ORACLE如何根据ITL找到前镜像的

  6              ( select t.instance from sys.v$thread  t,sys.v$parameter  v
  7              where v.name = 'thread' and (v.value = 0 or t.thread# = to_number(v.value))) i,
  8              ( select value from sys.v$parameter where name = 'user_dump_dest') d;

找到ITL记录，这里我们看0x03,应为update语句会lock一行，这里只有0x03的loc为1.

---------- ---------- ---------- ---------- ---------- ---------- ----------
         5         22       1017          2       1758        400         18
从DSI中可以知道ITL中的XID=usn#.slot#.wrap#
我们找到0X03中的XID=0x0005.016.000003f9
SQL> select to_number('0005','XXXXX') from dual;
TO_NUMBER('0005','XXXXX')
-------------------------
                        5
SQL> select to_number('016','XXXXX')from dual;
TO_NUMBER('016','XXXXX')
------------------------
                      22
SQL> select to_number('000003f9','XXXXXXXXX')from dual;
TO_NUMBER('000003F9','XXXXXXXX
------------------------------
                          1017
在V$TRANSACTION中记录的XIDUSN,XIDSLOT,XIDSQN与ITL中的xid相吻合，下面验证uba
从DSI中可以知道UBA=DBA.seq#.rec#
现在找到0X03中的uba=0x008006de.0190.12,0x008006de表示的是DBA，那么我们可以用dbms_utility.data_block_address_file，
dbms_utility.data_block_address_block这两个函数来解析DBA
SQL> select dbms_utility.data_block_address_file(to_number('008006de','xxxxxxxxxxxx'))file_id,dbms_utility.data_block_address_block(
  2  to_number('008006de','xxxxxxxxxxxx'))block_id from dual;

   FILE_ID   BLOCK_ID
---------- ----------
         2       1758
SQL> select to_number('0190','xxxx') from dual;
TO_NUMBER('0190','XXXX')
------------------------
                     400
SQL> select to_number('12','xxxx') from dual;

TO_NUMBER('12','XXXX')
----------------------
                    18
到此，ITL中的记录完全吻合v$transaction的记录，现在dump undo回滚段，找到更改的前镜像
SQL> alter system dump datafile 2 block 1758;
系统已更改。
SQL> select  d.value||'/'||lower(rtrim(i.instance, chr(0)))||'_ora_'||p.spid||'.trc' trace_file_name
  2              from
  3              ( select p.spid
  4              from sys.v$mystat m,sys.v$session s,sys.v$process p
  5              where m.statistic# = 1 and s.sid = m.sid and p.addr = s.paddr) p,
  6              ( select t.instance from sys.v$thread  t,sys.v$parameter  v
  7              where v.name = 'thread' and (v.value = 0 or t.thread# = to_number(v.value))) i,
  8              ( select value from sys.v$parameter where name = 'user_dump_dest') d;

找到dump出来的文件,undo block中也必须记录xid 0x0005.016.000003f9这个信息，因此我们可以在undo的dump文件中查找该ITL是否存在，已经找到该信息
UNDO BLK:

注意仔细查看XID与之前的XID 相同，然后我们根据cnt，也就是UBA=DBA.seq#.rec#中的rec#找到该记录rec#=x12也就是十进制的18也就是undo中的Rec #0x12,看这里的slt=0x16与ITL中记录xid 016吻合，到此ORACLE就能从这些信息找到前镜像了，下面我们还原c2 09,看看c2 09是否等于800

果然 c209等于800，到此，大家应该知道ORACLE是怎么通过ITL找到前纪录了吧。
