strings 命令 strings exp 一、描述
最近工作中遇到一個案例，客戶9i數據庫系統，由於主機宕機，主機無法啟動，只有exp的備份文件，在我們不知道表空間名稱和業務用戶的情況下需要對數據進行恢復。
最近工作中遇到一個案例，客戶9i數據庫系統，由於主機宕機，主機無法啟動，只有exp的備份文件，在我們不知道表空間名稱和業務用戶的情況下需要對數據進行恢復。
二、操作
1、找到exp備份文件，要求備份文件不要備份的本地，找一臺備份機。
2、通過strings命令可以得知創建表空間和用戶的腳本。
3、可以按照用戶導入，也可以全庫導入，可以忽略告警
4、不建議使用vi打開幾十G的備份文件。
