oracle 锁表sql查询及解锁

1.锁表sql查询，可查看导致锁表的sql

SELECT L.SESSION_ID SID,
       S.SERIAL#,
       L.LOCKED_MODE,
       L.ORACLE_USERNAME,
       S.USER#,
       L.OS_USER_NAME,
       S.MACHINE,
       S.TERMINAL,
       A.SQL_TEXT,
       A.ACTION
  FROM V$SQLAREA A, V$SESSION S, V$LOCKED_OBJECT L
 WHERE L.SESSION_ID = S.SID
   AND S.PREV_SQL_ADDR = A.ADDRESS
 ORDER BY SID, S.SERIAL#;

2.杀死锁表进程

alter system kill session 'SID,SERIAL#';
