Abstract

One or more policies to be applied to a set of one or more messages in a message oriented middleware are defined. Metrics of the message oriented middleware are monitored. Application of a policy in response to a trigger condition being satisfied is initiated. Application of the policy applies actions across the set of one or more messages.

Claims

1. A method for application of system level policy in message oriented middleware, comprising:

defining one or more policies to be applied to a set of one or more messages in the message oriented middleware;

monitoring metrics of the message oriented middleware;

initiating application of a policy in response to a trigger condition being satisfied; and

where application of the policy applies actions across the set of one or more messages.

2. The method of claim 1, where defining the one or more policies to be applied to the set of one or more messages in the message oriented middleware comprises defining one or more quality of service (QoS) policies.

3. The method of claim 1, where defining the one or more policies to be applied to the set of one or more messages in the message oriented middleware comprises defining one or more trigger conditions for activating the one or more policies, defining one or more actions to be applied, and linking the one or more trigger conditions to the one or more actions.

4. The method of claim 1, where application of the policy applies actions at selected points in the message oriented middleware comprising at least one of:

at messages stored on a queue, at durable or non-durable subscription to messages, at transmission streams between components in a distributed messaging system, message buffers, and a group of the above points.

5. The method of claim 1, where defining the one or more policies to be applied to the set of one or more messages in the message oriented architecture comprises defining at least one policy that modifies a quality of service (QoS) of at least one of the set of one or more messages after the at least one of the set of one or more messages is stored in response to the trigger condition being satisfied.

6. The method of claim 1, where application of the policy applies system level mediation to the set of one or more messages.

7. The method of claim 1, where application of the policy applies the actions to an abstract representation of at least one message to allow manipulation of the at least one message without loading the whole at least one message into memory.

8. The method of claim 7, where the abstract representation of the at least one message allows only loading of metadata of the at least one message.

9. The method of claim 1, where application of the policy is provided by access to metadata about a point of queuing of at least one message within a queue and an ability to modify behavior of the queue.

10. The method of claim 1, where monitoring the metrics of the message oriented middleware comprises monitoring internal and external metrics of the message oriented middleware.

11. A computer program product for application of system level policy in message oriented middleware comprising a computer-readable storage medium in which computer-executable instructions are stored, which instructions, when executed by a computer, cause the computer to:

define one or more policies to be applied to a set of one or more messages in the message oriented middleware;

monitor metrics of the message oriented middleware;

initiate application of a policy in response to a trigger condition being satisfied; and

where application of the policy applies actions across the set of one or more messages.

12. A system for application of system level policy in message oriented middleware, comprising:

a messaging server;

a monitoring component that monitors metrics of the message oriented middleware;

a determining component that initiates application of a defined policy in response to a trigger condition being satisfied; and

where application of the defined policy applies actions across a set of one or more messages.

13. The system of claim 12, where the defined policy defines a quality of service (QoS) policy.

14. The system of claim 12, where the defined policy comprises one or more trigger conditions for activating the defined policy, one or more actions to be applied, and a link between the one or more trigger conditions and the one or more actions.

15. The system of claim 12, where the determining component applies actions at selected points in the message oriented middleware comprising at least one of:

at messages stored on a queue, at durable or non-durable subscription to messages, at transmission streams between components in a distributed messaging system, message buffers, and a group of the above points.

16. The system of claim 12, where the defined policy modifies a quality of service (QoS) of at least one of the set of one or more messages after the at least one of the set of one or more messages is stored in response to the trigger condition being satisfied.

17. The system of claim 12, where the determining component applies system level mediation to the set of one or more messages.

18. The system of claim 12, where the determining component applies the defined policy to an abstract representation of at least one message to allow manipulation of the at least one message without loading the whole at least one message into memory.

19. The system of claim 18, wherein the abstract representation of the at least one message allows only loading of metadata of the at least one message.

20. The system of claim 12, where the determining component applies the defined policy by access to metadata about a point of queuing of at least one message within a queue and an ability to modify behavior of the queue.

21. The system of claim 12, where the monitoring component monitors metrics of the message oriented middleware comprising internal and external metrics.
