A system suited to scheduling print jobs for a printing system includes a first processing component which identifies preliminary attributes of print jobs to be printed on sheets. A job scheduler receives the preliminary attributes and assigns each of the print jobs to one of a plurality of job queues in time order for printing. Print jobs spanning the same time are scheduled for printing contemporaneously. In one mode of operation, the assignment of the print jobs to the job queues is based on their preliminary attributes and on the application of at least one constraint which affects contemporaneous printing of at least two of the plurality of print jobs. A second processing component identifies detailed attributes of the print jobs. A sheet scheduler receives information on the assignments of the print jobs and their detailed attributes and forms an itinerary for each sheet to be printed.

The invention is a method and apparatus for on-demand resource planning for unified messaging services. In one embodiment, multiple clients are served by a single system, and existing system resources are allocated among all clients in a manner that optimizes system output and service provider profit without the need to increase system resources. In one embodiment, resource allocation and job scheduling are guided by individual service level agreements between the service provider and the clients that dictate minimum service levels that must be achieved by the system. Jobs are processed in a manner that at least meets the specified service levels, and the benefit or profit derived by the service provider is maximized by prioritizing incoming job requests within the parameters of the specified service levels while meeting the specified service levels. Thus, operation and hardware costs remain substantially unchanged, while system output and profit are maximized.

A method of scheduling jobs in real time using a database management system is provided. An application task classifies jobs as any one transaction type of a hot type and a normal type. A processing area in a memory pool that is a common resource is allocated to the application task, and the job is transferred to a database job manager through a client application program interface (API). The job manager loads a request node of the job in a list of a transaction type corresponding to the job, of a mailbox of the DB task, which classifies job request nodes as the hot type and the normal type with respect to the type of transaction and manages the nodes, so that the job request node can be scheduled in units of transactions. The job manager transfers the job request nodes loaded in the mailbox for the DB task, one by one to the DB task so that the job request nodes can be processed in units of transactions in a manner in which a job corresponding to a hot-type transaction is processed with a priority over a job corresponding to a normal-type transaction, and between jobs of an identical truncation type, jobs are processed in order of job requesting time. The DB task loads through the job manager, the processing result of the job in a mailbox of the application task which requested the processing of the job, so that the corresponding application task can use the processing result in the future.
