  • ORA14452: attempt to create, alter or drop an index on temporary table already in use

    今天,同事突然让我创建一个索引,说他创建不上。我拿过来一看,语句很 简单:create index IDX_AQ_NEFILTER on AQ_NEFILTER (INT_ID);。可是一执行就报错。错误信息:

    ORA-14452: attempt to create, alter or drop an index on temporary table already in use

    经查,该错误的解释为:

    Cause: An attempt was made to create, alter or drop an index on temporary table which is already in use.

    Action: All the sessions using the session-specific temporary table have to truncate table and all the transactions using transaction specific temporary table have to end their transactions.

    因为表AQ_NEFILTER 为临时表,而且有其他session正在使用。

    处理步骤:

    1、先从user_objects中查询到该表的object_id:

    select object_id from user_objects where object_name=upper('aq_nefilter');

    2、根据查到的object_id知道使用该表的session:

    select * from v$lock where id1=&object_id;

    3、在从v$session视图中查到该session的SID和SERIAL#:

    select * from v$session where sid=181;

    4、杀掉这些进程:


    alter system kill session '1591,35646';

    5、重新创建索引(4,5两步一定要快,否则,刚结束一个session,又有新的session使用该表了):

    create index IDX_AQ_NEFILTER on AQ_NEFILTER (INT_ID);

    至此,已经创建成功。不过,这个过程中我有个疑问,v$lock 视图中的id1字段是什么意思?和user_objects 视图中的object_id字段是对应的么?哪位看过了给解释下?
