Oracle 11gR2 netca 无法启动 报错 默认主机名导致

是由于默认的主机名导致的，修改2处

NETWORKING=yes

HOSTNAME=hotDB11g

GATEWAY=192.168.1.1

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost hotDB11g

再执行

hostname hotDB11g

让oracle用户退出重新登录就可以正常启动netca了。
