Oracle XE - Just can't login after install
提问by vmassuchetto
That sounds really stupid.
这听起来真的很愚蠢。
On Lubuntu 10.10, I did:
在 Lubuntu 10.10 上，我做了：
echo "deb http://oss.oracle.com/debian unstable main non-free" >> /etc/apt/sources.list
apt-get update ; apt-get install oracle-xe
That brings me Oracle XE 10.2.0.1. And then:
这给我带来了 Oracle XE 10.2.0.1。进而：
/etc/init.d/oracle-xe configure
Everything looks ok, including the password prompt and so. After that, I go to http://127.0.0.1:port/apex, and when I try to login with the username "SYSTEM", and the password I just typed. I get a "Invalid Login Credentials" error.
一切看起来都不错，包括密码提示等等。之后，我转到http://127.0.0.1:port/apex，当我尝试使用用户名“SYSTEM”和刚刚输入的密码登录时。我收到“无效的登录凭据”错误。
I also tried:
我也试过：
sqlplus /nolog
CONNECT
[ .. login and password .. ]
ERROR:
ORA-01017: invalid username/password; logon denied
Setting the environment variables also don't help.
设置环境变量也无济于事。
sh oracle_env.sh
Well.. I just don't know what's happening. I repeated this procedure trying to find peculiar things, but always got the same results. Also tried some other users as "SYS". useless...
嗯..我只是不知道发生了什么。我重复这个过程试图找到奇怪的东西，但总是得到相同的结果。还尝试了一些其他用户作为“SYS”。无用...
Thanks in advance.
提前致谢。

Exactly the same is happening to me in CentOS 5. With user SYSTEM or SYS, just after install and configure I cannot log in.
我在 CentOS 5 中也发生了完全相同的情况。使用 SYSTEM 或 SYS 用户，在安装和配置后我无法登录。

Yes, make sure the pw is >= 8 characters in length. It won't complain when setting on less than 8, but you won't be able to login ! With >= 8 in length, a successful login !!
是的，确保密码长度 >= 8 个字符。设置小于8就不会报错，但是你将无法登录！长度>=8，登录成功！！

Check whether Oracle is running before trying log in
在尝试登录之前检查 Oracle 是否正在运行
/etc/init.d/oracle-xe start(Should be run as root).
/etc/init.d/oracle-xe start（应该以 root 身份运行）。
Then in sql terminal try log in.
然后在sql终端尝试登录。
connect / as sysdba
connect / as sysdba
