Your server not allow x-windows from :0.0
try

$ su - root

# xhost +

allow aceeslist

and then dbca again from "oracle" user...

that just about OS to help you dbca...

About EM not running, you should check log files at /u01/app/oracle/product/10.2.0/db_1/server1.example.com_orcl/sysman/log/ PATH

and investigate the problem.

Or re config

$ emctl stop dbconsole
$ emca -deconfig dbcontrol db

When all else fails & you are desperate for information, you could always Read The Fine Manual.

http://www.oracle.com/pls/db102/portal.portal_db?selected=3#index-ENT

or just utilize online help

Usage:: 
   Oracle Enterprise Manager 10g Database Control commands:
       emctl start| stop| status| setpasswd dbconsole
       emctl status dbconsole [-secure]
       emctl secure <options>

       emctl set ssl test|off|on em
       emctl set ldap <host> <port> <user dn> <user pwd> <context dn>
emctl blackout options can be listed by typing "emctl blackout"
emctl config options can be listed by typing "emctl config"
emctl secure options can be listed by typing "emctl secure"
emctl ilint  options can be listed by typing "emctl ilint"
emctl deploy  options can be listed by typing "emctl deploy"

Ok found out that there was a bug with OEM 2.2, that was the reason i kept getting this error "ORA-12640: Authentication adapter initialization failed", one bug of many aparently.

The work around for this is to set the SQLNET.AUTHENTICATION_SERVICES= (NONE) in the sqlnet.ora file

Managed to get access to metalink and found at least 38 separate pacthes for 8.1.7. The one I downloaded was 115mb.

Also found out the reason why I kept getting the VNI-2015 error with OEM 2.0.4 was not because the credentials were wrong but because it has a bug that does not allow exporting or importing.

Managed to get past the VNI-2015 in OEM 2.2 by Instead of creating an OS user logon for the domain I created one for just the server and then granted "log on as a batch job".

Hope this is some help to any poor sole that gets stuck on the same problem.
