如何產生Oracle AWR報告____Oracle

Oracle效能分析入門學習中，遇到Oracle資料庫的效能問題，一般首要的步驟就是匯出AWR的分析報告，AWR是10g中新引入的一個工具，在這之前一般是利用statspack。要匯出AWR報告，只要利用Oracle的一個指令碼即可以完成，下面是我利用script錄製的一段匯出AWR report的過程。
首先進入$ORACLE_HOME/rdbms/admin目錄，在sqlplus下運行@awrrpt指令碼，按照提示一步一步就可以達成，匯出的格式有兩種，txt格式和html格式。
在OTN上，有一個DBA新feature系列，第六周就是專門講的這個feature，大家可以去那裡瞭解一下（中文的）

自己實驗做過html的，覺得很不錯，可以查看網頁形式的報告，可讀性強，用firefox命令可以查看html格式的網頁，如：firefox awrrpt_1_233_235.html，

會看到類似這樣的介面：
