解决OEM打不开的问题
If you go to $ORACLE_HOME/install, you will see the file portlist.ini. If you open this file, you will see one or more entries in the format
Enterprise Manager Console HTTP Port
In my case, my SID, TEST is running on the port 5501, and therefore the following entry appears in ports.ini :
Enterprise Manager Console HTTP Port (TEST) = 5501
In order for this entry to be added automatically, I think you have to use the database configuration assistant (dbca) to create the database.
When I open the following location, http://127.0.0.1:5501/em/, in my browser I can see the enterprise management console for the SID. Similarly, the URL http://127.0.0.1:5500/em/ is the management console for another SID that is running on the same machine.
If you are using Linux, make sure that that 127.0.0.1, or the hostname (in the url) in the portlist.ini file is in the /etc/hosts* file.
