It teaches you how to read the reports produced by these tools and how to go beyond formatted reports by querying the underlying diagnostic views directly with SQL. This direct-query approach gives you incredible flexibility and enables targeted analysis with great precision.\u003c\/p\u003e\n\u003cp\u003eBuilt on decades of consulting experience, this book provides practical scripts and real-world cases that demonstrate a repeatable diagnostic workflow. Start with AWR to understand the overall performance landscape and identify symptoms. Use ASH to validate hypotheses and drill down to precise root causes at the session, SQL, or object level. Use ADDM as a supplementary source of guidance to support and refine the investigation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat You Will Learn\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInterpret the mechanics behind AWR snapshots, ASH sampling, and ADDM findings.\u003c\/li\u003e\n\u003cli\u003eDetect anomalies by focusing on a few key sections instead of reading the entire AWR report.\u003c\/li\u003e\n\u003cli\u003eMeasure overall database health using AWR, ASH, and ADDM reports.\u003c\/li\u003e\n\u003cli\u003eQuery raw ASH, AWR, and ADDM view data directly with SQL.\u003c\/li\u003e\n\u003cli\u003eLeverage AWR, ASH, and ADDM together to troubleshoot Oracle performance issues.\u003c\/li\u003e\n\u003cli\u003eDevelop a reusable SQL toolkit for Oracle performance diagnostics.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWho This Book Is For\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003eDatabase administrators, consultants, and system architects who need practical, evidence-based Oracle performance diagnostics using ASH, AWR and ADDM, suitable for intermediate-to-advanced readers\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv\u003e\n\u003cp\u003e\u003cstrong\u003eYuan Yao\u003c\/strong\u003e has been working with Oracle databases since 1990.
