Jack, true I forgot to mention that a local database on the client is still required which is a major drawback, but you can sometimes use this alternate expdp approach such as when you have an export file space issue on the source server so I think it is worth knowing about.

Mark,

That MOS doc is somewhat misleading. The Client machine must have an Oracle DB to which you connect in order to do the export from the DB specified by the DB Link. You cannot us ExpDP to create a set of export files on a simple client PC, for example. A database with a Directory to which you have read and write privs on is always required.

We use DataPump extensively and do huge Exports/Imports across DB Links. It's a great, great utility. I'm working right now on a PL/SQL package giving all our developers the ability to backup and restore selected objects using the DBMS_DataPump supplied package. It's taken a ton of reading the docs and Googling to work out the correct syntax for all the procedures, but the results are really slick.

I have not done this but I believe that

You can run expdp from a client writing the file to the database server You can run expdp from a client and write the export file to the client

Based on the following Oracle support note: How To Generate The DataPump Dump File On The Sever Or On The Client Machine (Doc ID 1385324.1)

The only capability of the good, old exp/imp that I miss is the fact that I can no longer perform it on the client side.

You can also use data pump which is far superior to import/export in my opinion.

Can you post the log of the export operation, and the parameters or parameter file you're using? I assume you're using expdp (data pump)?
