ABSTRACT:
In an issue processing system for a right to use a resource in a data processing system having a global service program based on a fault-tolerant method providing a current processing server and a spare processing server, the resource management server includes: a re-transmission examination unit for examining a message from the processing server and determining whether it is a re-transmitted message based on a discriminator attached to the message for requesting acquirement of the right to use the resource; a discriminator addition unit for adding the discriminator to the message for requesting the right to use to be issued when that right to use is registered; and a right to use examination unit for examining whether the message is already registered based on a previous message for the re-transmission by referring to the discriminator attached by the discriminator addition unit when the message indicates the re-transmission message based on the detection of the re-transmission examination unit; wherein, when the examination unit judges that the right to use is already registered, the above registered right to use is invalidated, and a new right to use is registered into the nuclear program and the new right to sue is issued to the processing server.
