1.找出数据库的serial#,以备杀死: select t2.username,t2.sid,t2.serial#,t2.logon_time from v$locked_object t1,v$session t2 where t1.session_id=t2.sid order by t2.logon_time; 2.杀死该session alter system kill session 'sid,serial#';…

1.查看数据库锁,诊断锁的来源及类型: select object_id,session_id,locked_mode from v$locked_object; 或者用以下命令: select b.owner,b.object_name,l.session_id,l.locked_mode from v$locked_object l, dba_objects b where b.object_id=l.object_idSELECT lpad(' ',decode(l.xidusn ,0,3…

数据库操作语句的分类 DDL:数据库模式定义语言,关键字:create DML:数据操纵语言,关键字:Insert.delete.update DCL:数据库控制语言 ,关键字:grant.remove DQL:数据库查询语言,关键字:select oracle表在什么情况下会被锁住 DML锁又可以分为,行锁.表锁.死锁 行锁:当事务执行数据库插入.更新.删除操作时,该事务自动获得操作表中操作行的排它锁. 表级锁:当事务获得行锁后,此事务也将自动获得该行的表锁(共享锁),以防止其它事务进行DDL…
