DATA PROCESSING APPARATUS AND DATA PROCESSING APPARATUS PROGRAM FOR USE IN FAILURE ANALYSIS, DATA PROCESSING METHOD FOR USE IN FAILURE ANALYSIS, AND DATA PROCESSING METHOD FOR USE IN FAILURE ANALYSIS

摘要

PROBLEM TO BE SOLVED: To achieve efficient failure analysis while ensuring security.SOLUTION: A data processing apparatus analyzes a cause of a failure by reproducing a user environment 22 in a search environment 23 if the failure occurs in the user environment 22. At this time, an operation log created in the user environment 22 is acquired and input data input by an operator of the user environment 22 in the operation log is processed. The input data is processed such that a length of a character string and an arrangement of character types before processing match those after processing. Furthermore, a processing table 51 for associating data before processing with data after processing is created, so that the same character string is the same as that after processing.
