ORA-01012: not logged on

ORA-01012: not logged on

一：出现情况：

二：原因分析：

  1 conn / as sysdba 报错ORA-01012: not logged on
  2 
  3 发生原因：关闭数据库是shutdown 后面没有接关闭参数中的任何一个。
  4 
  5 nomal --->所有连接都断开时才能关闭；
  6 
  7 transactional --->等待事务结束后，主动断开连接；
  8 
  9 immediate --->主动断开事务和连接
 10 
 11 abort --->立刻关闭数据库，这个操作是危险的，不会同步数据，不触发检查点，回滚段直接清 空，相当于掉电，每次启动都要实例恢复。
 12 
 13 所以，数据库关闭很慢，这时我一心急，就直接退出了sqlplus,造成Oracle文件被lock,当我再次startup时，操作失败，因为文件依然被锁定状态。报错ORA-01012: not logged on.
 14 
 15 后来重启服务，就可以用了，看了oracle的报错解释，更让我费解。虽然问题解决了，但是生产环境是不能随便down机的，所以，这个问题待续…

三：处理方法

  1 kill oracle 进程 或者关掉oracle
  2 
  3 ps -ef|grep ora_dbw0_$ORACLE_SID
  4 
  5 kill -9 pid
  6 
  7 重新启动oracle
  8 
  9 sqlplus sys as sysdba
 10 
 11 startup;
 12 

  1 [oracle@localhost ~]$ sqlplus / as sysdba;
