All Implemented Interfaces:

java.io.Serializable

public class LockTimeoutException
extends LockConflictException

Thrown when multiple threads are competing for a lock and the lock timeout interval is exceeded for the current operation. This is normally because another transaction or cursor holds a lock for longer than the timeout interval. It may also occur if the application fails to close a cursor, or fails to commit or abort a transaction, since any locks held by the cursor or transaction will be held indefinitely.

This exception is not thrown if a deadlock is detected, even if the timeout elapses before the deadlock is broken. If a deadlock is detected, DeadlockException is always thrown instead.

The lock timeout interval may be set using EnvironmentConfig.setLockTimeout(long, java.util.concurrent.TimeUnit) or Transaction.setLockTimeout(long, java.util.concurrent.TimeUnit).

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

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.
