1标题：查询死锁会话id(SESSION_ID)
SELECT p.PID,a.serial#,c.object_name,b.session_id,b.oracle_username,b.os_user_name
FROM v$process p, v$session a, v$locked_object b, all_objects c
WHERE p.addr = a.paddr
AND a.process = b.process
AND c.object_id = b.object_id;
2：查询死锁进程SPID(sid=SESSION_ID)
select * from gv$process
where addr in (
select paddr from gv$session where sid =11324
);
3：虚拟机 kill -9 SPID
等待一会儿再查询步骤1，发现死锁查询会话消除了，证明已经删除掉死锁进程
