Oracle数据库表查看锁以及解锁SQL(很好,很好用)

//查询被锁的表select A.sid, b.serial#,decode(A.type, 'MR', 'Media Recovery', 'RT','Redo Thread', 'UN','User Name', 'TX', 'Transaction', 'TM', 'DML', 'UL', 'PL/SQL User Lock', 'DX', 'Distributed Xaction', 'CF', 'Control File', 'IS', 'Instance State', 'FS', 'File Set', 'IR', 'Instance Recovery', 'ST', 'Disk Space Transaction', 'TS', 'Temp Segment', 'IV', 'Library Cache Invalida-tion', 'LS', 'Log Start or Switch', 'RW', 'Row Wait', 'SQ', 'Sequence Number', 'TE', 'Extend Table', 'TT', 'Temp Table', 'Unknown') LockType, c.object_name, b.username, b.osuser, decode(a.lmode, 0, 'None', 1, 'Null', 2, 'Row-S', 3, 'Row-X', 4, 'Share', 5, 'S/Row-X', 6, 'Exclusive', 'Unknown') LockMode, B.MACHINE,D.SPID from v$lock a,v$session b,all_objects c,V$PROCESS D where a.sid=b.sid and a.type in ('TM','TX') and c.object_id=a.id1 AND B.PADDR=D.ADDR //用于解锁alter system kill session'SID,SERIAL#'
