Symptoms

You received the error message:

ORA - 39095 : " dump file space has been exhausted. Unable to allocate 4096 bytes"
jobsystem.sys_export_full_02 stops due to fatal error.

while performing DataPump export:

- when exporting a large number of tables then it completely stops
- the jobs may remain in the DataPump export tables
- no trace generated at the time of the failure.

Cause

You limited the number of files in DUMPFILE parameter with limited FILESIZE , i.e.:

full=Y
directory=dpump_dir
dumpfile=full_1.dmp,full_2.dmp,full_3.dmp,full_4.dmp
filesize=3000000000


This means max. 4 dump files with file size 3000000000 bytes (4x2.79 GB).

Solution

1. Use the dynamic format  (i.e dumpfile=full_%U.dmp) :

The 'wildcard' specification for the dump file can expand up to 99 files. If 99 files have been generated before the export has completed, it will again return the ORA-39095 error.

2. If this is yet not enough and more files are needed, a workaround would be to speciyy a bigger FILESIZE parameter.

3. If this is inconvenient, then another option is to use this syntax:

dumpfile=fullexp%U.dmp, fullexp2_%U.dmp, fullexp3_%U.dmp

which can expand up to 3*99 files.

If encountering problems containing the dump in a single directory using this solution, you may prefer this syntax:

dumpfile=dmpdir1:fullexp1_%U.dmp, dmpdir2:fullexp2_%U.dmp, dmpdir3:fullexp3_U.dmp

(assuming the 3 directory objects listed above had been already created first).
