Deconfig dbcontrol when oracle has been patched

Hi!

I need to Delete DB Control Repository.
I work with oracle 10g r2


And this is the errors:
xdb02.lazzaro.xtel.it_SID
xdb02.lazzaro.xtel.it_SID.upgrade (my collegue applied a path one month ago. I didn't work here).

May I use this command?


emca -deconfig dbcontrol db

Or is this better?

Remove the following directories from your filesystem:
/

My question:
Should I delete both direcory?
xdb02.lazzaro.xtel.it_SID
xdb02.lazzaro.xtel.it_SID.upgrade

/oc4j/j2ee/OC4J_DBConsole__

NOTE:
On Windows you also need to delete the DB Console service:
- run regedit
- navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
- locate the OracleDBConsole entry and delete it
