    Unanswered: "VTO-4400: no database has been discovered" error

    hi all,

    i get this error when i try to launh the DBA studio or when i am in the Oracle Enterprise Manager and i try to connect to DBA through it (I am on WinXP/Oracle 8.1.6).

    the following are installed and are started:

    1. OracleServiceOUCIDL
    2. OracleOraHome81TNSListener
    3. OracleOraHome81ManagementServer
    4. OracleOraHome81DataGatherer
    5. OracleOraHome81Agent

    also i've created a Database through the Database Configuration Assistant, as well as a database repository and i've set up the management server on my machine to use the above mentioned repository. i am able to successfuly login to Oracle Enterprise Manager, but the only two nodes i can discover are "localhost" and my machine name (which is the name for the management server i suppose). i can not discover my database for some reason.

    i have this in my listener.ora file:

    # LISTENER.ORA Network Configuration File: C:\Oracle\Ora81\NETWORK\ADMIN\listener.ora
    # Generated by Oracle configuration tools.

    LISTENER =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = ORCL))
    )
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = oucidl.[domain name])
    (SID_NAME = oucidl)
    )
    )

    this is my tnsnames.ora file:

    # TNSNAMES.ORA Network Configuration File: C:\Oracle\Ora81\NETWORK\ADMIN\tnsnames.ora
    # Generated by Oracle configuration tools.

    OUCIDL_DB =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = IPC)(Key = ORCL))
    )
    (CONNECT_DATA =
    (SERVICE_NAME = oucidl.[domain name])
    )
    )

    i created the service name OUCIDL_DB through Net8 Assistant. it listens to the Oracle service "OracleServiceOUCIDL" via the listener "OracleOraHome81TNSListener".

    any ideas?
    thanks.
