Abstract

The present invention relates to a method of workload management in a computer system (100), in which units of work (152) are organized into service classes (121), to which a certain amount of system resources (140) is provided, and in which a number of service class periods (122) is associated to each service class (121), characterized in that the workload behavior within at least one present service class period (122) is determined, and the number of available service class periods (122) is automatically adjusted based on the determined workload behaviour.

Claims

1. A method of workload management in a computer system (100),

in which units of work (152) are organized into service classes (121), to which a certain amount of system resources (140) is provided, and

in which a number of service class periods (122) is associated to each service class (121),

characterized in that

the workload behavior within at least one present service class period (122) is determined, and

the number of available service class periods (122) is automatically adjusted based on the determined workload behavior.

2. The method as claimed in claim 1, wherein the characteristics of service class periods (122) is automatically adjusted based on the determined workload behavior.

3. The method as claimed in claim 1, wherein the step of determining the workload behavior comprises determining the transaction completion time and determining the resource consumption of a transaction.

4. The method as claimed in claim 1, wherein the step of adjusting the number of available service class periods (122) comprises automatically creating an additional service class period (122).

5. The method as claimed in claim 1, wherein the step of adjusting the number of available service class periods (122) comprises automatically deleting a present service class period (122).

6. A data processing program for execution in a computer comprising software code portions for performing a method according to anyone of the preceding claim 1 when said program is run on said computer.

7. A computer program product stored on a computer usable medium, comprising computer readable program means for causing a computer to perform a method according to claim 1 when said program is run on said computer.

8. A workload manager for a computer system,

in which units of work are organized into service classes to which a certain amount of system resources is provided, and

in which a number of service class periods is associated to each service class,

characterized in that it comprises

means for determining the workload behavior within a present service class period, and

means for automatically adjusting the number of available service class periods based on the determined workload behavior.
