bq. but wanted to know whether the order of activation should be A1, A2, A3 
itself and not based on the ordering policy for the recovered apps, Thoughts ?
It should be based on the ordering policy only. At this stage, all 3 
applications A1,A2 and A3 are in same level of position. So activation should 
be based on the ordering policy implementation. In specific to priority, always 
highest priority application should be activated first.

> Currently, same ordering policy is used for pending applications and active 
> applications. When priority is configured for an applications, during

> low priority job was submitted and running state. 
> This causes low priority job in starvation after recovery
