COMPARISON OF THE PAGE REPLACEMENT ALGORITHMS FOR MEMORY MANAGEMENT

Abstract

In this article, memory management techniques which are very essential in database management system are discussed. The speed and performance values of transactions that occur on database management systems are greatly effected by buffer management algorithm. Buffer management algorithms are evaluated by creating parameters as different buffer size, block number and probabilistic values. Tests are performed and the results are discussed performance analysis of algorithms. Buffer management algorithms such as Basic, LRU, Clock and LRM were compared. As a result of the LRU and Clock algorithms are produced more successful results than other algorithms

Abstract

Bu makalede veri tabanı yönetim sistemlerinde önemli bir yere sahip olan bellek yönetim teknikleri ele alınmıştır. Veri tabanı yönetim sistemleri üzerinde gerçekleşen işlemlerin hız ve performans değerleri, kullanılan bellek yönetim algoritması tarafından büyük ölçüde etkilenmektedir. Bu çalışmada bellek yönetim algoritmaları, tampon boyutu, blok sayısı ve olasılıksal değerler gibi farklı parametler kullanılarak test edilmiştir. Sonuçlar üzerinden bellek yönetim algoritmalarının performans analizleri gerçekleştirilmiştir. Bellek yönetim algoritmalarından, temel bellek yönetim algoritması, FIFO, LRU, LRM ,CLOCK algoritmaları oluşturulan simülasyon üzerinde test edilmiştir. Simülasyon sonuçları değerlendirildiğinde LRU ve CLOCK algoritmalarının diğer test edilen algoritmalardan daha başarılı sonuçlar elde ettiği tespit edilmiştir
