ORA-39095: Dump file space has been exhausted: Unable to allocate 8192 bytes

Uses can receive below error during the export in case if you did not provide enough file names

$expdp xxx/xxxx directory=EXP_DIR DUMPFILE=exp_user.dmp LOGFILE=exp_user.log SCHEMAS=EMPUSER FILESIZE=20m
…..

ORA-39095: dump file space has been exhausted: unable to allocate 4096 bytes
Job "EMPUSER"."sys_export_table_01" stopped due to fatal error at 10:05:03

You will also receive this error if you specify one dump file or a number less than parallelism value. The slave processes locking the file does not release the lock even after finishing as it wait other processes to write to the file.

$expdp xxx/xxxx directory= EXP_DIR DUMPFILE=exp_user.dmp LOGFILE=exp_user.log SCHEMAS=EMPUSER PARALLEL=5

ORA-39095: dump file space has been exhausted: unable to allocate 8192 bytes

DONOT use PARALLEL clause to avoid this error.

In case if you have space issue on file system, then you can generate multiple dumps on multiple file systems or disks.
