Background
I am attempting to install Oracle 12c on CentOS 7 (deployed as a Hyper-V virtual machine) as outlined by this installation guide.
Problem
Everything with my installation goes well except for the Oracle Database Configuration Assistant.
The installation provides me with the following messages:
ACTION: Specify a free port
Action - Refer to the logs or contact Oracle Support Services.
Debuging Information and Actions Attempted
When I run a tail on the error log I get the following messages related to the installation:
INFO: ... GenericInternalPlugIn: getting configAssistantParmas.
INFO: ... GenericInternalPlugIn: checking secretArguments.
INFO: ... GenericInternalPlugIn: starting read loop.
INFO: Read: [FATAL] [DBT-06103] The port (5,500) is already in use.

Running sudo netstat -anp | grep 550
returns the results below:
unix 3 [ ] STREAM CONNECTED 37299 5502/gnome-pty-help
unix 3 [ ] STREAM CONNECTED 37283 5501/gconfd-2
unix 3 [ ] STREAM CONNECTED 37287 5501/gconfd-2
To try and remedy the problem, prior to subsequent fresh installation attempts I commented out the following statements in my services file as displayed through running cat /etc/services | grep 550

I have additionally attempted to do step 5.1 of the installation guide prior to the installation with no success.

Question
Why am I getting an error that the port isn't open when it doesn't seem like anything is using that port and how to I remedy this issue?
Is there are method that can be used to change the port from 5500 to a complete different one? I'm just trying to get a dummy database installed for the HR schema.

I encountered this exact error and found it was my mistake. Spent whole day for that.
Please, carefully observe your
/etc/hostname
and/etc/hosts
. In my case, "oem" was put in/etc/hosts
and "eom" was in/etc/hostname
.
