Hi, I have following problem: update on table waits for lock (only one row tested) , there is no lock on the table in v$LOCK, analyze table validate structure gets ORA-00054, no rows in db_2pc_pending or pending_sessions , but there is one day old entry in V$TRANSACTION and V$LOCKED_OBJECT shows lock held by nonexistent session. Is there some possibility how to delete this entry from v$transaction without restarting the DB ? with dbms_transaction (I have no rights on it) ?
