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
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 06-AUG-2014 20:02:16
Copyright (c) 1991, 2009, Oracle. All rights reserved.
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

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 111: Connection refused
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 111: Connection refused
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
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
