All Implemented Interfaces:

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 thread. This may be the result of a deadlock or simply because a lock is held for longer than the timeout interval. 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.

For compatibility with JE 3.3 and earlier, DeadlockException is thrown instead of LockTimeoutException and TransactionTimeoutException when EnvironmentConfig.LOCK_OLD_LOCK_EXCEPTIONS is set to true. This configuration parameter is false by default. See EnvironmentConfig.LOCK_OLD_LOCK_EXCEPTIONS for information on the changes that should be made to all applications that upgrade from JE 3.3 or earlier.

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.
