换了新版的dbvisualizer 10.0.2发现有改密码的选项
手痒痒想试试
结果失败了
下面是官方说明，简单的说需要Oracle 12c 以后的版本才能支持改密码，
公司版本用的是11g 所以放弃了，没试12c版本，就这样 萨扬娜拉！
Changing an Oracle Password
If your Oracle password has expired, you get a message about this in the Connection Message area for the database connection when you try to connect. For Oracle 12c or later, you can change the password from within DbVisualizer if you use the Oracle Thin JDBC driver (version 12.2 and later):
- Open the Object View tab for the connection if it is not already open,
- Check the Change Password checkbox in the Authentication area,
- Enter the new password in the New Password field,
- Click Connect.
The connection is then established and the password is changed. The Database Password field is updated with the new password automatically.
You can also change the password as described at any time, even if it hasn't expired.
