Abstract

A method and apparatus for using a persistent message store in a distributed computing system. A message is stored in a persistent message store, wherein the message is a copy of an original message transmitted from a message producer to a message consumer in a distributed computing system. A command is received from a requestor to search the persistent message store for a stored message, the command indicating a search rule. The search rule is processed by a rules engine of the persistent message store to search for the stored message.

Claims

1. A computer implemented method, comprising:

storing a message in a persistent message store, wherein the message is a copy of an original message transmitted from a message producer to a message consumer in a distributed computing system;

receiving a command from a requestor to search the persistent message store for the stored message, the command indicating a search rule; and

processing the search rule by a rules engine of the persistent message store to search for the stored message.

2. The method of claim 1, further comprising:

receiving a new search rule from the requestor;

storing the new search rule;

assigning a rule identifier to the new search rule; and

communicating the rule identifier to the requestor.

3. The method of claim 2, further comprising:

receiving a search command that includes the rule identifier; and

processing the new search rule by the rules engine.

4. The method of claim 1, further comprising:

transmitting the message to the requestor if the message is found.

5. The method of claim 1, further comprising:

comparing search rules; and

if duplicate search rules are discovered, deleting the duplicate search rules.

6. The method of claim 1, wherein the command includes the search rule.

7. A machine-accessible storage medium including data that, when accessed by a machine, cause the machine to perform a method for a service oriented architecture, comprising:

storing a message in a persistent message store, wherein the message is a copy of an original message transmitted from a message producer to a message consumer in a distributed computing system;

receiving a command from a requester to search the persistent message store for a stored message, the command indicating a search rule; and

processing the search rule by a rules engine of the persistent message store to search for the stored message.

8. The machine-accessible storage medium of claim 7, the method further comprising:

receiving a new search rule from the requestor;

storing the new search rule;

assigning a rule identifier to the new search rule; and

communicating the rule identifier to the requester.

9. The machine-accessible storage medium of claim 8, the method further comprising:

receiving a search command that includes the rule identifier; and

processing the new search rule by the rules engine.

10. The machine-accessible storage medium of claim 7, the method further comprising:

transmitting the message to the requestor if the message is found.

11. The machine-accessible storage medium of claim 7, the method further comprising:

comparing search rules; and

if duplicate search rules are discovered, deleting the duplicate search rules.

12. The machine-accessible storage medium of claim 7, wherein the command includes the search rule.

13. An apparatus for a distributed computing architecture, comprising:

a router networked to a message producer and a message consumer, to intercept a message generated by the message producer, and to generate a copy of the message;

a persistent message store coupled with the router to store the copy of the message, and to receive a command from a requestor to search for the copy of the message, the command indicating a search rule, and

a rules engine coupled with the persistent message store to search for the copy of the message using the search rule.

14. The apparatus of claim 13, further comprising:

a message store manager coupled with the persistent message store to receive the command, the message store manager including the rules engine to search for the copy of the message in the persistent message store.

15. The apparatus of claim 14, further comprising:

the message store manager to receive a new search rule from the requester, to store the new search rule, to assign a rule identifier to the new search rule, and to communicate the rule identifier to the requestor.

16. The apparatus of claim 15, further comprising:

the message store manager to receive a search command that includes the rule identifier, and to process the new search rule by the rules engine.

17. The apparatus of claim 13, wherein the message store to transmit the copy of the message to the requestor if the copy of the message is found.

18. The apparatus of claim 13, further comprising:

a comparator to compare search rules, and, if duplicate search rules are discovered, to delete the duplicate search rules.

19. The apparatus of claim 13, wherein the command includes the search rule.
