【OCM】Oracle Database 10g: Performance Tuning(二)
今天在OU為期4天的OCM課程“Oracle Database 10g: Performance Tuning”的第二天。
該課程整體內容如下:
Lesson 1: Introduction
Lesson 2: Performance Tuning: Overview
Lesson 3: Statistics and Wait Events
Lesson 4: Metrics, Alerts, and Baselines
Lesson 5: Using Statspack
Lesson 6: Using Automatic Workload Repository
Lesson 7: Reactive Tuning
Lesson 8: Tuning the Shared Pool
Lesson 9: Tuning the Buffer Cache
Lesson 10: Automatic Shared Memory Management
Lesson 11: Checkpoint and Redo Tuning
Lesson 12: Tuning I/O
Lesson 13: Tuning PGA and Temporary Space
Lesson 14: Tuning Block Space Usage
Lesson 15: Performance Tuning: Summary
今天完成了第4、5和6章內容的講解。主要圍繞調優工具Statspack和AWR來展開,當然不乏對OEM影像化操作的推廣內容。個人認為對於監控和調優建議的檢視可以酌情使用EM或GC,當然對於命令列痴迷者也可以完全不用受這些工具的限制。
因為主要內容是Statspack和AWR等調優統計工具,因此課程中穿插了很多實驗。北京OU課堂的實驗機的配置了8G的記憶體,整體環境還是可圈可點的。
在AWR的講解過程中,發現了一個跨資料庫重啟時間點建立基線沒有報錯(應該有報錯資訊),但是在EM中點選建立的內容會給出報錯資訊的問題,這個問題可能與OU的環境有關,有興趣的朋友可以做一下這個測試。
exec dbms_workload_repository.create_baseline(32,68,'base_line');
Good luck.
