Abstract: The present invention achieves data relocation in accordance with a user's policies, in an environment where a plurality of storage devices coexist. The volumes belonging to storage devices A-D are managed virtually integrally. A host recognizes a plurality of storage devices A-D as a single virtual storage device. The user is able to group arbitrarily each volume belonging to the storage system, as a plurality of storage layers 1-3. For example, storage layer 1 can be defined as a high-reliability layer, storage layer 2, as a low-cost layer, and storage layer 3, as an archive layer. Each storage layer is constituted by a group of volumes corresponding to respective policies (high reliability, low cost, archiving). The user designates volumes V1 and V2 to be moved, in group units, and indicates a storage layer forming a movement destination, whereby the data is relocated.

Abstract: A job network setup method in a job management system which controls execution of jobs according to a set job network and which allows setup for data transfer from a preceding job to a succeeding job comprises enabling specifying such that data can be transferred from the preceding job to the succeeding job by linking a standard output of the preceding job to a standard input of the succeeding job when setting the succeeding job in setup of the job network.

Abstract: In the prior art, a user bore a heavy burden on operating together different products having the same functions. A user 102 calls a job net managing function 105 via GUI/CLI 103, and defines a job net 106. A job net execution controlling function 109 interrupts a definition of the job net 106, and sequentially executes the defined jobs. The defined jobs call not real commands directly, but switchers 110 to 114 that define regularized interfaces. The switchers, referring to environment variables 101, select adaptors 115 and 116 properly to call real commands 117 and 118 corresponding thereto.

Abstract: The disclosed is a method and system for storing a stencil for a job definition statement and data prescribing a user interface for job definition statement setup, generating data for executing a process for generating a job definition statement based on the contents set by a user via the user interface in accordance with the stencil for the job definition statement and the data prescribing the user interface for job definition statement setup, and generating a job definition statement by executing the process in accordance with the generated data.

Abstract: A computer has a table for managing a relationship between classes under which data to be processed unique to each of at least one first application program is classified according to a function/attribute thereof, and processes assigned to each class and each capable of being executed by a second application program. The table manages a relationship between said process and said second application program that executes said process. An in-context launching managing method comprises: when one of said data is selected, specifying the class to which said selected data belongs; extracting at least one process that is assigned to said specified class, creating a process list including the extracted process, and displaying said created process list; when one of said process is selected from said process list, accepting said selected process; and specifying the second application program related to said accepted process, and starting said specified second application program.

Abstract: The present invention achieves data relocation in accordance with a user's policies, in an environment where a plurality of storage devices are combined. The volumes belonging to storage devices A–D are managed virtually integrally. A host recognizes a plurality of storage devices A–D as a single virtual storage device. The user is able to group the volumes belonging to the storage system, as a plurality of storage layers 1–3. For example, storage layer 1 can be defined as a high-reliability layer, storage layer 2, as a low-cost layer, and storage layer 3, as an archive layer. Each storage layer is constituted by a group of volumes corresponding to respective policies (high reliability, low cost, archiving). The user designates volumes to be moved V1 and V2, in group units, and indicates a storage layer forming a movement destination, whereby the data is relocated.

Abstract: It is an object of the present invention to provide the function for displaying the configuration of storages not in a form peculiar to a storage system but in a more general purpose system. The present invention provides a method and system for displaying the configuration of a storage network, wherein each piece of apparatus constituting the storage network is connected to a control network different from the storage network connecting the pieces of apparatus to one another, and configuration information about each piece of apparatus is acquired using the control network, and a screen for displaying the configuration of the storage network is generated and displayed based on the acquired configuration information.

Abstract: To provide a technique to sort out a tangle of management procedures and management subjects and associate the two with each other. A computer system according to this invention includes: a storage system having plural disks and a disk array control unit; and a management device having a control unit that uses a jobnet to manage the storage system. In the computer system, the control unit obtains data corresponding to an identifier of a resource that is included in the jobnet, converts the jobnet into an executable format by rewriting and substituting the identifier with a display name or attribute of the resource, and registers an association between a jobnet identifier and a resource identifier in a database.

Abstract: A distributed file system in which the cache hit ratio of a client is enhanced to speed up a file access for each of users logging into the client. A file server includes an access frequency database in which the names of users are listed in association with the names of files that are frequently accessed by the individual users. Each client includes a log-in user table for entering the name of a user who is logging in, and a cache priority control module. The cache priority control module sets priority levels for the copies of the files stored in a cache area, on the basis of the contents of the access frequency database and the log-in user table. The set priority levels function as criteria when any of the file copies is to be expelled from the cache area. Owing to this construction, the copies of the files of high usage frequencies are preferentially kept in the cache area of the client for each user logging into this client, whereby the cache hit ratio can be enhanced to speed up the file access.

Abstract: A read/write replica of a file in a file server is updated through a communication line by a client. At the same time, a replica server detects the update data by using a virtual communication line between the client and a read-only replica of the file. The update data are used for refreshing the read-only replica. The refreshing process makes it unnecessary to send the update data from the file server to the replica server. Also, communication is made between the file server and the replica server to confirm validity of the update information taken in by the replica server to maintain equality of the files of the file server and the replica server. This can efficiently refresh the read-only replica of the replica server in a distributed data processing system without re-sending the update data.
