一句话搞定TNS-12537、TNS-12560、TNS-00507、Linux Error:29 错误组合

针对Oracle 10g启动监听器时出现的TNS-12537、TNS-12560、TNS-00507、Linux Error:29 错误组合，在Trouble Shooting的时候不要单独排查某个报错。举个例子，启动我的监听~

[oracle@linux_19 ~]$ lsnrctl start

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 14-AUG-2009 13:46:11

Copyright (c) 1991, 2005, Oracle. All rights reserved.

Starting /oracle/product/10.2.0/bin/tnslsnr: please wait...

TNS-12537: TNS:connection closed

TNS-12560: TNS:protocol adapter error

TNS-00507: Connection closed

Linux Error: 29: Illegal seek

　　这个时候vi /etc/hosts，查看hosts文件。

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 linux_19.xiangyong.com

　　在127.0.0.1对应的主机名后面添加一个“localhost”就可以了！这么做的具体原因不详，摸索ing，欢迎高手来指点！
