Title: File replication system and file replication control method and storage medium
Inventor: SHINKAI YOSHITAKE
IPC: G06F12/00
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a file replication system in which the applicable range of file replication is increased by adding coherent guarantee control. SOLUTION: An IO request intercept means 2 requests a token control means 3 to permit access to a shared file 6 in response to an access request to the shared file 6.
