Claim:
1. A computer-implemented method for limiting the number of concurrent requests in a database system comprising: defining a maximum value (SS) of concurrent requests corresponding to at least one queue; monitoring at least one queue utilization parameter corresponding to the at least one queue and calculating a performance value (PF) based on the at least one queue utilization parameter; adapting the maximum value (SS) of concurrent requests of the at least one queue dynamically based on the performance value (PF); and limiting the number of concurrent requests of the at least one queue dynamically based on the dynamically adapted maximum value (SS), wherein after receiving a lock time-out of the database system, the maximum value (SS) of concurrent requests and the maximum length (QS) of the at least one queue is decreased in order to avoid further lock time-outs.
