Abstract


Disaster , including earthquakes, typhoons , terrorist incidents , itself are low probability event , but once the impact of the information system is fatal . How to protect data security , disaster and maintain business continuity has become one of the important areas of information systems research , 911 events more urgency and importance . Shanghai public transportation card central clearing system (CCHS) remote disaster recovery system , for example, discussed in detail the specific application of disaster recovery technology and the CCHS disaster recovery in the development of a the CCHS remote disaster recovery system . This paper describes the basic needs of the CCHS remote disaster recovery , respectively, from the three aspects of the business , data , network analysis . This paper describes the design of the CCHS remote disaster recovery system , designed with HP MC / SERVICE GUARD and storage area network (SAN) technology as the core of the local disaster recovery system , ORACLE DATA GUARD and socket communication programming techniques combined CCHS data remote data replication and synchronization system , as the main medium of SDH circuit design , more economical disaster recovery network architecture . This paper describes the implementation of a the CCHS remote disaster recovery system . Finally, through the disaster recovery switch , upcoming business switch to remote disaster recovery system run to test the actual effect of the CCHS remote disaster recovery reached . The significance of this paper is that comprehensive analysis of remote disaster recovery system technology , developed an application ORACLE DATA GUARD technology and applications combining remote data replication scheme , can effectively guarantee system to switch when data integrity , and improve the the security of the system and the ability to resist risks .
