information received from the server, and to process each job received from the user and a resource management unit for assigning the selected job to the job server. And an application control unit for managing an application and transmitting an application for processing the selected job to the assigned job server.

In the present invention, the middle ware system is not a system for directly processing a job, but a system for receiving a job from a user who wants to process a job, managing the job server to process each job, and processing the result. In other words, the user feels the same as processing a job in one job server, but can perform a job quickly by performing a job in parallel using many job servers. In the related art, a plurality of job servers are previously set to distribute one job by using a clustering method. In the present invention, a user may dynamically assign each job to a plurality of job servers. Efficiently use job servers to process jobs.

2 is a block diagram showing the configuration of a middleware system according to an embodiment of the present invention.

As shown in the figure, the middleware system according to an embodiment of the present invention includes a plurality of job servers 210 and a control server 220. The job server and the control server may be connected to each other through a communication network to exchange data.

The work server 210 receives a task processing request and processes a task in response to the task processing request. The task processing request may include a task to be processed by the job server 210 and application information about an application required to process the task. The application may be included in the application information in the form of a program executable on a computer. The application information may include an application ID and an application version, and check whether the application corresponding to the application identifier and the application version is installed in the job server 210, and install the application. If not, the application may be requested to the job server 220 to be downloaded and installed. Checking whether the application is installed or not is automatically performed when the task processing request is received. Therefore, the server administrator does not need to install a separate application directly on the job server according to the type of task to be processed. It can be easily used as an effect.

In addition, the job server 210 collects job status information (worker status information) related to its status and transmits it to the control server 220. The job server state information may include system specification, platform, and load information of each job server. Since each job server may have a different system specification, platform, and load, the job server may be selected to transmit the job server state information to the control server 220, thereby selecting a job server capable of effectively processing a task in the control server 220. You can refer to it.

After processing the task in response to the received task processing request information, the job server 220 transmits information on the processing of the task to the control server 220. The information may include information on the processing result of the task, to allow the job server to check the result of the task processing, and to include information on whether the job server has been processed normally. In operation 220, the task may be reassigned to another job server 210. In addition, by including information on the time spent for the task processing in the information, it is possible to check the time required to process the task for each job server 210, so that the task server 210 more efficiently To be assigned to.

The control server 220 receives job information about a job to be processed from a user, divides the job into one or more tasks based on the job information, and performs the job. The server may select a job server capable of processing one of the tasks, and transmit a task processing request regarding the task to the selected job server to process the task.

The control server 220 manages a plurality of job servers 210 and receives job server state information of each of the job servers 210 from each job server 210 to correspond to each job server 210. Save it. The job server 210 managed by the control server 220 may be registered by a system administrator using information for identifying a job server such as an Internet address (IP address) of each job server 210, or each job server. In operation 210, a module capable of communicating with the control server 220 may be installed, and the control server 220 may be requested to allocate a task to be registered with the control server 220.

In addition, the control server 220 receives a job and job information about the job from the user, the job information may include application information about an application for processing the job. The application information may include platform information on which the application can operate, minimum requirement information of a server on which the application can operate, information such as an application identifier, an application version, and the like.

The control server 220 selects a job server 210 in which the application is installed and operates using the application information, and assigns a task of the job to the selected job server. In order to select the job server 210, job server state information of each job server 210 may be used. For example, when the minimum requirement information included in application information requires 512 MB of memory, the job server may be used. With reference to the system specification information included in the status information, one of the job server 210 having a memory of 512MB or more may be selected as the job server 210 to which the task of the job is assigned.

In addition, the control server 220 is preferred to the job server 210 with the lowest system load by using load information included in the job server status information in order to select the job server 210 to which the task is assigned. You can assign a task. A task allocated from the control server 220 to the job server 210 is a unit configuring a job received from a user, and each task must be processed in parallel to be effective in the middleware system of the present invention. Can be processed as

The control server 220 may set a part of the job server 210 to process only a task of a specific job. In this configuration, the control server 220 does not allocate a task other than the task of the specific task to the set task server in assigning a task. In this configuration, some job servers 210 process only the task of the specific job, so that even if the job server 210 is used flexibly, at least the job server 210 may perform the task of the specific job. Because it can be used for processing, it has the effect of ensuring minimal completion time for critical tasks that need to be processed quickly.

In addition, the control server 220 may limit the maximum number of job server 210 for processing a particular job. The maximum number may be input from a system administrator managing the control server 220. When the maximum number of job servers is allocated to the specific job, no more servers can be allocated, so that the specific job is a server resource. You can use them all to prevent them from processing other tasks in advance.

3 is a block diagram showing an internal configuration of a middleware system according to an embodiment of the present invention.

As shown in the figure, the middleware system 301 according to an embodiment of the present invention may include a job management unit 310, a resource management unit 320, and an application control unit ( application control unit) 330. The job management unit 310 manages a job received from a user and selects a job to be processed. The job manager 310 may receive job information about each job together with the job from the user, and store the job information corresponding to each job. The job information may include application information about an application that processes each job. The application information may be input from the user, and may include information such as an application, platform information on which the application can operate, minimum requirement information of a server on which the application can operate, an application identifier, and an application version. . The application may be a program executable on a computer, installed and executed in the job server 302 to process the job, and the application information may be stored and managed in the application controller 330.

In addition, the job management unit 310 may receive and store priorities for each job in correspondence with each job, and when the plurality of jobs are to be processed, the job having a high priority must be processed first. Choose what to do. The priority may be input from the user, and in this case, the user may be charged at a high cost for a job having a high priority, so that the user may have to pay a high cost and process quickly as needed. Can be.

The task manager 310 may classify and manage each task into a plurality of tasks. The task is a component constituting each job, each task in the same job must be able to be processed independently of each other to process the tasks in parallel, thereby completing the entire job in a short time using a plurality of job server 302 Can be. Classifying the task into tasks may be set in advance when a user inputs a task, or in the case of a task corresponding to a predetermined kind of task, the task may be classified into a plurality of tasks according to a predetermined task. The task is completed only when all of the classified tasks are completed.

A resource management unit 320 manages worker status information received from a plurality of work servers 302 and assigns the selected work to the work server 302. (assign) The job server state information is received from the job server 302 collected information about its own state through the communication network, the resource management unit 320 requests the job server status information from the job server 302 to receive Alternatively, the job server 302 may periodically transmit the job server status information to the resource manager 320.

In addition, the job server status information managed by the resource manager 320 may include platform information of each job server 302. The platform information may include information about an operating system and a version of the operating system. As an application in the form of a program executed on a computer, a platform on which each application can operate is determined. This is because the file system for storing applications is different for each platform, and the method of processing the commands of each application is different. For example, it is not possible to run an application running on Windows XP on a job server 302 with a Linux based platform unless it is running a separate emulator. Therefore, the resource management unit 320 manages the platform information of each job server 302, so that when assigning each job to the job server 302, a job having a platform that can operate an application for processing each job The server may be selected as a job server to which the job is assigned. Therefore, only by installing the job server 302 having a variety of platforms in advance, it is possible to run a variety of applications that operate on a variety of platforms, it is effective to process a variety of tasks.

The job server state information managed by the resource manager 320 may include system specification information of each job server 302. The system specification information may include the number of the central processing unit, the speed of the central processing unit, the memory capacity, the hard disk capacity, and the like. In addition, any information indicating the specification of the job server 302 may be included. . In order for an application to operate to process each task, a minimum system specification is required for each application. For example, some applications can easily operate when the speed of the CPU is 1.5GHz or more, and some applications can easily operate when the memory is 1GB or more. This is because, depending on the nature of the application, there are applications that use a lot of memory, and there are applications that require fast computational processing of the CPU. Accordingly, the resource manager 320 processes the application to the job server 302 that satisfies the minimum requirement specification information among the plurality of job servers 302 based on the minimum requirement information included in the application information of each application. You can assign tasks to do this. As described above, according to the present invention, by assigning a job to a job server 302 that can operate optimally, each application has an effect of efficiently using a given job server 302 resource.

In addition, the job server state information managed by the resource manager 320 may include load information of each job server 302. The load information is information on how much resources such as CPU and memory of each job server 302 are used. The job server 302 having a high load has a higher job processing efficiency than the job server 302 having a low load. Since the fall, the job management unit 320 to assign the job to the job server 302 with the lowest load as possible.

In addition, the resource manager 320 may set a part of the job server 302 as a dedicated job server for processing only a specific job, and assign only the specific job to the dedicated job server. When the dedicated job server is set up as described above, the dedicated job server processes only the specific job, and when there is no specific job, the dedicated job server waits idle even if there are other jobs. Therefore, the specific job can be processed quickly at any time, and even when a large number of job servers 302 are used, no other job is assigned, so that the specific job can be processed most quickly. In the case of setting up a dedicated work server in this manner, a separate fee may be charged to the user so that the user pays the cost and uses the dedicated work server as needed.

In addition, the resource manager 320 may set some of the job servers 302 as an exclusion job server that does not process a specific job, and may not assign the specific job to the exclusion job server. Even in the case of the job server 302 which does not have enough to process a specific job, such as platform and system specification, a certain job may not be processed properly or may be processed slowly. In such a case, by setting a job server 302 that does not properly handle the specific job as an exclusion job server, a user or an administrator prevents the specific job from being assigned to the exclusion job server, thereby making the specific job normally. The specific job may be assigned only to the job server 302 which processes quickly.

When the job server 302 which has assigned a job cannot complete the selected job, the resource manager 320 assigns the selected job to another job server 302. Therefore, even when the job server 302 has a problem and the job is not normally terminated, another job server 302 can be used to complete the job. Thus, in case of a system problem, without a separate reassignment job, The effect is to complete the task.

In addition, when each task is completed, the resource manager 320 may receive information on task completion from the task server 302 and use it to allocate the next task. For example, by receiving information on the time taken to process a job at each job server 302, it is possible to check the time taken by each job server 302 to process the job. The job may be assigned to a job server 302 which processes the job quickly.

In addition, the resource manager 320 may limit the maximum number of job servers 210 that process a specific job. The maximum number may be input from a system administrator managing the control server 220. When the maximum number of job servers is allocated to the specific job, no more servers can be allocated, so that the specific job is a server resource. You can use them all to prevent them from processing other tasks in advance.

An application control unit 330 manages an application for processing each job received from the user, and transmits an application for processing the selected job to the assigned job server. In order to manage the application, the application controller 330 may store application information received together with the job by the job manager 310. The application information may include an application, an application identifier, an application version, and the like, and any information may be included as long as the characteristics of the application can be identified.

The application control unit 330 stores each application and application information in correspondence with a job to be processed in each application. When the resource management unit 320 assigns each job to the job server 302, the job server to which the job is assigned ( The application may be sent to 302. In this case, the application may be directly transmitted to be installed and used by the job server 302 to which the job is assigned. In this case, whether the application is installed in the job server 302 to which the job is assigned and The application can be installed to process the work regardless. In addition, more preferably, instead of unconditionally transmitting the application, the application identifier of the application and the application version of the application are transmitted to the job server 302 to which the job is assigned, and the job server 302 to which the job is assigned. If there is no application corresponding to the application identifier and the application version in the request to the application control unit 330, the application control unit to transmit and install the application to the job server 302 to which the job is assigned. have. Applications and application information managed by the application controller 330 may be updated by the user from time to time.

4 is a diagram illustrating an example of job server state information of a middleware system according to an embodiment of the present invention.

As shown in the figure, the job server status information may include the name of the job server, the number of CPUs, the CPU speed, the memory capacity, the hard disk capacity and the platform information.

The number of CPUs, CPU speeds, memory capacities, and hard disk capacities shown at 410 are included in the system specification information and indicate the system specifications of each work server. Using the system specification information, the middleware system according to an embodiment of the present invention may select a job server capable of effectively processing each job and allocate a job. For example, if there is a job where each CPU should have a speed of 2.5 GHz or more, the job should be assigned to one of the henry job server and only one job server. In addition, hard disk usage is high, and jobs requiring hard disk space above 50 GB should be allocated to the henry job server. In this way, it is possible to select a suitable job server according to the characteristics of the job to enable efficient job processing.

In addition, the platform information shown at 420 is information about a platform installed in each job server. Since an application for processing each job is in the form of a program running on a computer, there is a platform on which each program can operate. Accordingly, in order for an application to operate, a job server having a platform capable of operating the application is required. In the present invention, a job server to which each job is assigned is selected using platform information included in the job server state information. can do.

In addition, the job server status information may include load information of each job server. The system specification information and platform information are mostly items that do not change when the job server is installed. However, the load information is items that change from time to time while the job server is operating. Therefore, the load information is frequently received and updated from the job server.

5 is a diagram illustrating an example of job information of a middleware system according to an embodiment of the present invention.

As shown in the figure, job information for each job includes a job ID, a job ID, an app version, an app version, a platform, minimum requirements, and priority information. And the like. In addition, the information representing the characteristics of the task in order to process each task may include any information.

Reference numeral 510 denotes an application identifier and an application version of an application for processing each task. By using the application identifier and the application version, it is possible to identify each application and use it to check whether the necessary application is installed in each job server.

Reference numeral 520 denotes platform information on which an application for processing each task can operate. Each application is in the form of a program executable on a computer. In order to execute a computer program, a computer having a platform capable of operating the program must exist. Therefore, in the present invention, by storing the platform information that the application can operate for each application for processing each job, to assign the job to a job server equipped with the platform.

Reference numeral 530 denotes minimum requirement information for operating an application for processing each job. The application for processing each task has different characteristics according to the characteristics of each task. Some applications require fast CPU operations, while others require large amounts of memory. Other applications may also require large hard disks. Therefore, according to the characteristics of each application, in order to find a job server capable of operating each application most effectively, it is necessary to store information about the system requirements of each application. As shown in the figure, the minimum requirement may include a limitation on some or all of the information included in the system specification.

Reference numeral 540 denotes the priority of each job. In the present invention, priority can be given to each job, so that when a plurality of jobs must be processed at the same time, a job having a high priority can be preferentially processed. The priority may be automatically determined according to the type of job, and may be input by the user as needed.

The application information may include an application, an application identifier, an application version, and the like, and any information may be included as long as the characteristics of the application can be identified.

In operation S603, each application and application information are stored in correspondence with a job to be processed in each application. If each job is assigned to a job server in step S602, the application may be transmitted to the job server to which the job is assigned. In this case, the application identifier of the application and the application version of the application are transmitted to the job server to which the job is assigned, and the application identifier and the application version are transmitted from the job server to which the job is assigned. If there is no corresponding application, the request may be received from the job server, and the application may be transmitted to the job server for installation.
