Disclosed is a time-series management device capable of filtering time-series data having a possibility of matching a specified search pattern and reading in the data from a storage device when performing a time-series analysis. A data accumulation unit () creates a time-series index having a feature value of a data series calculated at a specific regular time interval. In addition, a data search unit () makes a decision as to the feature value for each regular time interval included in the time-series index using an evaluation formula of a specified search condition, identifies a time period of a complying data series group, and performs a time-series analysis for only the data series of the identified time period.

A method of controlling a virtual computer system, the method comprising: obtaining, by a management computer, a load value for each of the plurality of groups, and comparing the load value against a preset threshold; identifying, a group whose load value exceeds the preset threshold as a first group; selecting, a second group from the plurality of groups minus the first group; identifying, as a migration target computer, a given physical computer out of physical computers that run virtual computers allocated to the second group; migrating, virtual computers that are provided by the migration target computer to other physical computers within the second group; changing, settings of the network switch in a manner that enables the migration target computer to operate in the first group; adding, the migration target computer to the first group; and controlling, the migration target computer to run virtual computers of the first group.

Control method for virtual machine and management computer

A method for executing component-based software includes creating a first relation between a first identifier identifying a first software component and an interface for a first container created for the first component, starting a second component defined as a substitution component for the first component when a replacement condition is met, creating a second relation between a second identifier identifying the second component and an interface for a second container created for the second component when starting the second component, changing the first identifier to the second identifier in the first relation and the second identifier to the first identifier in the second relation when starting the second component, using the first component to process requests to the first component received prior to completion of starting the second component, and using the second component to execute requests to the first component newly received after completion of starting the second component.

Methods and platforms for highly available execution of component software

An information processing system, a data update method and a data update program are disclosed. In a data base system of master-slave configuration, the update result can be accessed also on slave side with the access request immediately after the particular update. The data base system DBS includes a master DB computer and at least a slave DB computer. The slave DB computer judges from the count on an update counter table whether the update log received from the master DB computer is to be reflected in a duplicate data base or not. Thus, the lost update problem is solved while at the same time realizing a high-speed process.

Information processing system, data update method and data update program

Disclosed are a virtual computer system and method, wherein computer resources are automatically and optimally allocated to logical partitions according to loads to be accomplished by operating systems in the logical partitions and setting information based on a knowledge of workloads that run on the operating systems. Load measuring modules are installed on the operating systems in order to measure the loads to be accomplished by the operating systems. A manager designates the knowledge concerning the workloads on the operating systems through a user interface. An adaptive control module determines the allocation rations of the computer resources relative to the logical partitions according to the loads and the settings, and issues an allocation varying instruction to a hypervisor so as to thus instruct variation of allocations.

Virtual computer systems and computer virtualization programs

A system includes at least a user and a file system connected to the user through a network. An estimated write size of a write operation of the user into the file system is managed as an accumulated value. The timing of judging the limit of the disk usage amount is specified from the accumulated value and a predetermined threshold value, and the limit of the disk usage amount is judged at the specified timing, so that disk usage amount by a user may be limited and managed.

Method of controlling total disk usage amount in virtualized and unified network storage system

A method for moving files between network storages in a virtualized network storage system having multiple network storages and rebalancing the free disk spaces. It periodically judges whether to start rebalancing. Two different conditions are adopted for the determination of start: (a) an imbalance of free disk spaces and the minimum value of the free disk spaces is less than a threshold and (b) an imbalance of free disk spaces and the frequency of accesses to the system is less than a threshold. Rebalancing is performed until the difference in free disk spaces falls below the threshold without exceeding the maximum execution time of rebalancing. If a request to write into a file which is being moved from a client takes place during a file moving step, the movement of the file is aborted and the file is deleted from the destination.

Method for rebalancing free disk space among network storages virtualized into a single file system view

A virtualizing file system view method for virtualizing one or more network storage devices into a virtualized file system view network storage system wherein destination network storage information of stored files is compactly held regardless of the number of files, and files are separated into one or more file groups and the file groups managed in destination network storage units. Until now, managing network storage unit information in individual files was necessary however the virtualizing file system view method reduces the management information that must be held and efficiently utilizes network storage capacity without holding destination network storage information in individual files. The cost of rewriting information is also lowered during structural changes such as adding or deleting network storage units since storage destination network information can be rewritten in file groups.
