Abstract: An embodiment of the invention is a technique to detect data corruption of critical data structures and to repair the corrupted critical data structures. Information data of critical data structures used by a managing module are captured upon initialization of the managing module. The captured information data are considered valid, and stored in a data vault. Critical data structures used by the managing module are monitored for validity during operation of the managing module. A corruption of a critical data structure corresponding to a stored data of the stored captured information data is detected during operation of the managing module. The corrupted data structure is restored to an operational state by using the corresponding stored data in the data vault without interrupting the operation of the managing module.

Abstract: An embodiment of the invention is a method for modeling a reflexive inverse relationship in a computer system. A general association representing the reflexive inverse relationship is created. The general association has a named end and an unnamed end. A specific association having the general association as a generalization is created. The specific association has a first specific end and a second specific end. The first specific end is used to redefine the named end of the general association. The second specific end is also used to redefine the named end of the general association.

Abstract: An embodiment of the invention is a method for proactive failover using user-defined rules. An event log of a first server node is monitored to check for user-specified application events. One of the user-specified application events corresponding to an impending failure in an application running on a first server node is detected. In automatic response to the detected impending failure, a proactive failover process is executed to transfer the application to a second server node for continued execution, the second server node being connected to the first server node in a cluster.
