步骤1：用以下SQL查看进程列表，判断出被锁定的表
SELECT dob.OBJECT_NAME Table_Name,lo.SESSION_ID||', '||vss.SERIAL# 删除号,
lo.locked_mode,lo.SESSION_ID, vss.SERIAL#,vss.action Action,vss.osuser OSUSER, vss.LOGON_TIME,
vss.process AP_PID, VPS.SPID DB_PID ,vss.*
From v$locked_object lo, dba_objects dob, v$session vss, V$PROCESS VPS
Where lo.OBJECT_ID = dob.OBJECT_ID
and lo.SESSION_ID = vss.SID
AND VSS.paddr = VPS.addr
order by 2,3,DOB.object_name
lo.locked_mode,lo.SESSION_ID, vss.SERIAL#,vss.action Action,vss.osuser OSUSER, vss.LOGON_TIME,
vss.process AP_PID, VPS.SPID DB_PID ,vss.*
From v$locked_object lo, dba_objects dob, v$session vss, V$PROCESS VPS
Where lo.OBJECT_ID = dob.OBJECT_ID
and lo.SESSION_ID = vss.SID
AND VSS.paddr = VPS.addr
order by 2,3,DOB.object_name
--查找被锁表
步骤2 删除进程，如之前的“删除号”查找出的结果为“286, 2184”，则运行以下SQL
ALTER system kill session '286, 2184'
删除后不会马上生效一般,要过一会
