Oracle 11gR2 - Transaction lost in space

Hi all,

I'm currently struck with a transaction problem creating ORA-00054 errors in the application..

If i query V$TRANSACTION i can find a one day old transaction in prepared mode, but there isn't any sessions nor in doubt distributed transactions found

SQL> SELECT XID AS "txn id", XIDUSN AS "undo seg", XIDSLOT AS "slot", XIDSQN AS "seq", STATUS AS "txn status",start_date as "txn start date" FROM V$TRANSACTION;

txn id             undo seg       slot        seq txn status       txn start date
