What exact patchset are you running on for 19c?

It is running on the 19c side. That is the only Oracle Home installed on that side, so it is using the 19c impdp.

Can you clarify one point ? On which side are you running impdp ? On the 12.1 source ? Or on the 19c target ? And is the impdp version you are using that of the source oracle home ? Or the target ?

ORA-12154: TNS:could not resolve the connect identifier specified Means the connection string you’ve used in the DB link does not resolve from the DB server. It will have nothing to do with pdbs/services/sids. Are you sure you made the entry in the right tnsnames file? Have you tnsping'ed from the DB server to confirm it works?

Unfortunately, you’re on 12.1 so you don’t have dbms_tns which helps test things here.

Thanks,
Andy

Are you using PDBs on 19c?

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.
