Oracle RMAN failing to accept connections on port 5501

Posted on 2012-09-05
Last Modified: 2012-09-13
We have an in-house oracle applications that we use the RMAN  web interface to manage a monthly tasks deleteing all obsolete and expired backups.

we access the site using  http://<server_name>/5501/em

However this is now giving me an error when it has worked perfectly before.  When i diagnose the issue I get this error message.

The device or resource (<server_name>) is not set up to accept connections on port "5501".

Just wondering if there is anything I can check to aid my diagnosis of the issue.

    I assume you are using dbconsole and not grid control?

    Make sure it is started:  emctl start dbconsole

    Thanks for your reply. I started out with your thread and saw this command on an OTN forum as a starting point

    So i set the oracle_sid to the production environment

    and ran emctl status dbconsole
     to check the status of the console assuming that if it was stopped or started it would let me know.

    I got this response from running the command:

    OC4J Configuration issue. H:\oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole <servername.domain name_dbname> not

    That's fine but the 'status' isn't what I asked for.  Try to start it and post any errors.

    When you say that it used to work and now doesn't:  What changed on the system?

    I ran the command to start the console but got exactly the same error as i posted above.  As far as any changes are concerned, none that i'm aware of as last month I managed to use the console perfectly.

    Is the machine using DHCP?  Oracle likes a static IP address.  Try installing the Loopback adapter and making it the first network connection available.

    You might need to recreate dbconsole.

    Thanks for all of your input on this. I'm a bit of a novice when it comes to oracle maintenance so you will have to forgive my stupidity. I decided to go back to the original thread and to determine if the console had started.  first time round i executed a bat file which sets up my environment variables for the porduction database and includes the SET ORACLE_SID command which i think was my first mistake. and this is when i got th error i reported in the second part of the thread

    looking at it with fresh eyes i ran this sequence:

    C:\set Oracle_SID=<prod db>
    then ran
    emctl start dbconsole
    and it said the control was already running.
    I got this message.

     ( see attached file).  I'm guessing this is a good thing as the console is running. Does it matter where the start dbconsole command is run from? When i'm on the server and enter the address i get a windows enhanced security window pop up so i have added the web site to a trusted site. still with the same result.

    confirmed service had started had to do a restart of the server for another unrelated issue and checked the URL again and it worked.
