Oracle 监听器无法启动（TNS-12537，TNS-12560，TNS-00507）

Oracle 监听器无法启动（TNS-12537，TNS-12560，TNS-00507）

oracle启动监听报错，，提示 连接中断

[oracle@localhost ~]$ lsnrctl start

Starting /opt/oracle/11g/bin/tnslsnr: please wait...

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

这样一般是主机名不对，观察监听状态，监听主机名为 localhost:

[oracle@localhost ~]$ lsnrctl status

查看主机名，发现/etc/hosts内localhost只想多个地址，引发监听冲突

[root@localhost ~]# cat /etc/hosts
127.0.0.1  localhost.domain localhost
10.4.40.70  localhost

修改主机名：

1 hostname

查看详情

hostname oracle

2 /etc/hosts

127.0.0.1 localhost localhost.domain
192.168.0.1 oracle

3 /etc/sysconfig/network

hostname = oracle

再次启动,成功

[oracle@oracle ~]$ lsnrctl start
