int	truncate(Transaction txn, boolean countRecords) Deprecated. It has not been possible to implement this method with correct transactional semantics without incurring a performance penalty on all Database operations. Truncate functionality has been moved to Environment.truncateDatabase(), which requires that all Database handles on the database are closed before the truncate operation can execute.
