If any log is waiting in the redo queue, the mirror server finishes rolling forward the mirror database
如果重做隊列中有任何等待的日誌,則鏡像服務器將完成前滾鏡像數據庫的操作。Force service with possible data loss on the mirror server
在鏡像服務器上進行強制服務(可能造成數據丟失) 。If the entire cluster has problems, you can force service onto the mirror server
如果整個群集出現問題,則可以將服務強制到鏡像服務器中。With five or more cpus, a mirror server distributes its roll forward operations among multiple threads during a failover this is known as parallel redo
如果cpu的數量為五個或更多時,鏡像服務器便會在故障轉移過程中,在多個線程之間分配其前滾操作(稱為「并行重做Failover time for the database depends on how fast the mirror server can roll forward the log in the redo queue, which, in turn, is determined primarily by the system hardware and the current work load
數據庫的故障轉移時間取決于鏡像服務器前滾重做隊列中日誌的速度,此速度反過來主要由系統硬體和當前的工作負荷決定。How the mirror server detects a failure of the principal server depends on whether it is a hard or soft failure
鏡像服務器檢測主體服務器故障的方式取決于故障是硬故障還是軟故障。However, this can cause the principal server to slow down to allow the mirror server to keep up
不過,這會導致主體服務器的速度下降,以便鏡像服務器能夠與其同步。For example, a server instance might initially be the mirror server for two databases
例如,服務器實例最初可能是兩個數據庫的鏡像服務器。However, estimating the potential interruption of service is limited to estimating the time for the mirror server to switch roles after the forced service command is issued
但是,在發出強制服務命令后,估計的潛在服務器中斷時間將限定為估計鏡像服務器切換角色的時間。The performance of the cd image server was evaluated by test the accessing rate of cd data
並且通過測量數據訪問速率對此光盤鏡像服務器的性能進行了評測。While monitoring the redo queue on the mirror server, increase the load on the principal server
當監視鏡像服務器中的重做隊列時,會增加主體服務器中的負荷。There, the mirror server immediately writes the log record to disk as the last record in the redo queue
同時,鏡像服務器立即將日誌記錄寫入磁盤,作為重做隊列中的最新記錄。To achieve synchronous operation for a session, the mirror server must synchronize the mirror database with the principal database
若要實現會話的同步操作,鏡像服務器必須將鏡像數據庫與主體數據庫同步。While the other server instance acts as a hot or warm standby server the mirror server
」 ) ,而另一個服務器實例則充當備用服務器( 「鏡像服務器Describes recommendations for configuring the mirror server, which is only a warm standby server when used with notification services
說明了配置鏡像服務器的建議,用於notification services時,該服務器只是備用服務器。High - performance mode, supports only one form of role switching : forced service with possible data loss, which uses the mirror server as a warm standby server
高性能模式反過來僅支持一種角色切換形式:強制服務(可能丟失數據) ,此服務使用鏡像服務器作為熱備用服務器。The result shows the performance of our cd image server is superior to that of traditional sharing cd devices
實驗數據表明,新型光盤鏡像服務器的性能良好,能夠適應高速、高效共享光盤數據的應用。Based upon the work mentioned above, we deeply researched the linux - based cd image technology. and a practical nas device, modularized cd image server, was implemented. thus the cd data can be shared on network
在上述工作的基礎上,本文深入研究了基於linux系統的光盤鏡像技術,開發了一種實用的nas設備? ?模塊式光盤鏡像服務器,實現了光盤數據的網路共享。In role switching, the mirror server acts as the failover partner
在角色切換中,鏡像服務器充當主體服務器的「故障轉移夥伴Role switching involves transferring the principal role to the mirror server
角色切換涉及將主體角色轉換給鏡像服務器的操作。分享友人
