摘要： PURPOSE: To efficiently assign a work area by chaining assignable areas of each group in the ascending or descending order of address and retrieving and reassigning an assignable area meeting a request length for work area acquisition. CONSTITUTION: When a work area acquisition request is received, an empty area group of the chain of areas meeting the request length is determined, and the area meeting the request length is retrieved from the head of the chain, and it is disengaged from the chain when being found. The total length of used areas and that of empty areas are calculated and are stored in entries (A) 1a and (B) 1b. If the area meeting the request length is not found as the result of empty area group chain retrieval, chain retrieval is performed for a group of a chain of areas longer than the request length, and the area longer than the request length is disengaged from the chain when being found, and the area meeting the request length is obtained by division and is transferred to the request source. The empty area group to which the remaining area should be chained is determined to chain this area in a pertinent position.

摘要： PURPOSE:To transport a conventional application program interface to a system for handling only the data stream without changing the interface and to improve throughput by reducing the number of times of inputting to a magnetic disk. CONSTITUTION:At an electronic computer 13, an application program 11 and a block input program 12 are operated. A parameter 16 dispatched from the application program 11 is analyzed by the block input program 12, and data are simultaneously inputted from a magnetic disk 14. Thus, the application program interface can be transported to the system for handling only the data stream without being changed. Further, the throughput can be improved by reducing the number of times of I/O with the magnetic disk 14.

摘要： PROBLEM TO BE SOLVED: To provide a safe and simple management method of an open key certificate and a secret key by automating a system with a key management server which manages a key management table and an application management table. SOLUTION: When a connection request (1) to an application server 6 from a client terminal 4 is given, a key management server 1 obtains an open key certificate for application (4 and 5) from an application CA8, by using a key management table 2 (2) or an application management table 3 (3). An open key certificate for application and a secret key, which are required for certification at the time of connection with the application server 6, are transmitted to the client terminal 4 (6). The client terminal 4 is certified (7) at connection by using the open key certificate for application and the secret key, which are received from the key management server 1. If certification is successful, communication with the application server 6 can be conducted.

摘要： PROBLEM TO BE SOLVED: To reduce the overhead of search processing by performing the double step search of the search of a belonging group and a search inside a data group belonging to that group when searching data as an object out of data file information groups, which are simultaneously managed by a linear list type, existent in a cache memory pool. SOLUTION: Corresponding to a data access request 32 to a file, the search of the group to which the data of access object belong is processed as one step searches 33 and 34. Next, as two step searches, sequential searches 35, 36 and 3A are performed only to a linear list type cache buffer registered as the belonging group so that filed data existent on the cache buffer memory pool can be searched. When the data of access object do no exist on the cache buffer memory pool, such data are read from the file and registered on the cache buffer.

摘要： PURPOSE:To provide a failure recovery method which can shorten the failure recovery time in a system including many journal files and also can reduce the economical loss due to the discontinuation of system caused by a failure. CONSTITUTION:The journal files 31 and 32 are used as input files to carry out the 1st integration programs in parallel to each other, and the in-process files 41 and 42 are obtained together with the recovery information files 51 and 52. Then, the files 41 and 42 are used as input files to carry out the 1st integration programs, and an in-process file 4 and a recovery information file 5 are obtained. Finally the files 5, 51 and 52 are used as input files to carry out the 2nd integration programs, and an integration file is obtained. In such a constitution, the failure recovery time can be shortened in comparison with a method which integrates in sequence the updated journals out of all journal files.

摘要： PROBLEM TO BE SOLVED: To make it possible to authenticate validity of a received data in enciphered data communication using a self-decoding enciphering file. SOLUTION: A transmitter side generates electronic data authentication information 13 from an electronic data 10, and makes the information to be stored in a database 14. The transmitter side combines an enciphering file 17 obtained by using a password and enciphering the electronic data 10 with a receiver side decoding program 100 to generate a self-decoding enciphering file 21, and transmits it. A receiver side requests a password entry by a password input request program 18, and decodes the electronic data from the enciphering file 17 in the self-decoding enciphering file 21 by decoding program 19 using the password inputted. The receiver side generates electronic data authentication information 13A from the decoded electronic data by an electronic data authentication information generating program 20, and requests collation with the electronic data authentication information 13 stored in the database 14.
