监听启动报TNS-12537、TNS-12560错误

环境说明：OS：CentOS 6.5DB：Oracle 11.2.0.3问题：数据库启动监听的时候，报如下错误：[oracle@localhost admin]$ lsnrctl startConnecting to （DESCRIPTION=（ADDRESS=（PROTOCOL=IPC）（KEY=EXTPROC1521）））STATUS of the LISTENER------------------------Alias LISTENERVersion TNSLSNR for Linux: Version 11.2.0.1.0 - ProductionStart Date 27-NOV-2015 08:44:40Uptime 0 days 0 hr. 0 min. 18 secTrace Level offSecurity ON: Local OS AuthenticationSNMP OFFListener Parameter File /ora01/app/oracle/product/11.2.0/db_01/network/admin/listener.oraListener Log File /ora01/app/oracle/diag/tnslsnr/dbtest001/listener/alert/log.xmlListening Endpoints Summary... （DESCRIPTION=（ADDRESS=（PROTOCOL=ipc）（KEY=EXTPROC1521）））（DESCRIPTION=（ADDRESS=（PROTOCOL=tcp）（HOST= ）（PORT=1521）））TNS-12537: TNS:connection closedTNS-12560: TNS:protocol adapter errorTNS-00507: Connection closedLinux Error: 29: Illegal seek解决方法：1、修改计主机名，安装系统的时候默认的主机名为localhost，这个主机名进行解析的时候会出现很多诡异的问题，强烈建议大家记得修改主机名；2、修改/etc/hosts 的文件[root@localhost tmp]# cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.1.100 dbtest001 经过以上操作后，再次启动监听[oracle@dbtest001 ~]$ lsnrctl startLSNRCTL for Linux: Version 11.2.0.1.0 - Production on 27-NOV-2015 09:21:55Copyright （c） 1991, 2009, Oracle.
