Abstract

The Windows registry is a hierarchical database where the configuration data of a system or application programs is stored. In this paper, we presented and implemented a registry virtualization algorithm and measured its performance. The registry virtualization algorithm presented in the paper is called Copy-One-level On Write-Open(COOWO) that is a modified version of general Copy On Whte(COW) method to make it suitable for registry virtualization. In this paper, we implemented the proposed algorithm as a dynamically loadable library in Windows and applied it to many Windows application programs. This paper is meaningful since we described a registry virtualization algorithm in detail in situation where we can not find papers that describe the registry virtualization in detail, and we could find the performance of the algorithm can be used in the real applications.

윈도우 운영체제의 레지스트리는 시스템 및 응용 프로그램의 설정 데이터가 저장되는 계층적 구조를 가지는 데이터베이스이다. 본 논문에서는 윈도우 운영체제에서 레지스트리 가상화 알고리즘을 제안하고 구현하였으며 그 성능을 측정하였다. 본 논문에서 제안하는 레지스트리 가상화 알고리즘은 Copy-One-level On Write-Open(COOWO)이라고 불리는데 이는 일반적인 Copy On Write(COW) 방식을 레지스트리 가상화에 적합하도록 수정한 것이다. 본 논문에서는 제안한 알고리즘을 윈도우 운영체제에서 동적 라이브러리로 구현하였고 다양한 윈도우 응용 프로그램에 적용하였다. 본 논문은 레지스트리 가상화를 구체적으로 다루는 논문이 많지 않은 현실에서 레지스트리 가상화 알고리즘을 상세하게 기술하였고, 알고리즘의 성능이 실제 응용에 사용 가능하다는 것을 발견하였다는 점에서 의의가 있다.
