Importing table partition

Question

Hello all.
I want to import only one partition of a table. The export that i have done is :
exp usernmae/pass tables=(table_name:partition_name) ....
And i want to import this partitino to another server with the same table_name.
What can i do, i have first to create the partition to the target table and use import utility Or i directly use import utility and import will create first the partition.
What the way to import it.
Because when i import it directly i had an error like this:
. . importing partition "TABLE_NAME":"PARTITION_NAME"
IMP-00058: ORACLE error 14400 encountered
ORA-14400: inserted partition key does not map to any partition
Import terminated successfully with warnings.
Thanks for your help.

that is your error, it is because:
ops$tkyte@ORA817DEV> select * from t;
USERC DATA
ACGA  hello
ACLJ  world
XXXX  ugh
the source table has usercodes we did not anticipate - and your data must also have the same issue.
to get this imported:
ops$tkyte@ORA920PC> drop table t;
Table dropped.
ops$tkyte@ORA920PC> create table t
  2  ( usercode1 varchar2(5),
  3    data      varchar2(10)
  4  )
  5  PARTITION BY LIST (usercode1)
  6      (partition p_acga VALUES('ACGA') ,
  7           partition p_aclj VALUES('ACLJ') ,
  8           partition the_rest values ( DEFAULT ) )
  9  /
Table created.

and there you go!  And then you can:

ops$tkyte@ORA920PC> select * from t partition(the_rest);
