最近在Vmware虚拟机中装了CentOS5+Oracle11gR2，刚装完的时候，可以通过https://192.168.80.11:1158/em访问企业管理器。
后来我修改了虚拟机的主机名称，之后就访问不了企业管理器，端口也被自动改成了5500，然后用5500端口同样也访问不了。
数据库也重启了，操作系统也重启，都没用。[oracle@ora11gr2 oracle]$ cat /u01/oracle/install/portlist.ini
Enterprise Manager Console HTTP 端口 (orcl) = 5500
Enterprise Manager 代理端口 (orcl) = 3938[oracle@ora11gr2 oracle]$ emctl status dbconsole
