/****** 
Server: any

Checks if there are any open connections, and if there was any recent user activity within a given period of time
in a given (or any) database by a given (or any/any except given) login from a certain group of hosts (or any host)
via a particular (or any) application. 
An error will be raised if the last executed batch occurred earlier than defined in @pThresholdMinutes.
This utility is used for server monitoring. It can be executed periodically in a job 
NOTE: It is assumed that only one instance of uspCheckActivity is executed at a time
