oracle 安装报错解决办法

1、 Xlib: connection to ":0.0" refused by server 错误解决办法

#xhost +

错误信息如下：

----------

Xlib: connection to ":0.0" refused by server

Xlib: No protocol specified

xhost:  unable to open display ":0.0"

----------

.bash_profile文件添加内容如下：

--------------------------------

ORACLE_BASE=/data/u01/app/oracle

ORACLE_HOME=/data/u01/app/oracle/product/11.2

ORACLE_SID=ecworld

export ORACLE_BASE ORACLE_HOME ORACLE_SID

#export DISPLAY=:0.0    #只要注释掉此行，然后执行xhost + 就不会出现上述错误了。

export EMLOCALHOST=rhlinux

export PATH=$ORACLE_HOME/bin:$PATH

--------------------------

2、 执行netca进行网络配置的时候报错。

信息如下：

------------------

[oracle@localhost database]$ netca 

Oracle Net Services Configuration:

#

# An unexpected error has been detected by HotSpot Virtual Machine:

#

#  SIGSEGV (0xb) at pc=0x00002aaab7a9a9f1, pid=9102, tid=47804837936800

------------------

解决如下：

修改 /etc/hosts    

127.0.0.1               localhost.localdomain localhost  oracle11gr2  #在这行最后添加这个。

然后命令行执行修改主机名的操作

#hostname oracle11gr2

然后再次执行 netca 就可以正常安装配置了。
