Abstract:
A method for providing a first Java Virtual Machine (â€œJVMâ€ ) with mechanisms to support fault-tolerant operation, comprising the steps of:(a) modifying the first JVM to use information maintained by the first JVM to identify objects that are created, modified, and/or discarded during a process of responding to an event of a transaction, such objects that are created, modified, and/or discarded during a process of responding to an event of a transaction defining at least a portion of a checkpoint; (b) delivering to at least one second JVM the at least a portion of a checkpoint; and (c) storing in the at least one second JVM the at least a portion of a checkpoint for use by the at least one second JVM in the processing of subsequent events of the transaction.
