According to one embodiment, a program executing apparatus includes an event management portion to configure migration timing of the program on the basis of a state of the program being executed at reception of a migration request from the program, and a state transmission portion to migrate state information of the program on the basis of the migration timing configured in the event management portion.

Program executing apparatus and program execution method

Provided is a technology for improving the efficiency and the accuracy of data security. To this end, protection information provided to data is maintained correct even when it becomes necessary to change the necessity/non-necessity to protect the data depending on the content of a process performed on the data. More specifically, primitive data with protection attributes set thereon is read as the original data, and an operation is performed on the original data to generate derived data. Then, whether to make the derived data inherit the protection attributes of the original data is determined on the basis of a content of the operation performed on the original data.

Data management method

In a server-based computing environment, an environment that is the same as the environment realized on a server is provided to a user at a place where connection to a network can not be established. A virtual computer is constructed on the server. A client can executes an application program on the virtual computer. When the client is disconnected from the network, data required for constructing the virtual computer are saved in a file and that file is sent as it is to the client. On the client, the received file is used to construct the virtual computer, and work is continued on the virtual computer.

Computer system with a terminal that permits offline work

An object of this invention is to speed up file access and shorten the switching time upon failure. There is provided a computer system with plural storage systems and plural servers, in which: the storage systems each have a disk drive for storing files read/written by the servers and a storage control device, which has an interface connected to the servers via a network and a controller for controlling file read/write in the disk drive; the storage control device and the servers each have a cache memory, which temporarily stores files read/written by the servers, and a file cache control information unit, which keeps information of files stored in the cache memory; and the file cache control information unit holds information indicating whether or not a file is stored in the cache memory of the storage control device and/or the cache memories of the servers.

File cache-controllable computer system

An online application processing system capable of carrying out online application processing through the use of an easy-to-operate GUI environment takes advantage of the fact that the types of data exchanged by online application programs with a host terminal have conventionally been determined by the specifications of the terminal and are thus common to numerous online application programs. By matching data formats so that existing online application programs are used without modification, a GUI processing program is used as a host access program.
