Abstract

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.

Claims

1. A computing system comprising a plurality of computing nodes, the computing system configured such that:

each computing node includes a processor configured to execute computer program instructions in a platform independent language, wherein the computing nodes cooperate to form a cluster to support distributed transactional processing;

application objects are organized into partitions, wherein each partition is associated with one of the computing nodes as an active node for application data objects of that partition and further associated with at least one of the computing nodes as a replica node for application objects of that partition;

the computing nodes are configured such that messages relative to an application object are provided to the active node for the application object as well as to at least one replica node for that application object, for updates;

the computing system including a virtual machine integration layer integrating at least one Virtual Machine (VM) with a transaction processing platform that is transparent to the platform independent language;

wherein the computer program instructions executed by the cluster of computing nodes collectively accomplish a fully transactional distributed application executing on the at least one virtual machine.

2. The computing system of claim 1, wherein:

the computing nodes are configured such that the particular application object is readable at any of the active node and the at least one replica node for that particular application data object.

3. The computing system of claim 1, wherein the computing system is configured such that:

for the particular application object, all the nodes of the partition of that particular application object are configured to receive requests relating to the particular application object and to cause the requests to be routed to the active node for that particular application object.

4. The computing system of claim 3, wherein:

causing the requests to be routed to the active node for that particular data object is accomplished transparently.

5. The computing system of claim 3, wherein:

causing the requests to be routed to the active node for that particular application object is accomplished transparently for all application objects of the partition to which the particular data object belongs.

6. The computing system of claim 5, wherein:

transparent routing, for application objects of a partition, to a designated node.

7. The computing system of claim 1, wherein:

the replica node is a single one of the computing nodes.

8. The computing system of claim 1, wherein:

the system is configured to change the designated node to which to route requests to the replica node.

9. The computing system of claim 8, wherein:

the computing system is configured to change which node is the designated node based on the active node being unavailable.

10. The computing system of claim 9, wherein:

the computing system is further configured to restore a state of the application object from one of the at least one replica nodes based on the active node again becoming available.

11. The computing system of claim 1, wherein:

the computing system is configured to use an optimized implicit commit transactional protocol, wherein operations including creates, updates, and deletes for an application data object are transparently provided in a single request to the at least one replica node along with a commit for that operation and no transaction locks are taken on the at least one replica node as a result of such operations.

12. The system of claim 1, wherein the fully transactional application preserves atomicity, consistency, isolation, and durability properties of a transaction.

13. The system of claim 1, wherein the fully transactional application supports transactional locking, deadlock detection, and isolation.

14. The system of claim 1, wherein the system comprises service adaptors arranged to transparently accomplish user-defined business logic provided in the platform independent language in conjunction with generic transaction processing logic.

15. The system of claim 14, wherein transaction bindings are provided to support the user-defined business logic being executed by the at least one virtual machine employing the transaction processing features of the underlying transaction processing platform.

16. A computer program product comprising at least one tangible non-transitory computer readable medium having computer program instructions tangibly embodied thereon, the computer program instructions to configure a computing system comprising a plurality of computing nodes to:

configure each computing node to execute computer program instructions in a platform independent language, wherein the computing nodes cooperate to form a cluster to support distributed transactional processing, wherein the computer program instructions being executed by the plurality of computing nodes collectively accomplish a fully transactional application;

organize application objects into partitions, wherein each partition is associated with one of the computing nodes as an active node for application objects of that partition and further associated with at least one of the computing nodes as a replica node for application objects of that partition;
