TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
Linux Error: 32: Broken pipe
原因:listener.log文件超过2G
解决方法:清空日志文件
[oracle@chicago ~]$ cd $ORACLE_HOME/network/log

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
