59+ Universal Connection Pool (UCP) is a client side connection pool. UCP
60+ furnishes a rich set of features to support scalability in single database
61+ instance as well as built-in features to support high-availability and
62+ scalability in RAC and Active Data Guard environments. UCP along with RAC,
63+ RAC One and ADG is a tested and certified combination for handling database
64+ failovers. Refer to this sample for using UCP and setting UCP properties
65+ such as ` minPoolSize ` , ` maxPoolSize ` , etc.

69+ Database Resident Connection Pool (DRCP) is the server side connection pool.
70+ DRCP should be used in a scenario when there are a number of middle tiers but
71+ the number of active connections is fairly less than the number of open
72+ connections. DRCP when used along with and Universal Connection Pool(UCP) as the client
73+ side connection pool improves the performance. The sample shows UCP with DRCP
74+ in action. The purpose of the client-side pooling mechanism is to maintain the
75+ connections to Connection Broker. Client-side connection pools must attach and
76+ detach connections to the connection broker through ` attachServerConnection() `
77+ and ` detachServerConnection() ` . DRCP should be used in a scenario when there are
78+ a number of middle tiers but the number of active connections is fairly less
79+ than th number of open connections.
