Abstract

Radna svojstva (performanse) transakcijskih (OLTP) sustava imaju značajan utjecaj na njihovu prihvatljivost kod korisnika. Korisnički orijentiranu kvalitetu usluge (QoS) u najvećoj mjeri određuju sljedeći parametri: vrijeme odziva, raspoloživost, konzistencija i ažurnost. U ovom radu analizirana je povezanost između trenutnog opterećenja (propusnosti) poslužitelja baze podataka i vremena odziva upita. Mogućnost relativno pouzdanog predviđanja vremena odziva predstavlja temelj za automatizirani... More sustav odlučivanja koji može optimalno raspoređivati izvođenje upita - naročito onih zahtjevnijih koji bi mogli ugroziti dogovorenu razinu QoS. Less

Abstract (english)

The performances of On-Line Transaction Processing (OLTP) systems have a major effect on their acceptability to users. User oriented Quality of Service (QoS) of OLTP systems is determined with a response time, availability, consistency and currency. In this thesis the relationship between the system load/throughput and the query response time has been analyzed in the real OLTP system environment. A possibility of the accurate response time prediction may be a foundation for (automatized)... More decision-making for a DB query scheduling. The possible application of proposed method can be the estimation of the optimal moment for the complex query execution. Less
