Abstract

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.
