listener not registered dbca dbconsole 11g filegroup12.jar missing CompEMdbconsole.pm not found

I made a mistake, file win32_11gR2_database_2of2.zip was not extracted correctly I think.
So I missed a lot of filegroup.jar which was reported during the installation...;-)

So not noting this, I tried to create a database with dbca, all went ok except the dbconsole went wrong.
The errors I received where misleading :
1. Listener is not up or database service is not registered
2. CompEMdbconsole.pm not found.

By extracting the win32_11gR2_database_2of2.zip . Create a new database.
Configured with netca a listener2 on port 1526.
sqlplus / as sysdba
SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.101
)(PORT=1526))'
SQL> /

Then I run PLEASE NOTE THE USE OF paramname oracle_hostname:
D:\app\Gebruiker\product\11.2.0\dbhome_2>emca -config dbcontrol db -paramname or
acle_hostname:localhost
