Abstract
In a cluster system having two server apparatuses that operate as an in-use type or a standby type, a first server apparatus is provided with: a heartbeat transmission/reception part that transmits and receives heartbeat packets to and from a corresponding second server apparatus; and a corresponding node monitoring part that adjusts a timeout period for transitioning operation of the first server apparatus from a standby type to an in-use type, according to the reception state of the heartbeat packets.
Claims20
A first server apparatus in a cluster system having two server apparatuses that operate as an in-use type or a standby type, the first server apparatus comprising:
- a heartbeat transmission/reception part that transmits and receives a heartbeat packet to and from a corresponding second server apparatus;
- and
- a corresponding node monitoring part that adjusts a timeout period for transitioning operation of the first server apparatus from the standby type to the in-use type, according to a reception state of the heartbeat packet.
A cluster control method, comprising:
- transmitting or receiving, by a first server apparatus in a cluster system having two server apparatuses that operate as an in-use type or standby type, a heartbeat packet to or from a corresponding second server apparatus;
- and
- adjusting a timeout period for transitioning an operation of the first server apparatus from standby type to in-use type, according to a reception state of the heartbeat packet.
A non-transitory computer-readable storage medium storing a program that causes a computer provided in a first server apparatus in a cluster system having two server apparatuses that operate as an in-use type or standby type, to execute processings, the program comprising:
- transmitting or receiving a heartbeat packet to or from a corresponding second server apparatus;
- and
- adjusting a timeout period for transitioning an operation of the first server apparatus from a standby type to an in-use type, according to a reception state of the heartbeat packet.
