ORA-00054: 资源正忙，要求指定 NOWAI

问题如下：

SQL> SQLPLUS

.....

SQL> conn sys/sys@192.168.15.8:1521/ORCL as sysdba
Connected to Oracle Database 11g Enterprise Edition Release 11.1.0.6.0

SQL> drop table student2;

drop table student2

ORA-00054: 资源正忙, 但指定以 NOWAIT 方式获取资源, 或者超时失效
=========================================================

解决方法如下：

=========================================================

SQL> select session_id from v$locked_object;

SESSION_ID
----------
       142

SQL> SELECT sid, serial#, username, osuser FROM v$session where sid = 142;

       SID    SERIAL# USERNAME                       OSUSER
---------- ---------- ------------------------------ ------------------------------
       142         38 SCOTT                          LILWEN

SQL> ALTER SYSTEM KILL SESSION '142,38';

System altered

SQL> conn sys/sys@192.168.15.8:1521/ORCL as sysdba
Connected to Oracle Database 11g Enterprise Edition Release 11.1.0.6.0
Connected as scott

SQL> drop table student2;

Table dropped
