昨晚下班的时候，我准备关闭本机的虚拟机上的ORACLE数据库后准备下班，但是由于我SecureCRT开了多个窗口，结果一不小心，疏忽之下在一个生产服务器上执行了shutdown immediate命令，大概过了6到7秒，发现该命令还没有响应，我才发现我这个命令执行错了服务器。一惊之下，想都没有想直接CTRL+C想中断这个操作。 如下所示：
SQL> shutdown immeidate;
SP2-0717: illegal SHUTDOWN option
SQL> shutdown immediate;
^C^C^C^C^C
ORA-01013: user requested cancel of current operation
于是我在另外一个窗口里面查看了一下告警日志文件，发现数据库已经关闭了一些进程。大体情况如下所示

于是立马查看数据库的状态，看看是否正常，结果如下所示，出现了ORA-00604、ORA-00376、ORA-01110等错误。
SQL> SQL> SQL> select status from v$instance;
select status from v$instance
*
ERROR at line 1:

ORA-00376: file 1 cannot be read at this time
ORA-01110: data file 1: '/u01/oradata/SCM2/system01.dbf'
一惊之下，立马退出了会话，重新登录后（当时不怎么冷静，慌忙之下已经不谈定了）

SQL> shutdown immediate;
ORA-24324: service handle not initialized

ORA-01089: immediate shutdown in progress - no operations are permitted
此时告警日志里面有大量的这类错误。
无奈之下，我只能使用shutdown abort命令了，这时候我反而冷静下来。但是居然报ORA-01031: insufficient privileges 错误，立马退出然后重新登录后，将数据库关闭然后重新启动。
SQL> shutdown abort

重新启动后，监控告警日志，发现没有异常出现，逐个检查后发现没有什么问题，一颗悬着的心才淡定下来。不过还是要总结一下：这是一次低级失误，也是印象比较深的一次失误，我之所以要记录下来，一来这也是一个案例，二来要自己谨记于心。整个过程中，发现自己一直不冷静、不谈定。其实本来已经shutdown了数据库，那应该先冷静分析一下，到底是等数据库关闭后重新启动，还是中断这个进程。 本身ORACLE数据库已经关闭了一些进程，如果此时中断shutdown 进程，明显是个不明智的决定。错误的决策导致后面一系列问题的出现，典型的修为不够！ 老大给我的邮件叫我下次应该 relax, calm down and be careful 。 谨记于心。
