Questions about Oracle are best directed to the forums at

DataSource objects were introduced with JDBC 2.0. According to the JDBC
Tutorial (http://developer.java.sun.com/developer/Books/JDBCTutorial/,
section 3.7), the DataSource is intended to replace the DriverManager.
So, if an OracleConnectionPoolDataSource is an implementation of the
DataSource interface, then you should always use it in preference to
DriverManager. See
http://technet.oracle.com/doc/oracle8i_816/java.816/a81354/connpoc1.htm#1047636
and
