Question

Oracle expdp REF_CONSTRAINT

Asked by: Geert_Gruwez

I have a oracle 10g database
i want to run a full export

i used this in batch:
expdp dbadm/ora920@m08u_upg FULL=Y CONTENT=ALL DUMPFILE=dpump1:exp.m08uupg.dmp LOGFILE=dpump1:exp.m08uupg.log

the process starts and runs for a while (see code)
and stops on Processing object type DATABASE_EXPORT/SCHEMA/TABLE/CONSTRAINT/REF_CONSTRAINT
I know it should still export triggers and it doesn't ...

then i go look in the table sys_export_full_01

what exactly would i be looking for to detect what's causing my export to fail ?

D:\exp>expdp dbadm/ora920@m08u_upg FULL=Y CONTENT=ALL DUMPFILE=dpump1:exp.m08uup
g.dmp LOGFILE=dpump1:exp.m08uupg.log

Hi Geert,

Did you check the target database host's alert log and check for trace files. The ORA-31762 is not normal, and could simply be caused by a bug. Look for more details on the target system, then if there are none, you can also turn on tracing for data pump to get more details.

expdp trace=<trace bit mask in hex> ...

I have seen a bug in Metalink regarding your issue, but it was on UNIX.

Can you consider applying 10.2.0.4 patchset?

by: Geert_GruwezPosted on 2009-08-19 at 06:53:14ID: 25132592

i can consider the patchset,
but i wouldn't execute it at the moment

i'm on leave as from tonight and nobody else to solve any arising problems ...

i'll check the tracing and logs

by: mrjoltcolaPosted on 2009-08-19 at 06:57:30ID: 25132650

Ok, postback here when you get more details.

Here is a quick link on expdp tracing: http://arjudba.blogspot.com/2009/04/how-to-tracediagnosis-oracle-data-pump.html

ORA-07445 is surely a bug. You can consider it the same as ORA-600 as far as calling support.
I would open the Oracle SR, I would not be surprised if they end up asking you to install the patch and/or verify the catalog.

by: Geert_GruwezPosted on 2009-08-19 at 07:18:47ID: 25132914

i reran the expdp job based on the trace from your post:
TRACE=1400300

i checked the trace file and at after a few passes for REF_CONSTRAINT it show up with the access vio
i posted the log section with the start of the error below
