摘要： PURPOSE: To easily alter and to extend the decentralized processing system by eliminating the need to alter network constitution definition information that each computer has even when the constitution of the decentralized processing system is altered.
CONSTITUTION: The same message is reported firstly at a time to all computers 1 which constitute the decentralized processing system. Consequently, the resource control program 4-i of a computer 1-i receives a resource access request from an application program 6-i and searches a resource control ledger 5-i for information showing an object resource is present or not to return the information to the application program 6-i. When said resource is present, attribute information on the resource is taken out and reported to the application program 6-i to attain access. Further, the resource circuit program 4-i in a computer 1-i receives inquiry from the computer 1-i and performs similar processing. Consequently, only constitution definition information on the resource of the computer is required.

摘要： PROBLEM TO BE SOLVED: To provide a means for ensuring the restoration of the software of a former (present) version for the failure of the exchange of software from the present version to a new version in the maintenance of software. SOLUTION: A comparison execution means 132 is provided for a distribution destination computer in a state where the new version 113 and the former version 114 of software resource are stored in the prescribed storage area 131 of the distribution destination computer. The comparison execution means verifies identity between an execution module which is artificially generated from the software of the former version and an execution module (that is, the feasible form of the software of former version) which is previously registered before the exchange of software from the former version to the new version. When a verified result is satisfactory, a processing 133 for exchanging software to that of new version is executed. When the verified result is not satisfactory, the exchange processing 133 is stopped.

摘要： PROBLEM TO BE SOLVED: To improve the system throughput by avoiding waste of Endian conversion processing in a communication system comprising plural computers with various Endian forms. SOLUTION: A computer 110 (140) has an Endian information storage means 111 for other computers, a means 112 that discriminates an Endian form of an opposite computer and its own computer in the case of transmission, an Endian form revision means 121 that revises transmission data in matching with Endian of an opposite computer in the case of 1:1 communication and in matching with majority decision Endian at a receiver side in the case of 1:N communication, and an Endian information acquisition means 114 that sends/receives Endian information with other computer in the case of connection or the like. A conversion program by the means 121 and 112 acts like giving reception data to an application 113 without modification in the case of a start request from a 1:1 communication means 115. Conversion processing is conducted only when an Endian of the received data differs from that of its own computer in the case of a start request from a multi-cast/broadcast communication means 118.

摘要： PROBLEM TO BE SOLVED: To reduce the change processing of group constitution and to enable early detection concerning a remote procedure call(RPC) processing system for calling a group server. SOLUTION: When adding a server to a server group 80, an additional report is outputted from a group constitution change reporting part 70 to a processor provided with a server in the group such as a processor 5, for example. An RPC processing part 50, which receives this report, holds group constitution change information reporting the addition of new procedure. An RPC request source such as a client 15 of processor 2, for example, issues the RPC request of 'QSORT' to servers 25, 35 and 45 in the server group 80 and correspondent servers in the group are respectively executed. When executing a server 421 and transmitting the executed result to the request source, the processor 5 adds this group constitution change information. When any change in group constitution is detected out of a response message, an RPC processing part 10 at the request source updates its own address information by calling all the address information from an address managing part 60.

摘要： PROBLEM TO BE SOLVED: To perform the centralized management of nodes connecting plural subsystems. SOLUTION: Respective nodes 22, 331 and 332 transmit node survive signals storing their own states to a data field #3 periodically. A data field manager(DFM) 3(11) fetches the node survive signals transmitted to the data field #3 and transmits DF survive signals storing the states of respective nodes to the data field #3. A repeating node 1(12) does not repeat the node survive signals but repeats the DF survive signals. A system total manager (GM) 1 fetches the DF survive signals repeated from respective data fields to a data field #1, grasps the states of nodes in respective subsystems and displays these states.

摘要： PROBLEM TO BE SOLVED: To provide a multicast server device in which functional code filtering in the multicast server device and cell re-assembly in the server device can be attained, a delay time due to divided transmission can be shortened, and the device costs can be reduced. SOLUTION: In a computer control system in which plural hubs 3 with which plural computers 1 are connected are connected through an ATM transmission path 4, a multicast server device 2 connected with the hubs 3 is provided with a means for transferring the computer 1 and the information of functional codes necessitated by the computer, means for re-setting the connection of a point/multipoint at the time of registering the functional codes, and means for selecting multicast connections 61 and 62 to be transmitted from the functional codes in broadest data. When a cell including the functional codes is received, the selection processing of the multicast connection to be transmitted is started before the end of the re-assembly, and the cell re-assembly and the selection processing of the connection are executed in parallel.

摘要： PROBLEM TO BE SOLVED: To provide a means for sharing jobs with plural nodes and efficiently executing the jobs. SOLUTION: Plural kinds of job programs 210-212 corresponding to the contents of the jobs to be processed are executed by the plural nodes 101. Plural kinds of job patterns where the nodes being objects executing the self programs and priority for the respective nodes are defined are prepared for the respective job programs 210-212. Job pattern control data 230 defining the job pattern to be aborted in accordance with secular change is prepared. The job pattern is grasped by referring to job pattern control data 230, and the respective job programs 210-212 are executed by the node 101 obtained by referring priority.

摘要： PROBLEM TO BE SOLVED: To surely deliver TRAP generated at a node to be managed to a managing station in a network management or system management using SNMP. SOLUTION: MIB 75 for TRAP reception confirmation is defined and at the time of TRAP reception, a managing station 1 transmits a SET request so that the value of MIB for TRAP reception confirmation in response to the received TRAP can be set at a value expressing the completion of reception. After the TRAP is transmitted by a node 2a to be managed, the value of MIB for TRAP reception confirmation in response to the transmitted TRAP is monitored and when that value is not set to the value expressing the completion of reception even after the lapse of certain fixed time, the retransmitting processing of TRAP is performed.

摘要： PURPOSE:To obtain a management system in which it is not necessary for an operator to manage different kinds of node constitution information by automatically defining the different kinds of node constitution information necessary at the time of transmitting a request to the different kinds of node. CONSTITUTION:In a network system in which a managing station l manages different kinds of nodes 3 whose protocols are different through gate ways 2a and 2b, identifiers for specifying the different kinds of nodes 3 are automatically generated for each different kind of node by gate ways 2b and 2d at the time of request transmission, and stored as the different kind of node constitution information in which the identifiers are made to correspond to the addresses of the different kinds of nodes. Also, the managing station collects the different kind of node constitution information defined by each gate way from the gate ways, and stores it.
