Question

Oracle新手。我在CentOS 6.8上成功安装了Oracle DB。我创建了两个数据库：

ORCL
AVDB

AVDB＆＃39;有一些用户。数据库。我希望将用户放入AVDB数据库。但即使我作为SYS AS SYSDBA用户连接，我的权限错误也不足。我甚至无法使用sys用户创建用户。

但是，当我连接到不同用户的同一个数据库（我试图删除的那个是avuser）时，我能够创建用户。

[oracle@via7was ~]$ sqlplus sys as sysdba

Answer 1

首先，确定保管库是否处于活动状态：

 SQL> SELECT PARAMETER, VALUE FROM V$OPTION WHERE PARAMETER = 'Oracle Database Vault';

        PARAMETER
        ----------------------------------------------------------------
        VALUE
        ----------------------------------------------------------------
        Oracle Database Vault
        TRUE

然后以数据库所有者身份连接并禁用保管库：

SQL> conn avuser
        Enter password:
        Connected.
        SQL> EXEC DVSYS.DBMS_MACADM.DISABLE_DV;

        PL/SQL procedure successfully completed.

以SYSDBA身份连接并重新启动数据库：

SQL> conn sys as sysdba
Enter password:
Connected.
SQL> SHUTDOWN IMMEDIATE
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.

通过以SYSDBA：
连接来删除用户

SQL> conn sys as sysdba
    Enter password:
    Connected.
    SQL> drop user avuser cascade;
    drop user avuser cascade
    *
    ERROR at line 1:
    ORA-01940: cannot drop a user that is currently connected

如果您收到上述错误，请找出该用户的活动会话被摔掉并杀死他们：

SQL> SELECT s.sid, s.serial#, s.status, p.spid FROM v$session s, v$process p WHERE s.username = 'AVUSER' AND p.addr(+) = s.paddr;

               SID    SERIAL# STATUS   SPID
        ---------- ---------- -------- ------------------------
                17      48252 INACTIVE 45579

        SQL> ALTER SYSTEM KILL SESSION '17,48252';

        System altered.

        SQL> drop user avuser cascade;

        User dropped.

注意：始终建议重新启用保险库以确保安全性活动结束后的原因。

SYSDBA无法删除Oracle 12.1.0.2中的用户
