共有三种锁表模式:
共享模式(in share mode)
共享更新模式(in share update mode)
排他锁模式(in exclusive mode)
锁表实例: //以排他锁模式锁定tRun表 lock table tRun in exclusive mode
2,查看某个表被锁定
查看被锁定的表: select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id
3,查询sid及serial#
查询sid及serial# select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time
4,删除锁
删除锁表: //其中,159为sid;107为serial# alter system kill session ‘159,107‘
Oracle锁表及解锁
