Unable to telnet Port 5500 RRS feed

  • Question

  • Hi:

    I am running Windows 10. I installed Oracle 12c and the Oracle Enterprise Manager can be accessed at https://localhost:5500/em.

    When I tried to open EM with the url, I get a "cannot load page" error.

    When I tried "telnet localhost 5500", I get an error message.

    I have added a new inbound rule to the firewall and added TCP Port 5500. Even after this, I am not able to telnet.

    Any ideas?

  • Hi,

    In advance, sorry if I misunderstand what you want to do.

    I'm afraid TCP port 5500 is not for Telnet.

  • Actually, since I was having trouble accessing Oracle Enterprise Manager using the link, https://localhost:5500/em, I was checking if I can telnet as the first step of understanding the issue.

    Thanks for letting me know that this port cannot be telnet into.

    So, back to my original question. Even though I have created an inbound rule on the firewall to open Port 5500, I am not able to access this link. Any ideas?

  • Hi,

    I have no experience of Oracle Enterprise Manage.

    Please refer to the following article. I hope this would be helpful.
    Accessing the Oracle Enterprise Manager Database Control

    This says:
    "For example, if you installed the database on a host computer named comp42, and the installer indicated that your Enterprise Manager Console HTTP port number is 5500 (also recorded in the $ORACLE_HOME/install/portlist.ini file), enter the following URL:

    Please check what your host name is.

  • search or ask at forums.oracle.com. Microsoft can help you as far as providing you a telnet client and a browser, but you can easily use third party telnet client or browser to prove that it is the oracle installation that is not working.

  • Check whether you should be using http rather than https. Using https requires a server certificate and it seems unlikely that you'd have been granted one for "localhost".
