Abstract:
1. A computer-readable recording medium storing a computer program for causing a computer to function as a node which deletes or updates contents shared by a plurality of nodes mutually connected via a network, the computer program causing the computer to execute: transmitting a deletion or update instruction to cause the nodes owning the contents to delete or update the contents based on owning node information indicating owning nodes which own the contents; transmitting, to a responding node that sends back a response to the deletion or update instruction, non-responding node information indicating a non-responding node, if there is any non-responding node that does not respond to the deletion or update instruction; judging whether a ratio of a number of nodes from which the response is received to a number of nodes to which the instruction is transmitted is equal to or more than a given threshold; retransmitting the deletion or update instruction to the non-responding node after a given period passes when the ratio is judged to be less than the given threshold; and transmitting the non-responding node information when the ratio is judged to be equal to or more than the threshold.
