Abstract(in English) | Noticing that application programs handle files as a unit of input and output, we proposed a Directory Oriented Buffer Cache Mechanism. The proposed mechanism gives a high priority to important directories, which are associated with important jobs. Files in the important directories are given a high priority, and its blocks files are cached with the high priority. The proposed mechanism makes processing of important jobs frequently faster. However, the proposed mechanism degrades the performance of the processing in some cases due to three problems of it. This paper describes the three problems of the proposed mechanism. Then, this paper describes upper limit function of protected area and buffer migration function that solve the three problems. |
