Java virtual machine having integrated transaction management system
View Patent ↗A computing system comprises a plurality of computing nodes and is configured such that each computing node includes a processor configured to execute JAVA computer program instructions. The computing nodes cooperate to form a cluster, wherein the JAVA computer program instructions being executed by the plurality of computing nodes collectively accomplish a fully transactional application. Each application data object partition is associated with one of the computing nodes as a primary node for application data objects of that partition and further associated with at least one of the computing nodes as at least one secondary node for application data objects of that partition. Messages relative to an application data object are provided to the primary node for the application data object as well as to the at least one secondary node for that application data object, for updates. The particular application object is readable at any of the primary node and the at least one secondary node for that particular application data object.
