BLOB importing with IMP

Question

Hello,
I am trying to import a database dump to another location. This exercise gives an error when importing the table containing BLOB column.
My original database was in tablespace 'R' and owned by user 'R'. Now I want to load it to tablespace 'M' owned by user 'M'. What I understand is that the loader (IMP) still tries to create table with a BLOB column in 'R' tablespace while I want it to be created in 'M'.
What is the solution to this problem?
Kindly reply asap.

Well said Tom & Karen,
However, I have extracted a piece of information from the metalink, it might be helpful to you.
What are the errors you get and what type of export/import are you doing and have you tried SQL Loader which also supports loading of LOBs? The Utilities manual has information on how to accomplish export/import and load LOBs. If you are doing a direct path export then suggest running a conventional path export. Are you using any other features like Advanced Queuing and how big is the size of data, is it lesser than 4K? What kind of LOB specially you have and have you changed the database character set? If you are not using commit=y on import, suggest you try.

If you are trying to set up a user/schema for one(on his own tablespace), into which he can import tables (have BLOB and CLOB columns) which are maintained in another schema (and tablespace) then its documented as an restriction described in the Oracle8i Utilities
1. Import with INDEXFILE parameter to generate the script
that can be used to modify the LOB's tablespace clause.
$imp system/manager fromuser=scott tables=\(circul\)
indexfile=create_lob_table
2. Edit the generated script file create_lob_table.sql:
REM CREATE TABLE "SCOTT"."CIRCUL" ("CIRCUL_ID" VARCHAR2(8) NOT NULL
REM ENABLE, "FIC_CIRCUL" BLOB) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS
REM 255 LOGGING STORAGE(INITIAL 10240 NEXT 10240 MINEXTENTS 1 MAXEXTENTS
REM 121 PCTINCREASE 50 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
REM TABLESPACE "USERS" LOB ("FIC_CIRCUL") STORE AS (TABLESPACE "USERS"
REM ENABLE STORAGE IN ROW CHUNK 2048 PCTVERSION 10 NOCACHE LOGGING
REM STORAGE(INITIAL 10240 NEXT 10240 MINEXTENTS 1 MAXEXTENTS 121
REM PCTINCREASE 50 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)) ;
REM ... 0 rows
2.1 Remove the REM comments
2.2 Change the owner SCOTT by the new owner U1
2.2 Change the tablespace USERS by the TOUSER's tablespace NEW_TBS in the whole statement.
3. Run the script create_lob_tabl
4. Import the data only in the created table, ignoring the CREATE TABLE statement failure.
$imp system/manager fromuser=scott tables=\(circul\) ignore=y
