今天开始学习Oracle 10g，遇到的问题。

1.Oracle 10g 默认的用户名，sysman。密码是安装Oracle 刚开始输入的。
2.用户EM启动数据库时遇到：RemoteOperationException: ERROR: wrong password for user：

    解决方法如下：

1. Go to "Control Panel" -> "Administrative Tools" -> "Local Security Policy."
2. Within "Local Policies", go to "user Right Assignment."
3. Add the user to "Logon as a Batch Job."

例如：如果是administrator.右键点击 logon as batch job,属性，把administrator,加进去即可。
