Abstract

A pooling mechanism to limit repeated connections in message queuing systems and to prevent excessive making and breaking of connections and associated overhead. The invention does this by providing a layer between a client and the message queuing system where connections are pooled. The pooling mechanism of the invention prevents a system from losing too many resources through the repeated making and breaking of excessive message queuing system connections.

Claims

1. A message queuing system having a message pooling layer between a client layer and a message queuing layer to provide a pool of reusable message queuing connections therebetween.

2. The message queuing system of claim 1 wherein said message pooling layer comprises a connection pool for containing reusable message queuing connections.

3. The message queuing system of claim 2 wherein said message pooling layer comprises a connection pool preserver running separate threads to maintain said connection pool.

4. The message queuing system of claim 1 wherein said message pooling layer comprises a message queue manager to receive requests for message queuing connections.

5. A message queuing system having a message pooling layer between a client layer and a message queuing layer to provide a pool of reusable message queuing connections therebetween, said message pooling layer comprising a connection pool for containing reusable message queuing connections, a pool preserver running separate threads to maintain said connection pool, and a message queue manager to receive requests for message queuing connections.

6. A program product comprising computer readable code on a media, said computer readable code adapted to configure and control a computer to establish a message pooling layer between a client layer and a message queuing layer to provide a pool of reusable message queuing connections therebetween.

7. The program product of claim 6 wherein said message pooling layer comprises a connection pool for containing reusable message queuing connections.

8. The program product of claim 7 wherein message pooling layer further comprises a pool preserver running separate threads to maintain said connection pool.

9. The program product of claim 6 wherein said message pooling layer further comprises a message queue manager to receive requests for said message queuing connections.

10. The program product of claim 6, wherein said program product is encrypted and requires decryption to configure and control a computer.

11. The program product of claim 6, wherein said program product is compressed and requires decompression to configure and control a computer.

12. The program product of claim 6 wherein said program product is on distribution media and requires installation to configure and control a computer.

13. A program product comprising computer readable code on a media, said computer readable code adapted to configure and control a computer to establish a message pooling layer between a client layer and a message queuing layer to provide a pool of reusable message queuing connections therebetween, said message pooling layer comprising a connection pool for containing reusable message queuing connections, a pool preserver running separate threads to maintain said connection pool, and a message queue manager to receive requests for said message queuing connections.

14. A method of queuing messages between a plurality of application programs running on one or more computers connected by a communications channel with at least one message queue, comprising the steps of:

a. creating reusable message queuing connections;

b. storing said message queuing connections in a connection pool; and

c. running threads to maintain said message queuing connections.

15. The message queuing method of claim 14 comprising storing reusable message queuing connections in the connection pool in a message pooling layer.

16. The message queuing method of claim 15 comprising running separate threads to maintain said connection pool, and wherein said message pooling layer comprises a connection pool preserver.

17. The message queuing method of claim 14 wherein said message pooling layer receives requests for message queuing connections.

18. A message queuing method having a message pooling layer between a client layer and a message queuing layer to provide a pool of reusable message queuing connections therebetween, said method comprising a connection pool in said message pooling layer containing reusable message queuing connections, running separate threads in a pool preserver to maintain said connection pool, and receiving request in a message queue manager for message queuing connections.
