Hi,

You can get ” ORA-02080: database link is in use ” error during the drop any user.

 

Details of error are as follows.

ORA-02080: database link is in use

Cause: a transaction is active or a cursor is open on the database link given in the alter session close database link <link> command.
Action: commit or rollback, and close all cursors






Check the existing Database links as follows.
SQL>  select db_link,logged_on,open_cursors from v$dblink;

 

 

To solve this error, You should increase the open_links parameter as follows.

alter system set open_links=20 scope=spfile sid='*';
alter system set open_links_per_instance=20 scope=spfile sid='*';


Then restart database to activate this parameter as follows.
 
shutdown immediate;
startup

 

If you don’t want to increase open_links because of restart database, then you can close the existing database links as follows.

 

SQL> exec DBMS_SESSION.CLOSE_DATABASE_LINK (Database_Link_Name);

SQL> alter session close database link Database_Link_Name;
