Abstract

In an embodiment, a method of resource pre-configuration includes obtaining, at a target system, configuration information about a resource that is predicted to be used by a transaction which will be executed on the target system. The resource is configured, at the target system, based on the configuration information. The configuring is before the transaction requests use of the resource.

First claim

What is claimed is:

1. A method of resource pre-configuration, the method comprising:
predicting, at a target system, a file that is to be used by a transaction when the transaction is executed on the target system, the predicting comprising:
selecting, by the target system, a reference system from a plurality of reference systems, wherein the selection of the reference system from the plurality of reference systems is based at least in part on a similarity between a workload of the target system and workloads of the plurality of reference systems and on a similarity between a task type of the target system and task types of the plurality of reference systems, wherein the selected reference system is currently using a plurality of candidate files; and
selecting, by the target system, the file from the plurality of candidate files based on predetermined criteria;

obtaining, at the target system, configuration information about the file in response to a start of the target system;
configuring, at the target system, the file based on the configuration information, the configuring being performed during the start of the target system and before the transaction requests use of the file; and
after the configuring of the file at the target system, monitoring, at the target system, times of use of the file within a predetermined time period, and upon the times of use being less than a predetermined threshold, restoring the file to a state before the configuring was performed.

2. The method according to claim 1 , wherein the obtaining, at the target system, configuration information about the file further includes:
receiving the configuration information about the file from the selected reference system.

3. The method according to claim 2 , wherein the selecting of the reference system from the plurality of reference systems includes:
selecting as the reference system a system having same or similar workload and a task type with the target system.

4. The method according to claim 2 , wherein the receiving the configuration information about the file from a reference system comprises:
receiving configuration information about candidate files from the reference system; and
determining, based on a predetermined criterion and from the candidate files, the file expected to be used by the transaction executed on the target system.

5. The method according to claim 2 , wherein the receiving the configuration information about the file from the reference system comprises:
receiving the configuration information about the file from the reference system at a running state of the target system.

6. The method according to claim 1 , further comprising:
collecting, at the target system, additional configuration information about an additional file used by a new transaction in response to the new transaction being executed on the target system; and
acting as a reference system by the target system by providing, by the target system, the additional configuration information about the additional file to another system of the plurality of reference systems, wherein the additional configuration information is provided by the target system to the other system in response to receiving a request from the other system for the additional configuration information.

7. The method according to claim 1 , wherein the configuring, at the target system, the file based on the configuration information comprises at least one of:
configuring an access state of the file;
configuring a storing state of the file; and
configuring a data consistency state of the file.

8. A system for resource pre-configuration, the system comprising:
a memory having computer readable instructions; and
one or more processors for executing the computer readable instructions, the computer readable instructions comprising:
predicting, at a target system, a file that is to be used by a transaction when the transaction is executed on the target system, the predicting comprising:
selecting, by the target system, a reference system from a plurality of reference systems, wherein the selection of the reference system from the plurality of reference systems is based at least in part on a similarity between a workload of the target system and workloads of the plurality of reference systems and on a similarity between a task type of the target system and task types of the plurality of reference systems, wherein the selected reference system is currently using a plurality of candidate files; and
selecting, by the target system, the file from the plurality of candidate files based on predetermined criteria;

obtaining, at the target system, configuration information about the file in response to a start of the target system;
configuring, at the target system, the file based on the configuration information, the configuring being performed during the start of the target system and before the transaction requests use of the file; and
after the configuring of the file at the target system, monitoring, at the target system, times of use of the file within a predetermined time period, and upon the times of use being less than a predetermined threshold, restoring the file to a state before the configuring was performed.

9. The system according to claim 8 , wherein the obtaining, at the target system, configuration information about the file further includes:
receiving the configuration information about the file from the selected reference system.

10. The system according to claim 9 , wherein the selecting of the reference system from the plurality of reference systems includes
selecting as the reference system a system having same or similar workload and a task type with the target system.

11. The system according to claim 9 , wherein the receiving the configuration information about the file from a reference system comprises:
receiving configuration information about candidate files from the reference system; and
determining, based on a predetermined criterion and from the candidate files, the file expected to be used by the transaction executed on the target system.

12. The system according to claim 9 , wherein the receiving the configuration information about the file from the reference system comprises:
receiving the configuration information about the file from the reference system at a running state of the target system.

13. The system according to claim 8 , wherein the computer readable instructions further comprise:
collecting, at the target system, additional configuration information about an additional file used by a new transaction in response to the new transaction being executed on the target system; and
acting as a reference system by the target system by providing, by the target system, the additional configuration information about the additional file to another system of the plurality of reference systems, wherein the additional configuration information is provided by the target system to the other system in response to receiving a request from the other system for the additional configuration information.

14. A computer program product for resource pre-configuration, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:
predicting, at a target system, a file that is to be used by a transaction when the transaction is executed on the target system, the predicting comprising:
selecting, by the target system, a reference system from a plurality of reference systems, wherein the selection
