商品描述
Cut through the complexity of Oracle tuning by focusing on the small set of patterns that cause most SQL slowdowns.
This Apress Pocket Guide distills those recurring patterns into a concise, workflow-driven handbook that helps you diagnose slow SQL quickly and apply practical fixes with confidence. It delivers compact, field-tested techniques that clarify why queries run slowly and how to improve them through execution plan analysis, indexing strategy, statistics management, and efficient SQL design.
Across a tightly scoped set of chapters designed for fast reference, this guide shows you how to read Oracle execution plans, identify inefficient access paths, prevent plan instability, and correct common tuning mistakes found in real applications. You build practical habits that reduce full table scans, improve join performance, stabilize execution plans, and avoid regressions--without requiring advanced DBA tools or deep internals knowledge. Streamlined for busy engineers, it helps you reach solutions faster and strengthen the long-term performance reliability of your Oracle SQL workloads.
What You Will Learn
- Diagnose slow SQL using a short, repeatable tuning workflow that highlights real bottlenecks
- Read Oracle execution plans with confidence and spot inefficient operations quickly
- Improve access paths through indexing strategy, SQL rewrites, and statistics-aware tuning
- Stabilize execution plans and reduce regressions with practical plan-management techniques
- Address locking, blocking, and concurrency symptoms common in production workloads
- Optimize high-volume and high-frequency query patterns for scalable performance
- Strengthen application-layer and configuration practices that affect SQL performance
- Build proactive tuning habits that support long-term reliability in Oracle-based systems
Who this Book Is For
Developers; data engineers; DBAs; backend and full-stack engineers; technical leads working with Oracle SQL.
商品描述(中文翻譯)
透過聚焦於造成大多數 SQL 效能下降問題的少數幾種模式，化繁為簡，掌握 Oracle 調校的核心。
這本 Apress Pocket Guide 將這些反覆出現的模式濃縮成一本簡明、以工作流程為導向的手冊，協助您快速診斷速度緩慢的 SQL，並有信心地套用實務修正方法。本書提供精簡且經過實務驗證的技巧，說明查詢速度緩慢的原因，以及如何透過執行計畫分析、索引策略、統計資訊管理與有效率的 SQL 設計來改善效能。
本指南分成一組範圍明確、適合快速查閱的章節，帶您了解如何讀取 Oracle 執行計畫、找出沒有效率的存取路徑、避免計畫不穩定，以及修正常見於實際應用程式中的調校錯誤。您將建立實用的工作習慣，以減少全表掃描、改善 Join 效能、穩定執行計畫，並避免效能回退，而不需要進階 DBA 工具或深入了解資料庫內部運作機制。本書專為忙碌的工程師精簡設計，協助您更快找到解決方案，並提升 Oracle SQL 工作負載的長期效能可靠性。
