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 computer program product for transaction processing in a hybrid EIS environment, the computer program product comprising:
one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
program instructions to receive, by a first computer of a distributed computing system, 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;
program instructions to generate, by the first computer, a unique identifier for the request; and
program instructions to send, by the first computer, 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 computer program product of claim 1 , the program instructions further comprising:
program instructions to maintain, by the first computer, a consistent state between the resources of the first computer and the resources of the second computer; and
program instructions for the transaction to be processed by the second computer.

3. The computer program product 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 computer program product of claim 1 , wherein the first computer is configured to host Java® based applications.

5. The computer program product of claim 1 , the program instructions further comprising:
program instructions for the first computer to send 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
program instructions for the second computer to send the unique identifier to the third computer.

6. The computer program product of claim 5 , the program instructions further comprising:
program instructions to respond to the reception, by the third computer, 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
program instructions for the third computer to treat the identified two separate physical connections as a single logical connection.

7. The computer program product of claim 6 , the program instructions further comprising:
program instructions for the first computer to send a signal to the third computer, wherein the signal is used to coordinate the processing of the transaction by second computer.

8. A computer system for transaction processing in a hybrid EIS environment, the computer system comprising:
one or more computer processors;
one or more computer readable storage media;
program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
program instructions to receive, by a first computer of a distributed computing system, 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;
program instructions to generate, by the first computer, a unique identifier for the request; and
program instructions to send, by the first computer, 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.

9. The computer system of claim 8 , the program instructions further comprising:
program instructions to maintain, by the first computer, a consistent state between the resources of the first computer and the resources of the second computer; and
program instructions for the transaction to be processed by the second computer.

10. The computer system of claim 8 , 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.

11. The computer system of claim 8 , wherein the first computer is configured to host Java® based applications.

12. The computer system of claim 8 , the program instructions further comprising:
program instructions for the first computer to send 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
program instructions for the second computer to send the unique identifier to the third computer.

13. The computer system of claim 12 , the program instructions further comprising:
program instructions to respond to the reception, by the third computer, 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;
program instructions for the third computer to treat the identified two separate physical connections as a single logical connection.

14. The computer system of claim 13 , the program instructions further comprising:
program instructions for the first computer to send a signal to the third computer, wherein the signal is used to coordinate the processing of the transaction by second computer.
