An instruction unit instructs a node as a movement source to move the queries during a period when the data to be processed by the queries to be moved is not distributed on the basis of the specified cycle. ## Claims ### Claim 1 A server device comprising: a memory; and a processor coupled to the memory, wherein the processor executes a process comprising: specifying cycle information including cycles and reference times of a plurality of queries, respectively, by detecting the cycles in which data is distributed via a network to a plurality of nodes that the plurality of queries are arranged, the data being distributed to one of the plurality of nodes that the data matches condition of a query arranged, the node being a server or a virtual machine operating on a server; classifying queries that corresponding data is distributed in a same specified cycle into groups based on the cycle information; and instructing, when a first group of queries is selected to move, a first node to move the first group of queries during a period in which corresponding data for the first group of queries is not distributed, wherein the specifying includes periodically specifying the cycle information. ### Claim 2 (depends on 1) The server device according to claim 1, wherein the process further comprises: selecting a query having a long period until data to be processed next is distributed as a movement target on the basis of the cycle information specified when a plurality of queries to be moved are present. ### Claim 3 A server device comprising: a memory; and a processor coupled to the memory, wherein the processor executes a process comprising: executing a processing of a query when data is distributed, the date being distributed to one of a plurality of nodes that the data matches condition of a query arranged, the nodes being a server or a virtual machine operating on a server; specifying cycle information including cycles and reference times of a plurality of queries, respectively, by detecting the cycles in which the data is distributed via a network to the plurality of nodes that the plurality of queries are arranged; classifying queries that corresponding data is distributed in a same specified cycle into groups based on the cycle information; receiving an instruction of moving a first group of queries; and moving, when the instruction of moving the first group of queries is received, the first group of queries during a period in which corresponding data for the first group of queries is not distributed, wherein the specifying includes periodically specifying the cycle information. ### Claim 4 A non-transitory computer-readable storage medium storing a movement control program causing a computer to perform: specifying cycle information including cycles and reference times of a plurality of queries, respectively, by detecting the cycles in which data is distributed via a network to a plurality of nodes that the plurality of queries are arranged, the data being distributed to one of the plurality of nodes that the data matches condition of a query arranged, the node being a server or a virtual machine operating on a server; classifying queries that corresponding data is distributed in a same specified cycle into groups based on the cycle information; and instructing, when a first group of queries is selected to move, a first node to move the first group of queries during a period in which corresponding data for the first group of queries is not distributed, wherein the specifying includes periodically specifying the cycle information. ### Claim 5 A movement control method for causing a computer to execute a process comprising: specifying, using a processor, cycle information including cycles and reference times of a plurality of queries, respectively, by detecting the cycles in which data is distributed via a network to a plurality of nodes that the plurality of queries are arranged, the data being distributed to one of the plurality of nodes that the data matches condition of a query arranged, the node being a server or a virtual machine operating on a server; classifying, using a processor, queries that corresponding data is distributed in a same specified cycle into groups based on the cycle information; and instructing, using a processor, when a first group of queries is selected to move, a first node to move the first group of queries during a period which corresponding data for the first group of queries is not distributed, wherein the specifying includes periodically specifying the cycle information. ### Claim 6 A server device comprising: a memory; and a processor coupled to the memory, wherein the processor executes a process comprising: specifying cycle information including cycles and reference times of a plurality of processing request sentences, respectively, by detecting the cycles in which data is distributed via a network to a plurality of nodes that the plurality of processing request sentences are arranged, the data being distributed to one of the plurality of nodes that the data matches condition of a processing request sentence arranged, the node being a server or a virtual machine operating on a server; classifying processing request sentences that corresponding data is distributed in a same specified cycle into groups based on the cycle information; and instructing, when a first group of processing request sentences is selected to move, to move the first group of processing request sentences during a period which corresponding data for the first group of processing request sentences is not distributed, wherein the specifying includes periodically specifying the cycle information. ### Claim 7 (depends on 1) The server device according to claim 1, wherein the classifying includes classifying queries that corresponding data is distributed in a same cycle that is periodically re-specified.
