Orace 12c: Enterprise Manager URL

I installed 12c on a Windows server, and it did not create a shortcut for EM URL.

Enterprise Manager (EM) URL is in following format

http://<servername>:<portname>/em
or
https://<servername>:<portname>/em

You can figure out the port name using following SQL

Run as Sys

select dbms_xdb.getHttpPort() http_port , dbms_xdb_config.getHttpsPort() https_port
from dual

Once you know the port number, you can easily access EM
