Dispatcher port

Hi all,

I have a basic doubt.

We can have message server port of our choice.Now the question is whether we can block the dispatcher ports and just allow message server port for the users to login. Users get the info from message server about the server info but will it use dispatcher port thats my doubt.

Hello,

GUI users initially connect to the message server (on the sapmsSID port) if their SAPLOGON entry refers to a logon group rather than to a specific server. However, once the message server has selected an instance based on its load-balancing stats and connected the GUI session to that instance, all communication between the GUI and the application server flows via the dispatcher port (sapdp##); the message server does not intervene in this. It follows that the dispatcher ports cannot be blocked to end users.

Regards,

Mark
