查看Oracle中是否有锁表

当执行一条删除或者插入语句删除没几条数据,但是半天没反应,可能是锁表导致,对此表无法进行操作
su - oracle

sqlplus / nolog

conn sys as sysdba

sys

grant connect,resource,dba to TSAMS(用户名);
SELECT * FROM v$lock;
SELECT * FROM v$sqlarea;
SELECT * FROM v$session;
SELECT * FROM v$process ;
SELECT * FROM v$locked_object;
SELECT * FROM all_objects;
SELECT * FROM v$session_wait;

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;

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;
SELECT sid, serial#, username, osuser FROM v$session;

SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,
s.terminal, s.logon_time, l.type
FROM v$session s, v$lock l
WHERE s.sid = l.sid
AND s.username IS NOT NULL
ORDER BY sid;

alter system kill session'210,11562';
