DBA may need to flush the shared pool or the cursor of the query.
conn / as sysdba
alter system flush shared_pool; --- not recommend during the peak hours of the prod..
or,
select sql_text,address, hash_value, executions from v$sqlarea where sql_id = '&sqlid';
exec sys.dbms_shared_pool.purge('&address, &hash_value','c');
-- passing the address and hash_value from the previous query
