Oracle : Ошибка ORA-02051

"another session or branch in same transaction failed or finalized"
*Cause: A session at the same site with the same global transaction ID failed.
The failure could also be caused by an application error if an attempt
was made to update the database while another tightly coupled transaction
branch with the same global transaction ID was finalized or aborted.
*Action: No action necessary as the transaction will be automatically recovered.
In the case of an application error, make sure there are no more updates
to the database once the transaction manager has started two-phase commit
for tightly coupled distributed transaction.
