Abstract

A method for preferential reply routing, the method includes: receiving a request-reply message from a requesting application; detecting there is a preferred partition of a reply queue managed locally to an application server to which the requesting application is connected; qualifying a name of a reply queue stored in the request-reply message so that the name refers to the local partition that is managed locally to the application server; determining whether the local partition is available; wherein in the event the local partition is available: storing a reply message in the local partition; and retrieving the reply message from the local partition in response to the requesting application.

Claims

1. A method for preferential reply routing, wherein the method comprises:

receiving a request-reply message from a requesting application;

detecting there is a preferred partition of a reply queue managed locally to an application server to which the requesting application is connected;

qualifying a name of a reply queue stored in the request-reply message so that the name refers to the local partition that is managed locally to the application server;

determining whether the local partition is available;

wherein in the event the local partition is available;

storing a reply message in the local partition; and

retrieving the reply message from the local partition in response to the requesting application.

2. The method of claim 1, wherein in the event the local partition is unavailable:

routing the reply message to an alternate partition;

directing the requesting application to the alternate partition; and

retrieving the reply message from the alternate partition in response to the requesting application.

3. The method of claim 1, wherein the preferred partition is explicitly chosen by the requesting application.

4. The method of claim 1, wherein the preferred partition is implicitly selected by a messaging system that receives the request-reply message from the requesting application.

5. An article comprising one or more computer-readable storage media containing instructions that when executed by a computer enables preferential reply routing;

wherein the method further comprises;

receiving a request-reply message from a requesting application;

detecting there is a preferred partition of a reply queue managed locally to an application server to which the requesting application is connected;

qualifying a name of a reply queue stored in the request-reply message so that the name refers to the local partition that is managed locally to the application server;

determining whether the local partition is available;

wherein in the event the local partition is available;

storing a reply message in the local partition; and

retrieving the reply message from the local partition in response to the requesting application.

6. The article of claim 5, wherein in the event the local partition is unavailable:

routing the reply message to an alternate partition;

directing the requesting application to the alternate partition; and

retrieving the reply message from the alternate partition in response to the requesting application.

7. The article of claim 5, wherein the preferred partition is explicitly chosen by the requesting application.

8. The article of claim 5, wherein the preferred partition is implicitly selected by a messaging system that receives the request-reply message from the requesting application.

9. A system for preferential reply routing, the system comprising:

one or more server devices in communication with one or more client devices through a network;

wherein the one or more client devices are configured to allow an originating user to do the following;

compose a request-reply message with a requesting application on the one or more client devices;

send the request-reply message to the one or more servers; and

wherein the one or more server devices form a messaging system configured to do the following;

receive a request-reply message from a requesting application;

detect whether there is a preferred partition of a reply queue managed locally to an application server to which the requesting application is connected;

qualify a name of a reply queue stored in the request-reply message so that the name refers to the local partition that is managed locally to the application server;

determine whether the local partition is available;

wherein in the event the local partition is available;

a reply message is stored in the local partition; and

the reply message is retrieved from the local partition in response to the requesting application.

10. The system of claim 9, wherein in the event the local partition is unavailable the messaging system:

routes the reply message to an alternate partition;

directs the requesting application to the alternate partition; and

retrieves the reply message from the alternate partition in response to the requesting application.

11. The system of claim 9, wherein the preferred partition is explicitly chosen by the requesting application.

12. The system of claim 9, wherein the preferred partition is implicitly selected by the messaging system that receives the request-reply message from the requesting application.
