Analisis High Availability pada Sistem Berbasis Teknologi Oracle Data Guard (Studi Kasus SIA-SAT UKSW)

摘要

. High Availability on Oracle Data Guard-based System (Case Study: SIA-SAT UKSW). SIA-SAT is a subject administration system for UKSW collegian. Database SIA-SAT is backuped by autobackup system, and backup file sent directly to backup server at another building. Until these days, database SIA-SAT system still does not have a secondary database (backup) which can replace main database when failure is happening on main database.Oracle Data Guard System is a technology researched by Oracle to increase availability level on Oracle Database server. Every transaction is saved on main server and duplicated for standby database server. The advantages point of technology is standby database which indirectly becomes a backup server, and standby database can be used for replacing main database.The result of this research is the technology of Oracle Data Guard can increase availability level for a system Oracle Database. This condition can happen because standby database always duplicates data and is ready to replace primary database.
