Distributed commit processing failed due to a communication error, site failure, gateway failure, or other error with the target DBMS accessed through the gateway. Updates at all sites participating in the transaction have been rolled back with the possible exception of the target DBMS. The target DBMS might have committed its updates if the failure occurred after the commit message was processed by the target DBMS.
If the updates on the target DBMS were committed, then the updates should be rolled back manually. Contact the target DBMS system administrator.
