Re: impdp Issue



The only thing I can think of at present is that you're allowed to use the database link when you connect to SQL*Plus but impdp does something that requires the link to be defined differently (e.g. you've got a private database link, but your use of impdp requires a public database link).

I’m trying to import from one database to another via the network.  I’ve done this many, many times with no issues, until now.  I create the database link, put the entry in the tnsnames.ora file, and verified that all is good.  The tnsping returns correctly.  I can query the remote database from SQL*Plus with no issue, but when I try to run the impdp, I get:

 

ORA-39001: invalid argument value

ORA-39200: Link name "advcprod" is invalid.

ORA-12154: TNS:could not resolve the connect identifier specified

 

The source database is Oracle 12.1 on Red Hat 7, the destination database is Oracle 19 on Red Hat 8.  I’ve tried setting the SID and SERVICE_NAME in the tnsnames.ora file and it doesn’t matter, I get the same error either way.
