Two user accounts are automatically created when Oracle Database is installed:
■ SYS (default password: CHANGE_ON_INSTALL)
■ SYSTEM (default password: MANAGER)
Create at least one additional administrative user and grant to that user an appropriate
administrative role to use when performing daily administrative tasks. Do not use SYS
and SYSTEM for these purposes.
数据库管理员用户名称
安装Oracle时 , sys 与 system默认安装 . 在日常的管理任务中 , 推荐创建另外一个管理员用户
并且赋予适当的角色来执行这些任务
