In the secure file on this server on the rscd line change the port setting.
In the secure file on any system that talks to this server, you need to add an override for this host to use this port. (copy the ‘default’ line, replace default w/ host=yourserver iirc)
I believe you will have to restart the agent after the changes done to secure file
I made the changes on the 'special' server and can see the agent running on the modified port. By 'any system that talks to this server' you mean i need to modify the secure file for the application servers ? so in addition to the 'default' line i would need one that looks like :
default:port=4750:<SSL and NSH proxy settings here the same as default>
specialhostnamehere:port=SPECIAL_PORT:<SSL and NSH proxy settings here the same as default>
You may need to restart the appserver service to pickup the change.
