Reducing lock occurrences in server/database systems

A computer-implemented method for limiting the number of concurrent requests in a database system comprising the following steps:

• arranging requests to be handled by the database system in at least one queue;
• defining a maximum value (SS) of concurrent requests corresponding to the 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) in order to improve system performance and limiting the number of concurrent requests of the at least one queue dynamically based on the dynamically adapted maximum value (SS).
