Oracle Database Discussions

Dear Guru's,

For years we exported and imported our transportable tablespaces, but recently the export fails with the following error message:

EXP-00008: ORACLE error 29341 encountered
ORA-29341: The transportable set is not self-contained
ORA-06512: at "SYS.DBMS_PLUGTS", line 1143
ORA-06512: at line 1
EXP-00000: Export terminated unsuccessfully

We use Oracle9i in RedHat 3.4 on xSeries 336 machine.

The exporting command: exp parfile=export.f

Contents of export.f:

USERID="/ as sysdba"
TRANSPORT_TABLESPACE=y
TABLESPACES=JAFFA_TSB,BLOB_TSP
# Outcommented lines contains default value:
#GRANTS=Y
#CONSTRAINTS=Y
#TRIGGERS=Y
#INDEXES=Y
TTS_FULL_CHECK=TRUE
OBJECT_CONSISTENT=Y
STATISTICS=COMPUTE
FILE=syn_meta.dmp
LOG=syn_meta.log

These attempts were made:
EXECUTE dbms_tts.transport_set_check('BLOB_TSP', TRUE, TRUE);
SELECT * FROM transport_set_violations ==> "no rows selected"

Oracle support service has still no answer to this issue.

How can we find where the problem is? Can anybody help?

Thanks a lot in advance!
