Solution Overview

Problem

Current methods for processing cipher change failures in database ciphertext data are inefficient, requiring manual analysis and retry time frame designation, leading to low operating efficiency and increased manual work.

Innovation Solution

An apparatus and method that store error information for failed cipher changes, determining a retry strategy based on the failure cause to automatically reperform the cipher change, thereby boosting success rates and reducing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual analysis and retry time frame designation is used for cipher change failures, then the process can handle failures, but the operating efficiency is low and manual work is increased

Engineering Contradiction:
Improvefailure processing capabilityVSAvoidoperating efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system automatically analyzes failure causes, determines retry strategies, and executes retries without manual intervention. The cipher change management system autonomously processes failures by storing error information, determining retry strategies based on failure causes, and automatically reperforming cipher changes for failed records, eliminating the need for manual log analysis and retry time frame designation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-establishes retry strategies for different failure causes before failures occur. When failures happen, the predetermined retry strategies are automatically applied based on the stored error information, eliminating the need for real-time manual decision-making and improving processing efficiency.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If manual analysis of failure logs is performed, then failure causes can be identified, but the amount of manual work is increased

Engineering Contradiction:
Improvefailure cause identification accuracyVSAvoidmanual work amount
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically identifies failure causes by analyzing error information stored in the database, eliminating the need for manual log analysis. The cipher change management system autonomously determines failure causes and selects appropriate retry strategies without human intervention, maintaining accuracy while reducing manual workload to zero.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements automatic feedback loops where failure information is captured, analyzed, and used to trigger appropriate retry actions. The error information is stored and automatically processed, creating a closed-loop system that continuously improves failure handling without requiring manual analysis.

Inventive Principle:
Principle #23Feedback

3Reliability

If cipher change is reperformed for all records in retry time frame, then potential failures are addressed, but processing efficiency is reduced by including successful records

Engineering Contradiction:
Improvefailure recovery completenessVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system segments the retry process by identifying and processing only the specific failed records rather than all records in a time frame. By storing error information for failed records and targeting retries only at those specific records, the system eliminates wasted processing on successful records while ensuring complete coverage of failed records.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies different processing quality to different records: failed records receive targeted retry processing with full error analysis, while successful records are excluded from retry processing. This localized approach optimizes resource allocation by concentrating processing efforts only where needed, improving overall efficiency while maintaining reliability.

Inventive Principle:
Principle #3Local quality

AI summary

This application provides a method and an apparatus for processing a failure of a cipher change of ciphertext data in a database, the method comprising: storing a record's error information when a cipher change of ciphertext data in the record fails, the error information comprising an identifier of the record and a failure cause; and determining a retry strategy based on the stored failure cause, and employing the retry strategy to reperform the cipher change of the ciphertext data in the record having the identifier. The technical scheme of this application boosts the success rate of cipher re-changing, reduces the amount of manual work, and also improves the operating efficiency of failure processing.
