I am trying to login into OEM, but getting an error.
vtk1000: Unable to connect to the management server (hostname). please verify that you have entered the correct host name and the status of the Oracle management Server.
Than I tried to check the status of the Oracle Management server.

start -> programs -> Administrative tools -> services.
Double click it ,but I couldn't see any entry for Oracle Management Server .

What does that mean?

    OMS is three tier architecture; do you have an installed OMS?
    Which version of Oracle are you using?

    There are few different products that you can use to manage your database:
    1) Enterprise manager GUI console:

    This only requires you to have an oracle client and a server. (No OMS required)

    2) DB Console: Comes with 10g and can be used to manage 1 database only.

    3) Grid control/OMS: used to manage multiple databases, requires a separate OMS/Grid control server and an intelligent agent running on the databases you manage.

    Thanks for quick response.

    I have Oracle 8i as plus as Oracle 9i , but I'm not sure about the installation of OMS.
    How I can I check it.

    Sounds like you need to start OMS:

    run this command: emctl start oms

    Accepted Solution

    use oemctrl instead of emctl in 8i

    When i entered emctl start oms, got an error:
    'emctl' is not recognized as an internal or external command, operable program or batch file.

    Smurti1: Were you the one who installed this system, or you inherited it from some other DBA ?

    It is possible that you don't have OMS installed, to check that you could startup OUI and look at the installed products.

    You could also do a global find of emctl, generally it is available under $ORACLE_HOME/bin

    dir emct*.* /s

    OMS would have a seperate oracle home as opposed to your database oracle_home.

    I inherited it from some other DBA. when I tried this ---dir emct*.* /s
    got this message---volume in drive C is IBM_PRELOAD
    volume serial number is 9430-5F7D
    file not found

    This means that most probably you don't have OMS installed although there is still a possibility that it is installed on some other host.

    You can either install OMS ( it is somewhat complex process, and managing the management server, takes quite a bit of effort)
    or use some other tools like Enterprise manager GUI to manage your database.
