Next, it is determined whether or not the memory usage rate exceeds 80% (step S23). If any of them is YES, the performance information management unit 201 of the management server 101 needs to relocate the application AP1. (Step S24), and requests the application to be relocated. In the second example, the performance condition determination unit 304 of the server processing the application AP2 first obtains the relocation conditional expression of the application AP2 from the relocation conditional expression table 307 (step S31), and then uses the CPU. It is determined whether the rate exceeds 50% (step S32), and then it is determined whether the disk usage rate exceeds 80% (step S33). If both are YES, the performance information of the management server 101 is determined. The management unit 201 is notified that the application AP2 needs to be relocated (step S34).
[0032]
FIG. 14 shows another example. When the CPU usage rate exceeds 40% or the memory usage rate exceeds 70% and the disk usage rate exceeds 60%, the application relocation is performed. Request. First, the server performance condition determination unit 304 acquires the relocation conditional expression of the application from the relocation conditional expression table 307 (step S41), and subsequently determines whether the CPU usage rate exceeds 40% ( In step S42), if YES, the performance information management unit 201 of the management server 101 is notified that the application needs to be relocated (step S45). If the determination in step S42 is NO, then it is determined whether the memory usage exceeds 70% (step S43), and if NO, the process ends. If the determination in step S43 is YES, it is next determined whether or not the disk usage rate has exceeded 60% (step S44). If the determination is YES, the performance information management unit 201 of the management server 101 sends the relevant application to the management server 101 again. A notification that the arrangement is required is sent (step S45), and a request is made to relocate the application.

Next, processing for distributing and installing an application, deleting an application, and relocating an application will be described with reference to FIGS.
[0034]
FIG. 17 shows the flow of processing when a new application is installed. In FIG. 17, a system administrator registers applications to be installed in the management server 101, specifies the number of applications to be installed in the system, and specifies conditions for application distribution or relocation. Next, the management server 101 uses the optimum server determination unit 203 to determine the specified number of AP servers suitable for installing the application, and transmits an application installation instruction to the AP server. The AP server that has received the installation instruction notifies the management server 101 of the completion of preparation. The management server 101 push-distributes the application and installs it on the AP server. Also, environment setting information such as an inappropriate conditional expression and a storage path is transmitted at the same time as the application. When the installation is completed normally, the AP server notifies the management server that the installation has been completed normally. The management server 101 that has received the completion notification transmits an application start request to the application start / stop processing unit 305 of the AP server. Upon receiving the activation request, the application activation suspension processing unit 305 activates the application and notifies the management server 101 that the application has been activated. The management server 101 that has received the start completion notification stores and updates the information on the started application in the AP table 401, and notifies the front server 103 of the information of the newly added application. The front server 103 updates the distribution table 501 based on the notified information, and notifies the management server 101 that the update has been completed normally. If the installation fails during the installation process, the AP server notifies the management server 101 that the installation has failed. The management server 101 determines an optimal AP server from the remaining AP servers being managed, and transmits an installation instruction.
[0035]

The AP uninstall management unit 206 notifies the AP uninstall processing unit 303 of the AP server on which the application to be deleted is running, of an application deletion request. The notified AP uninstallation processing unit 303 stops the application and uninstalls the application. When the uninstallation is completed, a completion notification is sent to the AP uninstallation management unit 206. Upon receiving the completion notification, the AP uninstall management unit 206 deletes the information of the deleted application from the AP table 401 and notifies the front server 103 that the application has been deleted. The notified front server 103 deletes the information of the deleted application from the distribution table, and transmits a completion notification to the AP uninstall management unit 206.
FIG. 19 shows the flow of processing when the application is rearranged. In FIG. 19, the AP server periodically collects performance information by the performance information collection unit 301 and determines whether or not the performance condition determination unit 304 satisfies the reallocation condition formula of the application being processed. If the relocation condition expression is satisfied, the AP server notifies the performance information management unit 201 of the management server 101 of the fact. Further, the FCS performance measuring unit 202 determines whether the performance information of the FCSs 109 and 110 does not exceed the specified threshold value, and notifies the performance information management unit 201 if it does. When the performance information management unit 201 receives the notification, the optimal server determination unit 203 determines an appropriate AP server for relocating the application. If an appropriate AP server exists, the relocation time specified by the system administrator at the time of distribution is acquired from the AP table 401, and the application is relocated at that time. When relocation is performed, the application is installed on the selected AP server in accordance with an instruction from the AP installation management unit 205. If the installation is successful, the storage path switching unit 204 acquires the storage path of the AP server on which the application is currently running from the AP table 401, converts the storage path into the path of the destination AP server by the storage path table 403, and To the AP server. The AP installation processing unit 302 of the notified AP server sets the notified storage path to the data path of the application. When the path is set normally, the AP installation processing unit 302 notifies the AP installation management unit 205 of the management server 101 that the process has been completed normally. The management server 101 transmits an application start request to the application start / stop processing unit 305 of the AP server. Upon receiving the activation request, the application activation suspension processing unit 305 activates the application, and notifies the AP installation management unit 205 that the application has been activated normally. Upon receiving the notification, the AP installation management unit 205 updates the AP table 401 and transmits an application deletion request to the AP uninstall management unit 206. The AP uninstall management unit 206 transmits a deletion request to the AP uninstall processing unit 303 of the AP server before moving. Upon receiving the deletion request, the AP uninstallation processing unit 303 uninstalls the application, and transmits the deletion to the AP uninstallation management unit 206.
