we introduced exporting in parallel to multiple files for spend up , but throw some error. my db and rac ars 11.2.0.3.

#cat dmp.sh
expdp system/”xxxx” directory=datapump tables=anbob.t1,ocs_anbob.return_step_detail_t filesize=1G dumpfile=ocs%U.dmp logfile=ocs.log parallel=4

#chmod +x dmp.sh

#nohup ./dmp.sh > longjobs.out 2>&1 &
[1] 7799188
#jobs
[1] + Running nohup ./dmp.sh > longjobs.out 2>&1 &

error output
# tail -f longjobs.out

database monitoring
select INST_ID,sid, serial#,program from gv$session s, dba_datapump_sessions d where s.saddr = d.saddr;
above will be show the expdp job cross 2 nodes.

Solution:
1. Create a directory object on clustered file system
2. Export without using parallel clause
expdp xx/xx dumpfile=test_%u.dmp logfile=test.log directory=temp_expdp schemas=test

3. Use CLUSTER option in expdp CLI
expdp xx/xx dumpfile=test_%u.dmp logfile=test.log directory=temp_expdp schemas=test cluster=n
This option will to constrain the job to run on the instance where it is started
