Abstract:
1. A non-transitory computer-readable recording medium storing a software update command program that causes a computer connected to a plurality of service provider nodes in a cluster system over a network to transmit an update command of a service provider program with respect to the service provider nodes, the software update command program causing the computer to execute: transmitting a program information about the service provider program being executed by the computer, at predetermined transmission interval, to a monitoring node that monitors the cluster system; receiving a node list information including the program information of the service provider nodes from the monitoring node; selecting an update target which of the service provider nodes are not yet updated with the service provider program by referring to the program information in the node list information, and selecting, as the update target service provider node, at least one of the service provider nodes not yet updated with the service provider program; determining a command timing in response to an input of first update timing information together with the update command with respect to the service provider program being executed by the computer, wherein a time after a lapse of a standby time found in the first update timing information is set as the command timing of the update command where the first update timing information indicating the standby time until the update command is transferred; generating a second update timing information indicating a standby time until the update command is transferred from the update target service provider node to any of the other of the service provider nodes; and command-transmitting an update command, when the command timing comes, transmitting the update command of the service provider program and the second update timing information to the update target service provider node.
