public class HeuristicException

extends java.rmi.RemoteException

This exception indicates that one or more participants in a transaction has made a unilateral decision to commit or roll back updates without first obtaining the outcome determined by the transaction service.

Heuristic decisions are normally made only in unusual circumstances, such as communication failures, that prevent normal processing. When a participant makes a heuristic decision, there is a risk that the decision will differ from the consensus outcome, potentially resulting in loss of data integrity.

The subclasses of this exception provide more specific reporting of the incorrect heuristic decision or the possibility of incorrect heuristic decision.
