I'm trying to install Oracle 11gR2 Entreprise Edition but during database creation, I got this Error : 

Environment Variable ORACLE_UNQNAME not defined

And when I tried to lunch 'emctl.bat' From cmd I got this one :

Please set ORACLE_UNQNAME to database unique name.

And to slove this error, I have used this commande : 

set ORACLE_UNQNAME=orcl

To define my Enivronment variable (orcl is the database name) I got this error for the 'emctl' command:

EM Configuration issue. D:\app\product\11.2.0\dbhome_1/Chlebta-PC_orcl not found

So any Help For sloving this issue ?

:\> emctl status dbconsole

Environment variable ORACLE_UNQNAME not defined.
Please set ORACLE_UNQNAME to database unique name

Here is how to set oracle_unqname in Windows. You use a similar "export command" in UNIX/Linux:

C:\>set ORACLE_HOSTNAME=localhost

C:\>set ORACLE_UNQNAME=orcl

C:\>set ORACLE_SID=orcl

C:\>emctl status dbconsole

the best way to set your environment variables is the graphical way :

control panel >  system > advanced system settings > Environment variables

now just click on new and inter the variable name : inter your variable name like ORACLE_UNQNAME and int variable value : inter the value , such as

now for the error of : its seems like your host name "which is the computer name" is : not , check your and make sure of the in there and the host name of the .
