[20140217]在toad使用跟蹤檔案.txt

我使用toad版本是12.0.0.61,今天使用生成跟蹤檔案，發現在介面上可以訪問跟蹤檔案的內容做一個測試看看。

SCOTT@test> @ver

BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

在toad 的session browser介面上，選擇要跟蹤的會話，如圖：

現在的版本支援3種方式，dbms_monitor,dbms_system,dbms_support.執行如下命令：

SCOTT@test> variable b number;
SCOTT@test> exec :b := 30

PL/SQL procedure successfully completed.

SCOTT@test> select * from dept where deptno=:b ;

    DEPTNO DNAME          LOC
---------- -------------- -------------
        30 SALES          CHICAGO

使用SQL Tracker的內容如下：

可以發現如下介面，發現一個錯誤，取出的繫結變數值不對。如圖：

另外可以從database=>diagnose=>trace file browser可以訪問。第一次要選擇create objects in toad schema或者create objects in my schema。
--說明：我在10g下這個過程失敗。建立這個java的東西失敗，不知道為什麼？那位知道請告訴我，謝謝！

有這個檢視語句，以及等待事件方便許多。
