CREATE DATABASE LINK for information on creating database linksA private database link must be in your own schema. To drop a PUBLIC database link, you must have the DROP PUBLIC DATABASE LINK system privilege.
You must specify PUBLIC to drop a PUBLIC database link.
Specify the name of the database link to be dropped.
Restriction on Dropping Database Links You cannot drop a database link in another user's schema, and you cannot qualify dblink with the name of a schema, because periods are permitted in names of database links. Therefore, Oracle Database interprets the entire name, such as ralph.linktosales, as the name of a database link in your schema rather than as a database link named linktosales in the schema ralph.
Dropping a Database Link: Example The following statement drops the public database link named remote, which was created in "Defining a Public Database Link: Example":
DROP PUBLIC DATABASE LINK remote;
