-## UCPSample.java: 
-Universal Connection Pool (UCP) is a client side connection pool. UCP 
-furnishes a rich set of features to support scalability in single database
-instance as well as built-in features to support high-availability and 
-scalability in RAC and Active Data Guard environments.  UCP along with RAC,
-RAC One and ADG is a tested and certified combination for handling database
-failovers.  Refer to this sample for using UCP and setting UCP properties
-such as `minPoolSize`, `maxPoolSize`, etc.
-
-## UCPWithTimeoutProperties.java:
-UCP furnishes a set of TimeOut properties which can be used to tune 
-performance. The sample demonstrates using some of UCP's important Timeout
-properties, such as `InactivityTimeout`, `AbandonedConnectionTimeout`, 
-`TimeToLiveTimeout`, and `connectionWaitTimeout`.  Each one of the UCP timeout
-property can be run independently. Refer to the sample for more details. 
-
-## UCPWebSessionAffinitySample.java:
-Web-Session Affinity is a scalability feature of UCP in RAC and Active Data 
-Guard environment which attempts to allocate connections from the same RAC 
-instance during the life of a Web application.  UCP tries to do a best try 
-effort, but, there is no guarantee to get a connection to the same instance. 
-UCP Web-Session Affinity is used in applications which expect short lived 
-connections to any database instance. 
-
-## UCPConnectionLabelingSample.java:
-Connection Labelling allows applications to set custom states ("labels") 
-then retrieve connections based on these pre-set states thereby avoiding the
-cost of resetting these states. The sample uses `applyConnectionLabel()` to
-apply a connection label and retrieves a connection using `getConnection(label)` 
-by specifying the created label. 
-
-## UCPConnectionHarvestingSample.java:
-UCP's Connection Harvesting allows UCP to pro-actively reclaim borrowed 
-connections based on pool requirements at run-time, while still giving 
-applications control over which borrowed connections should not be reclaimed. 
-The sample uses `registerConnectionHarvestingCallback` to register a connection 
-harvesting callback. 
- 
-## UCPWithDRCPSample.java:
-Database Resident Connection Pool (DRCP) is the server side connection pool. 
-DRCP should be used in a scenario when there are a number of middle tiers but 
-the number of active connections is fairly less than the number of open 
-connections.
-DRCP when used along with and Universal Connection Pool(UCP) as the client 
-side connection pool improves the performance.  The sample shows UCP with DRCP
-in action. The purpose of the client-side pooling mechanism is to maintain the
-connections to Connection Broker. Client-side connection pools must attach and
-detach connections to the connection broker through `attachServerConnection()`
-and `detachServerConnection()`. DRCP should be used in a scenario when there are
-a number of middle tiers but the number of active connections is fairly less
-than the number of open connections. 
- 
 ## DRCPSample.java:
 DRCP can be used with or without a client side connection pool. 
 Either UCP or any other third party connection pool (eg., C3P0) can be used as
 client side pool. Note that, when UCP is used, it takes care of attaching and 
 releasing server connections. There is no need to explicitly call 
 `attachServerConnection()`/`detachServerConnection()` with UCP.
