在使用shutdown immediate关闭数据库时hang住,查看alert 日志,遭遇了SHUTDOWN: Active processes prevent shutdown operation。

在使用shutdown immediate关闭数据库时hang住,查看alert 日志,遭遇了SHUTDOWN: Active processes prevent shutdown operation。也即是说有一些活动进程阻止了当前的shutdown操作。咦,数据库是测试数据库啥也没有干,也没有配置db console,还有活动进程阻止呢?

1、情景再现

SQL> select * from v$version where rownum

BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

SQL> @comm_sess_users;    ---->查看当前连接的session

nstance    SID Serial ID    Status    Oracle User    O/S User        O/S PID Session Program              Terminal            Machine

SQL> host;                ---->使用host切换到os提示符下
[oracle@linux3 ~]$ sqlplus / as sysdba      ----->再次登陆到sqlplus

SQL> @comm_sess_users;                      ----->下面的查询可以看到Terminal显示为同一个终端, 都为sys用户, sid 139 为ACTIVE

2、分析与解决
      从上面的情形来看,是由于之前的session没有断开,而后又使用了host切换到OS提示符下,导致数据库无法正常关闭。
      通过进一步的测试,,如果是多个非sys用户登录则不存在此现象。
      Oracle对此给出的说明是这不是一个Oracle bug,而是使用了一个非正常的数据库关闭顺序。
      建议先断开所有连接再关闭数据库,如先关闭db control,具体见下面的Oracle 文档及示例。
