Abstract

To enable use of an application on an application server at a mobile communication device, at a transaction server, a message received from the mobile is pushed out to the application. Any return messages is routed back to the mobile. The transaction server may use a queue to store all messages destined to a given application and attempt to push all messages on a given queue on receipt of a further message for the queue.

Claims

1. A method of enabling use of an application server application by a wireless communication device, the method comprising:

at a transaction server having two alternative modes of execution, the first mode being a clustered mode wherein the transaction server is scaled across multiple machines, the second mode being a non-clustered mode wherein the transaction server runs on a single machine;

on receipt of a given message from said wireless communication device for said application on said application server, queuing said given message on a queue for said application;

subsequent to said queuing, pushing said given message toward a destination for said application of said application server, wherein said pushing comprises dequeuing said message from said queue and pushing said message;

prior to said dequeuing and pushing, acquiring, via a locking mechanism, a lock for said destination on said application server, said lock preventing other use of said destination,

wherein if said transaction server is executing in said clustered mode, said locking mechanism comprises a lock object on one of said multiple machines, said one machine providing an interface to be used as a central lock provider by each of said multiple machines; and

wherein if said transaction server is executing in said non-clustered mode, said locking mechanism comprises a lock object that is local to the single machine on which said transaction server runs.

2. The method of claim 1 further comprising, after said dequeuing said message from said queue and pushing said message, releasing said lock for said destination on said application server.

3. The method of claim 1 wherein messages on said queue are queued on a first in first out (FIFO) basis and wherein a trailing message in said queue is not pushed until a message in said queue immediately preceding said trailing message is considered to have successfully reached said destination.

4. The method of claim 3 further comprising:

if a particular message pushed toward said destination does not successfully reach said destination, ceasing said dequeuing and pushing and re-queuing said particular message on said queue.

5. The method of claim 4 further comprising, on dequeuing said message and prior to pushing said message, logging said event and wherein said re-queuing said particular message comprises utilizing said log to identify messages to re-queue.

6. The method of claim 1 further comprising:

timing a retry interval and, on expiry of said retry interval, for each message on said queue;

dequeuing said each message from said queue and pushing said each message toward said destination for said application of said application server.

7. The method of claim 1 wherein said destination is a Component Object Model (COM) interface, a Distributed Component Object Model (DCOM) interface, a Simple Object Access Protocol (SOAP) interface, a .NET interface, or a .NETRemoting interface.

8. The method of claim 1 wherein said transaction server is executing in said clustered mode and wherein said acquiring of said lock comprises sending a lock request to said central lock provider.

9. A method of enabling use of an application server application by a wireless communication device, the method comprising:

at a transaction server operating in a clustered mode of execution wherein the transaction server is scaled across multiple machines;

on receipt of a given message from said wireless communication device for said application on said application server, queuing said given message on a queue for said application;

subsequent to said queuing, pushing said given message, and each message queued on said queue, toward a destination for said application of said application server, wherein said pushing comprises, for each message on said queue, dequeuing said each message from said queue and pushing said each message;

prior to said dequeuing and pushing, acquiring, via a locking mechanism, a lock for said destination on said application server, said lock preventing other use of said destination,

wherein said locking mechanism comprises a lock object on one of said multiple machines, said one machine providing an interface to be used as a central lock provider by each of said multiple machines.

10. The method of claim 9 further comprising, after said dequeuing said each message from said queue and pushing said each message, releasing said lock for said destination on said application server.

11. The method of claim 9 wherein messages on said queue are queued on a first in first out (FIFO) basis and wherein a trailing message in said queue is not pushed until a message in said queue immediately preceding said trailing message is considered to have successfully reached said destination.

12. The method of claim 11 further comprising:

if a particular message pushed toward said destination does not successfully reach said destination, ceasing said dequeuing and pushing and re-queuing said particular message on said queue.

13. The method of claim 12 further comprising, on dequeuing said each message and prior to pushing said each message, logging said event and wherein said re-queuing said particular message comprises utilizing said log to identify messages to re-queue.

14. The method of claim 9 further comprising:

timing a retry interval and, on expiry of said retry interval, for each message on said queue;

dequeuing said each message from said queue and pushing said each message toward said destination for said application of said application server.

15. The method of claim 9 wherein said destination is a Component Object Model (COM) interface, a Distributed Component Object Model (DCOM) interface, a Simple Object Access Protocol (SOAP) interface, a .NET interface, or a .NETRemoting interface.

16. The method of claim 9 wherein said acquiring of said lock comprises sending a lock request to said central lock provider.

17. A transaction server enabling use of at least one application server application by a wireless communication device, said transaction server having two alternative modes of execution, the first mode being a clustered mode wherein the transaction server is scaled across multiple machines, the second mode being a non-clustered mode wherein the transaction server runs on a single machine, the transaction server comprising:

a memory storing at least one queue, with one queue being provided for each of said at least one application on said application server;

a processor for, on receipt of a given message from said wireless communication device for a given application on said application server;

queuing said given message on a queue for said application;

subsequent to said queuing, pushing said given message toward a destination for said application of said application server, wherein said pushing by said processor comprises dequeuing said each message from said queue and pushing said each message;

prior to said dequeuing and pushing, acquiring, via a locking mechanism, a lock for said destination on said application server, said lock preventing other use of said destination,

wherein if said transaction server is executing in said clustered mode, said locking mechanism comprises a lock object on one of said multiple machines, said one machine providing an interface to be used as a central lock provider by each of said multiple machines; and

wherein if said transaction server is executing in said non-clustered mode, said locking mechanism comprises a lock object that is local to the single machine on which said transaction server runs.

18. The transaction server of claim 17 wherein messages on each of said at least one queue are queued on a first in first out basis and wherein said processor is for refraining from pushing a trailing message in said queue until said processor considers a message in said queue immediately preceding said trailing message has successfully reached said destination.

19. The transaction server of claim 18 wherein said processor is further for, if a given message pushed from said given queue toward said destination does not successfully reach said destination, ceasing said dequeuing and pushing and re-queuing said given message on said given queue.
