    Have you set ORACLE_SID?
    Also check Listener.

    It is an environment variable ORACLE_SID being not set.

    On the command prompt, type set and see if it is there. Most likely, it is not there. You can do the following:

    cmd> set ORACLE_SID=mySId

    I have correctly exported the environment variable
    set ORACLE_SID=
    And I receive the same error.

    Just want to make sure, did you do the following

    set ORACLE_SID=


    set ORACLE_SID=yourSIDname

    Also, check if you are getting anything in
    1) Oracle's alert.log file.
    2) Operating system log (MyComputer->Manage->Event Viewer->Application or System)

    I am pretty sure you will find something meaningful there.

    I need to make some tasks:

    1.- I restored the bd from a cold backup,
    2.- The service name no were correctly
    3.- when you finish of restore the database, create the service like:

    oradim -NEW -SID -INTPWD -PFILE

    With that you create the service, and now you can make 2 things:

    a) Start the service that start the database
    b) connect in prompt
    set ORACLE_SID=
    sqlplus /nolog
    connect sys/ as sysdba

    " You are connected to an idle instance"

    And OK, let you have started the DB.

    Thanks for all.
    I wait to be of help.
