Machine上で稼働するUNIXの起動時間の短縮と設定の初期化のためにハイバネーションを利用しつつ,セキュリティパッチの適用やシステム設定の変更を可能とする手法を提案する.これらの提案に基づく大規模教育用計算機システムを実際に構築し評価した.その結果,提案手法によりそれぞれ,(1) 実用上問題のない速度と安定性でホームディレクトリを提供できていること,(2) UNIXのファイルの変更手法を更新するべきファイルの分量や緊急度により選択することで,実用に耐える時間で,更新作業を含めたUNIXの起動が実現できることを確認した.","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"This paper discusses a new method to construct educational computer systems with virtual machine technology, which serve two operating systems, i.e., Windows and UNIX on each terminal simultaneously. First, we propose a construction technique of the home directory, which can be simultaneously accessed from the both OSs in large-scale systems which consist of more than 1,000 terminals. In the proposed technique, SMB protocol needed for Windows is handled not by a single server but by each user terminal separately. We also propose a technique of performing application of security fixes and making a change of a system setup on that spot while we use hibernation in order to shorten the starting time of UNIX working on a virtual machine. A large-scale educational computer system based on these proposals was built, and its performance was evaluated. Consequently, we have confirmed that, (1) The home directory is offered with its performance satisfactory speed and stability in practical educational usage. (2) By chosing the technique of changing files of UNIX considering the quantity and urgency of update, the proposed technique can be used also by the large-scale system, and the starting time of UNIX including updating work is also within the range of practical usage.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"964","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"949","bibliographicIssueDates":{"bibliographicIssueDate":"2005-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"46"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"システム構築・運用技術"}]},"weko_creator_id":"1"},"id":10649,"updated":"2025-01-23T02:42:30.903912+00:00","links":{},"created":"2025-01-18T22:45:30.059671+00:00"}
