I am using Oracle 18c XE on CentOS 7. The database installed successfully but not able to bring it online to my hostname. what I did is:

Added port 5500 in firewall:

firewall-cmd --permanent --add-port=550/tcp
firewall-cmd --reload

edited sqlplus as:

SQL> exec dbms_xdb.sethttpport(5500)
PL/SQL procedure successfully completed.

SQL> EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
PL/SQL procedure successfully completed.

Then trying to access as: https://linux.domain.com:5500/em

[root@linux ~]# lsof -i :5500
COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
tnslsnr 18295 oracle   16u  IPv6 864455      0t0  TCP *:fcp-addr-srvr1 (LISTEN)

When I check in ping.eu the port 5500 is closed

Best Regards

The problem was this part:

SQL> exec dbms_xdb.sethttpport(5500)
PL/SQL procedure successfully completed.

I configured 5500 on HTTP port but was trying to access it on HTTPS
