Disable only one application server for CRM Web UI

Maybe this is strange question, but I want to prepare such thing, and I haven't found anything what could help me.

I have four active application servers for CRM, new users which want to work via WEB GUI have link to ASCS instance which is distributing HTTP connections according to SMLG. Some of them have added link to FAVORITE in web browser, so finally lot of people are logging to one instance.

My question is. I would like to disable only one instance from WEB GUI, but if I will disable service in SICF all instances will be unavailable. Is there any possibility to switch off only one instance, so only one link (to one application server) will be unavailable?

Best Regards

Hello Anna,

I believe the best solution here would be to have a SAP WebDispatcher sitting in front of the

CRM application servers. (Good for security as well) Then you can distribute the HTTP requests in a more balanced fashion.

See the following WIKI WebDispatcher

The end users who have the favourite saved will need to update it to the new WebDispatcher URL.

If you want to stick with logon group SMLG then see the following WIKI:

SAP Logon Group

Hello Anna,

It is not possible to disable only one instance for just a specific service (e.g., WEB GUI).

This is because once a request reached a specific instance, that instance will process it.

You could disable the HTTP / HTTPS port(s) of the instance, but this would block the access to all services.

I agree with Oisin, the Web Dispatcher would be the best solution.
