查看锁表进程SQL语句
1SELECT S.SID SESSION_ID, S.USERNAME, DECODE(LMODE,0 ,' None ' ,1 ,' Null ' ,2 ,' Row-S (SS) ' ,3 ,' Row-X (SX) ' , 4 ,' Share ' ,5 ,' S/Row-X (SSX) ' , 6 ,' Exclusive ' , TO_CHAR(LMODE)) MODE_HELD, DECODE(REQUEST,0 ,' None ' ,1 ,' Null ' ,2 ,' Row-S (SS) ' ,3 ,' Row-X (SX) ' ,4 ,' Share ' ,5 ,' S/Row-X (SSX) ' ,6 ,' Exclusive ' , TO_CHAR(REQUEST)) MODE_REQUESTED, O.OWNER || ' .

OBJECT_ID执行上记SQL语句,可以查寻到数据库中的锁的情报.SESSION_ID, USERNAME,MODE_HELD,MODE_REQUESTED, OBJECT_NAME, LOCK_TYPE, LOCK_ID分别是 拥有锁的SESSION_ID,拥有锁的USERNAME,锁的执行模式MODE_HELD,锁的请求MODE_REQUESTED,锁所在的数据库对象名,锁的类型,锁的ID2、查看锁表进程SQL语句1：select sess.sid, sess.serial#, lo.oracle_username, lo.os_user_name, ao.object_name, lo.locked_mode from v$locked_object lo, dba_objects ao, v$session sesswhere ao.object_id = lo.object_id and lo.session_id = sess.sid;查看锁表进程SQL语句2：select * from v$session t1, v$locked_object t2 where t1.sid = t2.SESSION_ID;杀掉锁表进程：如有記錄則表示有lock，記錄下SID和serial# ，將記錄的ID替換下面的738,1429，即可解除LOCKalter system kill session '738,1429';
