Decoupled from Agent: There are no agents currently associated with the application. This is a normal state. When the Connection Concentrator is enabled, there is no dedicated coordinator agent, so an application can be decoupled on the coordinator partition. In non-concentrator environments, an application cannot be decoupled on the coordinator partition as there will always be a dedicated coordinator agent .

1) even if concentrator is not enable in partition environment can application status be decoupled.

2) Online stats was running in partition environment from some reason, wanted to stopped i mean was trying to force off it was not getting forced off, with same user other agent was in decoupled stat after forcing tht the online stats also got forced off.
