Ensuring that desired transactions are serviced in a timely manner in a database server. Resources are reserved ahead for transaction classes of interest, and the corresponding information is stored in a resource reservation table. In one embodiment, each transaction instance is admitted for servicing only if the reservation table indicates that sufficient resources are reserved for the transaction at the time instance the transaction is received. Resources may be reserved for specific transaction instances by using a label value, which would be contained in each transaction for which the time slot is reserved.
