Abstract

The present disclosure describes methods, systems, and computer program products for correlating messages. The method can include identifying a message received at an end point associated with executing business process instances. Attributes of the message are identified. The message can be associated with a defined set of relevant attributes associated with a correlation condition of business process instances associated with the end point. A message context fingerprint hash calculated using the attributes of the identified message is generated. The message context fingerprint hash is uniquely associated with the identified message and compared to a number of business process instance fingerprint hashes. The business process instance fingerprint hashes can be generated from a number of business process instance associated with the end point. The identified message associated with the message context fingerprint hash can be correlated with the business process instance associated with the matching hashed business process instance fingerprint hash.

Claims

1. A computer-implemented method for managing system alert incidents, comprising:

identifying a message received at an end point associated with at least one executing business process instance;

identifying at least one attribute of the identified message associated with a defined set of relevant attributes associated with a correlation condition of at least one business process instance associated with the end point;

generating a message context fingerprint containing the at least one identified attribute of the identified message;

applying a hash algorithm to the message context fingerprint to create a message context fingerprint hash, the message context fingerprint hash uniquely associated with the at least one identified attribute of the identified message;

comparing the message context fingerprint hash to a plurality of business process instance fingerprint hashes of a corresponding plurality of business process instances associated with the end point; and

correlating the identified message associated with the message context fingerprint hash with the business process instance associated with the matching hashed business process instance fingerprint hash.

2. The computer-implemented method of claim 1, further comprising sending the message to the corresponding business process instance for consumption.

3. The computer-implemented method of claim 1, further comprising:

receiving the message at a corresponding business process instance;

in response to a determination that the control flow of the corresponding business process instance is ready to consume the message, comparing the message context fingerprint hash of the message to the current business process instance fingerprint hash of the corresponding business process instance to confirm a match; and

consuming, in response to a determination that a match is confirmed, the message at the corresponding business process instance.

4. The computer-implemented method of claim 3, further comprising discarding the message in response to a determination that a match is not confirmed.

5. The computer-implemented method of claim 1, wherein the end point comprises a structure defined by an intermediate message event associated with a process definition.

6. The computer-implemented method of claim 2, wherein the payload of the received message is provided in an XML schema or web service description language.

7. The computer-implemented method of claim 1, wherein the correlation condition comprises equality conditions concatenated with a logical operator based on payload and context of the message.

8. The computer-implemented method of claim 1, wherein the defined set of relevant attributes are defined by rules for extracting data from the context of the received message.

9. The computer-implemented method of claim 1, further comprising initiating at least one business process instance, wherein the at least one business process provides input data used in the context of the message.

10. The computer-implemented method of claim 1, wherein the plurality of business process instance fingerprint hashes are generated into a predetermined format based at least on position, type, and value.

11. The computer-implemented method of claim 1, wherein at least one of the business process instance fingerprint hashes is defined upon instantiation of the at least one business process instance.

12. The computer-implemented method of claim 1, wherein at least one of the business process instance fingerprint hashes is recalculated during execution of the at least one business process instance in response to a change to a process context associated with the at least one business process instance.

13. A tangible, non-transitory computer-readable medium encoded with a computer program, the program comprising instructions that when executed by one or more computers cause the one or more computers to perform operations for correlating messages comprising:

identifying a message received at an end point associated with at least one executing business process instance;

identifying at least one attribute of the identified message associated with a defined set of relevant attributes associated with a correlation condition of at least one business process instance associated with the end point;

generating a message context fingerprint containing the at least one identified attribute of the identified message;

applying a hash algorithm to the message context fingerprint to create a message context fingerprint hash, the message context fingerprint hash uniquely associated with the at least one identified attribute of the identified message;

comparing the message context fingerprint hash to a plurality of business process instance fingerprint hashes of a corresponding plurality of business process instances associated with the end point; and

correlating the identified message associated with the message context fingerprint hash with the business process instance associated with the matching hashed business process instance fingerprint hash.

14. The computer-readable medium of claim 13, further comprising instructions that when executed by one or more computers cause the one or more computers to perform operations for correlating messages comprising sending the message to the corresponding business process instance for consumption.

15. The computer-readable medium of claim 13, further comprising instructions that when executed by one or more computers cause the one or more computers to perform operations for correlating messages comprising:

receiving the message at a corresponding business process instance;

in response to a determination that the control flow of the corresponding business process instance is ready to consume the message, comparing the message context fingerprint hash of the message to the current business process instance fingerprint hash of the corresponding business process instance to confirm a match; and

consuming, in response to a determination that a match is confirmed, the message at the corresponding business process instance.

16. The computer-readable medium of claim 15, further comprising instructions that when executed by one or more computers cause the one or more computers to perform operations for correlating messages comprising discarding the message in response to a determination that a match is not confirmed.

17. A system of one or more computers configured to perform operations for correlating messages comprising:

identifying a message received at an end point associated with at least one executing business process instance;

identifying at least one attribute of the identified message associated with a defined set of relevant attributes associated with a correlation condition of at least one business process instance associated with the end point;

generating a message context fingerprint containing the at least one identified attribute of the identified message;

applying a hash algorithm to the message context fingerprint to create a message context fingerprint hash, the message context fingerprint hash uniquely associated with the at least one identified attribute of the identified message;

comparing the message context fingerprint hash to a plurality of business process instance fingerprint hashes of a corresponding plurality of business process instances associated with the end point; and

correlating the identified message associated with the message context fingerprint hash with the business process instance associated with the matching hashed business process instance fingerprint hash.
