In a method of controlling a computer system including a computer, the computer executes a virtualization program for causing logically divided resources of the computer to operate as first and second virtual computers, the first virtual computer executes a first OS, and the second virtual computer executes a second OS. In the method, information regarding the resources allocated to the first virtual computer and the second virtual computer by the virtualization program is obtained from the virtualization program, information indicating performance of the first virtual computer is obtained from the first OS, information indicating performance of the second virtual computer is obtained from the second OS, the obtained information and information indicating a time of obtainment of the information are stored in a storage system, and stored information is output.

Method of monitoring performance of virtual computer and apparatus using the method

One of a backup apparatus and a storage system performs control to store backup data in a storage system which belongs to an organization and/or location different from an organization and/or location to which a storage-target storage system for original data belongs, based on information (P) and/or (Q) below: (P) information relating to original data, and information relating to backup data, which is a copy of the original data; (Q) information indicating an organization and/or location to which each storage system belongs.

Computer system for controlling backups using wide area network

Policy verification arrangements effecting operations of: modifying address information of system component information for all system components, stored in a system management server, to redirect-address information to a test tool as a substitute destination in order for the test tool to be able to receive a result of system management operations during testing, instead of a corresponding system component; acquiring configuration information of the information processing system from the system management server; generating a test item specifying a test event; transmitting the test event specified by the generated test item to the policy manager and/or said system management server; and recording a result of the system management operations which is requested by the policy manager and/or system management server responsive to the test event specified by the generated test item, but which is redirected back to the test tool via the redirected-address information stored in the system management server.

Method and equipment for verifying propriety of system management policies to be used in a computer system

According to the invention, a managing server, using a snapshot-appended information table which stores management information for identifying snapshots of a virtual server, a setting change table which stores setting change information on the virtual server, and a policy table which stores policies to be met by the virtual server, acquires the setting change information from the setting change table, selects the setting change information items from the acquired setting change information matching policies stored in the policy table, acquires management information on the snapshots of the virtual server from the snapshot-appended information table, identifies a snapshot of the virtual server with reference to the acquired management information, changes the identified snapshot of the virtual server based on the selected setting change information items, and rolls back the virtual server according to the changed snapshot.

Remedying method for problems in virtual server system and system thereof

The following solution means are provided for easily specifying property items that have to be revised in order to satisfy a SLO (Service Level Objective): A storage unit () for storing an application SLO table that associates a standard SLO item defining a standard SLO with an application SLO item defining a SLO required for executing an application system, and a correspondence table that associates a standard SLO item with a property item having an impact on the standard SLO element. By specifying an application SLO item, a standard SLO item corresponding to that item is extracted from the application SLO table, and a property item corresponding to the extracted standard SLO item is acquired from the correspondence table.

Support apparatus, program, information processing system and support method

An absolute path name and a command line of a process associated with a process operating on a business server are found from process information acquired from the business server. A standard process decision unit judges an OS standard process. An interpreter decision unit judges an interpreter name from the command line. A shared directory decision unit judges an executive file name located directly under a shared directory. A subdirectory decision unit judges a parent-child relation of an executive file directory from the absolute path name of the executable file. As a result, an application name recognition unit recognizes a name of an application.

Configuration management server, name recognition method and name recognition program

A technique of performing concurrency control of policies is provided, which makes it possible to efficiently utilize resources of an overall information system. According to the present invention, a policy execution device creates a list of components of a application system which are influenced by execution of an action of a policy instance, for respective policy instances. If trigger conditions of another policy instance are newly met during execution of a policy instance, the policy execution device compares a list of components of the policy instance presently being executed with a list of components of the policy instance whose trigger conditions are newly met. If there are no common components in the lists, the policy execution device executes the policy instance whose trigger conditions are newly met, and if there are common components in the lists, the policy execution device suspends the policy instance whose trigger conditions are newly met.

Control device and control method for information system

A performance evaluating apparatus for a rule is provided, which is capable of evaluating a business value of a rule applied to the operation and management of an information system through autonomous control.

Performance evaluating apparatus, method, and computer-readable medium

A method for rapidly executing a series of remote procedure calls between a client and a server, comprising an RPC optimizer () that inputs an IDL source code () and client source codes (', . . . ) so as to define as a new remote procedure a group of remote procedures to be performed by the client in an additional server source code (). In turn, the RPC optimizer outputs a new IDL source code () to which an interface of the remote procedure is added, and new client source codes (&#x2032;, . . . ) modified so as to use the remote procedure. This reduces communications involving a plurality of remote procedures to a single communication pass, thereby implementing high-speed communication between the client and the server.
