Abstract
A file control device receives access requests from an application requesting the exclusion of file resources and an application requesting no such exclusion through a network and also accepts an access request from an application inside the device. Exclusive control over the file resources is automatically performed among the access requests.
Claims9
A file control device connected to a network having a first access source requesting exclusion of a file resource and a second access source requesting no exclusion of the file resource, for handling access requests for the file resource, the file control device comprising:
- an interface device receiving an access request from the first access source and an access request from the second access source through the network;
- a request reception device accepting the access request from the first access source, the access request from the second access source and an access request from a third access source in the file control device;
- a registration device registering the accepted access requests;
- and
- a control device performing exclusive control over the file resource among the access requests from the first, second, third access sources in response to the access request from the second access source.
The file control device according to claim 6, wherein
- when the access request from the second access source corresponds to a process for which exclusion release of the file resource is required, said control device performs an exclusion release request process for the file resource.
The file control device according to claim 6, wherein
- when there is no access request from the second access source for a specific time period after exclusion of the file resource is secured in response to the access request from the second access source, said control device compulsorily releases the exclusion of the file resource.
A computer-readable storage medium on which is recorded a program enabling a computer connected to a network having a first access source requesting exclusion of a file resource and a second access source requesting no exclusion of the file resource, for handling access requests for the file resource, to perform a process, the process comprising:
- receiving an access request from the first access source and an access request from the second access source through the network;
- accepting the access request from the first access source, the access request from the second access source and an access request from a third access source in the file control device;
- registering the accepted access requests;
- and
- performing exclusive control over the file resource between the access requests from the first, second and third access sources in response to the access request from the second access source.
A propagation signal for propagating a program enabling a computer connected to a network having a first access source requesting exclusion of a file resource and a second access source requesting no exclusion of the file resource, for handling access requests for the file resource, to perform a process, the process comprising:
- receiving an access request from the first access source and an access request from the second access source through the network;
- accepting the access request from the first access source, the access request from the second access source and an access request from a third access source in the file control device;
- registering the accepted access requests;
- and
- performing exclusive control over the file resource between the access requests from the first, second and third access sources in response to the access request from the second access source.
A file control method used in a shared system connected to a network having a first access source requesting exclusion of a file resource and a second access source requesting no exclusion of the file resource, for handling access requests for the file resource, the file control method comprising:
- receiving an access request from the first access source and an access request from the second access source through the network;
- accepting the access request from the first access source, the access request from the second access source and an access request from a third access source in the file control device;
- registering the accepted access requests;
- and
- performing exclusive control over the file resource between the access requests from the first, second and third access sources in response to the access request from the second access source.
A file control device connected to a network having a first access source requesting exclusion of a file resource and a second access source requesting no exclusion of the file resource, for handling access requests for the file resource, the file control device comprising:
- interface means for receiving an access request from the first access source and an access request from the second access source through the network;
- request reception means accepting the access request from the first access source, the access request from the second access source and an access request from a third access source in the file control device;
- registration means for registering the accepted access requests;
- and
- control means for performing exclusive control over the file resource between the access requests from the first, second and third access sources in response to the access request from the second access source.
