Hi,

I am trying to import schema into exadata machine using impdp.
The impdp is failed to open dump file.
Starting "ICCS"."SYS_IMPORT_FULL_01": userid=iccs/******** full=y TABLE_EXISTS_ACTION=APPEND
DIRECTORY=EXP_FOR_EXADATA PARALLEL=4 DUMPFILE=exp_dataONLY_iccs_25062012_%U.dmp LOGFILE=exp_dataONLY_iccs_25062012.log

.....I verified that the file is exist in the file system :
[oracle@dm01db01 psdwh]$ ls -l /restore/psdwh/exp_dataONLY_iccs_25062012_04.dmp
-rwxrwxrwx 1 oracle oinstall 701464576 Jun 25 10:36 /restore/psdwh/exp_dataONLY_iccs_25062012_04.dmpI verified that the file has the same permission as oracle user :
dm01db01{oracle} /home/oracle >id
uid=1000(oracle) gid=1001(oinstall) groups=101(fuse),1001(oinstall),1002(dba)I also verified that i have a the right permission on the directory ABOVE :
cd /restore
ls -l
drwxrwxrwx  3 oracle oinstall         9216 Jun 27 19:15 psdwhI veified that the directory exists:
SQL> select * from dba_directories;
OWNER      DIRECTORY_NAME   DIRECTORY_PATH
SYS       EXP_FOR_EXADATA   /restore/psdwhI have read,write permission on the directory to PUBLIC , and as you can see there are some tables which successfully imported:
. . imported "ICCS"."CUST_S"                         19.78 MB  580379 rows
. . imported "ICCS"."CUST_SUM_CD"                    16.79 MB  843460 rowsPlease note that i am getting such an error each time that i am using expdp with PARALLEL and having %U in the dumpfile name .
e.g:
expdp userid=iccs/iccs@psdwh  content=data_only EXCLUDE=statistics DIRECTORY=EXP_FOR_EXADATA
PARALLEL=4 DUMPFILE=exp_dataONLY_iccs_25062012_%U.dmp LOGFILE=exp_dataONLY_iccs_25062012.logIf i am exporting without PARALLEL and %U , mean having just one dump file , i have no problem at all to import the file.
Any Advice ?
Thanks

The issue is most likely due to the directory not being accessible from all nodes in the rac. If it works with parallel=1 but not parallel>1 then the other nodes that are being used to import data, and since the file exists, then please check that the disk is accessible from all nodes in the rack.
