> The connections  in Connection Pooling Service become invalid for several 
> reasons : session timeout, firewalls block idle connections, outages of 
> backend server, etc.
> In the current niif releases this connections rest in the pool as good  but 
> when the user use one of them is triggered an errror  for the backend 
> database. 
> Ex: org.netezza.error.NzSQLException: FATAL 1:  Connection Terminated - 
> session timeout exceeded
> With this improvement we pretend periodicaly to test all the connections , 
> drop the invalid ,create new ones and  mantain all the pool healthy.
