By default , when we setup enterprise Manager database console(dbconsole), 1158 port will be configured.

But we can change this port easily using emca utility.

In the below example, we will change the port from 1158 to 7100
1. Check the current dbconsole details:

Currently the port is 1158 . https://prodb:1158/em/console/aboutApplication

2. Invoke emca command as below

./emca –reconfig ports -DBCONTROL_HTTP_PORT

3. Check the status again:

We have successfully changed the http port of the database console.
