oracle资源正忙，需指定nowait

1.通过此语句查询正在锁定的SESSION_ID:

SELECT distinct  SESSION_ID   FROM   V$LOCKED_OBJECT,USER_OBJECTS
WHERE   V$LOCKED_OBJECT.OBJECT_ID   =   USER_OBJECTS.OBJECT_ID
2.通过第一步查询到的SESSION_ID查询SERIAL#：
622
928
617

SELECT SERIAL# FROM V$SESSION  WHERE SID='622'
3.根据1,2步查询到的SESSION_ID和SERIAL#执行：

ALTER   SYSTEM   KILL   SESSION  '622,315' (48为SESSION_ID的值, 2476为SERIAL#的值)
ALTER   SYSTEM   KILL   SESSION  '143,60'
