  • Patent number: 10235210
    Abstract: An operation management apparatus includes a storage unit and a processor. The storage unit stores therein operation scenario execution information including a first operation scenario and parallel execution information. The first operation scenario indicates an order of execution of a plurality of operation manipulations for a plurality of servers. The parallel execution information indicates whether the respective operation manipulations are to be executed in parallel with another operation manipulation. The processor acquires availability information indicating whether the respective servers are available. The processor generates execution determination information on basis of the operation scenario execution information when the availability information indicates existence of an unavailable server. The execution determination information indicates whether respective first operation manipulations are to be actually executed in execution of the first operation scenario.
