Abstract
The method determines whether a particular node of a high availability cluster is functioning properly or is a failed node. The method dumps node process state information as a dump data for the failed or crashed node in a shared storage area of the high availability cluster. A high availability cluster manager identifies the dump data that corresponds to the failed node as the most recent dump data for that failed node. The high availability cluster manager interrogates the dump data using kernel debugger services to identify a process trace and thereby identify the crash-causing application for the failed node. The method determines if the dump data includes a process match for the failed node process. The high availability cluster manager may initiate a crash-causing application notification to administrators or other entities of the high availability cluster. The method provides relocation and restoration capability of applications from the failed node to a fallover node and returns those application resources to the user and other entities using the high availability cluster.
