IBM XPages Performance Masterclass

From October, 17-18th, XPages Performance MasterClass took place at the IBM Labs in Dublin, Ireland. The event was sponsored by IBM; only transportation and hotel had to be paid by attendees.

40+ people from all over Europe ( Germany, Austria, Italy, Greece, Sweden, Czech Republic … ) gathered together for all things XPages Performance optimization.

Maire Kehoe, Martin Donnelly and Tony McGuckin did an excellent job sharing their knowledge. They provided  4 deep dive sessions each of the two days,  covering all aspects of the JSF lifecycle, partial refresh / exectution mode, design patterns and Java debugging, just to name a few of many topics.

Eamon Muldoon from IBM Ireland said, that his team setup this masterclass on top of their daily job. Aside from preparing the next major release launch and working on PMRs and also new stuff, they prepared all the content, slides and samples to cover almost 16 hours.

All I can say after 2 days packed with first class information is “Thank You!!”.  It was great to have the opportunity to attend this event.

 

 

Access AVM FRITZ!Box 7390 PhoneCall In/Out Information from Java

AVM Fritz!Box provides a phone call monitor. To access the information, you have to activate Port 1012 in the Box. The setting is not available from the GUI, but you can use your phone to switch the feature on and off.

Dial #96*5* to enable the call monitor (  #96*5* to disable ).

To access the information via telnet for example, you also have to enable telnetd in your FRITZ!Box . Dial #96*7* to enable the telnetd (  #96*8* to disable ).

Here is some simple code that monitors the phone call manager via telnet on port 1012

package de.eknori.test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.Socket;

public class CallMonitor {
	public static void main(String[] argv) {
		new CallMonitor().getCall("192.168.178.1", 1012);
	}

	private void getCall(String host, int portNum) {

		System.out.println("Host " + host + "; port " + portNum);
		try {
			Socket s = new Socket(host, portNum);
			new Pipe(s.getInputStream(), System.out).start();
			new Pipe(System.in, s.getOutputStream()).start();
		} catch (IOException e) {
			System.out.println(e);
			return;
		}
		System.out.println("Connected OK");
	}

	/**
	 * This class handles one half of a full-duplex connection.
	 */
	class Pipe extends Thread {
		BufferedReader is;
		PrintStream os;
		Pipe(InputStream is, OutputStream os) {
			this.is = new BufferedReader(new InputStreamReader(is));
			this.os = new PrintStream(os);
		}

	}
}

When you run the code, you will see something like this as an output

* 14.10.12 10:56:19;CALL;1;10;XXX5670;XXX8506;SIP0;
* 14.10.12 10:56:19;RING;2;02104XXX5670;XXX8506;SIP2;
* 14.10.12 10:56:21;DISCONNECT;2;0;
* 14.10.12 10:56:21;CONNECT;1;10;XXX8506;
* 14.10.12 10:56:24;DISCONNECT;1;4;
* 14.10.12 10:56:21;RING;0;02104XXX5670;XXX8506;SIP2;
* 14.10.12 10:56:21;CONNECT;0;5;02104XXX5670;
* 14.10.12 10:56:24;DISCONNECT;0;4;
