一、异常描述

在centos6.4系统安装oracle_x64_11gR2_database版本,安装至95%进度的时,报出"[INS-20802] Oracle Net Configuration Assistant failed...Cause - The plug-in failed in its perform method Action - Refer to the logs or contact Oracle Support Services. Log File Location /home/oracle/oraInventory/logs/installActions2017-01-19_09-48-38AM.log ",如下图所示

二、解决步骤

1. 根据上面提示找到日志位置/home/oracle/oraInventory/logs/oraInstall2017-01-19_03-11-33PM.err，打开查看

2.从上面异常可以看出正常导致异常时UnknownHostException的问题，可以看出是xwood的host配置问题，操作如下

[oracle@xwood logs]$ hostname@b@xwood @b@[oracle@xwood logs]$ cat /etc/sysconfig/network@b@NETWORKING=yes@b@HOSTNAME=xoms@b@GATEWAY=192.168.1.211@b@[oracle@xoms logs]$ hostname@b@xwood @b@[oracle@xoms logs]$ cat /etc/hosts@b@127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4@b@::1         localhost localhost.localdomain localhost6 localhost6.localdomain6@b@[oracle@xoms logs]$ vi /etc/hosts@b@127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4@b@::1         localhost localhost.localdomain localhost6 localhost6.localdomain6@b@127.0.0.1   xwood

3.重新安装，问题解决了
