Abstract

The present invention is directed to a method, a computer readable medium and a and a system of managing consumption of computing environment resources by multiple applications that features limiting resource consumption based upon examination of the total real-time resources of a computing environment being consumed rather than by the total resources available. The method includes observing communication between computing resources and multiple applications to obtain a real usage profile (RUP), for one of the multiple applications. A request to consume resources of the computing environment is received for one of the multiple applications. It is determined whether the whether granting access in response to the request violates a desired usage profile (DUP) based upon real usage profile. The computer-readable medium includes computer instructions to facilitate carrying-out of the functions of the claimed method by a general computing system. The system includes features capable of carrying-out the functions of the method.

Claims

1. A method of managing consumption of computing environment resources by multiple applications, said method comprising:

observing communication between said computing resources and said multiple applications to obtain a real usage profile (RUP), for one of the multiple applications, wherein said computing resources are threads from a thread pool;

receiving a request to consume resources of said computing environment for said one of said multiple applications, wherein said computing environment includes a virtual machine layer with an application server that runs said multiple applications;

determining whether granting said access violates a desired usage profile (DUP) based upon said RUP, were said request granted.

2. The method as recited in claim 1 wherein determining further includes ascertaining whether said one of said multiple applications has exceeded a resource consumption limit.

3. The method as recited in claim 1 wherein determining further includes ascertaining whether said one of said multiple applications has exceeded a resource consumption limit during a predetermined period of time.

4. The method as recited in claim 1 further including establishing said DUP by ascertaining a number of threads in said computing environment and establishing a maximum percentage of said number of threads over which said one of said multiple applications may

communicate.

5. The method as recited in claim 1 further including generating additional RUPs for the remaining applications of the multiple applications, with each RUP being associated with one of said multiple applications that differs from the RUP associated with the remaining applications of said multiple applications and ascertaining whether said one of said multiple applications has exceeded a resource consumption limit based upon the RUPs of the remaining applications of said multiple applications.

6. The method as recited in claim 5 further including assigning a DUP to the remaining applications of said multiple applications and determining whether of one of the DUP associated with one of said remaining applications changes in response to said request.

7. The method as recited in claim 5 further including assigning a DUP to the remaining applications of said multiple applications and changing one of the DUP associated with one of said remaining applications changes in response to said request.

8. A computer-readable medium having stored thereon instructions to manage consumption of resources of a computing environment by multiple applications, said instructions, when executed by a microprocessor, operable to:

observe communication between said computing resources and said multiple applications to obtain a real usage profile (RUP), for one of the multiple applications, wherein said computing resources are threads from a thread pool and wherein said computing environment includes a virtual machine layer with an application server that runs said multiple applications; and

determine whether granting said access violates a desired usage profile (DUP) based upon said RUP, were said request granted.

9. The computer-readable medium as recited in claim 8 including instructions to ascertain whether said one of said multiple applications has exceeded a resource consumption limit.

10. The computer-readable medium as recited in claim 8 wherein said instructions to determine further includes a sub-routine to ascertain whether said one of said multiple applications has exceeded a resource consumption limit during a predetermined period of time.

11. The computer-readable medium as recited in claim 8 wherein said instructions to determine further includes a sub-routine to ascertain whether said one of said multiple applications has exceeded a resource consumption limit based upon the RUP of the remaining applications of said multiple applications.

12. The computer-readable medium as recited in claim 8 further including instructions to assign a DUP to the remaining applications of said multiple applications and instructions to determine whether of one of the DUP associated with one of said remaining applications changes in response to said request.

13. The computer-readable medium as recited in claim 8 further including instructions to assign a DUP to the remaining applications of said multiple applications and decode to change one of the DUP associated with one of said remaining applications changes in response to said request.

14. The computer-readable medium as recited in claim 8 further including instructions to establish a DUP that includes a first sub-routine to ascertain a number of threads in said computing environment and a second sub-routine to establish a maximum percentage of said number of threads over which said one of said multiple applications may communicate.

15. A computing environment comprising:

a processing subsystem, wherein said processing subsystem includes a virtual machine layer with an application server;

a plurality of applications to be operated on by said processing subsystem to carryout a process having a set of threads associated therewith;

a protocol processing engine (PPE) to receive a request to consume resources of said computing environment by allowing access to one of said plurality of applications, said PPE including an application usage profile for a subset of said plurality of applications, wherein said resources are threads from a thread pool;

application resource allocation (ARA) logic to communicate between said PPE and a desired usage profile (DUP) for said plurality of applications;

an application resource allocation manager (ARAM) in data communication with said PPE, said ARAM storing an environment usage profile (EUP), with said ARA logic comparing said AUP with said DUP to determine whether to grant said request and said ARAM comparing said EUP with said DUP to determine whether to grant said request.

16. The environment as recited in claim 15 wherein said ARA logic, in response to said request, ascertains whether said one of said multiple applications has exceeded a resource consumption limit.

17. The environment as recited in claim 15 wherein said ARA logic, in response to said request, ascertains whether said one of said plurality of applications has exceeded a resource consumption limit during a predetermined period of time.

18. The environment as recited in claim 15 wherein said ARAM, in response to said request, ascertains whether said one of said plurality of applications has exceeded a resource consumption limit based upon the EUPs of the remaining applications of said plurality of applications.

19. The environment as recited in claim 15 wherein said ARA logic, in response to said said request, passes said request to said ARAM upon determining that said one of said plurality of application has not exceeded a resource consumption limit.

20. The environment as recited in claim 15 wherein said DUP includes information concerning a maximum percentage of threads of said computing environment over which each of said plurality of applications communicate.
