针对双机互备和双站热备容灾方式单一、资源利用率和信息安全性不能兼顾的现象,本文描绘出一种建立在双站点基础上的服务器集群互动容灾的新框架。该框架可实现本地主站点不同服务器之间的局部容灾,亦可实现分别处于异地的主、被站点之间的整站容灾,充分体现了效率和安全性的统一。 相似文献

一、前言 容灾技术要求在主数据中心发生灾难时,在备份中心能够快速恢复业务系统的处理,在运行数据库应用的环境中,还需要考虑在备份中心备份关键的数据,并保证交易的一致性。严格上讲灾难恢复技术和容灾技术是有区别的。容灾技术是指数据操作的幸存能力,即指在灾难发生过程中或灾难发生后,数据中心计算机系统的应用系统能够正常运行和需要恢复的时间很短。但由于灾难恢复这一术语已被广泛地使用,所以在本文中主要讨论在备份中 相似文献

The Citizen Disaster Communication Assessment (CDCA) measures individual disaster communication activities that are intended to help communities cope across all phases of a disaster. Using the CDCA, this study examined associations among citizen disaster communication, neighborhood belonging, and community resilience using three different samples representing different disaster phases (Pre-event, Event, Post-event). Results indicate that more citizen disaster communication was associated with stronger perceptions of neighborhood belonging and community resilience at the Event and Post-event phases. In terms of specific citizen disaster communication processes that proved important, communication to correct disaster rumors and share stories was associated with greater feelings of belonging. Communication intended to confirm disaster information and tell stories was associated with stronger community resilience perceptions. Overall, results (a) confirm that citizen disaster communication is an important part of the disaster response and recovery ecosystem and (b) offer evidence of concurrent validity for the CDCA. 相似文献

图书事业灾害以灾害主体为标志,可分为国家图书事业灾害与私人图书事业灾害两类。传统的书厄论,仅仅关注宏大叙事,缺乏对图书事业灾害的科学认知。张舜徽突破传统书厄论,认为主观因素是造成图书事业灾害的主要来源。历代图书事业灾害的循环往复,在于科学、民主的图书事业机制的缺失,封建蒙昧以及理想化的民粹热情,以及近代国家的积贫积弱。 相似文献

Disaster marathon was proposed by media communication scholars to differentiate the genre of disaster television broadcasting from media events. However, its theoretical framework is limited by its omission of findings from disaster social science literature, and its lack of examinations of marathons of domestic natural disasters. Using the August 2014 Yunnan (China) Television Station broadcast The Special Report on the August 3 Earthquake in Ludian, Yunnan, we conduct a qualitative content analysis to empirically examine the disaster marathon concept for natural disasters. During the content analysis, three themes emerge: authorities’ command and control, the involvement of armed forces, and convergence of social support. Our case study findings contradict the disaster marathon conceptualization and conclude that the local television coverage following a natural disaster can also be performed as a series of conventional media events and is consistent with the established disaster coverage literature. 相似文献

5.12汶川大地震对灾区图书馆造成了重大损失。根据四川省高校图书馆工作委员会和灾区个体馆应对灾难的具体举措,借鉴国外图书馆界和我国其他行业灾难危机管理的成功经验,有必要建立我国图书馆灾难联盟。图书馆灾难联盟的管理内容包括:危机控制管理、风险评估、危机预防、危机准备、危机反应与灾后恢复。灾难联盟管理中需特别注意危机预案的完整性与可获取性、预案中人事分工的明确性、相关部门横向和纵向的借鉴与协调以及灾后员工的心理干预和关键业务的恢复工作等问题。 相似文献

ABSTRACT This article describes the emergence of disaster information (DI) specialists, with particular focus on their presence in health libraries. Although literature on the subject of disasters and libraries is dominated by accounts of librarians preserving collections and ensuring continuity of library operations following a flood, fire, or other disaster event, the work of DI specialists extends beyond these traditional roles. DI specialists conduct outreach in the community, providing information services to emergency managers and other disaster workers. This article recounts a history of disaster information service in which public librarians served communities during disaster recovery periods, and health librarians became involved in organizational disaster planning activities. DI products from the National Library of Medicine are introduced in addition to federal funding opportunities for DI outreach projects. The development of the Medical Library Association's Disaster Information Specialization Program is presented, and the article shares recommendations for library administrators to encourage DI training for librarians and support the development of outreach services to disaster workers. 相似文献

Disaster Information Specialist Pilot Project: NLM/DIMRC 总被引：1，自引：0，他引：1
Medical librarians have often been overlooked as important contributors to hospital disaster preparedness. Recognizing the importance of medical libraries and their potential in disaster planning and management, the National Library of Medicine (NLM), Disaster Information Management Research Center (DIMRC), formed a pilot Disaster Information Specialist Project. This paper describes the preliminary activities of Bishopric Medical Library's Director, Patricia Reynolds, at Sarasota Memorial Health Care System, as a disaster information specialist in the hospital's disaster planning and preparedness. 相似文献
