Oracle解锁，解决“ora00054：资源正忙”错误

一.处理步骤：
--1.获取被锁对象的session_id
SELECT session_id FROM v$locked_object;
--2.通过session_id获取v$session的sid和serial#
SELECT sid, serial#, username, osuser FROM v$session where sid = session_id;
--3.终止相关进程。
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
---------- ---------- ------------------------------ ------------------------------
141 41464 VC VC02\Admin

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

SQL> select session_id from v$locked_object;
SESSION_ID
