All Implemented Interfaces:
Serializable

public class LockPreemptedException
extends LockConflictException

Thrown when a lock has been "stolen", or preempted, from a transaction in a replicated environment.

The Transaction handle is invalidated as a result of this exception.

Locks may be preempted in a JE HA environment on a Replica system when the HA write operation needs a lock that an application reader transaction or cursor holds. This exception is thrown by a reader transaction or cursor method that is called after a lock has been preempted.

Normally, applications should catch the base class LockConflictException rather than catching one of its subclasses. All lock conflicts are typically handled in the same way, which is normally to abort and retry the transaction. See LockConflictException for more information.
