You may face with that error while you are working with dblink. Sometimes, after a remote operation a user wants to close the connection to the remote site to conserve resources.
Formal details lets look at the oerr:
ORA-02080, 00000, "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 command. Action: commit or rollback, and close all cursors
So how We can handle this error message? Here is the solution steps:
The three ways of closing the remote connections are:
- Exit out of the local connection. i.e logout of the local database. This will automatically disconnect the connection to the remote database for that session.
- Users with ALTER SESSION privilege can explicitly close the connection after the remote operation is complete, by issuing this command:
SQL> show parameter SESSION_CACHED_CURSORS->In my case value is 50
SQL> execute immediate ‘ALTER SESSION SET SESSION_CACHED_CURSORS = 0’;
SQL> ALTER SESSION CLOSE DATABASE LINK ; If you receive an ORA-2080: database link is in use, issue a COMMIT; and then the alter session command again.
- Run below command: SQL> dbms_session.CLOSE_DATABASE_LINK(‘####’);
SQL> execute immediate ‘ALTER SESSION SET SESSION_CACHED_CURSORS = 50’; This procedure basically does the ALTER SESSION CLOSE DATABASE LINK call as in Step 2 above.
