Oracle : Ошибка ORA-01591

"lock held by in-doubt distributed transaction %s"
*Cause: Trying to access resource that is locked by a dead two-phase commit
transaction that is in prepared state.
*Action: DBA should query the pending_trans$ and related tables, and attempt
to repair network connection(s) to coordinator and commit point.
If timely repair is not possible, DBA should contact DBA at commit
point if known or end user for correct outcome, or use heuristic
default if given to issue a heuristic commit or abort command to
finalize the local portion of the distributed transaction.
