linux下oracle 用户名和密码是什么

一定有设置用户名和密码的地方，只是你没注意；

如果没设置，就是默认的用户名和密码，如下：

sys/change_on_install

system/manager

在CRT中进入oracle --连接sqlplus 按照下面写完代码直接复制进去回车就行了

---建立用户代码为：CREATE USER "用户名字" PROFILE "DEFAULT" IDENTIFIED BY "密码" DEFAULT TABLESPACE "指定表空间名字" TEMPORARY TABLESPACE "临时表空间" ACCOUNT UNLOCK

---赋权
