All Implemented Interfaces:

java.io.Serializable

public class LockNotAvailableException
extends LockConflictException

Thrown when a non-blocking operation fails to get a lock. Non-blocking transactions are configured using TransactionConfig.setNoWait(boolean).

The Transaction handle is not invalidated as a result of this exception.

For compatibility with prior releases, LockNotGrantedException is thrown instead of LockNotAvailableException 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 JE applications.

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.
