摘要： PROBLEM TO BE SOLVED: To provide an information access control environment by means of a third person having proper authority, while securing safety for the alteration and interception of data between systems executing communication. SOLUTION: A data storage part 106 transfers data between the communicating systems. A cryptographic key information storage part 105 is used for ciphering the data storage part 106 and is ciphered by using a user cryptographic key which has been previously shared between users. In a cryptographic key decoding information storage part 104, the third person having the proper authority, an information manager, for example, can decode data by the cryptographic key (b), and it is ciphered by using information manager cryptographic key which the information manager has previously designated. The cryptographic key information storage part 101 of access control information is used for ciphering an access control information storage part 102, and it is ciphered by using information manager cryptographic key of the third person having proper authority designated by the information manager, for example.

摘要： PROBLEM TO BE SOLVED: To easily connect a small-sized computer to the network of a different kind by providing a means for converting a frame relating to the network of the different kind to an 'Ethernet(R)' frame and the means for converting the 'Ethernet(R)' frame received from an 'Ethernet(R)' adapter to the frame relating to the network of the different kind. SOLUTION: When a scheduler 305 is activated, incoming and outgoing direction frame conversion tasks 302 and 304 search incoming and outgoing direction queues 306 and 307. As the result of searchinq, when it is judged that data are present, corresponding to the order of the queued data, a frame conversion processing for converting reception data stored in a control LAN side reception butter 308 from the frame for a control LAN to the 'Ethernet(R)' frame is performed. Also, the frame conversion processing for converting the reception data stored in an 'Ethernet(R)' side reception buffer 310 from the 'Ethernet(R)' frame to the frame for the control LAN as performed.

摘要： PURPOSE:To lighten the load of trace output processing by collecting the least trace information at the time of the start of operation, and collecting the trace information more detailed and of larger collected quantity than before in order to monitor the reoccurrence of the same fault at the time of the occurrence of the fault. CONSTITUTION:Trace control information 17 immediately after the start of the operation is of the loweset degree of detailedness. A trace collecting means 9 collects the trace information of the lowest degree of detailedness about all lines in conformity with the trace control information 17. At the time of the occurrence of the fault, a fault monitoring means 20 starts a trace control means 10. The trace control means 10 sets the degree of detailedness higher than before in the trace control information 17 in accordance with the fault. After the occurrence of the fault, the trace collecting means 9 collects the trace information of the higher degree of detailedness in conformity with the trace control information 17.

摘要： PURPOSE:To reduce the quantity of data to flow between information processors, and to lighten the burden of a communication line by information the completion of the transmission of a message at an upper level by using the confirmation of a response at the communication line level of a lower level without transmitting and receiving a response message between the upper levels. CONSTITUTION:A program to execute a request to send can set discrimination information at the upper level of a transmission message in the user data area 505 of a message control block mcb in a figure. Besides, the program to receive the completion of the transmission can acquire the discrimination information of transmission data which the program executed the request to send sets in the user data area 505. Accordingly, in respect of one message, the confirmation of the response at the communication level of the lower level can be used as the confirmation of the response of the upper level. Thus, the quantity of the data flowing between the information processors can be reduced, and the burden of the communication line can be reduced.

摘要： PURPOSE:To improve the program developability of a decentralized processing system by separating the attribute information related to an input-output message defined on a program when source programs are compiled and making the attribute information to correspond to the load module of a compiled result. CONSTITUTION:Programs 15001, 15002, and 15003 are assembled in the processor 15 of a developing system and each of the programs is actuated in accordance with an input from a CRT terminal 1501. The program 15001 generates load module files 3501-350n and an attribute file 3500 against a designated file of source program files. The program 15002 generates a loading message in accordance with the contents of the files 3501-350n and file 3500 and the program 15003 correlates the programs in accordance with the contents of the file 3500. Therefore, information necessary for loading the programs can be automatically generated and the relations among the programs can be recognized by only defining the information related to the input-output on a source program. Thus the soft developability of this system is improved.

摘要： PURPOSE:To automatically set a testing environment by designating optional programs to each developing-system processor and registering programs having an input/output relation with the programs in its own system as a test actuation possible form. CONSTITUTION:Processors 10, 20, 30-40 which are respectively connected with a network 1 having an optional form respectively develop programs A, B-E. Then the load modules 1,201, 1,202, 2,201, 3,201, and 4,201 of each program are stored in the disk 12, 22, 32, and 42 of each processor. The program E executes a message 601 having a content code CC1 and the program A executes processing on the message 601 as an input. As a result, the program A outputs a message 602 having a content code 2 and the programs B and C are actuated by means of the message 602. Moreover, the program D is actuated by the output message 603 of the program C.

摘要： PURPOSE:To identify all routes where test data flow by providing plural processors and making each processor accept its necessary data only. CONSTITUTION:An application program is developed by a soft developing device 11. Then the application program is added with the module identification codes and transmitted via a transmission line 1. The transmission controllers NCP1001-1006 and processors 11-16 are set in pairs on the line 1. The controllers NCP1001-1006 select only the necessary ones out of those data flowing through the line 1 and sends the selected data to the corresponding devices 12-16. These devices 12-16 are started at the time point when all data are ready and process data. These processing results are stored in a file 14000 or displayed on a CRT14001 of the device 11. The identification codes are added to the processing results stored in the file 14000 and therefore through which program the processing result is passed can be identified.

摘要： PURPOSE:To easily check file editing processing by switching the data input/ output subject of a program to a test file from an on-line file and adding the contents of an on-line copy file to transmit them to a network after the program is processed. CONSTITUTION:A means is provided to identify a specific file (on-line file) to which a program performs the input/output of data together with a means which copies the identified on-line file for production of both a test file and an on-line copy file. Furthermore a means which switches a file input/output processing subject of the program started a test to a test file is added to each processor together with a means which adds the contents of the on-line copy file and those of the test file and sends them to a network. Thus it is possible to check easily the file editing processing and to facilitate an on-line test.
