Sharing info on MQ Cluster

A cluster is a network of queue managers that are logically associated in some way. In a Web Sphere MQ network using distributed queuing without clustering, every queue manager is independent. If one queue manager needs to send messages to another it must have defined a transmission queue and a channel to the remote queue manager.If you group queue managers in a cluster, the queue managers can make the queues that they host available to every other queue manager in the cluster.

Then, assuming that you have the necessary network infrastructure in place, any queue manager can send a message to any other queue manager in the same cluster without the need for explicit channel definitions, remote queue definitions, or transmission queues.There are two different reasons for using clusters: to reduce system administration and to improve availability and workload balancing.

Use special characters from Windows

Symbols like £ (UK Pound), © (Copyright), ¥(Japanese Yen) can be easily used by following a few simple steps:
1. Firstly, these characters are not provided as keys with the keyboard. So stop staring at the keyboard.
2. Go to Start >> Programs >> Accessories >> System Tools >> Character Map.This opens the Character Map as shown below.
3. This window displays all the possible charaters you can enter.

• Click on any of the symbols to get an enlarged view.
• Then, click on the Select button to select a character.
• To copy the selected symbol, press the Copy button (the symbol is actually copied to the clipboard).

4. That's it! Now you can paste the character where you need it.

Also notice the lower-right corner of the Character Map screen. This displays the keystroke required to produce the character you want.
In the figure above its Alt+0163. This means if you Press and Hold the ALT key and type 0163, you will get the UK Pound symbol.
( NOTE: the numbers must be typed from the keys to the right of your keyboard and NOT from the keys above the character keys).

cfinclude in ColdFusion

cfinclude
Embeds references to ColdFusion pages in CFML.
You can embed cfinclude tags recursively.

Syntax :


ColdFusion searches for included files in the following sequence:
In the directory of the current page
In directories mapped in the ColdFusion Administrator for the included file
The included file must be a syntactically correct and complete CFML page.For example, to output data from within the included page, you must have a cfoutput tag, including the end tag, on the included page, not the referring page. Similarly, you cannot span a cfif tag across the referring page and the included page; it must be complete within the included page.

Program:

Flex Development on Visual Studio

Well, this is came a little late but I think anticipated. Though not from Microsoft itself, but seems developers on Visual studio are also feeling it. After all the noise regarding the new front ends from all around; AJAX, SilverLight, JAVAFX etc, SWF seems to be on top. Here are two more IDEs for SWF development and that to on Flex Framework and on top of Visual Studio. Amethyst and Tofino.

Amethyst comes in 2 flavors Personal and Professional. Personal Edition is Free as well. According to its makers, SapphireSteel Software, The personal edition will be completely free and may optionally be installed into the free Visual Studio ‘shell’ edition. Amethyst Personal (beta) will be available from Amethyst site in the 2nd week of December 2008. Amethyst Professional will be released in beta in the first quarter of 2009 and the final version is expected to ship in the 2nd quarter.

Tofino is from the company named Ensemble . Its ready to be downloaded from their site and as per the company, Ensemble Tofino is available for free.

Technologies to develop Rich Applications

Technologies for building Rich applications:

• Adobe Flex : http://www.adobe.com/products/flex/
• Microsoft Silverlight: http://silverlight.net/
• JavaFX: http://javafx.com/
• OpenLaszlo: http://www.openlaszlo.org/

Building first Flex App

Prerequisites:
1.Download Flex Builder 3 from
http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex3email
2.Install Flex Builder
3.Install Adobe Flash player 9 plugin for Internet explorer

Creating first project in Flex:
1.Run the Flex builder
2.Click on File -> New -> Flex Project
3.In the New Flex Project dialog: >Enter Project Name as "MyFirstApp" >Check the Use Default Location checkbox >Select Web application as Application type >Select Application Server type as None >Click on Finish
4.MyFirstApp.mxml will be opened in the editor
5.In between the tag add the line below, which adds a label with text My First Appin blue color to the application:

Windows tabs Shortcut

Try this shortcut !
Instead of using ALT + TAB,
Try, windows key + TAB.
Press ENTER to open the active window

END task in windows

If an application or a page is hanged, normally we would go to task manager and select that application or page and then we would click on End Task !
It would take sometime to end that application, we got look at the hanged monitor till it closes it and then resume our work.
But, do we know that we have an easier way to close that application ?
Here is it !
Goto the task manager window, and select the Processes tab, and then select the corresponding process and say end process.
It will immediately close it !
The only difficulty is, to find the corresponding process.
The key is that the process would be named in relation to the application.
For eg : notepad.exe, OUTLOOK.EXE, iexplore.exe ( Browser window )
You will get used to finding the process, once you start using it !

Unix Command on sessions

Unix command to check all the active sessions which are currently running.
ps –ef grep rts
ps : Reports the process status
-e: List information about every process now running.
-f: Generate a full listing
rts:Request To Send, RTS is a signal sent by a communications device, such as a modem, to verify if the other device is ready for data to be sent to it.

If you have some issues in unix for example like “license on the server expired”, by giving the above command you can find all the active sessions running on that server.So by killing all the unused or expired sessions your issue may be resolved.Command to kill the session
kill %pid
Kill: cancels a job
Pid-A job control job ID that identifies a background process group to be signaled.

Reading a zip file

This sample code read the name of all files from a zip file. It uses ZipInputStream to read zip file.


import java.io.*;
import java.util.zip.*;

public class ZipFileRdrExp {

public static void main(String[] args) {

try {

FileInputStream fis = new FileInputStream("C:\\MyZip.zip");
ZipInputStream zis = new ZipInputStream(fis);
ZipEntry ze;
while((ze=zis.getNextEntry())!=null){
System.out.println(ze.getName());
zis.closeEntry();
}

zis.close();

} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
