Oracle imp导入数据时报IMP-00032与IMP-00008的解决方法

Symptoms

You try to import an export dump using the original import utility (imp) and received the errors:

IMP-00032: SQL statement exceeded buffer length

IMP-00008: unrecognized statement in the export file

Let's follow the next example that demonstrates this.

\-- create a big table (with a large DDL, 1000 columns) in schema test

connect test/test

create table big\_table

(

col000000000000000000000000001 varchar2(4000) not null,

col000000000000000000000000002 varchar2(4000) not null,

col000000000000000000000000003 varchar2(4000) not null,

col000000000000000000000000004 varchar2(4000) not null,

col000000000000000000000000005 varchar2(4000) not null,

col000000000000000000000000006 varchar2(4000) not null,

col000000000000000000000000007 varchar2(4000) not null,

col000000000000000000000000008 varchar2(4000) not null,

col000000000000000000000000009 varchar2(4000) not null,

col000000000000000000000000010 varchar2(4000) not null,

.... 1000 columns

col000000000000000000000001000 varchar2(4000) not null

);

\-- insert one row into table

declare

i number := 1;

begin

insert into big\_table values

(

lpad (to\_char (i), 1000, '0'),

.... 1000 columns

lpad (to\_char (i), 1000, '0')

);

commit;

end;

Export the table with:

\#> exp test/test file=big\_table.dmp tables=big\_table

This ends with:

Export: Release 11.1.0.7.0 - Production on Mon Jun 22 11:52:53 2009

Drop the table in schema TEST and import it back from written dump with:

\#> imp test/test file=big\_table.dmp tables=big\_table

000000000000000...

. importing TEST's objects into TEST

Import terminated successfully with warnings.

Cause

The internal BUFFER (default 32 KB, if not specified in imp command line) is also used to transfer the DDL statements from export dump file to Oracle server. If the DDL exceeds the BUFFER length, then IMP-32 is raised.

To obtain the DDL length run at export (source) site the statement:

select dbms\_lob.getlength (dbms\_metadata.get\_ddl ('TABLE', 'BIG\_TABLE', 'TEST')) "SQL\_LENGTH" from dual;

SQL\_LENGTH

\----------

67270

1 row selected.

The length of the DDL statement is in this case 67270 bytes, which exceeds the default BUFFER length (30720 bytes ~ 32 KB).

Solution

Increase the BUFFER size:

\#> imp test/test file=big\_table.dmp tables=big\_table buffer=100000

and the import succeeds:

. . importing table          "BIG\_TABLE"          1 rows imported

Import terminated successfully without warnings.
