1、以下代码可以查看是否被锁表：select a.object_name,b.session_id,c.serial#,c.program,c.username,c.command,c.machine,c.lockwaitfrom all_objects a,v$locked_object b,v$session c where a.object_id=b.object_id and c.sid=b.session_id;
2、查询锁表原因：select l.session_id sid, s.serial#, l.locked_mode, l.oracle_username, s.user#, l.os_user_name, s.machine, s.terminal, a.sql_text, a.action
3、接上：from v$sqlarea a, v$session s, v$locked_object lwhere l.session_id = s.sid and s.prev_sql_addr = a.addressorder by sid, s.serial#;
4、解锁方法：alter system kill session ’146′; –146为锁住的进程号，即spid。
5、查看被锁的表：select p.spid,c.object_name,b.session_id,b.oracle_username,b.os_user_name from v$process p,v$session a, v$locked_object b,all_objects c where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id
6、以上就是oracle查看锁表的方法，以及一些相关信息，看过之后如果觉得有帮助可以在下面给小编点个赞~
