centos系统安装oracle_x64_11gR2_database版本,在执行./runInstaller命令后,抛出"No protocol specified..Exception in thread "main" java.lang.NoClassDefFoundError.."异常,具体如下所示

二、解决步骤

1. 切换root账号,如下所示

[oracle@xoms database]$ su  root@b@Password:

2.执行命令xhost +,如下所示

[root@xoms database]# xhost +@b@access control disabled, clients can connect from any host

3.再切换oracle继续安装,问题解决了
