oracle 11g默认用户名、密码解锁 以及安装后重启黑屏问题[指南] 安装时选择的自劢安装,由于时间久远忘记用户名、密码了,导致现在试了几个默认的用户名密码後，格中附带默认用户名及密码，,都提示无效的用户名、密码,终于在试了下dbsnmp/dbsnmp,提示被锁; 首先启动sqlplus 输入用户名:sqlplus / as sysdba 密码空缺 如果用户被锁定，记得加上 SQL> alter user dbsnmp account unlock; User altered. 然后修改密码 SQL> alter user dbsnmp identified by dbsnmp; User altered. 现在就可以用用户名:dbsnmp 密码:dbsnmp登录了。 Oracle 10g 默认安装带来的用户名/密码 Username Password Description See Also CTXSYS CTXSYS The Oracle Text account Oracle Text Reference The account used by the Management Agent component of Oracle Enterprise Manager Grid Oracle Enterprise Manager to Control Installation and Basic DBSNMP DBSNMP monitor and manage the database Configuration LBACSYS LBACSYS The Oracle Label Security Oracle Label Security administrator account Administrator's Guide The schema used by Oracle Spatial Oracle Spatial User's Guide and MDDATA MDDATA for storing Geocoder and router data Reference The Oracle Spatial and Oracle interMedia Locator administrator Oracle Spatial User's Guide and MDSYS MDSYS account Reference Oracle Data Mining Administrator's Guide DMSYS DMSYS The Oracle Data Mining account.
