CentOS6.5 静默安装Oracle 11g过程中提示：Exception in thread “main” java.lang.NoClassDefFoundError

原来是系统中设置了DISPLAY环境变量,执行：

[oracle@qa26 database]$ ./runInstaller -silent -responseFile /usr/local/oracle/response/db_install.rsp -ignorePrereq

正在启动 Oracle Universal Installer...

检查临时空间: 必须大于 120 MB。 实际为 34078 MB 通过

检查交换空间: 必须大于 150 MB。 实际为 3951 MB 通过

准备从以下地址启动 Oracle Universal Installer /tmp/OraInstall2017-04-20_03-14-19PM. 请稍候...[oracle@qa26 database]$ Exception in thread "main" java.lang.NoClassDefFoundError

原来是系统中设置了DISPLAY环境变量

执行：

unset DISPLAY

然后再执行runInstaller.sh，执行成功
