OEM创建出错

      数据库环境：Oracle 11gR2  ASM单实例  系统环境： liunx5.5 64位

    今天我在用Oracle11G创建一个ASM单实例环境时候，在dbca创建数据库快要完毕后，弹出一个错误提示框。

Database connection through listener failed. Fix the error and run EM Configuration Assistant again.Some of the possible reasons may be:1) Listener port 1158 provided is incorrect. Provide the correct port.2) Listener is not up. Start the Listener.3) Database service ora11g is not registered with listener. Register the database service.4) Listener is up on physical host and ORACLE_HOSTNAME environment variable is set to virtual host. Unset ORACLE_HOSTNAME environment variable.5) Listener is up on virtual host. Set environment variable ORACLE_HOSTNAME=<virtual host>.6) /etc/hosts does not have correct entry for hostname.

     使得我的OEM没有创建成功，后来根据问题框里面的提示，发现ORACLE_HOSTNAME没有配置好，在配置好以后，重新创建OEM。

     重新创建完成，这个时候要5分钟以上，大家要耐心等待。
