<span style="font-family: Times New Roman; font-size: 18px;">1、等数据库访问连接数下降用户再登录<br>
2、sqlplus “/ as sysdba”登陆后</span>

<span style="font-family: Times New Roman; font-size: 18px;"> shutdown abort<br>
3、ps -ef|grep ora_dbw0_$ORACLE_SID </span>

<span style="font-family: Times New Roman; font-size: 18px;"> kill -9 pid<br>
