招数一:
1. 查看被锁的表: 2. select p.spid,c.object_name,b.session_id,b.oracle_username,b.os_user_name from v$process p,v$session a, v$locked_object b,all_objects c where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id 3. 4. 解锁: 5. alter system kill session '146';(其中146为锁住的进程号) 招数二: 1. SELECT sn.username, m.SID,sn.SERIAL#, m.TYPE, 2. DECODE (m.lmode, 3. 0, 'None', 4. 1, 'Null', 5. 2, 'Row Share', 6. 3, 'Row Excl.', 7. 4, 'Share', 8. 5, 'S/Row Excl.', 9. 6, 'Exclusive', 10. lmode, LTRIM (TO_CHAR (lmode, '990')) 11. ) lmode, 12. DECODE (m.request, 13. 0, 'None', 14. 1, 'Null', 15. 2, 'Row Share', 16. 3, 'Row Excl.', 17. 4, 'Share', 18. 5, 'S/Row Excl.', 19. 6, 'Exclusive', 20. request, LTRIM (TO_CHAR (m.request, '990')) 21. ) request, 22. m.id1, m.id2 23. FROM v$session sn, v$lock m 24. WHERE (sn.SID = m.SID AND m.request != 0) --存在锁请求,即被阻塞 25. OR ( sn.SID = m.SID --不存在锁请求,但是锁定的对象被其他会话请求锁定 26. AND m.request = 0 27. AND lmode != 4 28. AND (id1, id2) IN ( 29. SELECT s.id1, s.id2 30. FROM v$lock s 31. WHERE request != 0 AND s.id1 = m.id1 32. AND s.id2 = m.id2) 33. ) 34. ORDER BY id1, id2, m.request; 35. 36. alter system kill session '91'; 37. alter system kill session '144,633'; 38. alter system kill session '91,21'; 39. alter system kill session '112,5772'; 2010年3月15日 20:44
