摘要： [Problem]
It is possible to cope with a split-brain problem and a service stop failure in a high availability cluster configuration on a cloud.
[Solution]
In a case where an active system virtual server (server 310) detects stopping of a heartbeat received from a standby system virtual server (server 320), the active system virtual server notifies a coordination apparatus 100 of the detection of the stopping of a heartbeat. In addition, the active system virtual server reports whether or not a service is operating to the coordination apparatus. The coordination apparatus instructs the standby system virtual server to restart the system in a case where the stopping of a heartbeat and the operation of a service are received. The standby system virtual server restarts the service, restarts an operating system, or restarts the operating system in a case where the restart of the service is not successful, in response to an instruction for restarting the system.-

摘要： [Problem] It is determined whether quick repair handling is required for a failure in a communication apparatus or in a communication service that occurs in a nighttime period in compliance with an SLA while curbing operating expenses.
[Solution] A maintenance task management apparatus 11 determines handling of failures when both an apparatus failure that is a failure in communication apparatuses 46a and 46b in a nighttime period and a service failure that is a trouble in a communication service provided by the communication apparatuses 46a and 46b to users in the nighttime period occur or only the apparatus failure occurs. The maintenance task management apparatus 11 includes a handling determination unit 23 and a handling control unit 31. The handling determination unit 23 determines whether service interruption of communication due to double failures, which are both the apparatus failure and the service failure, violates an SLA that is service level agreement with users when the double failures are detected. The handling control unit 31 performs control for transmitting a quick handling notification for requesting quick failure repair to a worker terminal 42 when it is determined that the service interruption violates the SLA.-
