Abstract

Methods, systems, and other embodiments for protecting a shared resource in a data processing system are described herein. In one embodiment, when responding to a request that requires use of the shared resource, determine whether a previously established sleep period for the shared resource has expired. If so, determine a health status of the shared resource based on one or more of applying an asymptotic transform to a percentage of time that a processing unit is idle and applying a linear transform to a session count for the shared resource. Then, determine whether the health status is sufficient to permit responding to the request; and if not, (i) determining an appropriate sleep period for the shared resource, (ii) initiating a sleep state for the shared resource for a period substantially equal to the determined appropriate sleep period; and (iii) exiting the sleep state and responding to the request.

First claim

That which is claimed is:

1. A method of protecting a shared resource in a data processing system, comprising:
receiving a request, wherein responding to the request requires use of the shared resource;
determining whether a previously established sleep period for the shared resource has expired;
responsive to determining that the previously established sleep period has expired, determining a health status of the shared resource based at least in part on applying an asymptotic transform to a percentage of time that a processing unit is idle;
determining whether the health status is sufficient to permit responding to the request;
responsive to determining that the health status is not sufficient to permit responding to the request,
(i) determining an appropriate sleep period for the shared resource,
(ii) initiating a sleep state for the shared resource for a period substantially equal to the determined appropriate sleep period; and
(iii) exiting the sleep state and responding to the request.

2. The method of claim 1 , wherein the shared resource is one of a database, a processing element, or a connection to a network.

3. The method of claim 1 , wherein the health status is determined by accessing data stored in a cache associated with the shared resource.

4. The method of claim 1 , wherein the appropriate sleep period for the shared resource is determined based on a characteristic of the resource.

5. The method of claim 1 , wherein the appropriate sleep period for the shared resource is determined based on a characteristic of the account that generated the request.

6. The method of claim 1 , wherein the appropriate sleep period for the shared resource is determined based on a characteristic of a multi-tenant data processing system.

7. The method of claim 1 , wherein:
(i) the data processing system is a multi-tenant data processing system that includes one or more of an Enterprise Resource Planning (ERP) application, a Customer Relationship Management (CRM) application, and an eCommerce application, and
(ii) the appropriate sleep period is determined by evaluating a function or rule set that is based at least in part on a value of a tenant's data that is associated with the ERP, CRM, or eCommerce application.

8. The method of claim 1 , wherein the determination of the health status is also based at least in part on applying a linear transform to a session count for the shared resource.

9. The method of claim 1 , wherein the health status is also based at least in part on applying an asymptotic transform to a percentage of time spent in memory management reclaiming garbage.

10. A computing system, comprising:
a central data storage element; and
an electronic data processor configured to execute a set of instructions, wherein when the instructions are executed, the computing system is caused to implement a process to
receive a request, wherein responding to the request requires use of a shared resource;
determine whether a previously established sleep period for the shared resource has expired;
responsive to determining that the previously established sleep period has expired, determine a health status of the shared resource based at least in part on applying a linear transform to a session count for the shared resource;
determine whether the health status is sufficient to permit responding to the request;
responsive to determining that the health status is not sufficient to permit responding to the request,
(i) determine an appropriate sleep period for the shared resource;
(ii) enter a sleep state for the shared resource for a period substantially equal to the determined appropriate sleep period; and
(iii) exit the sleep state and respond to the request.

11. The computing system of claim 10 , wherein the shared resource is one of a database, a processing element, or a connection to a network.

12. The computing system of claim 10 , wherein the health status is determined by accessing a cached measurement on the application server that indicates a load of the shared resource.

13. The computing system of claim 10 , wherein the health status is determined by evaluating a function or rule set that is based at least in part on a characteristic of the data processing system.

14. The computing system of claim 10 :
(i) wherein the computing system is a multi-tenant data processing system, and
(ii) the appropriate sleep period is determined by evaluating a function or rule set that is based at least in part on a value of a tenant's data associated with an application of the multi-tenant data processing system.

15. The computing system of claim 10 , wherein determining the appropriate sleep period for the shared resource further comprises determining the appropriate sleep period based on one or more of a characteristic of the shared resource, a characteristic of an account that generated the request, or a characteristic of the computing system.

16. The computing system of claim 10 , wherein the health status is determined by applying an asymptotic transform to one of (i) a percentage of time that a processing unit is idle, and (ii) a percentage of time spent in memory management reclaiming garbage.

17. A non-transitory computer-readable medium storing computer-executable instructions for protecting a shared resource that when executed by at least a processor of a computer cause the computer to:
receive a request, wherein responding to the request requires use of the shared resource;
determine whether a previously established sleep period for the shared resource has expired;
responsive to determining that the previously established sleep period has expired, determine a health status of the shared resource based at least in part on applying an asymptotic transform to a percentage of time that a processing unit is idle;
determine whether the health status is sufficient to permit responding to the request;
responsive to determining that the health status is not sufficient to permit responding to the request,
(i) determine an appropriate sleep period for the shared resource,
(ii) initiate a sleep state for the shared resource for a period substantially equal to the determined appropriate sleep period; and
(iii) exit the sleep state and respond to the request.

18. The non-transitory computer-readable medium of claim 17 , wherein the determination of the health status is also based at least in part on applying a linear transform to a session count for the shared resource.

19. The non-transitory computer-readable medium of claim 17 , wherein the health status is determined by applying an asymptotic transform to a percentage of time spent in memory management reclaiming garbage.

20. The non-transitory computer-readable medium of claim 17 , wherein the appropriate sleep period for the shared resource is determined based on at least one of (i) a characteristic of the resource, (ii) a characteristic of the account that generated the request, or (iii) a characteristic of a multi-tenant data processing system.
