实用解析dmp文件内容

配置实验环境：  1.1 生产三个文件
 exp woo/oracle table=dump_table file=1.dmp;
 expdp woo/oracle tables=dump_table directory=dhome dumpfile=2.dmp;
 touch 3.dmp
 
 
 
2.创建随机数据
 
SQL> create table dump_table as 
  2  select rownum as id,
  3                  to_char(sysdate + rownum / 24 / 3600, 'yyyy-mm-dd hh24:mi:ss') as inc_datetime,
  4                  trunc(dbms_random.value(0, 100)) as random_id,
  5                  dbms_random.string('x', 20) random_string
  6             from dual
  7           connect by level <= 10;
Table created.

SQL> desc dump_table;
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 ID                                                 NUMBER
 INC_DATETIME                                       VARCHAR2(19)
 RANDOM_ID                                          NUMBER
 RANDOM_STRING                                      VARCHAR2(4000)

 SQL> select count(*) from dump_table;
  COUNT(*)
----------
        10
 
 
3.生成如下文件
 
[oracle@ora11grac1 ~]$ ls -rtl
total 212
-rw-r--r-- 1 oracle oinstall 16384 Mar 18 15:06 1.dmp
-rw-r----- 1 oracle asmadmin 98304 Mar 18 15:13 2.dmp
-rw-r--r-- 1 oracle asmadmin  1071 Mar 18 15:14 export.log
-rw-r----- 1 oracle asmadmin 98304 Mar 18 15:14 3.dmp
 
 
4.判断文件室友哪个版本生成的
 
[oracle@ora11grac1 ~]$ sed -n 1p 1.dmp
EXPORT:V11.02.00
 
 
5.判断文件类型
 
SQL> set serveroutput on
SQL> declare
  2   v_filetype    NUMBER;                 -- 0=unknown 1=expdp 2=exp 3=ext
  3   v_info_table  sys.ku$_dumpfile_info;  -- PL/SQL table with file info
  4  begin
  5   dbms_datapump.get_dumpfile_info(
  6    filename => '1.dmp',
  7    directory => upper('dhome'),
  8    info_table => v_info_table, filetype => v_filetype);
  9    dbms_output.put_line('Filetype : ' || v_filetype);
 10  end;
 11  /
Filetype : 2

SQL> set serveroutput on
SQL> declare
  2   v_filetype    NUMBER;                 -- 0=unknown 1=expdp 2=exp 3=ext
  3   v_info_table  sys.ku$_dumpfile_info;  -- PL/SQL table with file info
  4  begin
  5   dbms_datapump.get_dumpfile_info(
  6    filename => '2.dmp',
  7    directory => upper('dhome'),
  8    info_table => v_info_table, filetype => v_filetype);
  9    dbms_output.put_line('Filetype : ' || v_filetype);
 10  end;
 11  /
Filetype : 1
PL/SQL procedure successfully completed.

  4  begin
  5   dbms_datapump.get_dumpfile_info(
  6    filename => '3.dmp',
  7    directory => upper('dhome'),
  8    info_table => v_info_table, filetype => v_filetype);
  9    dbms_output.put_line('Filetype : ' || v_filetype);
 10  end;
 11  /
Filetype : 1

  9    dbms_output.put_line('Filetype : ' || v_filetype);
 10  end;
 11  /
Filetype : 0
PL/SQL procedure successfully completed.
 
 
6.数据库字符集，数据库名称，操作系统类型，操作系统名称
 
[oracle@ora11grac1 ~]$ sed -n 1p 2.dmp
\ÒÂÇg€¼uC¡ÈÃë KàS
H€"WOO"."SYS_EXPORT_TABLE_01"x86_64/Linux 2.4.xxora11grac1:woo1AL32UTF8 11.02.00.04.00001:001:000001:000001ÿÿ$$
 
 
7.判断文件所属表空间或用户
 
[oracle@ora11grac1 ~]$ sed -n 2p 1.dmp
DWOO
 
 
8.导出方式，USER,TABLE,
 
[oracle@ora11grac1 ~]$ sed -n 3p 1.dmp
RTABLES
 
 
9.判断文件数据块大小
 
[oracle@ora11grac1 ~]$ sed -n 4p 1.dmp
