环境:
OS:Red Hat Linux As5
DB:10.2.0.1
今天在编辑/etc/hosts文件的时候不小心将127.0.0.1 localhost.localdomain localhost该行去掉了,后来启动监听器的时候报如下错误:
TNS-12537: TNS:connection closed
TNS-12560: TNS:protocol adapter error
TNS-00507: Connection closed
Linux Error: 29: Illegal seek
最后找了下官方文档的说明如下:
This document is being delivered to you via Oracle Support's Rapid Visibility (RaV) Rapid Visibility (RaV) process, and therefore has not been subject to an independent technical review.
The information in this document applies to:
Oracle Net Services - Version: 10.1.0.3
This problem can occur on any platform.
Symptoms
The listener fails to start with the following errors:
TNS-12537: TNS:connection closed
TNS-12560: TNS:protocol adapter error
TNS-00507: Connection closed
Linux Error: 29: Illegal seek
Generic to Unix platforms.
Cause
Wrong syntax in hosts file and also due to the the tnslsnr process was enhanced in
10.1.0.3 to support FAN(Fast Application Notification) via
ONS (Oracle Notification Services). This new code opens a socket open on localhost. Therefore
"localhost" should be defined on the system.
This new code opens a socket open on localhost. Therefore "localhost" should be defined on the
system.
Fix
Change /etc/hosts file to include
127.0.0.1 localhost.localdomain localhost
最后将标红色的行加入到hosts文件,问题解决.
