ORA-12518错误

無限追云

各位兄弟好，请教个问题

环境：
OS:Windows 2003    db Oracle10g

是个档案查询系统，20多个人使用。这几天最近老是出 ORA-12518错误。

processes为150，session为20多。这个session数也不高呀。

我重启了数据库和监听，这时应用系统的账号也登陆不进去了。

监听的状态是正常的，conn sys/xxx@XXX  as sysdba也能正常登陆

下面是监听的部分日志：

谢谢了

lsnrctl status listener_name
lsnrctl service listener_name

alert.log

方便的话，做个trace

应该是超过了SESSION才报这个错的 检测下 看下trace  

加大SESSION 跟process
