[cx-oracle-users] acquire() vs. connect(): DRCP cclass and purity params

[Jim F. <jim...@sb...>]

I see the two params cclass and purity in the documentation for connect(), but not for acquire().  Acquire() accepts the two params but doesn't do anything with them (I checked the C cource code).
 
So should I be using be using connect() instead of acquire()?  If I use connect(), do I need to pass in credentials and DSN, since I already passed them when creating SessionPool?
