Abstract

A system is provided for problem management for outsized queues. The system includes a computer readable storage medium comprising a management component stored as a set of computer instructions executable by a processor. The management component stops transmission of inbound messages for a queue managed by a first queue manager. The management component provides a copy of the queue to a second queue manager and recreates the queue as an empty queue for the first queue manager. The management component restarts the inbound messages for the recreated queue and enables the second queue manager to manage the copy of the queue. The management component enables an application that retrieved messages from the queue to retrieve messages from at least one of the recreated queue and the copy of the queue and to promote outputting data for a requesting user application to a user interface.

Claims

1. A system for problem management for outsized queues, comprising:

a computer readable storage medium comprising a management component stored as a set of computer instructions executable by a processor to;

stop transmission of inbound messages for a queue managed by a first queue manager prior to the queue becoming corrupted,

subsequently make and provide a copy of the queue to a second queue manager,

subsequently recreate the queue as an empty queue for the first queue manager,

subsequently restart the inbound messages for the recreated queue,

subsequently enable the second queue manager to manage the copy of the queue, and

subsequently enable an application that retrieved messages from the queue to retrieve messages from at least one of the recreated queue and the copy of the queue and to promote outputting data for a requesting user application to a user interface.

2. The system of claim 1, wherein the management component further detects a problem associated with a queue, wherein the problem is based on at least one of a size of the queue, a throughput issue associated with the queue, a memory usage associated with a processor that executes the first queue manager, a number of agent processes associated with the first queue manager, and a number of channel pool processes associated with the first queue manager.

3. The system of claim 1, wherein the queue is one of an inbound queue, an outbound queue, a local queue, and a transmission queue.

4. The system of claim 1, wherein the management component stops transmission of inbound messages for the queue on a periodic basis.

5. The system of claim 1, wherein the management component further:

determines whether the queue is corrupted, and

repairs the queue in response to a determination that the queue is corrupted.

6. The system of claim 1, wherein the management component further deletes the queue.

7. The system of claim 6, wherein the second queue manager is inactive prior to being enabled to manage the copy of the queue.

8. The system of claim 1, wherein the management component enables the second queue manager to manage the copy of the queue following a troubleshooting delay period.

9. The system of claim 1, wherein the management component further enables the application that retrieved messages from the queue to retrieve messages from the recreated queue instead of from the copy of the queue.

10. A computer implemented method for problem management for outsized queues,

comprising:

detecting a problem associated with a queue managed by a first queue manager;

subsequently stopping transmission of inbound messages for the queue;

subsequently stopping the first queue manager prior to the queue becoming corrupted;

subsequently making and providing a copy of the queue to a second queue manager;

subsequently restarting the first queue manager to recreate the queue as an empty queue for the first queue manager;

subsequently restarting the inbound messages for the recreated queue;

subsequently enabling the second queue manager to manage the copy of the queue; and

subsequently enabling an application that retrieved messages from the queue to retrieve messages from at least one of the recreated queue and the copy of the queue and to promote outputting data for a requesting user application to a user interface.

11. The computer implemented method of claim 10, wherein recreating the queue as the empty queue for the first queue manager is based on validating a log for the first queue manager.

12. The computer implemented method of claim 11, wherein validating the log for the first queue manager comprises determining queues that are needed for the first queue manager and identifying a deletion of the queue, wherein the queues that are needed for the first queue manager comprises the queue.

13. The computer implemented method of claim 10, wherein enabling the application that retrieved messages from the queue to retrieve messages from at least one of the recreated queue and the copy of the queue comprises restarting the application.

14. The computer implemented method of claim 10, wherein enabling the application that retrieved messages from the queue to retrieve messages from at least one of the recreated queue and the copy of the queue comprises enabling the application to at least one of read from and write to the at least one of the recreated queue and the copy of the queue.

15. A system for problem management for outsized queues, comprising:

a computer readable storage medium comprising a management component stored as a set of computer instructions sequentially executable by a processor to;

detect a problem associated with a queue managed by a first queue manager,

stop transmission of inbound messages for the queue prior to the queue becoming corrupted,

provide a copy of the queue to a second queue manager, recreate the queue as an empty queue for the first queue manager,

restart the inbound messages for the recreated queue,

enable the second queue manager to manage the copy of the queue,

identify a plurality of applications that retrieved messages from the queue,

identify at least one target application of the plurality of applications, and

enable the at least one target application to retrieve messages from the copy of the queue and to promote outputting data for a requesting user application to a user interface.

16. The system of claim 15, wherein the problem is associated with a plurality of queues managed by the first queue manager that comprise the queue.

17. The system of claim 16, wherein the management component further promotes the second queue manager managing the plurality of queues.

18. The system of claim 15, wherein the management component further enables the plurality of applications excluding the at least one target application to retrieve messages from the recreated queue.

19. The system of claim 18, wherein the management component further enables the plurality of applications excluding the at least one target application to retrieve messages from the copy of the queue.

20. The system of claim 15, wherein the management component further enables the at least one target application to retrieve messages from the recreated queue.
