Abstract

A first computer of a distributed computing system receives a request for a transaction. The transaction is an eXtended Architecture (XA) protocol based global transaction. The first computer generates a unique identifier for the request. The first computer sends the unique identifier to a second computer of the distributed computing system. The unique identifier enables the second computer to participate with the first computer as an XA protocol based resource participant.

First claim

What is claimed is:

1. A method of transaction processing in a hybrid EIS environment, the method comprising:
a first computer of a distributed computing system, receiving a request for a transaction, wherein the transaction is an eXtended Architecture (XA) protocol based global transaction, wherein the first computer implements one or both of a complete XA protocol and a JCA based transaction contract;
the first computer generating a unique identifier for the request; and
the first computer sending the unique identifier to a second computer of the distributed computing system, wherein the second computer is, at most, partially XA compliant, the unique identifier enabling the second computer to participate as an XA protocol based resource participant with the first computer such that at least some of the computing resources of both the first computer and the second computer are used in conjunction to execute the logic needed to process the XA protocol based global transaction.

2. The method of claim 1 , the method further comprising:
the first computer maintaining a consistent state between the resources of the first computer and the resources of the second computer; and
the second computer processing the transaction.

3. The method of claim 1 , wherein the second computer is an Enterprise Information System (EIS), and wherein reception of the unique identifier by the second computer enables the second computer to participate as an XA protocol based resource participant that implements at least one of a complete XA protocol or a JCA based transaction contract.

4. The method of claim 1 , wherein the first computer is configured to host Java® based applications.

5. The method of claim 1 , the method further comprising:
the first computer sending the unique identifier to a third computer of the distributed computing system that is configured to be a resource manager of the second computer and the first computer; and
the second computer sending the unique identifier to the third computer.

6. The method of claim 5 , the method further comprising:
the third computer responding to the reception of the unique identifier from the first computer and the second computer by identifying two separate physical connections that respectively correspond to the first computer and the second computer; and
the third computer treating the identified two separate physical connections as a single logical connection.

7. The method of claim 6 , the method further comprising:
the first computer sending a signal to the third computer, wherein the signal is used to coordinate the processing of the transaction by second computer.
