Examples of com.sleepycat.je.LockTimeoutException

com.sleepycat.je.LockTimeoutException

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 {@link EnvironmentConfig#setLockTimeout} or {@link Transaction#setLockTimeout}.

The {@link Transaction} handle is invalidated as a result of thisexception.

For compatibility with JE 3.3 and earlier, {@link DeadlockException} isthrown instead of {@link LockTimeoutException} and {@link TransactionTimeoutException} when {@link EnvironmentConfig#LOCK_OLD_LOCK_EXCEPTIONS} is set to true. Thisconfiguration parameter is false by default. See {@link EnvironmentConfig#LOCK_OLD_LOCK_EXCEPTIONS} for information on the changesthat should be made to all applications that upgrade from JE 3.3 or earlier.

Normally, applications should catch the base class {@link LockConflictException} rather than catching one of its subclasses. All lockconflicts are typically handled in the same way, which is normally to abort and retry the transaction. See {@link LockConflictException} for moreinformation.
