A datapump client needs to know 2 things. Where to put/read the dmp files and where the source schema is (to import or export from). The former is determined by specifying a connect identified 'expdp user@db', whereas the latter is determined by 'network_link'. It gets a little more complicated if you use both features. For example ... 1) export remote schema and put is on local host: expdp user/pwd network_link=remote_schema 2) export remote schema and put is on remote host: expdp user/pwd@remotedb remote_link=remote_schema There are mind-dizzying combination of this. There is one scenario I'm trying to accomplish and I can't. I do not think it is possible. export remote schema to local host dmp file and import to remote schema using same local host dmp. What do you think? Thank you ... ---------------------------------------- Fred Habash, Database Solutions Architect (Oracle OCP 8i,9i,10g,11g)
