Restricting Concurrent users on a particular BSP Application

We are having an appraisals link in the PM section of the portal which runs the HAP_DOCUMENT BSP application. We have to restrict the number of concurrent users accesing this application at the same time to about 600 so that the server will not crash...Is there a way by which i can find out the no of users accesing a partcular BSP application concurrently??

The first thing that comes to mind is the use a Logon Group (Transaction SMLG). You can restrict the use of Logon Group via the number of connected users. You can also attach a logon group to a service node (Transaction SICF). If you create a new logon group, just for this application and attach it to the service node, you might be able to acomplish what you are looking for. However I don't know how nice the message back to the user will be.

Hi Thomas,

I create a logon group using SMLG. I inserted the value 1 in the users field. Then i attached this logon group to a service node of a particular BSP Application. Then I activated the Service Node. But when i run the application twice at the same time for two users, it still doesnt give any error message and allows the application to be run for both the users. Am I missing anything in this??

Appearently my interpretation of how Logon Groups work don't match up to their actual sophistication.

They use this number of users only as a gage to load balance between mutliple app servers. It never uses this amount as a limiting factor.

Sorry if I led you down an incorrect path. It seemed promissing. However you could at least use this approach to limit the load to a single app server. You could then configure the maximum number of concurrent connections in the ICM on this app server. However this probably only works if you are willing to dedicate a single app server to this single application.
