Method and system for reducing by blocking occur in server / database-systems

The invention relates to a translated by a computer method for limiting the number of simultaneous requests in a data base system, comprising the steps of: - arranging requirements that are to be processed by the database system, in at least one queue (10); - defining a maximum value (SS) for simultaneous requests corresponding to the at least one queue (10); - monitoring at least one queue usage parameters, which at least corresponds to a queue and calculating a power value based on the at least one queue usage parameter, - dynamically adjusting the maximum value (SS) of simultaneous requests the at least one queue based on the power value (PF) in order to improve system performance, and - dynamic limiting the number of simultaneous requests the at least one queue (10) based on the dynamically adjusted maximum value (SS).
