| ALL_DB_LINKS | Show the list of all Database links associated with the currently connected user. |
| USER_DB_LINKS | Show the list of all DB Links owned by the connected user. |
Extract DDL for oracle DB links
Using the below command we can get DDL from DB links, execute the output of the command.
SQL> set pages 999
SQL> set long 90000
SQL> set lin 120
SQL>SELECT 'SELECT dbms_metadata.get_ddl(''DB_LINK'',''' || db_link || ''',''' || owner || ''') as "Your DB Link DDL here" FROM dual;' AS "Execute below Query for DDL"
FROM dba_db_links WHERE db_link IN ('DB1LINK'); <<-- Enter your DB Link Name
