ORA-01591: lock held by in-doubt distributed transaction string
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.
