Abstract

A recording medium records an error management program for managing an error generated in an apparatus causes a computer to determine whether the error generated in the apparatus is a known error for which an action to cope with has been established. When the error generated in the apparatus is not determined to be a known error, the error is sorted as a new unknown error, and correlation of the new unknown error with an existing unknown error which has been determined to be an unknown error in the past is determined. When correlation of the new unknown error with the existing unknown error is found, new unknown error and the existing unknown error are classified into one group. Action priority of the classified unknown error group is determined; and the unknown error group for which the action priority has been determined is registered in an unknown error pool database.

Claims

1. A recording medium recording an error management program for managing an error generated in an apparatus, the error management program causing a computer to execute procedures comprising:

determining whether the error generated in the apparatus is a known error for which an action to cope with has been established;

when the error generated in the apparatus is not determined to be a known error, sorting the error as a new unknown error and determining correlation of the new unknown error with an existing unknown error which has been determined to be an unknown error in the past;

when the presence of the correlation of the new unknown error with the existing unknown error is found, classifying the new unknown error and the existing unknown error into one group;

deciding action priority of the classified unknown error group; and

registering, in an unknown error pool database, the unknown error group for which the action priority has been decided.

2. The recording medium according to claim 1,

wherein determining whether the error generated in the apparatus is a known error comprises searching, on the basis of a phenomenon of the error generated in the apparatus and a system configuration of the apparatus, a known error determination database which stores ID information of individual existing known errors in a corresponding relation to generated error phenomena and system configurations, thereby determining whether the error generated in the apparatus is the known error for which the action to cope with has been established.

3. The recording medium according to claim 1,

wherein determining correlation of the new unknown error with an existing unknown error comprises searching, on the basis of a phenomenon of the error generated in the apparatus and a system configuration of the apparatus, an unknown error grouping database which stores ID information of individual existing unknown errors in a corresponding relation to generated unknown-error phenomena and system configurations, thereby determining the correlation of the new unknown error generated in the apparatus with the existing unknown error, and

wherein classifying the new unknown error comprises, when the presence of the correlation of the new unknown error with the existing unknown error is found, classifying the new unknown error and the existing unknown error into one group and registering both unknown errors in the unknown error grouping database.

4. The recording medium according to claim 1,

wherein deciding action priority comprises searching, on the basis of a phenomenon of the error generated in the apparatus and a system configuration of the apparatus, an action priority determination database which stores action priorities of individual errors in a corresponding relation to generated error phenomena and system configurations, thereby deciding the action priority of the classified unknown error group, and setting the decided action priority of the classified unknown error group stored in the unknown error grouping database, which stores ID information of individual existing unknown errors, ID information of individual unknown error groups, and action priorities of the individual unknown error groups in a corresponding relation to generated error phenomena and system configurations.

5. The recording medium according to claim 1, the procedures further comprising:

receiving input of an action to cope with the unknown error in the unknown error group, the action being obtained as a result of error cause resolution, and

updating a status of the unknown error, for which the input of the action has been received, to completion of error cause resolution.

6. The recording medium according to claim 5, the procedures further comprising:

when the status of the unknown error is updated to the completion of error cause resolution, registering the unknown error, as a known error, in a known error determination database.

7. The recording medium according to claim 5, the procedures further comprising:

when the status of the unknown error is updated to the completion of error cause resolution, registering information of the unknown error registered in the unknown error pool database, as a known error, in the known error database which registers, as known errors, errors for which actions to cope with are established.

8. The recording medium according to claim 5,

wherein receiving input of an action further includes receiving input of a cost of the action to cope with the unknown error,

the procedures further comprising:

updating the action priority in the action priority determination database on the basis of the action to cope with the unknown error and the action cost.

9. The recording medium according to claim 5, the procedures further comprising:

when the status of the unknown error is updated to the completion of error cause resolution, deleting the ID information of the unknown error from the unknown error grouping database.

10. The recording medium according to claim 5,

wherein determining whether the error generated in the apparatus is a known error comprises, when one unknown error group includes an unknown error of which status has not been updated to the completion of error cause resolution, determining again, for all the unknown errors included in the one unknown error group and having statuses not updated to the completion of error cause resolution, whether each unknown error has become a known error.

11. An error management apparatus comprising:

a known error determination database storing ID information of individual known errors in a corresponding relation to generated error phenomena and system configurations;

an unknown error grouping database storing ID information of individual existing unknown errors in a corresponding relation to generated phenomena of the unknown errors and system configurations;

an action priority determination database storing action priorities of individual errors in a corresponding relation to generated error phenomena and system configurations;

an unknown error pool database registering unknown error groups;
