Oracle 11g預設使用者名,密碼解鎖

1.  安裝時選擇的自動安裝，由於時間久遠忘記使用者名稱、密碼了，導致現在試了幾個預設的使用者名稱密碼後（表格中附帶預設使用者名及密碼），都提示無效的使用者名稱、密碼，終於在試了下dbsnmp/dbsnmp，提示被鎖；
2.用sqlplus/as sysdba登入，提示
3.
SQL> alter user dbsnmp account unlock;

User altered.

SQL> alter user dbsnmp identified by dbsnmp;

User altered.
4.[LongKe@Fedora10 ~]$ sqlplus dbsnmp/dbsnmp;
