有关Oracle sqlplus的连接问题

在win7上运行oracle10g时，可能要以管理员权限运行。还有可能有其他问题，如：

ERRORORA-01017invalid usernamepassword

SQL> conn / as sysdba SQL> alter user SCOTT account unlock identified by tiger;

User altered.

SQL> select username,account_status from dba_users where username='SCOTT'; USERNAME                       ACCOUNT_STATUS ------------------------------ -------------------------------- SCOTT                                OPEN

SQL> conn scott/tiger Connected.

SQL> select * from tab;
