Abstract

In accordance with an embodiment, described herein is a system and method for dynamic debugging in an application server environment. An exemplary method can provide, at one or more computers, including an application server environment executing thereon, a plurality of deployable resources which can be used within the application server environment, one or more running managed servers, the one or more managed servers being within a domain, and a debug framework, the debug framework comprising a debug patch directory, the debug patch directory containing one or more debug patches. The method can activate a selected debug patch within the domain, the selected debug patch comprising at least one class, the selected debug patch designed to gather information about the problem within the domain. The managed servers, upon activation of the selected debug patch, can remain running. The method can also deactivate the selected debug patch without requiring a restart.

Claims

1. A system for dynamic debugging in an application server environment, comprising:

one or more computers, including an application server environment executing thereon, together with

a plurality of deployable resources which can be used within the application server environment,

one or more running managed servers, the one or more managed servers being within a domain, and

a debug framework, the debug framework comprising a debug patch directory, the debug patch directory containing one or more debug patches;

wherein the system is configured to, upon an indication of a problem within the domain, activate a selected one of the one or more debug patches within the domain, the selected one of the one or more debug patches comprising at least one class, the selected one of the one or more debug patches designed to gather information about the problem within the domain; and

wherein upon activation of the selected one of the one or more debug patches within the domain, the one or more running managed servers are not restarted.

2. The system of claim 1, wherein the selected one of the one or more debug patches, upon activation within the domain, replaces at least one class within the domain, the at least one class of the debug patch having a same shape as at least one class within the domain.

3. The system of claim 1, wherein the system is further designed to log the gathered information about the problem within a log, the log being accessible by a system administrator.

4. The system of claim 2, wherein the system is further configured to, after activation of the selected one of the one or more debug patches within the domain, deactivate the selected one of the one or more debug patches without restarting the one or more running managed servers.

5. The system of claim 1, wherein the application server environment comprises a multi-tenant application server environment, and wherein the system further comprises one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, that can be associated with a tenant.

6. The system of claim 5, wherein the activated selected one of the one or more debug patches within the domain is scoped to a partition of the one or more partitions.

7. The system of claim 6, wherein the system is further configured to, after activation of the scoped selected one of the one or more debug patches within the domain, deactivate the scoped selected one of the one or more debug patches without restarting the one or more running managed servers.

8. A method for dynamic debugging in an application server environment, comprising:

providing, at one or more computers, including an application server environment executing thereon,

a plurality of deployable resources which can be used within the application server environment,

one or more running managed servers, the one or more managed servers being within a domain, and

a debug framework, the debug framework comprising a debug patch directory, the debug patch directory containing one or more debug patches;

activating, upon an indication of a problem within the domain, a selected one of the one or more debug patches within the domain, the selected one of the one or more debug patches comprising at least one class, the selected one of the one or more debug patches designed to gather information about the problem within the domain; and

wherein upon activation of the selected one of the one or more debug patches within the domain, the one or more running managed servers are not restarted.

9. The method of claim 8, wherein the selected one of the one or more debug patches, upon activation within the domain, replaces at least one class within the domain, the at least one class of the debug patch having a same shape as at least one class within the domain.

10. The method of claim 8, further comprising:

logging the gathered information about the problem within a log, the log being accessible by a system administrator.

11. The method of claim 9, further comprising:

after activating the selected one of the one or more debug patches within the domain, deactivating the selected one of the one or more debug patches within the domain without restarting the one or more running managed servers.

12. The method of claim 8, wherein the application server environment comprises a multi-tenant application server environment, the method further comprising:

providing one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, that can be associated with a tenant.

13. The method of claim 12, wherein the activated selected one of the one or more debug patches within the domain is scoped to a partition of the one or more partitions.

14. The method of claim 13, further comprising:

after activating the scoped selected one of the one or more debug patches within the domain, deactivating the scoped selected one of the one or more debug patches within the domain without restarting the one or more running managed servers.

15. A non-transitory computer readable storage medium, including instructions stored thereon for dynamic debugging in an application server environment which when read and executed by one or more computers cause the one or more computers to perform steps comprising:

providing, at one or more computers, including an application server environment executing thereon,

a plurality of deployable resources which can be used within the application server environment,

one or more running managed servers, the one or more managed servers being within a domain, and

a debug framework, the debug framework comprising a debug patch directory, the debug patch directory containing one or more debug patches;

activating, upon an indication of a problem within the domain, a selected one of the one or more debug patches within the domain, the selected one of the one or more debug patches comprising at least one class, the selected one of the one or more debug patches designed to gather information about the problem within the domain; and

wherein upon activation of the selected one of the one or more debug patches within the domain, the one or more running managed servers are not restarted.

16. The non-transitory computer readable storage medium of claim 15, wherein the selected one of the one or more debug patches, upon activation within the domain, replaces at least one class within the domain, the at least one class of the debug patch having a same shape as at least one class within the domain.

17. The non-transitory computer readable storage medium of claim 15, the steps further comprising:

logging the gathered information about the problem within a log, the log being accessible by a system administrator.

18. The non-transitory computer readable storage medium of claim 15, the steps further comprising:

after activating the selected one of the one or more debug patches within the domain, deactivating the selected one of the one or more debug patches within the domain without restarting the one or more running managed servers.

19. The non-transitory computer readable storage medium of claim 16, wherein the application server environment comprises a multi-tenant application server environment, the steps comprising:

providing one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain, that can be associated with a tenant.

20. The non-transitory computer readable storage medium of claim 19, wherein the activated selected one of the one or more debug patches within the domain is scoped to a partition of the one or more partitions.
