Datapump export multiple of partitions?

Hi,

Im trying to export a large number of partitions in our dw. Over 3500.

Is there away to do this in one go in expdp? I think the parfile is limited to 4000 chars.

I tried something like this:

Created a table and populated it with the partitions I want to export:

CREATE TABLE dbmaint.expdp_par (script VARCHAR2(200));

INSERT INTO dbmaint.expdp_par (script)

  select table_name || ':' || partition_name from dbmaint.ldx_part_drop_script  where status = 20;

This is the par file:

DIRECTORY=DATA_PUMP_DIR

DUMPFILE=rensningTEST%U.dmp

LOGFILE=rensning.log

PARALLEL=6

INCLUDE=TABLE:"IN (SELECT SCRIPT FROM DBMAINT.EXPDP_PAR)"
