Hi RickMy main concern with Session Sharing is I always thought Published Applications would be launched from the least loaded PS4 server. This isn't the case as all subsequent applications are run from the same Server hosting the first application. Because I cannot control the amount of applications a user can open, Im concerned users may open every application and use excess server resources. My servers occasionally use close to 80% of the total memory (4Gb). I have a farm of servers and have around 400 concurrent users.
You mentioned I can control the amount of apps a user runs from the 1 Host. Where do I find this setting? All my users run their apps from the same Host (ie the Host that lauched App1 due to session sharing) so this may ease my burden a little knowing user A can open x amount of apps from any one host.
Regards Ang

You can restrict the number of times a user can log on, or the number of instances of a specific published application that they can run. However while you could restrict the total number of published aplications a user can run on any one server, I'm not aware of any way you could make that work by selectively turning off session sharing when an application number limit has been reached. About the only way you'd get something different is if you siloed your applications so that different servers had different apps. But that would end up being slower in terms of application startup time so it wouldn't win you any kudos from your users. Pardon my asking, but what is the reason for your objection to session sharing?

Makes sense. I did a quick google on it and an article stated it uses the same connection for opening multiple applications from the same host. I want to restrict all users to opening 8 applications across the farm. I enabled this setting in farm properties but it didn't appear to work (I could open more than 8 apps). Is this due to session sharing?. Will opening 10 applications appear as 1 application as it uses the same session hence the restriction not working or do I have an issue?
