摘要： PROBLEM TO BE SOLVED: To provide a practical data warehouse using a network. SOLUTION: Data collection means 101 and 102 for forming and managing a replica of server data for clients 103 and 104 are connected to a network 113. The data collection means holds a data request condition given from a user through the clients, and negotiates with, for example, servers 114 and 122 for supplying data based on resources usable by the data collection means such as a storage device, a CPU or the like, whereby the data range and quality of the replica to be formed are adjusted. In query processing, queries from the clients are partially or entirely processed by use of a replica 123 formed within the data collection means. A query which is not processed by use of the replica is transferred to a server. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce the traffic of cache coherent commands outputted between nodes by invalidating data on the cache of another node in every page.
SOLUTION: A register 140 for instructing the invalidation of a page of a remote node is provided in each node of a main storage shared multiprocessor and all nodes are notified that writing is performed in the register 140. Further, a remote page invalidation circuit 150 issues a command for removing the whole cache lines belonging to a page of a node from a CPU cache of the node according to the notice received from other nodes. An ACK waiting circuit 160 notifies to the node of a request source that the invalidation of the page is finished after removing the whole cache lines. It is possible to realize to perform data writing without depending upon an instruction set of the CPU without performing transfer from the cache of another node.

摘要： PROBLEM TO BE SOLVED: To efficiently recognize operation conditions of a plurality of servers in an information system and manage caches without increasing manager's labor. SOLUTION: A plurality of servers 10 and 10 configure a multicast layer dynamically reconfigured by mutual support and communicate server states 109, cache directories 108, and validation by communication parts 106. Consequently, it is unnecessary for a manager to manage cooperation among servers except to designate and boot several servers. Not only caches are shared among servers by exchange of cache directories but also a validation time is reduced, whereby a quick user's reaction time can be obtained. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a flexible mounting method for a directory wherein a user can specify a mountable file or the like. SOLUTION: When a directory/x of a local file name tree is mounted on any of directory (c) of a common file name tree 2, information which a user specifies, such as mounting permission condition for indicating kinds of mountable file of the same name or the like, read-out operation information for controlling access operations, write operation information or an access authority table, is set in accordance with a mounting designation party (c). Access right is also set corresponding to a mounting source/x. Thus, selection of a file where mounting is allowed and execution of an access demand to a file (f) or (g) are controlled.
摘要翻译：要解决的问题：为用户可以指定可安装文件等的目录提供灵活的安装方法。解决方案：当本地文件名树的目录/ x安装在通用文件名树2的目录（c）中时，用户指定的信息，例如用于指示其可安装文件的种类的安装许可条件名称等，根据安装指定方（c）设置用于控制访问操作的读出操作信息，写入操作信息或访问权限表。访问权也对应于安装源/ x设置。因此，控制允许安装的文件的选择和对文件（f）或（g）的访问请求的执行。

摘要： PROBLEM TO BE SOLVED: To provide a practical data warehouse system, which attains, in a distributed environment, reduction in the load on a server and a network, reduction in storage device capacity on a client side, and reduction in update processing cost.
SOLUTION: A data collection means 101, 102 forming and managing a replica of server data for a client 103, 104 is connected to the network 113. The data collection means retains a data request condition given from a user through the client, and can adjust the data range and quality of the replica to be formed by negotiating with a server 114, 122 supplying data based on resources usable by the data collection means such as a storage or a CPU. In inquiry processing, a part or all of inquiries from the client is processed using the replica 123 formed within the data collection means. An inquiry which cannot be processed using the replica is transferred to the server.

摘要： PROBLEM TO BE SOLVED: To fast execute a series of remote procedure call between a client and a server. SOLUTION: An RPC optimizer 101 uses an IDL source code 103 and client source codes 102, 102'... as inputs. The optimizer 101 defines a series of remote procedure groups which are executed by a client to an additional server source code 107 as a new remote procedure and also outputs a new IDL source code 106 to which a remote procedure interface is added and the new client source codes 105, 105'... which are changed to use the remote procedures. Thus, a series of remote procedure groups to be executed by a client are collected together in a new remote procedure and accordingly plural times of remote procedures of communication is decreased down to once. As a result, the fast communication is possible between a client and a server.

摘要： PROBLEM TO BE SOLVED: To enable a user to make good use of the latest conversion destination file all the time without specifying a conversion source file and the timing of format conversion by holding the correspondence relation between the conversion source file and conversion destination files, and conversion programs in the file system. SOLUTION: In a conversion table 120, a group of the conversion source file 130 and conversion destination files 131, 131'... is made to correspond to the conversion programs 103, 103'... Then the correspondence relation between the conversion source file 130 and conversion destination files 131, 131'..., and the conversion programs 103, 103'... is held in the file system to eliminate the need to indicate which file is converted to which file by the user at each time. The operation that an application performs without fail when reading and writing a file is used as a trigger for format conversion. Consequently, the operation of the application is known in detail through the file system and corresponding operation can be done.

摘要： PROBLEM TO BE SOLVED: To select a communication line that performs fast communication and to shorten the time from sending a request to a client until the request is met by using the communication history of other server which has a possibility of having needed data and requesting a selected server to send the needed data from the other server. SOLUTION: When a client 204 sends a request 120 that includes a uniform resource locator(URL) to a server 205 and requests acquisition of URL content, a request processing part 101 retrieves a home page cache 104 returns the URL content with answerback to the client 204. Also, if the URL content does not exist in the cache 104, the server 205 refers to an access strategic table 105 which maintains a communication history, decides a server 205', 205",... to which the request should be sent and transfers a request 120 according to a request 122. The server 205 sends URL content that is acquired through an answer 123 from the server to which the request 120 is sent as answer 121 to the client 204.

摘要： PROBLEM TO BE SOLVED: To integrate not only the data stored in a relational database management system but also the data stored in data sources unable to efficiently execute an inquiry such as a legacy AP(application program) and a tertiary memory and to realize a high-speed inquiry. SOLUTION: A distributed index for the data source is generated in a database hub in advance, and a distributed index application section deforms and analyzes the query by using the distributed index. The high-speed inquiry is realized for the data stored in the data sources unable to efficiently execute the inquiry.
