TASK SWITCHING METHOD, SERVER NODE AND CLUSTER SYSTEM

摘要

The present invention relates to the field of communications technologies and discloses a task switching method, a server node, and a cluster system. The task switching method includes the following steps: a first server node obtains an update timestamp of a second server node from a database; the first server node determines whether the second server node is failed according to update time in the update timestamp; and if the second server node is failed, the first server node updates a task bound with the second server node in the database to make the task be bound with an active server node and sends a definition of the task bound with the second server node to the active server node. With technical solutions of the present invention, a task bound with a failed server node can be executed on another active server node, which improves reliability of a cluster system.
