主题：部分客户端PL/SQL登陆数据库服务器报：ora-03135；ORA-12543: TNS: 无法连接目标主机；ORA-12543
修改listener的inbound_connect_timeout参数的方法 环境：
aix 5.3 +oracle10g R2 10.2.0.3.0 +rac(主、从)
现象：
1、突然出现部分ip(192.168.10.151)，不能登录oracle，部分ip（192.168.10.50)可登录oracle，不能登录的clients，改成可登录的ip，又可登录；改回原来的IP，还是不能登录oracle。
2、resource_limit=false（default)，改为：resource_limit=true,仍不行。
3、添加sqlnet.ora文件,并添加内容：
sqlnet.expire_time=20
还是不行。
4、查server是否ip及applicatin限制，没有做ip、application限制。
5、server端对oracle instance重启，故障仍在。
6、僵尸的session，也没有。
7、OS serverSID for oracle kill 后，还是不行。
8、tnsping SID均通。tnsping sid 100 均显示ok
9、sessions_highwater=34, 4cpu current_session=27
采用盖老师提供的如下办法方法一:$ lsnrctl LSNRCTL for IBM/AIX RISC System/6000: Version10.2.0.3.0 - Production on 29-OCT-2007 10:00:57 Copyright (c) 1991, 2006, Oracle.All rights reserved.

换IP还是不能成功登录数据库。郁闷！看来他的场景与我这情况不一样。
有人建议做如下测试
telnet ip 1521弹出一个黑白的空窗口。
telnet ip:1521提示23关闭。
