Abstract

A system and method of implementing selective session replication utilizing request-based service level agreements. The present invention includes, but is not limited to, a method, system, and computer-usable medium for assigning a collection of priority ratings to a collection of tasks; comparing a current level of system resource usage utilized by a data processing system executing the collection of tasks with a predetermined threshold; and in response to comparing the current level of system resource usage, enabling session replication of at least one task among the collection of tasks according to the assigned collection of priority ratings and the current level of system resource usage.

Claims

1. A method comprising:

assigning a plurality of task priority ratings to a plurality of tasks;

comparing a current level of system resource usage utilized by a data processing system executing said plurality of tasks with a predetermined threshold; and

in response to said comparing said current level of system resource usage, enabling session replication of at least one task among said plurality of tasks according to said assigned plurality of task priority ratings and said current level of system resource usage.

2. The method according to claim 1, further comprising:

assigning a plurality of client priority ratings to a plurality of clients requesting executing of said plurality of tasks.

3. The method according to claim 2, wherein said enabling session replication further comprises:

in response to said comparing said current level of system resource usage, enabling session replication of at least one task among said plurality of tasks according to said assigned plurality of priority ratings, said current level of system resource usage, and said plurality of client priority ratings.

4. A data processing system comprising:

at least one processing unit;

an interconnect coupled to said at least one processing unit;

a system memory coupled to said interconnect;

a computer-usable medium embodying computer program code, said computer program code comprising instructions executable by said at least one processing unit and configured for;

assigning a plurality of task priority ratings to a plurality of tasks;

comparing a current level of system resource usage utilized by a data processing system executing said plurality of tasks with a predetermined threshold; and

in response to said comparing said current level of system resource usage, enabling session replication of at least one task among said plurality of tasks according to said assigned plurality of task priority ratings and said current level of system resource usage.

5. The data processing system according to claim 4, wherein said instructions are further configured for:

assigning a plurality of client priority ratings to a plurality of clients requesting executing of said plurality of tasks.

6. The data processing system according to claim 5, wherein said instructions are further configured for:

in response to said comparing said current level of system resource usage, enabling session replication of at least one task among said plurality of tasks according to said assigned plurality of priority ratings, said current level of system resource usage, and said plurality of client priority ratings.

7. A computer-usable medium embodying computer program code, said computer program code comprising computer executable instructions configured for:

assigning a plurality of task priority ratings to a plurality of tasks;

comparing a current level of system resource usage utilized by a data processing system executing said plurality of tasks with a predetermined threshold; and

in response to said comparing said current level of system resource usage, enabling session replication of at least one task among said plurality of tasks according to said assigned plurality of task priority ratings and said current level of system resource usage.

8. The computer-usable medium according to claim 7, wherein said embodied computer program code further comprises computer executable instructions configured for:

assigning a plurality of client priority ratings to a plurality of clients requesting executing of said plurality of tasks.

9. The computer-usable medium according to claim 8, wherein said embodied computer program code further comprises computer executable instructions configured for:

in response to said comparing said current level of system resource usage, enabling session replication of at least one task among said plurality of tasks according to said assigned plurality of priority ratings, said current level of system resource usage, and said plurality of client priority ratings.
