redhatserver5中监听器启动不起来-优快云博客

本文讨论了在使用RedHat Enterprise Linux Server 5.2与Oracle Database 10g时，监听器启动失败的问题。通过修改/etc/hosts文件中的IPV6地址配置为IPV4本地回环地址，成功解决了TNS错误。

本机上sqlplus "/as sysdba"是可以进入数据库的，在启动监听器时出现如下情况：

[oracle@btasetl log]$ lsnrctl start

TNS-12537: TNS:connection closed
TNS-12560: TNSrotocol adapter error
TNS-00507: Connection closed
Linux Error: 29: Illegal seek

上网上找了一下，说是有可能是/etc/hosts文件的问题，我按照方法试了后还是不行

$ORACLE_HOME/network/log/listener.log文件内容如下：
