Priority groups and Session persistence

Guys,

 

I have two nodes behind my VS and using PGA less than 1 for two nodes. So active and passive. I am not using any peristence profile as i want the higher priority group to service requests if they flap anytiome.

 

But in this way when we login to the application it times me out immediately. Where as when i use source persistence i am able to login and work normaly.

 

Any idea?

    You are getting confused with 2 different features.

     

    1. PGA (Priority Group Activation) is a feature where you can assign priorities for a set of servers to handle traffic & put logic to goto next set of servers when a min required servers are not present.

       

    2. Session Persistence : This holds your user preferences like username & pwds.

       

    So its obvious when you apply persistence, it will not time out immediately.
