Therefore Keeping the plural apparatuses like servers, storages and routers in good working order is needed. On the other hand, shortage of server managers is serious. This is the reason why the opportunity for server managers to operate outside machines of their expertise are increasing. Those managers are likely to cause unexpected obstacles when they operate outside machines of their expertise. Although the managers must understand system configuration while maintaining servers, empirical intuition are needed to specify the cause of obstacles when obstacles happen. On this account, It is hard to do the repair work and learn know-how only in managers who do not have expertise about where applicable. As a technique to support repair work, there are some RCA methods. However it depends on the skilled managers to estimate why the obstacle happened. This proposal method supports managers who is outside of his/her area of expertise with using operation logs as a know-how-information. it can finally inhibit operation mistakes.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"94","bibliographic_titles":[{"bibliographic_title":"インターネットと運用技術シンポジウム2013論文集"}],"bibliographicPageStart":"87","bibliographicIssueDates":{"bibliographicIssueDate":"2013-12-05","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2013"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-21T13:16:52.131838+00:00","created":"2025-01-18T23:43:19.053855+00:00","links":{},"id":96466}
