the following example, typically through a third-party
connection pool tool:
Context ctx = new InitialContext();
ConnectionPoolDataSource ds =
(ConnectionPoolDataSource)ctx.lookup(“jdbc/EmployeeDB”);
pooledConnection pcon = ds.getPooledConnection(“scott”, “tiger”);
In this example, the JNDI environment is first initialized. Next, the
initial naming context is used to find the logical name of the
JDBC data source (EmployeeDB). The Context.lookup() method
returns a reference to a Java object, which is narrowed to a
javax.sql.ConnectionPoolDataSource object. Finally, the
ConnectionPoolDataSource.getPooledConnection() method is
called to establish a connection with the underlying database.
The DataDirect Connection Pool Manager is part of DataDirect
Connect for JDBC. See Appendix G “Connection Pool Manager” on
page 263 for details.
Specifying Connection Properties
You can specify connection properties using the JDBC Driver
Manager or DataDirect Connect for JDBC data sources. See “URL
Examples” on page 28 for information about specifying
properties through the Driver Manager. See “Creating Data
Sources” on page 31 for information about example data sources
that specify connection properties.
For the list of the connection properties specific to each
DataDirect Connect for JDBC driver, see the appropriate driver
chapter.
