Question

I would like to find out if any and which database links are being used, for a schema, and in which tables. Is it possible via the data dictionary somehow?

Is this possible with the Oracle RDBMS?

Answer 1

This will show you any database links set up on the database:

select * from dba_db_links;

You would then have to search for any queries or objects using the db link by doing a text search of them for the link syntax <tablename>@<dblink name>
