A method, a system, an apparatus, and a computer program product are presented for reducing synchronization waits when unique sequential identifiers are being allocated for transactions committed to a database that are occurring in a multi-threaded server environment. A transactional object containing an identifier data item is created for a transaction in an object-oriented environment. A pre-process object is then generated that contains the transactional object; when subsequently processed, the pre-process object allocates a sequential identifier value for the identifier data item. The pre-process object is added to a list of pre-process objects that are to be processed prior to completing the transaction, such as committing the transaction to a database. After some initial business logic processing, a commit operation for the transaction is commenced during which the pre-process object is processed, thereby allocating a sequential identifier value for the identifier data item just prior to committing the transaction.
