Abstract

A management system manages one or more infrastructures, and a processor of the management system executes a plurality of consecutive processes on the infrastructure in response to a request, determines whether an error occurs during execution of the plurality of consecutive processes, selects a handling based on at least one of a classification of the error, an execution status of the processes, and a preset handling start condition when the error occurs, and executes the selected handling.

First claim

What is claimed is:

1 . A management system that manages one or more infrastructures, the management system comprising:
a processor, wherein the processor:
executes a plurality of consecutive processes on the infrastructure in response to a request;
determines whether an error occurs during execution of the plurality of consecutive processes;
selects a handling based on at least one of a classification of the error, an execution status of the processes, and a preset handling start condition when the error occurs;
executes the selected handling,
wherein, when the classification of the error is temporary, the processor selects a retry for re-executing a process in which the error occurs, and
wherein, when the classification of the error is not temporary, the processor selects a rollback for returning to a state before the execution of the plurality of consecutive processes, or selects a suspension in a state during the execution of the plurality of consecutive processes,

performs, when the error occurs, trial calculation on a rollback completion time taken for the rollback and a request completion time taken for executing a process subsequent to the process in which the error occurs in the plurality of consecutive processes and compares the rollback completion time with the request completion time; and
selects the handling based on a result of the comparison.

2 . The management system according to claim 1 , wherein the processor further:
selects the rollback when the rollback completion time is shorter than the request completion time as the result of the comparison; and selects the suspension when the rollback completion time is longer than the request completion time as the result of the comparison.

3 . The management system according to claim 1 , wherein
the handling start condition includes a state of the infrastructure, and when it is determined that the handling is executable based on the handling start condition, the processor selects the handling.

4 . The management system according to claim 1 , wherein
when the suspension is selected, the processor presents a handling procedure to be performed by a user to the user.

5 . The management system according to claim 1 , wherein
the processor selects the handling according to a preset priority order.

6 . The management system according to claim 5 , wherein
the priority order includes at least one of a retry priority, a rollback priority, a user presentation priority, a candidate selection, an operation completion time priority, and a cost priority.

7 . A management method of a management system that manages one or more infrastructures, the management method comprising:
by a processor included in the management system:
executing a plurality of consecutive processes on the infrastructure in response to a request;
determining whether an error occurs during execution of the plurality of consecutive processes;
selecting a handling based on at least one of a classification of the error, an execution status of the processes, and a preset handling start condition when the error occurs;
executing the selected handling,
wherein, when the classification of the error is temporary, the processor selects a retry for re-executing a process in which the error occurs, and
wherein, when the classification of the error is not temporary, the processor selects a rollback for returning to a state before the execution of the plurality of consecutive processes, or selects a suspension in a state during the execution of the plurality of consecutive processes,

performing, when the error occurs, trial calculation on a rollback completion time taken for the rollback and a request completion time taken for executing a process subsequent to the process in which the error occurs in the plurality of consecutive processes and compares the rollback completion time with the request completion time; and
selecting the handling based on a result of the comparison.
