PURPOSE:To prevent a user control information file from generating a file access overhead by checking a bit of control information with an inter-space communication by a log-on control space when a user space is generated. CONSTITUTION:A log-on control space 12c that is generated in an IPL time, and on which a bit of user control information is loaded from a user control information file 4 has a capacity of almost 8MB, and it is constituted so that the bit of user control information of 1kB per one user is prepared,and users up to 8,000 can be contained. The load control space 12c performs the inter- space communication of the bit of user control information within the log-on control space 12c between spaces 12a and 12b, in the generation time of the space 12a and 12b, for the identification and the confirmation of users 1a and 1b, and for the confirmation of an access right for a computer system resource 3. At such a time, no access is performed to the user information control file 4 at all. In this way, a user control system in which no access overhead for the bit of user control information is generated can be obtained. |
