在Oracle 11G R2裏啓用示例帳戶scott

Oracle裏，默認有個示例帳戶scott。不過在oracle11g r2裏，默認是被禁用了。直接登的話，會得到如下情形。

SQL> conn scott/tiger
ERROR:
ORA-28000: the account is locked

該賬戶現在默認是被鎖定狀態。下面簡單說下如何啓用它。

1，以sysdba進入sqlplus

$ /u01/app/oracle/product/11.2.0/dbhome_1/bin/sqlplus "/as sysdba"

2，解鎖scott 帳戶

SQL> alter user scott account unlock ;

3，修改密碼。第一次登入的時候，會提示密碼已經過去。這時候輸入新的密碼。

SQL> conn scott/tiger;
ERROR:
ORA-28001: the password has expired

Changing password for scott
New password:
Retype new password:
Password changed
Connected.

4，訪問EMP表。scott裏有個表EMP，裝了一些示例數據。

SQL> desc emp;
Name                                      Null?    Type
----------------------------------------- -------- ----------------------------
EMPNO                                     NOT NULL NUMBER(4)
ENAME                                              VARCHAR2(10)
JOB                                                VARCHAR2(9)
MGR                                                NUMBER(4)
HIREDATE                                           DATE
SAL                                                NUMBER(7,2)
COMM                                               NUMBER(7,2)
