    Hi,

    You only have tcp dispatchers but tcps xdb config by the look of it - that might be part of the problem.

    Hold on - looking again - you don;t use sqlplus to connect to the xdb service - you use http/https

    just use dunk rather than dunkxdb in your sqlplus session.

    or try https://localhost:5500 in a browser and see what you get

    Cheers,

    Rich

    Please run

    select dbms_xdb.gethttpport

    from dual;

    If the outcome is

    0

    you need to run

    exec dbms_xdb.sethttpport(8080)  -- or some other high value

    I posted this problem because I could not log into EM Express on the new 12c database that I created.  I am following the steps in the Oracel doc "Troubleshooting Why EM Express is not Working (Doc ID 1604062.1)".  I have done steps 1-4.  Step 5 is "5- Connect to the XDB service as the SYSTEM user".  It showes that you should be able to connect to XDB database using system id:

    SQL> conn system/[email protected]

    Connected.

    This is the step that is not working for me.

    I was asked if this is limited by PROCESSES value and I do not think it is:

    [email protected]> show parameter processes

    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    aq_tm_processes                      integer     1
    db_writer_processes                  integer     1
    gcs_server_processes                 integer     0
    global_txn_processes                 integer     1
    job_queue_processes                  integer     1000
    log_archive_max_processes            integer     4
    processes                            integer     450

    I was asked to try https.  I used this command in both IE and Chrome and could not connect to EM Express

    https://localhost:5500/em

    IE gave this error message:

    This page can't be displayed

    • Make sure the web address https://localhost:5500 is correct.
    • Look for the page with your search engine.
    • Refresh the page in a few minutes.
    • Make sure TLS and SSL protocols are enabled. Go to Tools > Internet Options > Advanced > Settings > Security

    I was asked to check the http port.  Here is the result

    [email protected]> select dbms_xdb.gethttpport from dual;

    GETHTTPPORT
    -----------
              0

    The HTTPS port for EM Express (XDBO is setup:

    [email protected]> SELECT dbms_xdb_config.gethttpsport() FROM dual;

    DBMS_XDB_CONFIG.GETHTTPSPORT()
    ------------------------------
                              5500

    Any other suggestion would be appreciated.
