Instead of creating and opening new connections for each and every request we have the connections in a connection pool.But what happens when the number requests exceeds the pool size limit.Will any exception is thrown? If so then how we have to handle such situation.Please reply.
Most of the times the connection pool object would have this documented. Most of the time I suspect they wait put you in wait with some timeout. All of this is configurable. Most of the times the max required connection can be safely set. If not most connection pool allow you to set maxConnection to no limit.
P.S - When I say connectionPool I mean a DataBase Connection Pool.
