Abstract

Claims (63)

1. A method for upgrading a system, comprising:

determining a first group of modules of a plurality of modules of the system to be upgraded in a first stage and a second group of modules of the plurality of modules of the system to be upgraded in a second stage, wherein the second stage is after the first stage;

upgrading the first group of modules in the first stage;

causing the upgraded first group of modules to provide a corresponding service; and

upgrading the second group of modules in the second stage while the upgraded first group of modules is providing the corresponding service,

wherein determining the first group of modules and the second group of modules comprises:

estimating a time period required for upgrading the plurality of modules;

estimating corresponding time points at which the plurality of modules will provide services;

including, based on an estimate that the first module of the plurality of modules will provide a service before the time period ends, the first module in the first group of modules; and

including, based on an estimate that the second module of the plurality of modules will provide a service after the time period ends, the second module in the second group of modules.

2. The method according to claim 1 , wherein estimating the corresponding time points at which the plurality of modules will provide the services comprises:

acquiring historical information related to the plurality of modules, the historical information indicating corresponding historical time points at which the plurality of modules provides the services; and

estimating the corresponding time points at which the plurality of modules will provide the services based on the historical information.

3. The method according to claim 1 , wherein determining the second group of modules further comprises:

including, based on a determination that a third module of the plurality of modules is disabled, the third module in the second group of modules.

4. The method according to claim 1 , wherein determining the second group of modules further comprises:

including, based on a determination that a fourth module of the plurality of modules is enabled but is not configured with a valid task for providing a service, the fourth module in the second group of modules.

5. The method according to claim 1 , wherein upgrading the second group of modules in the second stage comprises:

upgrading the second group of modules using a background process during the second stage.

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

causing the plurality of modules to stop providing the corresponding services before upgrading the modules in the system.

7. An electronic device, comprising:

at least one processing unit; and

at least one memory, the at least one memory being coupled to the at least one processing unit and storing instructions to be executed by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the electronic device to perform a method, the method comprising:

determining a first group of modules of a plurality of modules of the electronic device to be upgraded in a first stage and a second group of modules of the plurality of modules of the electronic device to be upgraded in a second stage, wherein the second stage is after the first stage from a plurality of modules of the electronic device;

upgrading the first group of modules in the first stage;

causing the upgraded first group of modules to provide a corresponding service; and

upgrading the second group of modules in the second stage while the upgraded first group of modules is providing the corresponding service,

wherein determining the first group of modules and the second group of modules comprises:

estimating a time period required for upgrading the plurality of modules;

estimating corresponding time points at which the plurality of modules will provide services;

including, based on an estimate that a first module of the plurality of modules will provide a service before the time period ends, the first module in the first group of modules; and

including, based on an estimate that a second module of the plurality of modules will provide a service after the time period ends, the second module in the second group of modules.

8. The electronic device according to claim 7 , wherein estimating the corresponding time points at which the plurality of modules will provide the services comprises:

acquiring historical information related to the plurality of modules, the historical information indicating corresponding historical time points at which the plurality of modules provides the services; and

estimating the corresponding time points at which the plurality of modules will provide the services based on the historical information.

9. The electronic device according to claim 7 , wherein determining the second group of modules further comprises:

including, based on a determination that a third module of the plurality of modules is disabled, the third module in the second group of modules.

10. The electronic device according to claim 7 , wherein determining the second group of modules further comprises:

including, based on a determination that a fourth module of the plurality of modules is enabled but is not configured with a valid task for providing a service, the fourth module in the second group of modules.

11. The electronic device according to claim 7 , wherein upgrading the second group of modules in the second stage comprises:

upgrading the second group of modules using a background process during the second stage.

12. The electronic device according to claim 7 , wherein the actions further comprise:

causing the plurality of modules to stop providing the corresponding services before upgrading the modules in the electronic device.

13. A computer program product, the computer program product being tangibly stored in a computer storage medium and comprising machine-executable instructions, the machine-executable instructions, when executed by a device, causing the device to execute the method comprising:

determining a first group of modules of a plurality of modules of a system to be upgraded in a first stage and a second group of modules of the plurality of modules of the system to be upgraded in a second stage, wherein the second stage is after the first stage;

upgrading the first group of modules in the first stage;

causing the upgraded first group of modules to provide a corresponding service; and

upgrading the second group of modules in the second stage while the upgraded first group of modules is providing the corresponding service,

wherein determining the first group of modules and the second group of modules comprises:

estimating a time period required for upgrading the plurality of modules;

estimating corresponding time points at which the plurality of modules will provide services;

including, based on an estimate that a first module of the plurality of modules will provide a service before the time period ends, the first module in the first group of modules; and

including, based on an estimate that a second module of the plurality of modules will provide a service after the time period ends, the second module in the second group of modules.

14. The computer program product according to claim 13 , wherein estimating the corresponding time points at which the plurality of modules will provide the services comprises:

acquiring historical information related to the plurality of modules, the historical information indicating corresponding historical time points at which the plurality of modules provides the services; and

estimating the corresponding time points at which the plurality of modules will provide the services based on the historical information.
