之一: Oracle数据库操作中,我们有时会用到锁表查询以及解锁和kill进程等操作 (1)锁表查询的代码有以下的形式:select count(*) from v$locked_object;select * from v$locked_object;(2)查看哪个表被锁select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id =
https://blog.csdn.net/a5582ddff/article/details/79566678 MySQL锁表解决方法 一.我的处理过程 1.查进程,主要是查找被锁表的那个进程的ID SHOW PROCESSLIST; 2.kill掉锁表的进程ID KILL 10866;//后面的数字即时进程的ID 网上找了些资料,了解了一下,先分享一下: 二.mysql的锁表问题 SHOW PROCESSLIST查看数据库中表的状态,是否被锁:kill id //杀掉被锁的表====
一.逐条--锁表 (1)查表名 和 sessionidselect b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id; (2)sessionid(sid) .serial# select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$
mysql查看被锁的进程 //查看所有进程show processlist; //查询是否锁表show OPEN TABLES where In_use > 0; //查看被锁住的 SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCKS; //等待锁定 SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCK_WAITS;

查询锁表进程: 1.查询是否锁表 show OPEN TABLES where In_use > 0; 2.查询进程 show processlist 查询到相对应的进程===然后 kill id 补充: 查看正在锁的事务 SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCKS; 查看等待锁的事务 SELECT * FROM INFORMATION_SCHEMA.INNODB_LOCK_WAITS; 分析锁表原因: 参考:htt
背景 在操作Oracle时,多人同时操作oracle数据库的同一张表的时候,经常会造成锁表现象,这时需要手动进行解锁. 步骤 以dba身份登录Oracle数据库(否则用户缺少杀掉进程权限,需要给用户分配权限) sqlplus / as sysdba,如下图 查看被锁住的表进程 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_i
