Re: [Javtools-poolmngr] Suggested course of action

[Isabelle M. <met...@pa...>]

Personally, I think that for the first release the requirements should be :

(1) provide pooled connections to users
(2) the connections in one pool can be either all the same type of JDBC
connection (same connection URL, username/password) or they can be different
type. An other alternative would be to have more than one pool, and each
pool is homogeneous.
(3) the user protocol is : borrow, use, return.
(4) we can set some policies as to how long a connection may be in use
(difficult in real life, because a very busy servlet might hold on to the
connection for a long time)
(5) the pool is self-regulating : grows when connection demand is intensive,
shrinks when less demand
(6) configuration thru XML config file

IMO these are sufficient for a first release.
