Applications can also time out the physical and logical connections. Oracle JDBC drivers provide following three types of timeout periods for this purpose: Wait timeout: The maximum period after which a physical connection is returned to the cache. This wait triggers only when all connections are in use and a new connection is requested. A timeout exception, EOJ_FIXED_WAIT_TIMEOUT, is thrown when the timeout expires. You use the getter and setter methods on the property CacheFixedWait Timeout to get and set this timeout. Inactivity timeout: The maximum period a physical connection can remain unused. When the period expires, the connection is closed and its resources are freed. You use the getter and setter methods on the property CacheInactivityTimeout to get and set this timeout. Time to live timeout: The maximum period a logical connection can be active. After this time expires, whether or not the connection is still in use, the connection is closed and its resources are freed. You use the getter and setter methods on the property CacheTimeToLiveTimeout to get and set this timeout.

The following DemoOracleConnectionCache class illustrates how to use Oracle connection caching by using the dynamic and fixed return null cache schemes. We begin with the imports and the class declaration, followed by the main() method: /* This program demonstrates how to use Oracle connection cache. * COMPATIBLITY NOTE: runs successfully against 9.2.0.1.0 and 10.1.0.2.0 */ import java.sql.Connection; import java.sql.SQLException; import oracle.jdbc.pool.OracleConnectionCacheImpl; import book.ch03.JDBCUtil;

The type Rectangle is defined in the .NET library System.Drawing.dll and represents rectangles specified by integer coordinates. The computations on the interior of the transformation are performed in floating point to improve precision. You can use this as follows: > let mapp = remap (Rectangle(100,100,100,100)) (Rectangle(50,50,200,200));; val mapp : Point -> Point > mapp (Point(100,100));; val it : Point = X=50,Y=50 > mapp (Point(150,150));; val it : Point = X=150,Y=150

class DemoOracleConnectionCache { public static void main(String args[]) throws Exception { We instantiate the cache object and set the properties that define the limits and attributes of the cached connections. We also print the default cache scheme. OracleConnectionCacheImpl occi = new OracleConnectionCacheImpl(); occi.setURL ( "jdbc:oracle:thin:@rmenon-lap:1522:ora92" ); occi.setUser("scott"); // username occi.setPassword("tiger"); // password occi.setMaxLimit( 3 ); // max # of connections in pool occi.setMinLimit( 1 ); // min # of connections in pool System.out.println( "By default, the cache scheme is: " + occi.getCacheScheme() ); We then set the cache scheme to dynamic and invoke the method getOneMoreThanMax Connections(). We will see the definition of this method soon, but as the method name suggests, it attempts to get one connection more than the maximum limit of three set previously. This is to see how different cache schemes behave when the limit is exceeded. occi.setCacheScheme( OracleConnectionCacheImpl.DYNAMIC_SCHEME ); int maxLimit = occi.getMaxLimit(); System.out.println( "Max Limit: " + maxLimit ); System.out.println( "Demo of dynamic cache scheme - the default" ); _getOneMoreThanMaxConnections( occi, maxLimit ); We do the same for the cache scheme fixed return null : System.out.println( "\nDemo of fixed return null cache scheme" ); occi.setCacheScheme( OracleConnectionCacheImpl.FIXED_RETURN_NULL_SCHEME ); _getOneMoreThanMaxConnections( occi , maxLimit); }// end of main The method getOneMoreThanMaxConnections() is defined at the end of the program. It simply loops through and tries to create one more than the maximum limit passed to it as a parameter. private static void _getOneMoreThanMaxConnections( OracleConnectionCacheImpl occi , int maxLimit) throws SQLException { //Create an array of connections 1 more than max limit Connection[] connections = new Connection[ maxLimit + 1 ]; for( int i=0; i < connections.length; i++ ) { System.out.print( "Getting connection no " + (i+1) + " ..." );
