果然革命的道路是曲折的,前两天刚搞定SQL > startup的毛病,今天又出问题了。
在linux系统中用Oracle帐号执行DBCA或其他JAVA图形界面程序时,报错:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: :0.0
查了一下解决办法如下:
用root登陆,在#提示符后输入:
xhost local:oracle non-network local connections being added to access control list
敲回车运行后出现(这是我的 centOS 4 的结果,其他系统可能有不同):
non-network local connections being added to access control list
xhost: bad hostname "non-network"
xhost: bad hostname "local"
xhost: bad hostname "connections"
xhost: bad hostname "being"
xhost: bad hostname "added"
xhost: bad hostname "to"
xhost: bad hostname "access"
xhost: bad hostname "control"
xhost: bad hostname "list"
此时再 su - oracle 切换到Oracle用户执行图形界面任务就可以了(我的用户名是oracle)。
PostScripts:
man xhost中有这样一段
A complete name has the syntax ‘‘family:name’’ where the families are as follows:
inet Internet host (IPv4)
inet6 Internet host (IPv6)
dnet DECnet host
nis Secure RPC network name
krb Kerberos V5 principal
local contains only one name, the empty string
si Server Interpreted
其中local那一行就是用来解决同一台机器的不同用户访问X的问题的。
