plsql 执行insert操作，未提交事务，plsql失去连接导致锁表的解决方法

一、登录oracle数据库

su - oracle

sqlplus /nolog

conn / as sysdba

二、查询被锁的表

select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;

三、查询被锁的session和serial#

 select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;

四、.删除锁住的session和serial#

 alter system kill session '14,3061';
