I am using our Production server with oracle 10g on Linux Enterprise version 5 with DELL server . Here when I make any expdp backup with parallel option then I got the below error :
---
Processing object type SCHEMA_EXPORT/JOB
Processing object type SCHEMA_EXPORT/REFRESH_GROUP
. . exported "ULTIMUS"."COR_GLMASTER_HIST" 40.14 GB 153039611 rows
. . exported "ULTIMUS"."TFN_IMP_LC_HIST" 17.75 GB 5355726 rows
ORA-39095: Dump file space has been exhausted: Unable to allocate 8192 bytes
Job "SYS"."SYS_EXPORT_SCHEMA_01" stopped due to fatal error at 20:19:54

I search the metalink and found a note "Doc ID 559692.1" for solution . Here the document says to split the backup dumpfile equal to parallel value.
Now, On another environment with oracle10g setup including Enterprise Linux 5.0 , I cannot found this types of error . Interesting matter is , that backup data is the redundant copy of the production data . There I use single dumpfile with parallel option . Both server we have 8 cpu .
My question is , is this problem related with any operating system configuration issue ? Does any os parameter depends on this parallel keyword ?
