Abstract

A method is provided for controlling whether transactions applied against a database go forward or are aborted on a transaction processing system. A tracking engine identifies an uncompleted transaction to be joined, joins the uncompleted transaction, and collects one or more attributes of the joined uncompleted transaction. The collected one or more attributes become available as a result of the joining of the uncompleted transaction. The collected one or more attributes of the joined uncompleted transaction are compared against rules in a rules engine to determine whether the joined uncompleted transaction goes forward or is aborted. Alternatively, the joined uncompleted transaction is automatically modified so that the collected attributes are in compliance with the rules in the rules engine, thereby allowing the joined uncompleted transaction to go forward and be applied against the database of the transaction processing system.

First claim

What is claimed is:

1. A method of controlling whether transactions applied against a database go forward or are aborted on a transaction processing system, the method comprising:
(a) using a tracking engine to:
(i) identify an uncompleted transaction to be joined, wherein the uncompleted transaction is a transaction that is being executed on behalf of an application or system utility, and wherein joining the uncompleted transaction makes the tracking engine a participant of the uncompleted transaction, wherein the tracking engine identifies the uncompleted transaction to be joined without requiring code modifications to the application or system utility, and without using an intercept library with the application or system utility,
(ii) join the uncompleted transaction, wherein joining the uncompleted transaction affects the outcome of the transaction, wherein the tracking engine joins the uncompleted transaction without requiring code modifications to the application or system utility, and
(iii) collect one or more attributes of the joined uncompleted transaction, wherein the collected one or more attributes became available as a result of the joining of the uncompleted transaction, and wherein the one or more attributes are related to the uncompleted transaction, and wherein the one or more attributes include one or more non-durable attributes, the one or more non-durable attributes being attributes that are not otherwise needed in order to complete a transaction,
wherein the tracking engine is a process independent from the application or system utility;

(b) comparing the collected one or more attributes of the joined uncompleted transaction against rules in a rules engine to determine whether the joined uncompleted transaction goes forward or is aborted; and
(c) the transaction processing system going forward with or aborting the uncompleted transaction based on the determination made in the comparing step (b),
wherein the uncompleted transaction in steps (a) and (b) is an audited transaction applied against a database that goes forward or is aborted on the transaction processing system.

2. The method of claim 1 wherein the one or more attributes of the joined uncompleted transaction include changes to the database.

3. The method of claim 1 wherein the one or more attributes of the joined uncompleted transaction include a time of day of the transaction.

4. The method of claim 1 wherein the one or more attributes of the joined uncompleted transaction include a user ID that started the transaction.

5. The method of claim 1 wherein the one or more attributes of the joined uncompleted transaction include a program identifier that participated in the transaction.

6. The method of claim 1 wherein the tracking engine joins the uncompleted transaction explicitly.

7. The method of claim 1 wherein the tracking engine joins the uncompleted transaction implicitly.

8. A method of applying transactions against a database on a transaction processing system, the method comprising:
(a) using a tracking engine to:
(i) identify an uncompleted transaction to be joined, wherein the uncompleted transaction is a transaction that is being executed on behalf of an application or system utility, and wherein joining the uncompleted transaction makes the tracking engine a participant of the uncompleted transaction, wherein the tracking engine identifies the uncompleted transaction to be joined without requiring code modifications to the application or system utility, and without using an intercept library with the application or system utility,
(ii) join the uncompleted transaction, wherein joining the uncompleted transaction affects the outcome of the transaction, wherein the tracking engine joins the uncompleted transaction without requiring code modifications to the application or system utility, and
(iii) collect one or more attributes of the joined uncompleted transaction, wherein the collected one or more attributes became available as a result of the joining of the uncompleted transaction, and wherein the one or more attributes are related to the uncompleted transaction, and wherein the one or more attributes include one or more non-durable attributes, the one or more non-durable attributes being attributes that are not otherwise needed in order to complete a transaction,
wherein the tracking engine is a process independent from the application or system utility;

(b) comparing the collected one or more attributes of the joined uncompleted transaction against rules in a rules engine to identify any attributes that violate a rule in the rules engine which prevents the joined uncompleted transaction from going forward;
(c) modifying the joined uncompleted transaction so that the attributes identified in step (b) are brought into compliance with the rules in the rules engine, thereby allowing the joined uncompleted transaction to go forward and be applied against the database of the transaction processing system; and
(d) the transaction processing system going forward with the modified uncompleted transaction and applying the transaction against the database,
wherein the uncompleted transaction is an audited transaction applied against the database in the transaction processing system.

9. The method of claim 8 wherein the modification in step (c) occurs automatically.

10. The method of claim 8 wherein the one or more attributes of the joined uncompleted transaction include changes to the database.

11. The method of claim 8 wherein the tracking engine joins the uncompleted transaction explicitly.

12. The method of claim 8 wherein the tracking engine joins the uncompleted transaction implicitly.

13. The method of claim 1 wherein the participant is a voting participant.

14. The method of claim 8 wherein the participant is a voting participant.
