    摘要： Techniques are provided for managing a resource in a High Availability (HA) system. The techniques involve incrementing a count when a particular type of remedial action is performed on a resource, so that the count that reflects how often the particular type of remedial action has been performed for the resource. When it is determined that the resource has been in stable operation, the count is automatically reduced. After a failure, the count is used to determine whether to attempt to perform the particular type of remedial action on the resource. Examples of remedial actions include restarting the resource, and relocating the resource to another node of a cluster. By using the count, the system insures that a faulty resource does not get constantly “bounced”. By reducing the count when a resource has become stable, there is less likelihood that failure of otherwise stable resources will require manual intervention.

    摘要： A method and mechanism for failing over applications in a clustered computing system is provided. In an embodiment, the methodology is implemented by a high-availability failover mechanism. Upon detecting a failure of an application that is currently designated to be executing on a particular node of the system, the mechanism may attempt to failover the application onto a different node. The mechanism keeps track of a number of nodes on which a failover of the application is attempted. Then, based on one or more factors including the number of nodes on which a failover of the application is attempted, the mechanism may cease to attempt to failover the application onto a node of the system.
