當執行恢復處理時, websphere application server將獲得對物理恢復日誌文件的排它鎖定,而當websphere application server將日誌的持有權轉給其它服務器時將讓出該鎖定。In non - journaled file systems, file recovery can take hours or days. most file server customers cannot tolerate the downtime associated with non - journaled file systems
而在非日誌文件系統中,文件恢復可能花費幾小時或幾天。大部分文件服務器用戶不能容忍與非日誌文件系統相關的停機時間。To prevent such problems from occurring, websphere application server uses network file locking technology to ensure exclusive access to recovery log files
要避免這樣的危險發生, websphere application server使用網路文件鎖定技術來確保對恢復日誌文件的排它訪問。Oracle online recovery depends a great deal on what is actually lost, for example, losing a group on online redo logs, losing a rollback segment data file, or corrumption of a data file for the system table space
Oracle聯機恢復很大程度上取決于實際丟失了什麼,例如,在聯機重做日誌上丟失了一個組、丟失了回滾段數據文件或者system表空間的數據文件的損壞。Redo log file
恢復日誌文件Scalable and robust, its advantage over non - journaled file systems is its quick restart capability : jfs can restore a file system to a consistent state in a matter of seconds or minutes

在完整恢復模式或大容量日誌恢復模式下,使用文件和文件組備份恢復數據庫時,還需要從一個或多個日誌備份(使用backup log創建)中還原事務日誌。Jfs provides improved structural consistency and recoverability and much faster restart times than non - journaled file systems such as hpfs, ext2, and traditional unix file systems
Jfs提供了改進的結構化一致性和可恢復性,以及比非日誌文件系統(例如: hpfs 、 ext2和傳統unix文件系統)快得多的系統重啟時間。Option, a diagnostic message is printed on the console or to a log file every time the gc runs, including how long it took, the current heap usage, and how much memory was recovered

只有通過轉移到日誌技術,這些文件系統才能避免需要檢查文件系統的所有元數據才能驗證文件系統或將其恢復到一致狀態這一耗時的過程。The recovery time associated with this log - based approach is much faster since the replay utility need only examine the log records produced by recent file system activity rather than examine all file system meta - data
由於重放實用程序只需檢查文件系統最近活動所產生的運行記錄,而不是檢查所有文件系統的元數據,因此,與這種基於日誌的方法相關的文件系統恢復時間要快得多。Recovering from the loss of an unarchived online log file
