前言

當 Exchange 資料庫使用一段時間後 (視使用者人數及 Mailbox 大小而不同),應該重組 Exchange 資料庫 (.edb) 及資料流 (.stm) 檔案。

為何需要重組 Exchange 資料庫 (.edb) 及資料流 (.stm) 檔案?

  • 有助於增加存取和擷取 Exchange 資料庫 (.edb) 及資料流 (.stm) 的速度
  • 有助於釋放已刪除的使用者信箱空間 (MailBox)
  • 縮小 Exchange 資料庫 (.edb) 及資料流 (.stm) 檔案大小

安裝及設定

如何執行重組 Exchange 資料庫 (.edb) 及資料流 (.stm) 檔案

此例實作環境設定如下:(請尊重 Weithenn 的辛勞!!)
  • Managment.edb 路徑: R:\EXCHSRVR\MDBDATA\Managment.edb
  • Managment.edb 檔案大小: 7.06 GB (重組前)
  • Managment.edb 重組花費時間: 6765.360 seconds
  • Managment.edb 檔案大小: 3.67 GB (重組後)

利用 eseutil 指令執行重組 Exchange 資料庫 (.edb) 及資料流 (.stm) 檔案 (請記得先卸載)

如果執行重組 Exchange 資料庫 (.edb) 及資料流 (.stm) 檔案失敗

此例環境設定如下:(請尊重 Weithenn 的辛勞!!)
