SQL> select username,lockwait,status,machine,program from v$session where sid in (select session_id from v$locked_object);
(2)然后使用一下语句查找被死锁的语句
SQL> select sql_text from v$sql where hash_value in
(select sql_hash_value from v$session where sid
in (select session_id from v$locked_object));
(3)再使用以下语句查找被死锁的进程
SQL> SELECT s.username,l.OBJECT_ID,l.SESSION_ID,s.SERIAL#, l.ORACLE_USERNAME, l.OS_USER_NAME,l.PROCESS FROM V$LOCKED_OBJECT l,V$SESSION S WHERE l.SESSION_ID=S.SID;
(4)根据步骤(3)查到的sid、serial#,使用以下语句把死锁的进程kill
SQL>alter system kill session ‘sid,serial’; (其中sid=l.session_id)
