安装oracle软件后，必须要先配置listener才能dbca建库，但是netca却报下面的错误。

Oracle Net Services Configuration:

#

# An unexpected error has been detected by HotSpot VirtualMachine:

是由于默认的主机名导致的，修改2处

[oracle@jc11g ~]$ cat/etc/sysconfig/network

NETWORKING=yes

HOSTNAME=test11g

GATEWAY=192.168.1.254

 

[oracle@jc11g ~]$ cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1              localhost.localdomain localhost test11g

再执行

hostname test11g

让oracle用户退出重新登录就可以正常启动netca了
