    oracle中的用户很多,也很令初学者费解.
    oracle中的帐户分为两类:一类是必需的帐户,一类是存储各种应用的帐户

    用户名 密码 描述
    ANONYMOUS ANONYMOUS 访问http的匿名用户帐户
    CTXSYS CTXSYS interMedia Text用户
    DBSNMP DBSNMP 目录集成平台用户
    EXFSYS EXFSYS 表达式过滤器用户
    MDDATA MDDATA oracle空间数据帐户
    MDSYS MDSYS oracle空间数据媒体管理员
    MGMT_VIEW MGMT_VIEW  
    OLAPSYS MANGER 用于创建olap元数据
    ORDPLUGINS ORDPLUGINS oracle ineterMedia,video用户
    ORDSYS ORDSYS image管理员
    OUTLN OUTLN 拥有connect和resource角色
    SCOTT Tiger 样例帐户
    SI_INFORMATN_SCHEMA   静止图像浏览帐户
    SYS 用户指定 数据库管理帐户
    SYSMAN OEM_TEMP 企业管理器帐户
    SYSTEM 用户指定 数据库管理帐户
    WK_TEST WK_TEST 同wksys
    WKPROXY   代理帐户
    WKSYS WKSYS 同wk_test
    WMSYS WMSYS 工作空间管理帐户
    XDB CHANGE_ON_INSTALL xml db帐户
         
         
         

    默认情况下oracle指对sys,system,dbsnmp,sysman,mgmt_view5个帐户进行了解锁,如果希望其它用户也能登录需要手工进行解锁

    show user  显示当前登录系统的用户名
    select username,account_status,expiry_date from dba_user; 查看用户状态
    alter user outln account unlock; 解锁帐户
    grant connect 帖哦outln identified by 123; 用户授权
