Abstract

A computer system has a dual structure including a current system and an auxiliary system. When the current system stops because of server down, a setting module of the auxiliary system acquires an operation log and an operation management procedure from the current system and analyzes the operation log to specify to which part of the operation management procedure has been completed. The setting module performs comparative analysis of the operation log of the current system and communication log. The setting module extracts, from a result of the comparative analysis, information for returning the auxiliary system to a state of work at the stop of the execution of the current system. To resume the stopped work, the setting module sets the information in the auxiliary system.

Dependent claims

A computer-readable recording medium that stores therein a computer program for enabling recovery of an information system including an operation management function and an execution control function, the operation management function executing work according to an instruction from the execution control function, the execution control function controlling the operation management function to execute the work based on operation management information defining work content and work order for the work, the computer program causing a computer to execute:

acquiring, when the operation management function executes the work according to the instruction from the execution control function, communication history information concerning communication performed between the operation management functions and the execution control function;
storing the communication history information;
specifying, when the execution control function stops while the work is executed by the operation management function, a returning location in the work content and the work order, based on operation history information of the execution control function and the communication history information;
and
returning, according to the returning location, the information system to a state of work at the stop of the execution control function.
