Abstract
Database server instances in a database server cluster broadcast, to other instances in the cluster, information concerning certain problem events. Because each server instance is aware of problems that other server instances are experiencing, each server instance is enabled to make more intelligent decisions regarding the actions that it should perform in response to the problems that the server instance is experiencing. Instead of terminating itself, a server instance might opt to wait for a longer amount of time for an operation to complete. The server instance may do so due to the server instance having received information that indicates that other server instances are experiencing similar problems. Whenever the information received from other server instances makes it appear that a problem is unlikely to be solved in the cluster as a whole by terminating a server instance, that server instance may continue to wait instead of terminating itself.
