Building a backup admin server.....need urgent support

Question

Scenario :
Box (Machine) A has admin server and few manager servers for domain “test”. And few managed server on box B. Managed server of box A and box B are currently handled through admin server on box A. Also node manager is configured to start and stop the servers of box A and box B.
Now in case, box A goes down physically. I want to have one back up admin server on box C,through which I can handle the managed server on box B.
For this I take steps:
Step1
Keep a frequent back of below mentioned folder on box C from box A.
1.     wlsHome \user_projects\domains\<domain name>\config
2.     wls home\user_projects\domains\<domain name>\servers\AdminServer\data\ldap
3.     wls home\user_projects\domains\<domain name>\security
Ref :http://e-docs.bea.com/wls/docs100/server_start/failures.html
Step2
Before starting the admin server on box C I change the admin listen port in config.xml to the hostname or IP of box C.
Step3
For node manager.
On box B, I need to point node manager to admin server to the box C.
1.     Edit startup. Properties in the <domain name>/server/<servername>. In each server folder.
2.     Need to uninstall and install again node manager server to listen the request from different host as by default it listen from localhost.
Ref : http://e-docs.bea.com/wls/docs103/nodemgr/starting_nodemgr.html
“By default, Node Manager listens only from the local host. If you want Node Manager to accept commands from remote systems, you must uninstall the default Node Manager service, then reinstall it to listen on a non-localhost listen address. See Reconfigure Startup Service for Windows Installations.”
I tried these steps but not working. Can any help me out . Am I missing any steps or going in wrong direction for my goal. Is there any alternative way to do this ???
Waiting for a response.

Answer 1

Creo que los pasos 1 y 2 esta bien, pero el paso 3 no es parte de la configuración/procedimiento para alcanzar el objetivo, no obstante, si es necesario y debió haberse aplicado anteriormente. Otra cosa más, no estoy seguro de los cambios que estas haciendo en el paso 3 > 1. "Edit startup. Properties in the <domain name>/server/<servername>. In each server folder.", ¿podrías especificar los cambios que estas aplicando?
¿Porque dices que no funciona?, ¿Cuales son los errores que obtienes?
Steps 1 and 2 are fine, I think step 3 is not part of the configuration/procedure to reach the goal, however, this is necesary and should have been applied previously. One more thing, I'm not sure the changes you are doing in step 3> 1. "Edit startup. Properties in the <domain name>/ server/<servername>. In each server folder.", Could you specify the changes you are applying?
Why do you say It doesn't works?, what are the errors you get?
