=====================

--直到執行LINE#=58,也沒有物理讀取操作。

3. oralce 如何直到要從file#1，block#＝520上讀取呢？實際上這個資訊記錄file#1,block#=1上。
--回頭看轉載的開始的等待事件，每個資料檔案都要讀取block#=1

--透過bbed觀察：
BBED> set dba 1,1
DBA 0x00400001 (4194305 1,1)

BBED> p kcvfh.kcvfhrdb
ub4 kcvfhrdb @96 0x00400208

BBED> set dba 1,520
DBA 0x00400208 (4194824 1,520)

--在偏移量96記錄塊地址dba=0x00400208,正好等於set dba 1,520看到的結果。
--也可以轉儲檔案頭看看：

alter session set events 'immediate trace name FILE_HDRS level 12';
