TNS-12547: TNS:lost contact 监听无法起动

原创 Linux操作系统 作者:longqidong 时间:2012-04-01 15:29:06 0 删除 编辑
今天做测试,把主机名给改了,同时把 127.0.0.1  localhost 也去掉了,然后死后启动不了监听
 报错信息如下:
TNS-12547: TNS:lost contact
TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
Linux Error: 104: Connection reset by peer

[oracle@test ~]$ lsnrctl start

所以,不要盲目的把 127.0.0.1 localhost  删除掉
 
修改/etc/hosts,修改后如下
[oracle@test ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
192.168.109.200 test.hehe.com test
重新启动listner,OK.
[oracle@test ~]$ lsnrctl start
