  • Managing first and second handles used in communication with an apparatus connected to a network
    Patent number: 5995964
    Abstract: The number of openable file handles is limited by an OS. Simultaneously communicating partners are limited to, e.g., 64 systems. To solve this problem, a controller (202) of a communication control unit (201) assigns a virtual handle (Vj) in response to a request from a program (Pi) and manages a correspondence between a real handle (Rk) and the virtual handle (Vj) which is prepared by the OS. A program (Pn) of a group (H1) communicates with a program (P1') of a group (H2) using a real handle (R1) corresponding to a virtual handle (Vn). The controller 202 changes the correspondence between the real handle (Rk) and the virtual handle (Vj) to solve the shortage of the real handles (Rk).
