在這裡我們要介紹的是Oracle如何解鎖用戶的方法，對於Oracle如何解鎖用戶，一般我們都是試用默認密碼來進行。希望本文對大家有所幫助。
1. 安裝時選擇的自動安裝，由於時間久遠忘記用戶名、密碼了，導致現在試了幾個默認的用戶名密碼後（表格中附帶默認用戶名及密碼），都提示無效的用戶名、密碼，終於在試了下dbsnmp/dbsnmp，提示被鎖；
2. 在CMD中啟動SQLPLUS；用sqlplus/as sysdba登錄，Oracle如何解鎖用戶提示
連接到:
Oracle Database
3. 執行ALTER USER DBSNMP ACCOUNT UNLOCK；
4. 從新用SQL/PLUS登錄，設置用戶名、密碼；
注：由於剛才解鎖的用戶名是DBSNMP，所以這裡設置的用戶名也是DBSNMP
