Oracle解鎖，解決“ora00054：資源正忙”錯誤
一.處理步驟：
--1.獲取被鎖對象的session_id
SELECT session_id FROM v$locked_object;
--2.通過session_id獲取v$session的sid和serial#
SELECT sid, serial#, username, osuser FROM v$session where sid = session_id;
--3.終止相關進程。
ALTER SYSTEM KILL SESSION 'sid,serial';
二.示例：
SQL> select session_id from v$locked_object;
SESSION_ID
----------
141
SQL> SELECT sid, serial#, username, osuser FROM v$session where sid = 141;
SID SERIAL# USERNAME OSUSER
---------- ---------- ------------------------------ ------------------------------

SQL> ALTER SYSTEM KILL SESSION '141,41464';

SQL> select session_id from v$locked_object;
