Connection Pooling through API

To configure connection pooling through the API, after you make the code changes for connection pooling, override the getPoolingOptions() method in the MetadataAdapter class.

The method sets the following values of the connection pooling attributes:

@Override
    public void getPoolingOptions(ConnectionPoolingOptions options){
            /**
             * The default values are:
    		 * maxTotal = -1
    		 * maxTotalPerKey = -1
    		 * maxIdlePerKey = 20
    		 * MinEvictableIdleTimeMillis = 1200000
    		 * MaxWaitMillis = 30000
    		 */

    	 /* boolean supportPooling = Boolean.FALSE;
    		boolean supportPooling = (System.getProperty(Demo4Connection_CONNECTIONPOOLING_ENABLE) == null
    				|| System.getProperty(Demo4Connection_CONNECTIONPOOLING_ENABLE).isEmpty()) ? Boolean.FALSE
    						: Boolean.parseBoolean(System.getProperty(Demo4Connection_CONNECTIONPOOLING_ENABLE));
    		int maxTotal = (System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXTOTAL) == null
    				|| System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXTOTAL).isEmpty()) ? 0
    						: Integer.parseInt(System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXTOTAL));
    		int maxIdlePerKey = (System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXIDLE_PERKEY) == null
    				|| System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXIDLE_PERKEY).isEmpty()) ? 0
    						: Integer.parseInt(System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXIDLE_PERKEY));
    		int maxTotalPerKey = (System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXTOTAL_PERKEY) == null
    				|| System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXTOTAL_PERKEY).isEmpty()) ? 0
    						: Integer.parseInt(System.getProperty(Demo4Connection_CONNECTIONPOOLING_MAXTOTAL_PERKEY));
    		long minEvictableIdleTime = (System.getProperty(Demo4Connection_CONNECTIONPOOLING_MINEVICTABLE_IDLETIME_MILLIS) == null
    				|| System.getProperty(Demo4Connection_CONNECTIONPOOLING_MINEVICTABLE_IDLETIME_MILLIS).isEmpty()) ? 0
    						: Long.parseLong(System.getProperty(Demo4Connection_CONNECTIONPOOLING_MINEVICTABLE_IDLETIME_MILLIS));

    		if (supportPooling) {
    			options.setSupportPooling(Boolean.TRUE);
    			options.setTestOnBorrow(Boolean.TRUE);
    			//If value is set to zero then we will use default values
    			if (maxTotal > 0)
    				options.setMaxTotal(maxTotal);
    			if (maxIdlePerKey > 0)
    				options.setMaxIdlePerKey(maxIdlePerKey);
    			if (maxTotalPerKey > 0)
    				options.setMaxTotalPerKey(maxTotalPerKey);
    			if (minEvictableIdleTime > 0)
    				options.setMinEvictableIdleTimeMillis(minEvictableIdleTime);
    		} else {
    			options.setSupportPooling(false);
    		}
    		*/
