如何知道Oracle 10g Ex的用户名和密码？

Question

实际上，我忘记了Oracle 10g Ex的用户名和密码。有没有办法找到它们？

Answer 1

以属于'dba'[unix]或'ora_dba'[windows]组的用户（通常是'oracle'）或Windows机器上的管理员身份登录数据库服务器。然后，您将能够以SYS用户身份登录Oracle，并通过执行以下操作更改SYSTEM密码

SELECT * FROM AlertsTbl
WHERE Email IN (
SELECT Email
FROM AlertsTbl
GROUP BY Email
HAVING COUNT(*) = 1)

接下来，我们需要更改SYS的密码：

$ sqlplus "/ as sysdba"
SQL*Plus: Release 9.2.0.1.0 - Production on Mon Apr 5 15:32:09 2004

Connected to:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production

SQL> show user

USER is "SYS"

SQL> passw system
Changing password for system
New password:
Retype new password:
Password changed
SQL> quit

您现在应该可以使用您输入的密码登录SYS和SYSTEM用户。
