基于机器学习的数据库故障预测与自愈技术

摘  要:随着数据库系统在现代信息技术中的核心地位日益凸显,其运行稳定性与可靠性成为研究热点。本研究旨在通过机器学习技术实现数据库故障的精准预测与自动化自愈,以提升系统运维效率并降低人工干预成本。研究采用监督学习与无监督学习相结合的方法,构建了多维度特征提取模型,用于捕捉数据库运行状态中的潜在异常模式,并设计了一种基于强化学习的自愈策略优化算法,能够根据预测结果动态调整修复方案。实验结果表明,该方法可将故障预测准确率提升至95%以上,同时显著缩短平均修复时间(MTTR),达到传统方法的两倍效率。本研究的主要创新点在于首次提出融合时序分析与深度学习的故障诊断框架,并实现了端到端的自动化运维流程,为智能化数据库管理提供了新思路。研究成果对推动数据库运维从被动响应向主动预防转变具有重要意义。

Abstract:As database systems increasingly occupy a central position in modern information technology, their operational stability and reliability have become research focal points. This study aims to achieve precise prediction of database failures and automated self-healing through machine learning technologies, thereby enhancing system maintenance efficiency and reducing the cost of human intervention. By integrating supervised and unsupervised learning approaches, a multi-dimensional feature extraction model was developed to capture latent anomaly patterns in database operational states. Additionally, a reinforcement learning-based self-healing strategy optimization algorithm was designed, which dynamically adjusts repair plans according to predictive outcomes. Experimental results demonstrate that this method can elevate the accuracy of failure prediction to over 95%, while significantly shortening the mean time to repair (MTTR) to twice the efficiency of conventional methods. A key innovation of this research lies in the first proposal of a fault diagnosis fr amework that integrates time-series analysis with deep learning, enabling an end-to-end automated operation and maintenance process. This study provides new insights into intelligent database management and plays a crucial role in advancing database maintenance from passive response toward proactive prevention.
